[PMID: 36980542 PMCID: PMC10046302 DOI: 10.3390/cancers15061657] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 02/28/2023] [Accepted: 03/05/2023] [Indexed: 03/30/2023] Open
Abstract
Von Hippel-Lindau (VHL) disease diagnosis is based on two criteria sets: International criteria (IC, two hemangioblastomas, one hemangioblastoma plus one visceral lesion, or VHL family history/pathogenic variant plus hemangioblastoma/visceral lesion); or Danish criteria (DC, two clinical manifestations, or VHL family history/pathogenic variant plus hemangioblastoma/visceral lesion). We aimed to compare the characteristics of patients with VHL-related pancreatic neuroendocrine tumor (vPNET) meeting either the clinical Danish criteria only (DOC) or IC to those with sporadic PNET (sPNET). The cohort included 33 patients with VHL (20 vPNETs) and 65 with sPNET. In terms of genetic testing and family history of VHL, 90.0% of the patients with vPNET in the IC group had a germline VHL pathogenic variant, and 70.0% had a family history of VHL vs. 20% and 10% in the DOC group, respectively (p < 0.05 for both). Patients with vPNET were younger at diagnosis compared with sPNET (51.6 ± 4.1 vs. 62.8 ± 1.5 years, p < 0.05). Patients in the IC group were younger at diagnosis with VHL, vPNET, pheochromocytoma, or paraganglioma (PPGL) and renal-cell carcinoma (RCC) than those in the DOC group (p < 0.05 for all comparisons). The most prevalent presenting manifestations were hemangioblastoma (42.8%) and PPGL (33.3%) vs. RCC (58.3%) and PNET (41.7%) in the IC vs. DOC groups. In conclusion, patients with vPNET meeting DOC criteria show greater similarity to sPNET. We suggest performing genetic testing, rather than solely using clinical criteria, for establishing the diagnosis of VHL.

Abstract
Background Supratentorial hemangioblastoma is an extremely rare neoplasm. The aim of this study is to delineate the clinical features among cystic and solid supratentorial hemangioblastoma patients and evaluate the risk factors for progression-free survival (PFS). Methods We conducted a literature search in PubMed for histopathologically identified supratentorial hemangioblastoma between 1947 and 2021 and extracted and collected the clinical features of patients treated at our own institute. The rate of PFS was determined using Kaplan-Meier analysis. Differences in categorical factors, such as the location of tumor and diagnosis of von Hippel-Lindau disease, were analyzed using the Pearson χ 2 test. A Cox regression analysis was performed to evaluate the association between various variates and survival outcomes. Results A total of 237 cases of supratentorial hemangioblastoma were identified from 169 studies. A survival analysis found that patients with cystic tumors had a significantly better prognosis than those with solid tumors (log-rank, p = 0.0122). Cox regression analysis suggested that cystic hemangioblastoma (hazard ratio (HR): 0.186, 95% CI: 0.043-0.803, p < 0.05) and gross total resection (GTR) (HR: 0.126, 95% CI: 0.049-0.323, p < 0.001) were significant predictors of longer survival (PFS) for supratentorial hemangioblastoma. Following an analysis of 13 supratentorial hemangioblastoma cases from our institute, we validated that cystic tumor had improved prognosis than solid tumor (log-rank, p = 0.0096) and GTR was superior to subtotal resection (log-rank, p = 0.0029). Conclusions Cystic hemangioblastoma vs. solid hemangioblastoma may be two tumoral statuses with different clinical features, and a specific treatment strategy should be considered.

Abstract
Von Hippel-Lindau (VHL) is a multi-system disease which results in significant morbidity from central nervous system (CNS) involvement as well as ocular, renal and neuro-endocrine effects. Haemangioblastomas of the CNS present a number of challenges. The natural history of these lesions is varied, as is the size and location within the CNS. Whilst surgery is considered the mainstay of treatment and best chance at curing these lesions, this is also often associated with significant risks due to the anatomical location of these lesions, most commonly the posterior fossa and spinal cord.We review the literature and describe our experience across two separate European VHL referral centres. Alternative treatment options and combined modalities are increasingly being used in the context of managing CNS haemangioblastomas. We analyse the increasing use of stereotactic radiosurgery and the evolution of medical treatments as potential future adjuncts to surgery. The availability of multiple modalities in our armamentarium is essential in tailoring a personalised treatment approach to these patients. Owing to the multi-systemic nature of the disease, in our experience, managing the care of patients with VHL is best delivered using an interdisciplinary approach utilising multiple specialties and adopting an individually tailored holistic approach.

