Abstract
BACKGROUND Tumors protruding into the cerebral aqueduct are rare, and tumors arising from within the cerebral aqueduct are rarer still. CASE DESCRIPTION In this report, we discuss the presentation and clinical outcome of a 65-year-old man who presented to us with symptoms of hydrocephalus. Prior imaging had revealed a small enhancing nodule within the cerebral aqueduct. In the 6 months between initial imaging and our seeing the patient, the tumor demonstrated substantial interval growth, so the patient was offered resection. The tumor was accessed using a sitting, supracerebellar, intracollicular approach, which allowed for gross total resection of the mass without complication. Histopathology later revealed the lesion to be a hemangioblastoma. Two years after surgery, the patient was doing well with no neurologic deficits. CONCLUSIONS We report the first case of an aqueductal hemangioblastoma and describe our use of a sitting, supracerebellar, intracollicular approach to access tumors occupying this cerebrospinal fluid space.

Abstract
BACKGROUND von Hippel-Lindau disease-related hemangioblastoma is likely to occur in the cerebellum and accompany a cyst. As multiple hemangioblastomas commonly occur in von Hippel-Lindau disease, and multiple surgeries may thus be necessary, a minimally invasive surgical strategy is of great importance. METHODS We present 2 patients with von Hippel-Lindau disease-related hemangioblastomas successfully treated by a fully endoscopic transcranial approach via a short skin incision and a 2 cm × 2 cm small bony window. Before surgery, a three-dimensional virtual reality model was created to determine the ideal trajectory. RESULTS Patient 1 had 2 serial large cystic tumors that equally contributed to obstructive hydrocephalus and were resected sequentially via a single endoscopic trajectory. Patient 2 had a progressive large cystic tumor that was resected endoscopically. Complete resection of the tumors was achieved without any complications in either patient. CONCLUSIONS Small nodular tumors accompanying a large cyst are plausible candidates for endoscopic transcranial surgery. The spatial relationship of nodules, cyst, and cerebellar parenchyma is important to determine the applicability of the present technique. Preoperative three-dimensional virtual reality simulation helps assess the feasibility of this approach.

Abstract
RATIONALE Hemangioblastoma is a rare tumor of the central nervous system (CNS). It is usually observed in patients with von-Hippel Lindau (VHL). The peak age for hemangioblastoma is between 20 and 50 years of age with very few cases over 65 or below 18 years of age. PATIENT CONCERNS We report a female with a rare VHL mutation (c.337C>T) who was diagnosed with multifocal CNS hemangioblastoma at a very young age. DIAGNOSIS At 17-years of age, she presented with obstructive hydrocephalus due to large cystic cerebellar mass. Imaging showed multiple lesions resembling drop metastases throughout her spinal cord. Immunohistochemistry of the resected tumor confirmed the pathological diagnosis of hemangioblastoma (World Health Organization Grade 1). INTERVENTIONS AND OUTCOME She was treated with multi-stage resection of her primary and drop- metastasis like disease. She presented six months later with retinal hemangioblastoma while her other lesions were stable. She presented with multiple CNS and eye hemangioblastomas after failing to follow up for 2 years. Subsequently, Everolimus was started to treat her systemic disease. LESSONS The unique feature of our case is the presence of multiple drop-metastases like spinal lesions, which has not been reported in the literature to be associated with hemangioblastoma.

Abstract
Brainstem tumors are uncommon beyond childhood. Controversies arise regarding the need of histological diagnosis in this eloquent area of the brain, weighting the benefits of a reliable diagnosis against the disadvantages of invasive procedures. There are scant publications about the surgical management of brainstem tumors in adults, all of them involving small retrospective cohorts. We are reporting our experience with the aim of contributing to the decision making process. Out of a series of 13 patients, 10 were approached surgically. According to Guillamo's classification the lesions were: focal (n:7), diffuse infiltrative (n:1), tectal (n:1), and exophytic (n:1). According to the Karnofsky Performance Status scale, the neurological status was = 70 in 6 cases and < 70 in 7. Histopathology was confirmed in all 10 treated cases and the samples were obtained by a direct microsurgical approach or by stereotactic biopsy. Histopathological findings were: pilocytic astrocytoma (n:1), low grade glioma (n:1), glioblastoma (n:1), cellular haemangioblastoma (n:1), subependimoma (n:1), pseudotumoral lesions (n:4; 3 cavernomas, 1 inflammatory pseudotumor), and disgerminoma (n:1). As a broad variety of pathologies could be found in this brain localization, an accurate histopathological definition can not only determine the adequate therapy, but also avoid the disastrous consequences of empiric treatments.

Abstract
BACKGROUND Pediatric hemangioblastomas are rare, and the clinical features, timing of surgical intervention, optimal treatment, and clinical outcomes are still unclear. METHODS We performed a retrospective study of all patients with CNS hemangioblastomas who were treated at West China Hospital from January 2003 to March 2015. Patients under the age of 16 years were included in the study. The medical records of these patients were reviewed and statistically analyzed. RESULTS Twenty-five children (15 females and ten males, [mean age 12.6 ± 4.7 years, range 1-16 years]) presented with hemangioblastomas. Tumors were detected in the cerebellum, brainstem, and spinal cord in 40, 28, and 32% of patients, respectively. Sixteen children (64%) had VHL syndrome. The most frequent symptoms were those related to increased intracranial pressure. The mean duration of symptoms was 1.5 ± 2.1 months. Preoperative hydrocephalus was noted in 11 children (44%). Gross total resection was achieved in all children. Clinical symptoms improved in 19 children (76%), unchanged in four children (16%), and aggravated in two children (8%), respectively. The mean follow-up was 44.5 ± 32.3 months. Five patients (20%) experienced disease progression. Using univariate analysis, both tumor-associated cysts (P = 0.027) and VHL disease (P = 0.032) were significantly related to postoperative outcomes. CONCLUSIONS Pediatric hemangioblastomas have many different clinical features compared with adult cases. A high degree of suspicion for VHL disease should be raised in pediatric hemangioblastomas. Despite many challenges involved, surgical outcomes for pediatric hemangioblastomas are favorable. Lifelong follow-up is mandatory to detect the disease progression.

Abstract
BACKGROUND As the anatomical three-dimensional (3D) positional relationship around the anterior clinoid process (ACP) is complex, experience of many surgeries is necessary to understand anterior clinoidectomy (AC). We prepared a 3D synthetic image from computed tomographic angiography (CTA) and magnetic resonance imaging (MRI) data and a rapid prototyping (RP) model from the imaging data using a 3D printer. The objective of this study was to evaluate anatomical reproduction of the 3D synthetic image and intraosseous region after AC in the RP model. In addition, the usefulness of the RP model for operative simulation was investigated. METHODS The subjects were 51 patients who were examined by CTA and MRI before surgery. The size of the ACP, thickness and length of the optic nerve and artery, and intraosseous length after AC were measured in the 3D synthetic image and RP model, and reproducibility in the RP model was evaluated. In addition, 10 neurosurgeons performed AC in the completed RP models to investigate their usefulness for operative simulation. RESULTS The RP model reproduced the region in the vicinity of the ACP in the 3D synthetic image, including the intraosseous region, at a high accuracy. In addition, drilling of the RP model was a useful operative simulation method of AC. CONCLUSIONS The RP model of the vicinity of ACP, prepared using a 3D printer, showed favorable anatomical reproducibility, including reproduction of the intraosseous region. In addition, it was concluded that this RP model is useful as a surgical education tool for drilling.