Abstract
PURPOSE OF REVIEW To provide an overview of diagnosis, genetic abnormalities, clinical signs and treatment options for the major heritable renal cell carcinoma (RCC) syndromes. RECENT FINDINGS RCC in major hereditary syndromes are disorders which are typically autosomal dominant. They predispose patients to early onset of RCC and may exhibit other extrarenal manifestations. Early recognition of these diseases allows correct screening at appropriate ages as well as early detection of RCC. Moreover, expedient identification may optimize the management of extra renal manifestations as well as allow for genetic testing and screening of at-risk relatives. SUMMARY The risk of RCC in these major heritable syndromes is higher than sporadic disease. They occur at earlier age groups and can be multifocal or bilateral. Tumours are observed until at least 3 cm before any intervention, while nephron sparing surgery is widely considered as the treatment of choice except for hereditary leiomyomatosis with renal cell cancer, of which radical nephrectomy is treatment of choice. Intervention should be timeous as there is a highly reported incidence of early metastasis. Molecular therapies have been used in the setting of patients with metastasis, some of which show favourable outcomes.

Abstract
The prognostic factors for surgically removed spinal hemangioblastomas, the impact of VHL disease on outcome, and the role of intraoperative neuromonitoring are still not completely clear. The aim of this study was to review our experience with spinal hemangioblastomas in order to assess potential predictors of neurological outcome after surgery. All cases of spinal hemangioblastomas removed at two Italian academic institutions from 1985 to 2020 were reviewed. Data about clinical presentation and symptom duration, diagnosis of VHL, surgical approach, use of IONM, duration of hospital stay, follow-up, and modified McCormick grade before and after surgery were extracted. Sixty-one patients (31 F, 30 M) underwent 69 surgeries to remove 74 spinal hemangioblastomas (37 cervical, 32 thoracic, 5 lumbar). Improvement was found in 32.3% of cases, neurological condition remained stable in 51.6% of cases, and deteriorated in 16.1% of patients. A worsening trend in VHL patients and an improvement trend in non-VHL patients were detected, despite the lack of statistical significance. Laminotomy and use of IONM were found to be associated with better outcome, although no association was found between surgery without IONM and worse outcome. In most cases, patients affected by spinal hemangioblastomas can expect a good long-term outcome. In our experience, laminotomy seems to be associated with better outcome compared to laminectomy. While its absence is not associated with worse outcome, IONM seems to be associated with a better neurological outcome. Our study suggests that the more impaired the preoperative neurological condition, the worse the outcome.

Abstract
BACKGROUND Hemangioblastomas (HBs) are well-vascularized, benign central nervous system tumors and the third most common primary spinal cord tumor after astrocytoma/ependymoma, occurring sporadically or as a part of autosomal dominant von Hippel-Lindau disease, in which tumors are often multiple and prone to relapse. Spinal HBs are commonly located in the cervical cord and associated with a syrinx formation. Owing to location and growth trends, they may cause significant neurological deficit, impairing quality of life. We conducted a systematic review to understand better clinical insights into spinal HB in adults and compare spinal HB versus posterior cranial fossa HB. METHODS Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for conducting systematic reviews, we reviewed the English-language literature on adult spinal HB in the MEDLINE/PubMed database over the last 40 years. RESULTS We reviewed 237 articles on adult spinal HB and analyzed national and continental distribution, clinical symptoms, tumor location and presence of syringomyelia, treatment strategies and postoperative complications, histology and immunochemistry, and treatment outcomes. We compared individual characteristics in sporadic and von Hippel-Lindau disease spinal HBs. Finally, we compared features of posterior cranial fossa and spinal HBs. CONCLUSIONS Spinal cord HBs most commonly have a dorsal intramedullary location. Total surgical tumor resection is the first treatment option; preoperative embolization may be performed to reduce intraoperative bleeding and surgical time. HBs located in the spine have decreased mortality and rate of infection, but increased rates of cardiopulmonary complications compared with HBs in the posterior cranial fossa.

Case report: a synonymous VHL mutation (c.414A > G, p.Pro138Pro) causes pathogenic familial hemangioblastoma through dysregulated splicing. BMC MEDICAL GENETICS 2020; 21:42. [PMID: 32106822 PMCID: PMC7045488 DOI: 10.1186/s12881-020-0976-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Accepted: 02/17/2020] [Indexed: 11/10/2022]
Abstract
Background von Hippel-Lindau (VHL) disease is a familial neoplasia syndrome that results from the germline mutation of VHL. Pathogenic VHL mutations include deletion, frameshift, nonsense and missense mutations. Synonymous mutations are expected to be phenotypically silent and their role in VHL disease remains poorly understood. Case presentation We report a Caucasian male with a family history of pheochromocytoma and the synonymous VHL mutation c.414A > G (p.Pro138Pro). At 47-years, MRI revealed pheochromocytoma in the left adrenal gland and hemangioblastomas in the spine and brain. Pheochromocytoma was treated by adrenalectomy. Radiotherapy, followed by craniotomy and resection were needed to reduce hemangioblastomas to residual lesions. Two of three of the proband’s children inherited the mutation and both presented with retinal hemangioblastomas without pheochromocytoma at age 7: one twin needed four laser treatments. Primary skin fibroblasts carrying the heterozygous mutation or wild type VHL were established from the family. Mutant fibroblasts downregulated full-length VHL mRNA and protein, and upregulated the short VHL mRNA isoform (a result of exon 2 skipping in splicing) at the mRNA level but not at the protein level. Conclusions Our study shows that the synonymous VHL mutation c.414A > G can within 7 years induce pediatric retinal hemangioblastoma in absence of pheochromocytoma. This highlights the need to include splicing-altering synonymous mutations into the screening for VHL disease. This is also the first report on detecting and validating a synonymous VHL mutation using patient-derived fibroblasts. The mutation c.414A > G translates to p.Pro138Pro, yet it is not functionally silent, because it causes aberrant splicing by skipping exon 2. The reduced but not completely abolished pVHL protein in a loss-of-heterozygosity genetic backdrop may underlie the etiology of VHL disease.

Abstract
Astrocytic gliomas are the most common and lethal form of intracranial tumors. These tumors are characterized by a significant heterogeneity in terms of cytopathological, transcriptional, and (epi)genomic features. This heterogeneity has made these cancers one of the most challenging types of cancers to study and treat. To uncover these complexities and to have better understanding of the disease initiation and progression, identification, and characterization of underlying cellular and molecular pathways related to (epi)genetics of astrocytic gliomas is crucial. Here, we discuss and summarize molecular and (epi)genetic mechanisms that provide clues as to the pathogenesis of astrocytic gliomas.

Abstract
BACKGROUND Historically, von Hippel-Lindau (VHL) disease is characterised by a poor survival. Although genotype-phenotype correlation has been described in many studies, the risk factors for VHL survival remain unclear. This study aims to evaluate the median survival of Chinese patients with VHL disease and explore whether VHL survival is influenced by genetic and clinical factors. METHODS In this retrospective study, we recruited 340 patients from 127 VHL families. Kaplan-Meier plot and Cox regression model were used to evaluate the median survival and assess how survival was influenced by birth year, birth order, sex, family history, mutation type, onset age and first presenting symptom. RESULTS The estimated median life expectancy for Chinese patients with VHL disease was 62 years. Patients with early-onset age, positive family history and truncating mutation types had poorer overall and VHL-related survival. Patients with haemangioblastoma as their first presenting symptom were related to a higher risk of death from central nervous system haemangioblastoma than those with abdominal lesions (HR 8.84, 95% CI 2.04 to 38.37, P=0.004). CONCLUSIONS This largest VHL survival analysis indicates that onset age, family history, mutation type and first presenting symptom have an effect on the survival of patients with VHL disease, which is helpful to genetic counselling and clinical decision-making.

Abstract
The Von Hippel-Lindau (VHL) disease is an autosomal dominant disorder characterized by the predisposition for multiple tumors caused by germline mutations in the tumor suppressor gene VHL. This disease is associated with a high morbidity and mortality and presents a variable expression, with different phenotypes from family to family, affecting different organs during the lifetime. The main manifestations of VHL are hemangioblastomas of the central nervous system and retina, renal carcinomas and cysts, bilateral pheochromocytomas, cystic and solid tumors of the pancreas, cystadenomas of the epididymis, and endolymphatic sac tumors. The discovery of any of the syndrome components should raise suspicion of this disease and other stigmas must then be investigated. Due to the complexities associated with management of the various VHL manifestation, the diagnosis and the follow-up of this syndrome is a challenge in the clinical practice and a multidisciplinary approach is needed. The particular relevance to endocrinologists is the detection of pheochromocytomas in 35% and islet cell tumors in 17% of VHL patients, which can be associated with hypertension, hypoglycemia, cardiac arrhythmias, and carcinoid syndrome. The purpose of this review is to define the Von Hippel-Lindau syndrome addressing its clinical aspects and classification, the importance of genetic counseling and to propose a protocol for clinical follow-up.

Hypoxia inducible factor (HIF) in the tumor microenvironment: friend or foe? SCIENCE CHINA-LIFE SCIENCES 2017; 60:1114-1124.

Abstract
Hypoxia acts as an important regulator of physiological and pathological processes. Hypoxia inducible factors (HIFs) are the central players involved in the cellular adaptation to hypoxia and are regulated by oxygen sensing EGLN prolyl hydroxylases. Hypoxia affects many aspects of cellular growth through both redox effects and through the stabilization of HIFs. The HIF isoforms likely have differential effects on tumor growth via alteration of metabolism, growth, and self-renewal and are likely highly context-dependent. In some tumors such as renal cell carcinoma, the EGLN/HIF axis appears to drive tumorigenesis, while in many others HIF1 and HIF2 may actually have a tumor suppressive role. An emerging role of HIF biology is its effects on the tumor microenvironment. The EGLN/HIF axis plays a key role in regulating the function of the various components of the tumor microenvironment, which include cancer-associated fibroblasts, endothelial cells, immune cells, and the extracellular matrix (ECM). Here, we discuss hypoxia and the diverse roles of HIFs in the setting of tumorigenesis and the maintenance of the tumor microenvironment as well as possible future directions of the field.