Abstract
BACKGROUND Posterior fossa hemangioblastomas are WHO grade I benign lesions with a surprisingly high recurrence rate. This study determines the factors responsible for recurrence and the clinico-radiological and histopathological differences between primary (group A; n = 60) and recurrent/symptomatic residual (group B; n = 24) tumors. METHODS Radiologically, tumors were differentiated into cystic, cystic with a mural nodule, solid-cystic/microcystic and solid. Surgery was undertaken via a midline or lateral suboccipital approach. Histopathology differentiated them into reticular, cellular or mixed subtypes. RESULTS Truncal-appendicular ataxia in group A and von Hippel-Lindau (VHL) disease and raised intracranial pressure in group B were the predominant presentations. VHL patients in group B had a longer duration of symptoms (median 72 months) than those with non-VHL recurrences (median: 36 months). Multicentric mural nodules (n = 9/24, 37.50%, P = 0.0001) and bilateral cerebellar hemispheric involvement (n = 6/24, 25%, P = 0.0003) were exclusively seen in the preoperative radiology of group B tumors. Brainstem involvement was seen in the tumors of ten (16.67%) patients in group A and six (25.00%) patients in group B. One subset of patients required several resurgeries for repeated recurrences. Abnormal vascular proliferation and papillary projections into adjacent brain, and highly cellular stroma were unique histological features at recurrence. Total resection was achieved in 45 group A and 19 group B patients. The outcome based on the Karnofsky performance scale (KPS) was assessed at follow-up at 6 weeks (A: n = 60, B: n = 24): KPS0: A = 4, B = 1; KPS10-40 (dependent): A: 4, B = 5; KPS50-70 (independent for daily needs): A = 36, B = 16; KPS80-100 (fully independent): A = 16; B = 2. CONCLUSIONS In recurrent/residual tumors, the radiological as well as histopathological features showed a distinctive change toward a more aggressive nature. Higher incidences of multiple mural nodules, bilateral spread, remote recurrence and VHL disease at preoperative radiology; as well as proliferative angioarchitecture, an irregular brain tumor interface and highly cellular stroma at histology were found in these patients compared to their primary counterparts.

Abstract
Hemangioblastomas are rare vascular tumors most often found in the posterior fossa and cervical spinal cord and commonly associated with von Hippel-Lindau Disease. We report a case of sporadic hemangioblastoma in a patient without von Hippel-Lindau Disease. Imaging characteristics included a solid, suprasellar mass that was homogeneously enhancing. These findings most resembled a pituicytoma or choroid glioma because of the close association with the infundibulum and the homogeneous avid enhancement. Microscopically, the neoplasm was seen to be composed of vascular channels associated with foamy stromal cells, containing clear cytoplasmic vacuoles. Microscopic and immunohistochemical findings were consistent with hemangioblastoma. Hemangioblastomas are a rare form of vascular tumor most commonly associated with von-Hippel Lindau disease. Our finding of non-cystic hemangioblastoma arising from the infundibulum demonstrates that, while rare, hemangioblastomas should be considered on the differential diagnosis for an avidly enhancing suprasellar mass.

Abstract
OBJECTIVES Hemangioblastomas in the cerebellopontine angle (CPA) are uncommon and have rarely been reported. They may be easily misdiagnosed because of the atypical location and clinical and imaging features. The present study aimed to characterize clinical and radiologic features, treatment strategies, and outcomes in these rare lesions and to investigate various factors that may affect postoperative outcomes. METHODS The medical records of patients with CPA hemangioblastomas who underwent surgery from 2003-2016 at the West China Hospital were reviewed retrospectively and statistically analyzed. RESULTS Twenty-three patients (14 males and 9 females) presented with CPA hemangioblastomas. Eight patients (34.8%) had von Hippel-Lindau (VHL) syndrome. Gross total resection was achieved in 22 patients (95.6%). The mean follow-up was 45.1 ± 36.2 months (range 3-144 months). After surgery, the symptoms improved in 18 cases (78.3%), remained unchanged in 3 cases (13%), and were aggravated in 2 cases (8.7%). Four patients showed local recurrence during follow-up (17.4%). Patients with cystic hemangioblastomas had a better neurologic improvement (P = 0.041) compared with patients with solid tumors. Furthermore, patients with maximal diameter of tumors >3 cm (P = 0.035) or solid tumors (P = 0.018) showed a higher incidence of postoperative complications. The local recurrence was correlated with VHL disease (P = 0.027). CONCLUSIONS Although hemangioblastomas of the CPA are challenging lesions to treat surgically, they can be removed safely when these lesions are appropriately diagnosed and treated. Patients with VHL disease are more likely to have a local recurrence. A regular follow-up is recommended to detect the local and distant recurrence, even if the clinical course is benign and the tumor is totally resected.

Abstract
Hemangioblastoma disseminated along leptomeninges from the solitary cranial lesion without von Hippel-Lindau (VHL) disease is a quite rare instance with 23 cases reported in 40 years. We add a new case and discuss these rare instances. A 55-year-old female underwent surgery for total removal of cerebellar hemangioblastoma. Twenty months later, magnetic resonance (MR) images of the spinal cord revealed a tumor compressing the thoracic cord at T3-4 level which was removed en bloc by emergent spinal surgery. However, paraplegia and bowel bladder dysfunction recurred 5 months after the spinal surgery. Spine MR images showed diffuse enhancement of subarachnoid space. Exploratory surgery disclosed that the enhanced lesion was disseminated hemangioblastoma. After whole spinal irradiation, she was transferred to a palliative care hospital. Even after complete removal, possibility of leptomeningeal dissemination demands continuous follow-up. The mechanism of seeding of hemangioblastoma remains unclear, but attention must be paid to avoid spreading tumor cells during surgery because all the disseminated cases had precedent cranial surgery.

Abstract
OBJECT Hemangiobastomas (HB) are rare lesions accounting for 1 to 5% of all spinal cord tumors. Due to their hypervascular nature, an angiography may be proposed preoperatively in order to identify tumoral vascular anatomy. Preoperative embolization may be indicated to reduce intraoperative bleeding, thus facilitating tumor resection and minimizing surgical risk. The aim of this paper is to report our experience of preoperative embolization in intramedullary hemangioblastomas. METHODS We performed a retrospective analysis of all patients operated on for intramedullary hemangioblastomas between 1995 and 2014 who had undergone embolization before surgery. RESULTS Seven patients were analyzed: there were 6 females and 1 male, mean age 43years, 6 patients had Von Hippel-Lindau disease. Four tumors were located in the cervical spine and three in the dorsal spine. The average maximum sagittal diameter was 19mm (range 8-32mm), while the average maximum axial diameter was 11.5mm (range 6-21mm). The embolic agent used was Histoacryl (NBCA). Endovascular embolization was routinely performed the day before surgery. One patient experienced a major preoperative complication with a vertebrobasilar infarctus with consequent unilateral cerebellar syndrome and gait instability. Minor extravasation of embolic agent was observed in two cases. In one of these two cases, there was also the penetration of the embolic agent in the tumor; the resection was impossible due to the hard consistency of the tumor. In the other 6 patients, the resection was total. Six patients had identical preoperative and postoperative McCormick score and one patient shifted to a better score at follow-up. CONCLUSION Preoperative endovascular embolization is an effective adjunct treatment. It is useful in reducing the surgical bleeding and thus the operative risks. The procedure is not always safe and complications could occur. We recommend preoperative embolization in selected cases.

Abstract
Hemangioblastoma (HBL) in the pituitary stalk is extremely rare. Only 16 such cases have been reported in the past and 5 cases have been treated with surgical procedure. Here, we report surgical case of HBL in the pituitary stalk diagnosed in a 34-year-old woman. The patient underwent a gross-total resection via the modified lateral supra-orbital approach. No recurrence was observed in two years after surgery. To our knowledge, this is the 17th case of HBL in the pituitary stalk and the 6th surgical case. If the tumor is symptomatic and the volume is over 5 cubic centimeters as in our case, we recommend that the surgical resection of the HBL in the pituitary stalk is a more safe and reasonable than radiotherapy.

Abstract
Hemangioblastoma is a rare CNS vascular tumor that develops sporadically and can also be associated with von Hippel-Lindau disease. Hemangioblastomas account for 2-6% of all spinal cord tumors and are ranked third in the structure of intramedullary space-occupying lesions of the spinal cord. For the first time in our practice, we observed a dumbbell paravertebral hemangioblastoma. The international literature reports only 3 cases of the tumor with this growth type.

Abstract
BACKGROUND The aim of this work is to evaluate the utility of multimodal intraoperative monitoring (IOM) during intramedullary spinal cord tumor (IMSCT) surgery in our institution, and to investigate which IOM events are likely to be encountered during critical surgical phases. METHODS Twenty-five patients who underwent IMSCT surgery with IOM were included in this study. Our multimodal IOM assessment included SSEP, mMEP, and fEMG monitoring. Positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity were assessed 24 h and 1 month after surgery. The IOM events during three main surgical phases were also investigated. For mMEP assessment, two warning criteria (>50 % decrease in mMEP amplitude and all-or-none mMEP amplitude presence) were employed. RESULTS Long-term outcome prediction was better when the all-or-none criterion was applied than when the >50 % amplitude decrease criterion was applied. Based on the all-or-none criterion, the PPV, NPV, sensitivity, and specificity were 60, 100, 100, and 91 %. Frequent IOM events were observed during the three major main surgical phases. Seven (29 %) patients showed SSEP events during opening of the spinal cord. During tumor removal, 21 of 25 patients (84 %) had IOM events, and 13 of 18 (72 %) of the fEMG events occurred prior to the mMEP events. CONCLUSIONS Based on the association of fEMG events with upcoming mMEP events during tumor removal, we recommend inclusion of fEMG monitoring in IOM. Multimodal IOM provides useful electrophysiological information during IMSCT surgery, especially during the main surgical phases.

Abstract
Suprasellar hemangioblastoma (HBL) without von Hippel-Lindau (VHL) disease is extremely rare. A 51-year-old woman presented with headache and progressively deteriorating bilateral visual disturbance for 4 months. Magnetic resonance imaging (MRI) revealed a 2.5-cm solid mass in the suprasellar region with homogeneous contrast enhancement. Our preoperative presumptive diagnosis was meningioma. Resection of the tumor was achieved via a left pterional craniotomy. The tumor was reddish in appearance and relatively firm, and was extremely vascularized, which might provide extensive blood supply through small branches of the internal carotid artery. There was a clear border between the tumor and the pituitary stalk and optic nerves. Histopathologic examination showed that the tumor was well vascularized, consisting of a reticular mesh of numerous thin-walled capillaries and abundant stromal cells. Immunohistochemistry demonstrated the positive staining for CD34, vimentin (VIM), and neuron specific enolase (NSE) in the intratumoral capillaries, while negative staining of epithelial membrane antigen (EMA) and glial fibrillary acidic protein (GFAP) was observed. Based on these results, the patient was diagnosed as HBL. After the resection, the visual field defect in the left eye was markedly improved, and no tumor recurrence was noted in 1 year follow-up. When solid lesions are highly vascularized in the suprasellar region of patients, even though no VHL disease is present, the possibility of HBL should be taken into consideration. Moreover, craniotomy is a better treatment option for suprasellar HBL without VHL disease.

Abstract
BACKGROUND We describe the resection of cerebellar cystic tumors using pure neuroendoscopy. This technique consists of performing all of the procedures under an endoscopic view, with the instruments introduced into the operative field coaxially to the endoscope through a trocar. CASE DESCRIPTION Three cases of cerebellar cystic lesions (two pilocytic astrocytomas and one hemangioblastoma) were approached using the pure neuroendoscopic technique. Under general anesthesia and prone positioning, a suboccipital burr hole was created. The endoscope was introduced into the tumor cavity, and a reddish nodule was identified. The monopolar electrode was used to coagulate and dissect the surrounding nodular tissue. Grasping forceps were used to remove the nodule. There were no complications related to tumor removal, and the patients recovered from their symptoms. The follow-up images showed reduction of the cavity with no contrast enhancement. CONCLUSION The pure neuroendoscopic technique was shown to be minimally invasive and a successful and secure method to treat cystic cerebellar tumors.

Abstract
Spontaneous hemorrhage is rarely associated with hemangioblastomas. Intratumoral hemorrhage occurring in cerebellar hemangioblastomas is more rare. A 25-year-old man was admitted to our hospital with headache. We found a round cystic lesion with solid part in the right cerebellum. The lesion was resected. The final pathological diagnosis was hemangioblastomas. The radiological features of this case were similar to normal hemangioblastomas, whereas our histological examination showed the occurrence of the intratumoral hemorrhage. If the hemangioblastoma ruptures in our case, the outcome of the patient will be worse. It is difficult to identify the intratumoral hemorrhage of hemangioblastomas and quite dangerous if it is diagnosed late. Diagnosing an intratumoral hemorrhage of hemangioblastomas still needs a further discussion. Genetic screening may help us make an early diagnosis. Furthermore, the mechanism about intratumoral hemorrhage of hemangioblastomas remains unknown. The mutation of D6Mit135 gene on chromosome 6 may be responsible for the vascular dilation and hemorrhage induction in the hemangioblastomas. Tumor size, upregulation of vascular endothelial growth factor, spinalradicular location, and solid type are also factors relating to the hemorrhage of hemangioblastomas. The purpose of reporting our case is 2-fold: to remind clinicians to consider the possibility of internal hemorrhaging while diagnosing this disease, and provide a starting point to discuss mechanisms regarding the intratumoral hemorrhage of hemangioblastomas.