Abstract
Hemangioblastomas are rare and benign tumors accounting for less than 2% of all central nervous system (CNS) tumors. The vast majority of hemangioblastomas occur sporadically, whereas a small number of cases, especially in younger patients, are associated with Von Hippel–Lindau (VHL) syndrome. It is thought that loss of tumor suppressor function of the VHL gene results in stabilization of hypoxia-inducible factor alpha with downstream activation of cellular proliferative and angiogenic genes that promote tumorigenesis. VHL-related hemangioblastomas predominantly occur in the cerebellum and spine. Lesions are often diagnosed on contrast-enhanced craniospinal MRIs, and the diagnosis of VHL occurs through assessment for germline VHL mutations. Surgical resection remains the primary treatment modality for symptomatic or worrisome lesions, with excellent local control rates and neurological outcomes. Stereotactic radiotherapy can be employed in patients who are deemed high risk for surgery, have multiple lesions, or have non-resectable lesions. Given the tendency for development of either new or multiple lesions, close radiographic surveillance is often recommended for asymptomatic lesions.

Abstract
Study Design Retrospective cohort study. Purpose To examine the clinical profile and surgical complications in patients with spinal hemangioblastomas and to evaluate the long-term outcome in them. Overview of Literature Although considered to be histologically benign, hemangioblastomas may cause significant neurological deficits. The proportion of spinal hemangioblastomas associated with von Hippel–Lindau (VHL) disease has been estimated be 13%–59%. Preoperative neurological function correlates with postoperative neurological status. Studies have shown no difference in outcomes between sporadic and VHL-associated spinal hemangioblastomas. Methods This retrospective study included 14 consecutive patients treated for spinal hemangioblastomas at our institute between January 2000 and June 2013. The mean follow-up period was 5 years. Magnetic resonance imaging of the complete neuraxis was performed in all cases, and preoperative embolization was performed in two cases. Results In total, 14 patients underwent 18 surgeries, of which 15 were for spinal hemangioblastomas. Of all the patients, 86% had motor weakness and 79% presented with sensory disturbances. Preoperative McCormick functional grades were grade I in 7 (50%), grade II in 3 (21%), and grade III in 4 (29%) patients; 50% patients were diagnosed with VHL disease. All patients underwent complete resection of the tumor. Eight patients experienced deterioration in their neurological status in the immediate postoperative period; among them, five had gradual improvement. At 5-year follow-up, 11 (78.57%) patients showed good functional outcomes. Conclusions Microsurgical excision of spinal hemangioblastomas can cause postoperative morbidity, mainly in the form of neurological deterioration. Almost half of our patients had deterioration in the McCormick grade in the immediate postoperative period. However, a complete microsurgical excision can result in good long-term functional outcomes, as most of the immediate postoperative neurological deterioration in our patients was reversible. There was no difference in the long-term functional outcomes between sporadic and VHL-associated spinal hemangioblastomas.

Abstract
Haemangioblastoma is a rare malignancy of the CNS where vascular proliferation causes lesions due to endothelial propagation. We found that conditionally expressing mutant Kras, using Rag1-Cre, gave rise to CNS haemangioblastoma in the cortex and cerebellum in mice that present with highly vascular tumours with stromal cells similar to human haemangioblastomas. The aberrant haemangioblastoma endothelial cells do not express mutant Kras but rather the mutant oncogene is expressed in CNS interstitial cells, including neuronal cells and progeny. This demonstrates a non-cell autonomous origin of this disease that is unexpectedly induced via Rag1-Cre expression in CNS interstitial cells. This is the first time that mutant RAS has been shown to stimulate non-cell autonomous proliferation in malignancy and suggests that mutant RAS can control endothelial cell proliferation in neo-vascularisation when expressed in certain cells.

Abstract
La Neuroradiologia moderna ha profondamente modificato lo studio delle facomatosi del sistema nervoso. La radiologia convenzionale mantiene qualche indicazione nel bilancio delle lesioni displasiche ossee craniche e rachidee nella neurofibromatosi tipo 1. La tomografia computerizzata è efficace per la ricerca dei neurofibromi dei plessi cervicale e lombosacrale, per la diagnosi della sclerosi tuberosa di Bourneville e dell'angiomatosi encefalo-trigeminale di Sturge-Weber (salvo nel caso d'angioma non calcifico). La risonanza magnetica in TI dopo contrasto è il mezzo più efficace per il bilancio delle lesioni intra-durali della neurofibromatosi di tipo 1 e 2, per la ricerca dei tuberi degenerati della sclerosi tuberosa di Bourneville e per il bilancio della malattia di von Hippel Lindau. La mielografia non mantiene praticamente più indicazioni salvo per la conferma di certi meningoceli di difficile diagnosi, soprattutto nel quadro della neurofibromatosi di tipo 1 associate a delle importanti scoliosi. L'angiografia, diagnostica e terapeutica, è utile nel caso di emangioblastoma.