Abstract
Recent publications have reported stereotactic radiosurgery as an effective and safe treatment for intracranial hemangioblastomas. However, because of the low incidence of these particular tumors, reports on large patient number studies have not yet been available. The objective of this study was to analyze the clinical results of 14 patients with 56 intracranial hemangioblastomas treated with linear accelerator (linac)-based stereotactic radiosurgery (SRS) and radiotherapy (SRT) in the same institute. The median age of patients was 41 years (range, 28-73 years). Nine of the patients (64%) had von Hippel-Lindau disease. A total of 39 lesions (70%) were treated with CyberKnife (CK), and 17 lesions (30%) were treated with X-Knife. The median pretreatment volume was 0.26 cm(3) (range, 0.026-20.4 cm(3)). The median marginal dose was 20 Gy (range, 10-32 Gy) in 1 fraction (range, 1-10 fractions). The median follow-up time was 24 months (range, 11-89 months). At the last follow-up, 47 tumors (84%) were stable, 7 (13%) decreased and 2 (4%) increased. The 1-, 2- and 6-year local control rates were 98%, 88% and 73%, respectively. No radiation complications were observed in this study. There was a trend toward local failure only in cystic tumors, but this trend was not found to be statistically significant. SRS/SRT achieved a high local control rate in intracranial hemangioblastomas without radiation-induced complications.

Abstract
The authors described a case of a patient with co-existing endolymphatic sac tumor (ELST) and hemangioblastoma in the posterior cranial fossa, which belonged to a subtype of Von Hippel-Lindau (VHL) disease confirmed by the test of VHL-gene. The signs in this 42-year-old female included intermittent headache and dizziness. Imaging revealed a giant mass in the right cerebellopontine angle (CPA) region and another lesion in the left cerebellar hemisphere. The results of biopsy after two operations confirmed the diagnosis respectively. Both of the tumors were resected totally. Nevertheless, we had to confess the misdiagnosis as vascular tumor instead of ELST at the initial diagnosis because of the rarity of ELST associated with atypical histological characteristics. The purposes we reported this case were to describe the atypical pathological feature of ELST and the mutation of germline VHL not mentioned in previously literature, furthermore, to foster understanding of ELSTs with the avoidance of the similar misdiagnosis as far as possible in future.

Abstract
Hemangioblastoma is a rare neoplasm occurred in soft tissue. Herein, we present an intriguing case of sporadic hemangioblastoma in the retroperitoneum occurring in a 59-year-old male. The tumor was characterized by an alternation of cellular and paucicellular areas surrounded by a thick fibrous capsule. The stromal cells showed a pale cytoplasm exhibiting occasional lipid droplets and hyperchromatic, irregularly nuclei. CD56, NSE, a-inhibin and S100 were positive in tumor cells. This is the third reported case of a hemangioblastoma in the retroperitoneum. Based on clinical examination, computed tomography imaging, surgical operation, and histopathologic studies, a definitive diagnosis was made. Further characteristic images and pathology of this disease are discussed.

Abstract
OBJECTIVE To investigate the clinicopathological characteristics of sporadic renal hemangioblastoma. METHODS Two cases of sporadic renal hemangioblastoma were studied by histological and immunohistochemical staining, along with review of the literature. RESULTS Both cases were presented with a renal mass during annual physical examination with an age of 40 and 45 years, respectively. The lesions located in the middle portion of the kidney with a sharp tumor border. Histopathologically, the tumors were characterized by two major components: capillary and stromal cells. Immunohistochemically, the stromal cells were positive for vimentin, NSE, S-100 protein and inhibin-α, and negative for CK, HMB45, Melan A, EMA, CD56 and syn. Both tumors showed a very low level of Ki-67 labeling. The endothelial cells were positive for CD34. CONCLUSION Sporadic renal hemangioblastoma is a rare benign neoplasm, the diagnosis of which is based on the characteristic follicular architecture and an exclusion of other carcinomas of the kidney.

Abstract
Brain tumors can rarely present with symptoms mistaken for anorexia nervosa. We report a patient with a long-standing history of anorexia who developed headaches and was found on brain MRI to have a brain tumor in the area of the fourth ventricle. On admission, the patient presented with a 4 month history of headaches and a 10 year history of "anorexia nervosa". Interestingly, the patient did not endorse the classic sense of an altered self-body image. Her body weight on admission was 37 kg. The patient underwent surgical resection of the tumor. On postoperative day (POD) 1, the patient subjectively reported an increased appetite. On POD 2, we documented that she finished her entire food tray for the first time during her hospital stay. Her peri-operative course was without any complications. She presented for a follow-up clinic visit 2 weeks postoperatively and was noted to have a new body weight of 47 kg (10 kg gain). To our knowledge, this is the first reported occurrence of a sporadic, and third overall occurrence, of a hemangioblastoma that presented with an anorexia nervosa-like syndrome that was ultimately cured with surgical resection. In patients presenting with a history of psychiatric illness, it is important to consider the possibility of underlying, organic pathologies in the central nervous system affecting the relevant neuro-anatomical domains.

Abstract
OBJECTIVE To explore the clinical characteristics, diagnostic strategies and surgical techniques of hemangioblastoma (HB) in medulla oblongata. METHODS The clinical and radiological characteristics, therapeutic processes and outcomes of 12 HB cases treated at our department from 2002 to 2012 were studied by retrospective analysis. RESULTS Headache, somatic numbness and limb muscle weakness were the major symptoms of oblongata HB. Magnetic resonance imaging before surgery revealed a total of 12 single tumors. Among these tumors, upper (n = 1), middle (n = 7) and lower (n = 4) parts of medulla oblongata were involved. The locations were surface (n = 9) and intramedullary (n = 3). Three tumors had cyst. Digital subtraction angiography (DSA) was performed on 5 cases and it revealed that the main blood supply arteries of tumors were branches of posterior inferior cerebellar artery (PICA) and anterior inferior cerebellar artery (AICA).One case underwent pre-surgical embolism during angiography. Eleven tumors were totally resected and 1 was fulgurized.Symptoms improved (n = 8) and worsened (n = 2). And two patients died. All survivors were followed up for 3 months to 10 years and had a McCormick functional grading of I-II.One case relapsed 7 year later. CONCLUSION For Cystic HB, small or medium sized substantial HB in middle and lower part of oblongata, surgical removal is often safe and symptoms may be lessened.It can be used as a first-line treatment. For large ( ≥ 3 cm) substantial HB or HB in upper part of oblongata, serious postoperative complications such as respiratory failure, neurogenic pulmonary edema or acute obstructive hydrocephalus may occur. Thus surgical resection should be prudently considered and possible consequences thoroughly discussed with the patients.