Abstract
BACKGROUND Historically, the survival of patients with von Hippel-Lindau disease (vHL) has been poorer than that of the general population. We aimed to determine whether the survival of VHL mutation carriers and their risk of vHL-related death has changed over time and how it has been affected by sex, genotype and surveillance attendance. METHODS In a retrospective cohort study, we included all known Danish vHL families with a VHL mutation. We assessed the survival and causes of death for 143 VHL mutation carriers using Cox regression models and compared vHL survival with that of 137 siblings without vHL. vHL life expectancy was compared with the general population using a relative survival model. RESULTS The estimated mean life expectancies for male and female patients born in 2000 were 67 and 60 years, respectively. Survival is influenced by the sex and genotype of the patient. Female patients have a significantly higher risk of vHL-related death than male patients (HR=2.25, 95% CI 1.20 to 4.20, p=0.011). Overall, 79% (53 of 67) of deaths were vHL-related, but the risk of vHL-related death has decreased over time, as has the frequency of renal cell carcinoma (RCC)-related death. Surveillance is especially beneficial for truncating mutation carriers, who have the greatest RCC and central nervous system (CNS) hemangioblastoma risk. CONCLUSIONS vHL survival has improved over time and has become closer to that of siblings without vHL and the general population. Even though the risk of vHL-related death has decreased significantly, the main cause of death is still CNS hemangioblastomas and hence improved treatment options are essential.

Abstract
von Hippel–Lindau disease (VHL) is a familial neoplasia syndrome associated with multisystem tumor development. Depending on tumor type and location, current treatments for VHL-associated tumors can include a combination of chemotherapy, radiation therapy, and/or surgery. Central nervous system (CNS) manifestations of VHL include craniospinal hemangioblastomas and endolymphatic sac tumors (ELSTs). While the first-line treatment for both types of VHL-associated CNS tumors is surgery, the indications for treatment are patient specific and different for each tumor type. Although early sign/symptom formation is the primary indication for resection of craniospinal hemangioblastomas, radiographic discovery (asymptomatic and symptomatic) of ELSTs can be an indication for resection of ELSTs in VHL patients. Recently, research has revealed that specific VHL germline mutations may permit targeted medical treatments of not only CNS manifestations of VHL-associated tumors but also visceral tumors. Specifically, missense mutations can result in the translation of functional VHL protein (pVHL) that is rapidly degraded resulting in functional loss of the pVHL, and inhibitors of pVHL degradation may slow protein degradation and restore pVHL function. Emerging research will investigate the safety and practicality of using potential targeted therapies.

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
Supratentorial hemangioblastomas (HBLs) are rare, benign vascular tumors of the central nervous system neoplasms. Very scarce literature is available regarding supratentorial HBL without von Hippel–Lindau (VHL) syndrome in an adult. We reviewed the literature and PubMed advanced search showed only a few results of supratentorial HBL without VHL syndrome. We reported a rare case of cystic supratentorial HBL in 39-year-old male affecting the parietal lobe without VHL syndrome. Supratentorial HBL is a rare tumor and supratentorial HBL without VHL syndrome are even rarer. Being a rare entity, not much clinical data is currently available regarding supratentorial HBLs, thus necessitating the need for further reporting and review of such cases.

Abstract
This report describes a patient with VHL syndrome and uncontrolled hypertension due to pheochromocytoma who developed obstructive hydrocephalus and underwent craniotomy for the excision of a cerebellar hemangioblastoma combined with a laparoscopic adrenalectomy. A rare case of cerebellar hemangioblastoma excision in a patient with von Hippel–Lindau disease complicated by uncontrolled hypertension due to pheochromocytoma. There is hardly any literature on emergency craniotomy in a patient with von Hippel–Lindau disease. There are no clear treatment guidelines for the emergency excision of cerebellar hemangioblastomas in patients with intracranial hypertension complicated by abnormal hypertension due to pheochromocytoma whose blood pressure is not sufficiently controlled before surgery.
Introduction This report describes a patient with Von Hippel–Lindau (VHL) syndrome and uncontrolled hypertension due to pheochromocytoma who underwent craniotomy for the excision of a cerebellar hemangioblastoma combined with a laparoscopic adrenalectomy. Case report A 31-year-old man presented with severe headache. MRI showed areas of abnormal enhancement in the left cerebellum that were determined to be hemangioblastoma with mass effect and obstructive hydrocephalus. His blood pressure rose abruptly and could not be controlled. CT of the abdomen revealed bilateral suprarenal tumors, and the patient was diagnosed as having VHL syndrome.On the third day, he presented with increasing headache, a decreased level of consciousness, and hemiparesis. We were not able to perform an craniotomy because abdominal compression in the prone or sitting position resulted in severe hypertension. We performed ventricular drainage to control his ICP. On the fifth day, we first performed a bilateral laparoscopic adrenalectomy to control ICP and then moved the patient to the prone position before performing a craniotomy to remove the left cerebellar hemangioblastoma. Discu ssion & conclusion In patients with pheochromocytoma, the effects of catecholamine oversecretion can cause significant perioperative morbidity and mortality, but these can be prevented by appropriate preoperative medical management. When carrying out an excision of cerebellar hemangioblastomas in patients with intracranial hypertension complicated by abnormal hypertension due to pheochromocytoma whose blood pressure is not sufficiently controlled, tumor resection of the pheochromocytoma prior to cerebellar hemangioblastoma excision in the same surgery may prevent increased ICP and reduce perioperative risk.

Abstract
OBJECTIVE Peritumoral cysts are frequently associated with CNS hemangioblastomas and often underlie neurological morbidity and mortality. To determine their natural history and clinical impact, the authors prospectively analyzed hemangioblastoma-associated peritumoral cysts in patients with von Hippel-Lindau (VHL) disease. METHODS Patients with VHL disease who had 2 or more years of follow-up and who were enrolled in a prospective study at the National Institutes of Health were included. Serial prospectively acquired laboratory, genetic, imaging, and clinical data were analyzed. RESULTS One hundred thirty-two patients (of 225 in the VHL study with at least 2 years of follow-up) had peritumoral cysts that were followed for more than 2 years (total of 292 CNS peritumoral cysts). The mean age at study entrance was 37.4 ± 13.1 years ([mean ± SD], median 37.9, range 12.3-65.1 years). The mean follow-up was 7.0 ± 1.7 years (median 7.3, range 2.1-9.0 years). Over the study period, 121 of the 292 peritumoral cysts (41.4%) became symptomatic. Development of new cysts was associated with a larger number cysts at study enrollment (p = 0.002) and younger age (p < 0.0001). Cyst growth rate was associated with anatomical location (cerebellum cysts grew faster than spine and brainstem cysts; p = 0.0002 and p = 0.0008), younger age (< 35 years of age; p = 0.0006), and development of new neurological symptoms (p < 0.0001). Cyst size at symptom production depended on anatomical location (p < 0.0001; largest to smallest were found, successively, in the cerebellum, spinal cord, and brainstem). The most common location for peritumoral cysts was the cerebellum (184 cysts [63%]; p < 0.0001). CONCLUSIONS Peritumoral cysts frequently underlie symptom formation that requires surgical intervention in patients with VHL disease. Development of new cysts was associated with a larger number of cysts at study enrollment and younger age. Total peritumoral cyst burden was associated with germline partial deletion of the VHL gene.

Abstract
OBJECT The tumors most frequently associated with von Hippel-Lindau (VHL) disease are hemangioblastomas. While they are associated with significant neurological impairment and mortality, their natural history and optimal management have not been fully defined. METHODS Patients with VHL were enrolled in a prospective study designed to define the natural history of CNS hemangioblastomas. In the present analysis, serial imaging, laboratory, genetic, and clinical data were evaluated in those with at least 2 years of follow-up data. RESULTS At study entrance 225 patients (111 males, 114 females) harbored 1921 CNS hemangioblastomas in the supratentorial compartment (21 tumors [1%]), cerebellum (865 [45%]), brainstem (129 [7%]), spinal cord (689 [36%]), cauda equina (212 [11%]), and nerve roots (5 [0.3%]; follow-up 15,819 hemangioblastoma-years). Increased tumor burden was associated with partial deletions in the VHL gene (p = 0.005) and male sex (p = 0.002). Hemangioblastoma development (median 0.3 new tumors/year) was associated with younger age (p < 0.0001) and more tumors at study entrance (p < 0.0001). While 1278 hemangioblastomas (51%) did not grow, 1227 hemangioblastomas (49%) grew in a saltatory (886 [72%]), linear (76 [6%]), or exponential (264 [22%]) pattern. Faster tumor growth was associated with male sex (p = 0.001), symptomatic tumors (p < 0.0001), and tumors associated with cysts (p < 0.0001). Location-dependent tumor size was the primary predictor of eventual symptom formation (159 symptomatic tumors [6.3%]; area under the curve > 0.9). CONCLUSIONS Central nervous system hemangioblastoma burden in VHL is associated with partial germline deletions and male sex. Unpredictable growth of hemangioblastomas compromises assessment of nonsurgical therapies. The judicious treatment of symptom-producing hemangioblastomas, while avoiding unnecessary treatment of asymptomatic tumors that may not progress, can provide clinical stability.