Abstract
In this study, we presented an additional case of renal hemangioblastoma, which demonstrates PAX2 and focal CD10 expression. Histologically, the tumor consisted of sheets of oval or polygonal cells and a prominent vascular network. The tumor cells varied in size, and possessed pale or eosinophilic cytoplasm that sometimes contained sharply delineated fine vacuoles. The tumor cell nuclei with inconspicuous nucleoli showed moderate nuclear atypia and pleomorphism. Focal areas of stromal hyalinization and sclerosis were detected. On account of its strong or moderate immunoreactivity for the a-inhibin, S100, NSE, and EGFR, the diagnosis of renal hemangioblastoma was established. For further evidence of VHL deficiency, the tumor was subjected to VHL sequence analysis of all three exons and fluorescence in situ hybridization (FISH) detection for chromosome 3p deletion. None of the VHL gene mutations and chromosome 3p deletion was detected in the tumor. Because of several shared morphological and immunophenotypic features, renal hemangioblastoma may be underrecognized and should be included in the differential diagnosis of primary renal tumors, in particular clear cell renal cell carcinoma. The unexpected positive staining of PAX2 and CD10 in renal hemangioblastoma should be particular concerned. Using a combination of immunoprofile may be helpful to the differential diagnosis of these renal tumors.

Abstract
Hemangioblastoma is a benign, morphologically distinctive neoplasm of disputed histogenesis that typically occurs in the central nervous system either in the setting of von Hippel-Lindau disease or more often sporadically. Extraneural hemangioblastoma is exceptional and raises a challenging differential diagnosis. Herein, we report a primary renal hemangioblastoma occurring in 51-year-old woman without stigmata of von Hippel-Lindau disease. Histologically, the tumor was composed of sheets of polygonal epithelioid stromal cells with ample pale or eosinophilic, vacuolated cytoplasm in an arborizing capillary network. Tumor cells showed variable nuclear pleomorphism, intranuclear cytoplasmic invaginations, scattered hyaline globules, and psammoma-like calcifications. Some areas showed branching hemangiopericytoma-like vessels with tumor cells radiating from the wall, while other areas were edematous and hyalinized with sparse stromal cells and abundant reticular vessels. Immunohistochemically, the tumor cells reacted strongly and diffusely with antibodies to PAX8, CD10, α-inhibin, S100 protein, neuron-specific enolase, and vimentin, and they showed focal positivity with antibodies to epithelial membrane antigen and AE1/AE3. Tumor cells were negative for CK7, CK8/18, RCC antigen, synaptophysin, chromogranin, c-kit, D2-40, HMB45, melan-A, cathepsin K, SMA, desmin, CD31, CD34, and estrogen and progesterone receptors. Positive immunoreactivity for PAX8 is unexpected and contrasts to central nervous system (CNS) hemangioblastomas, which are essentially always negative for PAX8. This novel finding adds support to the hypothesis that the immunoprofile of extraneural hemangioblastoma varies with site of origin, perhaps as a result of tumor cell lineage and retention of organ-specific markers or acquisition of site-specific antigens due to local factors.

Abstract
BACKGROUND Resection of hemangioblastomas can be challenging due to their high vascularity and intimate association with neighboring cerebrovascular structures. The authors present their intraoperative findings using fluorescein angiography and fluorescence for removal of hemangioblastomas in an attempt to improve the safety and extent of resection. METHODS From April through August 2012, four patients were diagnosed with hemangioblastomas, 3 in the cerebellum and 1 in the medulla oblongata. Low-dose (4 mg/kg) sodium fluorescein was injected intravenously immediately before microdissection. The area of interest was inspected through a microscope-integrated fluorescent module. RESULTS In three superficially located tumors, the vascular pattern of feeding and draining vessels could be easily identified with fluorescein angiography. The resection of the tumors was guided using real-time fluorescence mode. For each patient, histopathologic examination of the lesion confirmed the diagnosis of hemangioblastoma. All samples of fluorescent tissue resected were confirmed to contain tumor. No patient experienced any complication. CONCLUSION Low-dose sodium fluorescein used in conjunction with a microscope-integrated fluorescence module is a potentially useful tool for localization, vascular characterization, and resection of hemangioblastomas.

Abstract
BACKGROUND Haemangioblastomas are benign vascular tumours that may appear sporadically or in von Hippel-Lindau disease. Despite their higher incidence, sporadic haemangioblastomas have been less studied than syndromic ones. In this article, we evaluate the specific features, outcome and quality of life of patients with intracranial sporadic haemangioblastomas (ISHs) operated on in our institution. METHODS Between 1998 and 2010, 38 patients harbouring 38 ISHs were operated on in our department. Their clinical, biological, radiological and surgical features were retrospectively reviewed. All patients were contacted for a quality-of-life (QOL) survey assessed by the Short Form 36 questionnaire (SF36). The mean duration of follow-up was 40 months (13-108 months). RESULTS ISH represented 0.9 % of primary intracranial neoplasms treated in our centre during this period. Patients comprised 23 men and 15 women with a mean age of 47 years. None had polycythaemia. Cerebellar locations accounted for 79 % of ISHs, and brainstem ISH with involvement of the floor of the fourth ventricle represented 11 % of ISHs. At last follow-up, two patients harbouring solid medulla oblongata haemangioblastoma had died following severe bulbar syndrome and five patients had died of unrelated causes. One patient had multiple surgeries for three recurrences. Tumoral control was achieved in all cases at last follow-up. Results of the SF-36 questionnaire were as follows: median physical functioning score 100 (range 0-100), median physical problems score 100 (range 0-100), median bodily pain score 100 (range 45-100), median social functioning score 100 (range 25-100), median general mental health score 84 (range 40-92), median emotional problems score 100 (range 0-100), median vitality score 70 (range 35-80) and median general health perceptions score 70 (range 35-100). Mean QOL scores were similar to the general healthy population. CONCLUSION Surgery of ISH provides good QOL and tumoral control except for those located in the medulla oblongata. We recommend considering a careful multimodal therapeutic approach, including radiosurgery for these specific locations.

Abstract
BACKGROUND Intramedullary hemangioblastomas are rare benign tumors, occurring sporadically or in von Hippel- Lindau disease. METHODS We describe our local surgical experience with intramedullary hemangioblastomas. Clinical, imaging and surgical data from five consecutive hemangioblastoma cases identified from a series of 59 patients with intramedullary tumors treated between 2003-2009 are reviewed. RESULTS The mean age of the patients was 39.6 years (range 21- 56). All of them were symptomatic and two patients had von Hippel-Lindau disease with associated posterior fossa hemangioblastomas. All tumors were preoperatively diagnosed as hemangioblastomas based on magnetic resonance findings. All patients underwent surgery with complete removal of the tumor in 4 cases and a partial removal in a case with extension towards the anterior part of the cord. Good neurological outcome was noted in four cases while in the fifth, complicated with a significant intraoperative hemorrhage, a fully reversible aggravation of neurological status occurred. CONCLUSIONS Spinal cord hemangioblastomas are surgically curable tumors. Microsurgical complete resection is the standard of care and can be performed with good neurological outcome in most of the cases. Ventral tumor location and important intraoperative bleeding are associated with less optimal outcome.