Abstract
von Hippel-Lindau (VHL) disease is a rare, inherited neoplastic disease characterized by hemangioblastomas (HBL) of the central nervous system (CNS), retinal angiomas, renal cell carcinomas (RCC), pancreatic endocrine tumors (PETs), pheochromocytomas, paragangliomas, and visceral cysts. We encountered a large VHL family in northwest China and conducted a systematic screening of the family members based on their epidemiological and clinical characteristics. A self-designed questionnaire was used to collect the general sociodemographic and health information of the family members. For the preliminary family screening, physical examination and abdomen B ultrasonography were performed. The suspected patients were subjected to cranial computerized tomography and fundus examination. The clinical data of the patients with confirmed VHL disease were collected from hospital records. A total of 63 lineal descendants in six generations were observed in the family (generations O, A, B, C, D, E), including 9 dead suspected cases (6 males, 3 females) and 10 living cases (2 males, 8 females). Among the 10 living cases, 4, 2, 1, 3, 4, 8, and 2 manifested HBLs of the CNS, PETs, RCC, pancreatic cysts, renal cysts, pheochromocytomas (4 hemi and 4 bilateral), and paragangliomas, respectively. Data showed that the morbidity of VHL disease in generation C was lower than that in generation B, but the age of onset was younger. This study is the first to report VHL disease in northwest China and VHL-associated PET cases in Chinese. Therefore, follow-up checkups of the family should be focused on younger generations. Proper family screening protocols should be followed for the treatment of patients with VHL disease.

Abstract
We evaluated the clinicopathological outcome of von Hippel-Lindau (VHL)-patients who had mainly undergone nephron sparing surgery (NSS) for renal cell carcinoma (RCC) when the tumour diameter has reached 4.0 cm. Multiple, bilateral RCC with high recurrence rates and subsequent repeated interventions, followed by increasing risk for end-stage renal failure and metastases is characteristic for VHL. NSS is widely used for VHL-associated RCC at 3.0 cm cut-off. 54 VHL patients underwent NSS, nephrectomy or thermal ablation for RCC. We analysed time to second treatment, overall and cancer specific survival, intra- and post-operative data as well as tumour characteristics. We also examined the effects of delaying removal of RCC to 4.0 cm cut-off. Median follow-up was 67 months. 54 patients underwent 97 kidney treatments. 96 % of first and 67 % of second interventions comprised of NSS. 0 % metastases were observed in the group with largest tumour size ≤4 cm. The probability for second surgery was 21 %, at 5 years and 42 % at 10 years. Median time to second NSS was 149.6 months. The overall and cancer specific survival rate was 96.5 and 100 % at 5-year follow-up, and 82.5 and 90.5 % respectively at 10-year follow-up. Median delay to second NSS at 4.0 cm cut-off versus 3.0 cm was 27.8 months. NSS was both successfully used in first and second surgery and to some extent even in third surgery. By following a strict surveillance protocol it is possible to support a 4.0 cm-threshold strategy for NSS, based on the assumption that delaying time to second NSS prevents patients from premature renal failure.

Abstract
Pancreatic cysts are a heterogeneous group of lesions, which can be benign or malignant. Due to improved imaging techniques, physicians are more often confronted with pancreatic cysts. Little is known about the origin of pancreatic cysts in general. Von Hippel-Lindau (VHL) disease is an atypical ciliopathy and inherited tumor syndrome, caused by a mutation in the VHL tumor suppressor gene encoding the VHL protein (pVHL). VHL patients are prone to develop cysts and neuroendocrine tumors in the pancreas in addition to several other benign and malignant neoplasms. Remarkably, pancreatic cysts occur in approximately 70% of VHL patients, making it the only hereditary tumor syndrome with such a discernible expression of pancreatic cysts. Cellular loss of pVHL due to biallelic mutation can model pancreatic cystogenesis in other organisms, suggesting a causal relationship. Here, we give a comprehensive overview of various pVHL functions, focusing on those that can potentially explain pancreatic cyst development in VHL disease. Based on preclinical studies, cilia loss in ductal cells is probably an important early event in pancreatic cyst development.

Abstract
BACKGROUND Central nervous system (CNS) hemangioblastoma (HB) is one of the most common manifestations in von Hippel-Lindau disease (VHL), but large-scale studies on clinical features of CNS HB in VHL are scarce. METHODS On the basis of the results of a questionnaire, we collected data of VHL patients with CNS HB. RESULTS The total number of CNS HBs in 111 VHL patients (male 59, female 52) was 264 with the following distributions: cerebellar, 65.4 %; brainstem, 9.9 %; spinal cord, 23.9 %; and pituitary, 1. 1 %. The follow-up period was 0.6 to 39.2 years, with the mean 12.5 years. Patients bearing brainstem or spinal cord HB also had another HB significantly more frequently than those bearing cerebellar HBs (P < 0.05). The mean onset age of CNS HB was 29.1 years, and that of patients bearing a single HB (mean 34.4 years) was significantly greater than that of multiple HBs (mean 25.7 years). Patients with multiple HBs under 40 years are more dominant than those with a single HB. The distribution rate of brainstem HB is significantly smaller in patients below 30 years than patients above 29 years. Although ECOG PS score increased along with number of operations, the onset age decreased with increasing number of operations. The mean ECOG PS score of patients below 20 years is significantly smaller than patients above 19 years. CONCLUSIONS When the onset age of CNS HB is under 40 years, and CNS HB is located at the brainstem or spinal cord HB, the probability of multiple occurrence can be predicted. Since patients with an onset age under 20 years old preserve a high performance status, early detection of CNS HB would be important. In addition, since a multiple operations aggravate performance status, number of operations should be reduced.