Abstract
PURPOSE Hemangioblastomas (HGB) are slow growing benign vascular tumors that arise almost always from the cerebellum and the spinal cord. Supratentorial location is extremely rare with approximately 130 cases published to date. We present a case of a sellar hemangioblastoma. CASE REPORT An eleven year-old girl presented with a sellar and suprasellar tumor that seemed to be a macroadenoma. A transsphenoidal approach was attempted but excessive intraoperative bleeding made the resection not feasible. A second transcranial approach was successful in partially removing the lesion and decompressing the optic chiasm and the pituitary stalk. Pathological review revealed a seller hemangioblastoma. screening for Von Hippel Lindeau Syndrome was negative. CONCLUSION The preoperative diagnosis of HGB is extremely difficult in this case but would have been essential in order to choose the right surgical approach.

Abstract
PURPOSE Standard treatment of asymptomatic spinal cord hemangioblastoma in von Hippel-Lindau (VHL) disease has yet to be established. The purpose of this study was to propose guidelines for the treatment of asymptomatic spinal cord hemangioblastomas in VHL disease. MATERIALS AND METHODS VHL disease patients treated for spinal cord hemangioblastomas between 1999 and 2009 were included. All spinal cord hemangioblastomas were divided into three groups: Group 1, asymptomatic tumors at initial diagnosis followed with serial imaging studies; Group 2, asymptomatic tumors at initial diagnosis that were subsequently resected; and Group 3, symptomatic tumors at initial diagnosis, all of which were resected. RESULTS We identified 24 spinal cord hemangioblastomas in 12 patients. Groups 1, 2 and 3 comprised 13, 4 and 7 tumors, respectively. Group 1 exhibited a smaller tumor volume (257.1 mm³) and syrinx size (0.8 vertebral columns) than those of Group 2 (1304.5 mm³, 3.3 vertebral columns) and Group 3 (1787.4 mm³, 6.1 vertebral columns). No difference in tumor volume or syrinx size was observed between Groups 2 and 3. Five tumors in Group 1 were resected during follow-up because symptoms had developed or the tumor had significantly grown. Finally, among 17 asymptomatic tumors at the initial diagnosis, nine tumors were resected. Only one tumor of these nine tumors resulted in neurological deficits, while five of seven symptomatic tumors caused neurological deficits. CONCLUSION Selective resection of asymptomatic tumors before they cause neurological deficits might bring about better outcomes.

Abstract
PURPOSE Adrenal haemangioblastoma presenting clinically as pheochromocytoma is a rare manifestation of extraneural haemangioblastoma. We present an unusual case of von Hippel-Lindau (VHL) disease that had adrenal and cerebellar haemangioblastoma with multiple renal cysts, and a review of the literature. METHODS Unlike the usual manifestations of secondary polycythemia or increased intracranial pressure and hydrocephalus due to cerebellar lesion, this 36-year-old male presented with hypertension. Investigations revealed right suprarenal mass with raised urinary catecholamines and serum vanillylmandelic acid (VMA) levels, apparently confirming the clinical diagnosis of phaeochromocytoma. RESULTS Histopathology of the biopsy specimen showed features of haemangioblastoma, which was confirmed by immunohistochemistry using antibodies to neuron specific enolase and aquaporin-1. Based on this, the patient was screened for possible features of VHL, which revealed cerebellar haemangioblastoma and multiple renal cysts with angiomatous lesion. Postoperative follow-up showed normal levels of catecholamines without any symptoms of phaeochromocytoma. CONCLUSIONS Adrenal haemangioblastoma is a rare entity with only four cases reported in the literature. Surgical removal is the treatment of choice. However, screening for other possible features of VHL, even in the absence of clinical features, is essential to exclude other potential lesions.

Abstract
OBJECTIVE To investigate the treatment of solid haemangioblastomas in the dorsal medulla oblongata using microneurosurgery in combination with endovascular embolisation. METHODS Clinical data from 11 patients with solid haemangioblastomas in the dorsal medulla oblongata who were treated with endovascular embolisation followed by microneurosurgery were analysed retrospectively. Clinical results were evaluated using the modified Rankin scale. The patients were preoperatively evaluated by neuroimaging methods such as magnetic resonance imaging (MRI), contrast MRI and digital subtraction angiography (DSA). General anaesthesia was induced, the patients were tracheally intubated, and the abnormal vessels were embolised. Surgery to resect the haemangioblastoma was conducted after the blood-clotting index returned to normal levels (generally one month after the interventional treatment). RESULTS Embolisation was accomplished in all 11 patients. DSA analysis revealed that most of the tumour vessels and tumour stains disappeared without any complications. The haemangioblastomas were completely resected. None of the patients received blood transfusion or died during surgery. The neurological deficit was reduced or eliminated in 10 patients, but 1 patient died after experiencing an acute myocardial infarction on the tenth postoperative day. No recurrence occurred during follow-up in patients who underwent total tumour resection. Postoperative grades using the modified Rankin scale were improved in all 10 patients. However, several complications occurred, including communicating hydrocephalus, incision infection, pneumonia and cerebrospinal fluid leakage from the incision. Notably, normal perfusion pressure breakthrough (NPPB) did not develop during or after endovascular embolisation or surgery. CONCLUSION Preoperative endovascular embolisation is a safe and effective adjunct treatment. Employing this treatment, solid haemangioblastomas in the dorsal medulla oblongata can be safely and completely resected.

Abstract
We reported an extremely rare case of cerebellar hemangioblastoma with marked pleomorphism and reviewed the literature. A 68-year-old male presented with a one-month history of headache and vomiting. Neurological examination revealed right-sided dysmetria and truncal ataxia. Contrast-enhanced T1-weighted MR imaging revealed a heterogeneously enhancing tumor with solid and cystic components in the right cerebellum. The solid portion of the tumor was low intensity on diffusion-weighted imaging and low intensity on susceptibility-weighted imaging. 18F-fluorodeoxyglucose PET showed low uptake in the cerebellar tumor and the whole body examination was negative for malignancy. Vertebral angiogram demonstrated moderate tumor staining and no early filling veins. The patient underwent total removal of the tumor through suboccipital craniotomy. Microscopically, the solid tumor contained a cellular rich component consisting of stromal cells and a markedly pleomorphic component including atypical and multinucleated giant cells. The MIB-1 positive rate was 8.2%, which was slightly higher compared to that of hemangioblastomas. We observed strong staining for inhibin-α, aquaporin 1 and neuron specific enolase (NSE) in the tumor cells. PAX-2, cytokeratin and epithelial membrane antigen (EMA) were completely negative in the tumor cells, whereas the tumor cells demonstrated focal staining for CD10. The histological diagnosis was hemangioblastoma. Follow-up MR images showed no evidence of recurrent tumor 14 months after the resection. The study using a combination of immunohistochemical markers (e.g. inhibin-α, aquaporin 1 and PAX-2) is useful for differential diagnosis of hemangioblastoma from metastatic renal cell carcinoma.

Abstract
The aim of this study was to retrospectively evaluate the effectiveness of the Stryker Leibinger neuronavigation system in surgical resection of hemangioblastomas of the posterior fossa. The study included 16 cases of solid hemangioblastoma of posterior cranial fossa treated since we began using Stryker Leibinger neuronavigation system-assisted microneurosurgery in 2003. These cases were compared on the basis of time, blood loss, and complications to 19 similar cases of solid hemangioblastoma that underwent conventional microneurosurgical resection prior to 2003. All patients in the experimental (neuronavigation-assisted) group underwent surgical resection without complications while the control groups' resections all involved blood loss related to the longer operation time. Neuronavigation also resulted in a clear field of surgical vision and clear lesion boundaries, making it easier to remove lesions and reduce accidental injury of adjacent normal structures. The application of navigation technology is very valuable for solid hemangioblastoma operations not only by shortening operative time, thereby significantly reducing operative blood loss, but also by making surgical excision easier, reducing damage to adjacent normal structures, and decreasing surgical complications and mortality.

Abstract
Hemangioblastoma in the medulla oblongata is a relatively rare tumor. We present the case of a giant hemangioblastoma occurring in the dorsal medulla oblongata. A 33-year-old man with no neurological symptoms was diagnosed with a hemangioblastoma in the dorsal medulla oblongata, and opted for observation in the outpatient department. After 22 months of observation time, MRI scans showed rapid local tumor progression and obstructive hydrocephalus. At this point, he presented with mild dysphagia as a preoperative neurological deficit. Total surgical removal of the tumor was performed after temporary ventricle drainage and preoperative embolization of the feeding artery. Postoperatively, he became fully conscious but developed bulbar palsy followed by tracheostomy. During the 12 months of postoperative follow-up, severe dysphagia was still present.

Abstract
We performed 3D-CT angiography (3D-CTA) with contrast injection to a feeding artery through a selectively introduced catheter into the intercostal artery in a patient with spinal hemangioblastoma. It revealed a relative three-dimensional (3D) anatomy between a tumor body, feeding arteries, draining veins, and surrounding vertebrae with superior resolution to 3D-CTA with intravenous contrast injection. This observation was used for preoperative planning facilitating tumor removal, through reconstructed 3D fly-through animation providing intraoperative identification and obliteration of feeding arteries. This examination was carried out without difficulty by utilizing IVR-CT/angio system (IVR: interventional radiology) which combines angiographic and CT equipment with a single fluoroscopy table, because it does not require a room-to-room transfer of the patient with the catheter left cannulated. DSA detection for any spinal lesions, neoplastic or vascular ones, is always better assisted by 3D-CTA with the IVR-CT/angio system (IVR-CTA).

Abstract
A 33-year-old male presented with a headache. He had a history of a previous surgical procedure for excisions of cervical spine hemangioblastomas 13 years prior He had a family history of von-Hippel Lindau (VHL) disease, and a VHL mutation was identified. Brain magnetic resonance imaging showed enhanced mass lesions in both the third and right lateral ventricles as well as in the cerebellum. The lesion in the right lateral ventricle also had a cystic component. Two-staged resections of the tumors in the third and right lateral ventricles and ventriculo-peritoneal shunt were performed. A histopathological specimen was compatible with a hemangioblastoma. Supratentorial intraventricular hemangioblastomas are extremely rare. We reviewed the literature and discussed the features.

Abstract
Intradural spinal tumors are classified in extra- and intramedullary tumors. The most frequent intradural-extramedullary tumors are meningiomas and neurinomas. Among the intradural-intramedullary tumors the most frequent ones are ependymomas and astrocytomas. Independent of their origin, spinal tumors usually manifest with progressive local or radicular pain and neurological deficits. The treatment of choice for most of these tumors is a complete surgical resection. In tumors with infiltrative growth into the intramedullary area, a marginal tumor tissue has to be left in situ in order to avoid additional neurological deficits. In particular if neurological deficits appear, a fast surgical intervention is indicated, since the prognosis depends on duration and severity of the preoperative existing deficits. Below, clinical presentation and relevant treatment options of spinal intradural tumors are discussed.

Abstract
A clinical example shows that after a neurosurgical operation in posterior fossa there could appear intracranial pressure difference between supra- and infratentorial spaces. This difference develops due to pressure rise in posterior fossa and maintenance of this hypertension postoperatively. Hypertension in posterior fossa and intracranial difference are accompanied by brainstem reactions and temporary neurological disorders. While the pressure difference decreases and ICP in posterior fossa normalizes the neurological symptoms disappear. ICP in supratentorial space not necessarily correlates with ICP in infratentorial space. In some cases it is necessary to measure ICP in infratentorial space after posterior fossa surgery.

Abstract
OBJECTIVE to study the clinicopathological features, imaging characteristics, immunophenotypes and differential diagnosis of giant cell angioblastoma (GCAB). METHODS a case of GCAB in the left middle-upper tibia and fibula was studied by light microscopy, X-ray and CT imaging, immunohistochemistry. RESULTS X-ray and CT imaging showed a clearer lesion in the left middle-upper tibia than in the ipsilateral fibula with enlarged ostealleosis and increased inhomogeneously medullary cavity density, irregular thickening of cortical bone, local cortical default at the inner edge, soft tissue swelling around the abnormal bone. Histologically, tumor tissue was located between the bone trabeculae by nodular, linear and plexiform aggregates of oval-to-spindle cells, large mononucleate cells and multinucleate giant cells with prominent nucleoli and abundant granular eosinophilic cytoplasm. Some aggregates had uncentain amount of discernible lumens, either empty or containing few erythrocytes. A concentric arrangement of oval-to-spindle Cells around small-caliber vascular structures together with collagen fiber contributed to a so-called 'onion-skin' arrangement. The background showed a loose mesenchymal stroma formed of some inconspicuous spindle-fibroblast-like cells, stellate-shape mesenchymal cells, a moderate mononuclear inflammatory cell infiltrate and scattered mast cells. Immunophenotype showed the tumor cells and giant cells strongly positive for vimentin. A good many oval-to-spindle cells stained markedly for CD31 and CD34, but weakly for FVIII, while the giant cells are highlighted instead by CD68, occasionally, very few giant cells showed positive focally for FVIII, a-SMA decorated notedly the cells surrounding the endothelium-like cells but weakly positive in some other tumor cells. CONCLUSION GCAB is a rare, locally infiltrative but slow growing neoplastic angiogenesis with unique morphological characteristics during infancy, which may occur not only in the skin, mucosa, subcutis and deep soft tissue but also in the bone.

Abstract
PURPOSE The purpose of this study was to evaluate the outcome of surgical treatment of hemangioblastomas in the medulla oblongata. METHODS Between January 2006 and December 2007, 18 patients who underwent surgery for hemangioblastomas in the medulla oblongata in the Neurosurgical Department of Huashan Hospital were retrospectively reviewed. RESULT The study population was 13 males and five females. The main symptoms were headache, cervical pain, and dizziness. All patients had preoperative and postoperative examination by MRI. There were five cystic tumors and 13 solid tumors. Tumor diameter ranged from 1 to 4.3 cm (mean, 2.6 cm). Complete tumor resection was achieved in all patients, but one patient died. Embolization was done in three patients. According to McCormick scale, postoperative condition was worse in one patient, unchanged in 14 patients, and improved in three patients. In follow-up assessments, no surviving patients remained in a worse condition. Compared with the preoperative condition, 11 patients were unchanged, and six patients exhibited improvement. Tumor recurrence was not observed during follow-up. CONCLUSION Surgery is the first-line treatment for symptomatic patients with hemangioblastomas in the medulla oblongata. Good results can be achieved for the cystic or small solid tumors. Large solid tumors remain a surgical challenge due to arteriovenous malformation-like vascularization. Preoperative embolization is useful for large solid tumors. For asymptomatic tumors, careful long-term observation or radiosurgery could be chosen.

Abstract
Von Hippel-Lindau disease is a dominant autosomal genetic condition with variable penetrance and expressivity. It is characterized by hemangioblastomas in multiple organs but mainly in the retina and cerebellum. There is a predisposition to carcinoma. We report a cesarean section in a 28-year-old woman with von Hippel-Lindau disease. She had no neurologic symptoms at the time of the operation but a history of ocular and cerebellar involvement and several procedures to remove cerebellar hemangioblastomas. Epidural anesthesia was chosen given that there was no nervous system involvement at the time of surgery.

Abstract
OBJECTIVE To study clinicopathologic features, diagnosis, treatment and prognosis of von Hippel-Lindau (VHL) syndrome-related and sporadic hemangioblastomas of the central nervous system (CNS-HB). METHODS Histopathological, ultrastructural, immunohistochemical (EnVision method) and clinical features of 21 VHL syndrome and 63 sporadic CNS-HB cases were studied with correlation of the available follow-up information. RESULTS Twenty-one VHL patients accompanied with a total of 87 CNS-HBs, including one patient of developing 12 HBs within 13 years. There were 10 patients presenting other lesions related to VHL, including 6 retinal HBs, 4 pancreatic tumors (endocrine tumor and microcystic cystadenoma), 1 clear renal cell carcinoma, 4 renal cysts and 1 endolymphatic sac tumor. One patient developed 5 different tumors related to VHL within a period of 4 years. In the 63 cases of sporadic CNS-HB (34 male and 29 female), the mean age was 43.0 years. Among the 18 VHL syndrome patients with available follow-up information, 14 were still alive and within them, 4 became disabled and 11 had developed new lesions. The other 4 patients died. Among the 42 patients of sporadic HB with follow-up information, 39 were alive including 3 disabled cases, and the other 3 died. Histologically, the tumors showed large and vacuolated stromal cells. Some tumors showed atypical nuclei. Involvement of the brain tissue was seen in 32 cases, among which, 21 patients with available follow-up information were learnt to be alive. Tumor cells of HB stained positive for vimentin, EGFR, Inhibin alpha and D2-40, but negative for CD34 and CD68. In 3 cases of HB, some stromal cells were positive for GFAP. All cases showed a low expression for Ki-67, except 2 cases with 2% and 1 case with 5% Ki-67 indices. CONCLUSIONS VHL syndrome is a multisystem disorder with a poor prognosis and a high rate of missed diagnosis. The syndrome is characterized by development of various benign and malignant tumors. The most common tumor is CNS-HB, which occurs predominantly in the cerebellum. Patients with VHL syndrome tend to present at a younger age than patients with sporadic CNS-HBs, and VHL related HB occurs more predominantly in the brain stem and spinal cord. Prognosis of CNS-HB patients is not correlated with the nuclear atypicality, expression for Ki-67 and involvement of the brain tissue. Because new lesions may develop during the patient's lifetime. So that, regular clinical inspection is recommended in order to check up the development of any new lesions.

Abstract
BACKGROUND In the context of von Hippel-Lindau disease (VHL), the medulla oblongata is a relatively frequent site of growth of hemangioblastomas, posing related clinical and surgical difficulties. Their management requires a close correlation between clinical evolution and morphological surveillance. In order to describe their clinical and surgical features, we reviewed our experience in the treatment of these lesions. METHODS Between 2001 and 2009, 14 patients (9 female and 5 male, mean age 34 years) underwent removal of 15 lower brain stem hemangioblastomas. Based on the review of the clinical records and outpatient long-term follow-up visits, their clinical course was analyzed. Functional evaluation was measured with the Karnofsky Performance Scale (KPS) on admission, at discharge and at the last follow-up. The mean follow-up period was 30.8 months (range 4-99). RESULTS All the operated hemangioblastomas were located in the dorsal medulla oblongata, in the context of multiple lesions, cerebellar and/or spinal. In ten patients hemangioblastomas were located in a median position at the obex area; in four cases a lateral location was observed. Cystic component was absent in two cases. Clinical onset preceded surgery by a mean of 8.5 months. Preoperatively three patients showed a KPS lower than 80, ten patients between 80 and 90, and one patient scored 100 (asymptomatic). There was no surgical mortality. Nine out of 14 patients showed a temporary surgical morbidity. One patient required a tracheostomy. At follow-up ten patients scored a KPS better than before the operation, while the other four patients remained stable. Permanent morbidity was observed in three patients. CONCLUSIONS Lower brain stem hemangioblastomas in the context of VHL show an often gradual onset of signs and symptoms except for patients who develop an obstructive hydrocephalus. Although transient surgical complications are possible, surgery provides favorable long-term results.

Abstract
Acute lung injury (ALI), including acute respiratory distress syndrome (ARDS), is a critical condition consisting of acute hypoxaemic respiratory failure with bilateral pulmonary infiltrates of non-cardiogenic origin. Occasionally it develops in patients with acute or subacute central nervous system pathologies, such as increased intracranial pressure and brain stem lesions. The exact epidemiology of neurogenic pulmonary oedema is unknown. However, due to non-specific clinical manifestation it often remains undiagnosed. Its pathogenesis probably involves overactivation of the sympathetic autonomic system with pulmonary hypertension and increased vessel permeability. We present a case of successfully managed ARDS in a previously healthy patient with newly diagnosed and symptomatic haemangioblastoma of the medulla oblongata. In this context we also review current knowledge on the aetiopathogenesis, diagnostic criteria and treatment for neurogenic ARDS.