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
INTRODUCTION Hemangioblastomas (HBLs) comprise approximately 2% of all primary central nervous system (CNS) tumors. Although histological features of this rare tumor are generally benign, its outcome is often unfavorable due to high risk of recurrence and multifocal localization. HBLs can be detected as sporadic or associated with Von Hippel-Lindau disease. Diffuse neonatal hemangiomatosis (DNH) presents with multiple, progressive, rapidly growing cutaneous hemangiomas associated with widespread visceral hemangiomas in the liver, lungs, gastrointestinal tract, brain, and meninges. DNH with predominant CNS involvement is rarely reported. Herein, we present a neonatal case of cerebellar HBL associated with DNH. CASE REPORT A 5-day-old male baby was referred with complaints of multiple cutaneous lesions. Purple papules were noted on the trunk, extremities, and the head. Thoracic magnetic resonance imaging demonstrated multiple hyperintense lesions on the chest wall and apex of the right lung. On MRI, a 3×2-cm mass lesion in the right cerebellar hemisphere was detected. Total resection of the mass and ventriculoperitoneal shunting was performed. Histopathologic examination confirmed the diagnosis of HBL. Steroid therapy was administered for disseminated hemangiomatosis, and the lesions showed regression; the patient showed good clinical recovery. The parents refused further treatment, and he was out of our control when he was 9 months old. CONCLUSION According to our knowledge, the presented newborn is the second case of cerebellar HBL associated with diffuse skin and visceral hemangiomas in the English medical literature. Clinicians must be vigilant about the predictive value of visceral and/or cutaneous hemangioma for an associated intracranial HBL.

Abstract
BACKGROUND Central nervous system (CNS) hemangioblastomas are a benign condition, which can be permanently cured by complete surgical removal. However, the vascular nature of these lesions and difficulties in localizing the tumors account for operative morbidity and recurrence. Power Doppler flow sonography has been proven useful during surgical removal of other vascular lesions. OBJECTIVE To evaluate the usefulness of Power Doppler flow sonography for hemangioblastoma. METHODS We used the SonoWand Invite (Sonowand AS, Trondheim, Norway) intraoperative navigation system in a consecutive series of hemangioblastomas operated on at our institution. Patients with von Hippel-Lindau (VHL) disease as well as sporadic hemangioblastomas were included. RESULTS The system was used on n = 64 consecutive hemangioblastomas operated on at our institution from 2007 to 2009. The tumors were localized in the cerebellum (n = 26), spinal cord (n = 27), brainstem (n = 10), and supratentorial (n = 1). In VHL disease was diagnosed 53 patients, and germline mutations of the VHL tumor suppressor gene were identified in 98%. Average tumor size was 1782 mm and 45% of the tumors were cystic. Forty-two of 64 tumors could be localized by grayscale sonography. All tumors were visible on power Doppler flow sonography. However, in 40 cases, only the pathological vessels and not the solid tumor itself enhanced on power Doppler. Postoperative MRI follow-up revealed remnant/recurrent tumors in 2 cases. CONCLUSION Power Doppler flow sonography is a sensitive intraoperative tool to guide the surgical approach and resection and provides reliable resection control in surgery of CNS hemangioblastoma.

Abstract
Supratentorial hemangioblastoma is a rare form of hemangioblastoma; little information is available regarding prognosis, treatment, and clinical characteristics, because the available literature is primarily composed of case reports and small case series. Therefore, we performed a systematic review of the literature to analyze clinical characteristics, disease progression, and surgical outcomes with respect to survival for supratentorial hemangioblastomas. The rate of progression-free survival (PFS) was determined using Kaplan-Meier analysis. Differences in categorical factors, including location of tumor and diagnosis of von Hippel-Lindau (VHL) disease, were analyzed using the Pearson χ(2) test. A total of 106 articles met the search criteria, which combined for a total of 132 patients. Of the patients with supratentorial tumors, 60% had VHL disease, and 31 (84%) of 37 patients with tumors in the sellar/suprasellar region had associated VHL (χ(2), P < .001). Five-year PFS for gross-total resection and subtotal resection were 100% and 53%, respectively (Log rank, P < .01). On the basis of our analysis of the literature on published cases of supratentorial hemangioblastoma, gross-total resection appears to be superior to other treatment modalities in extending PFS. Von Hippel-Lindau disease is positively correlated with supratentorial hemangioblastoma when compared with non-supratentorial CNS hemangioblastomas, particularly when present in the sellar/suprasellar region.

Abstract
Von Hippel-Lindau (VHL) disease is a rare autosomal dominant syndrome (1/36,000 live births) with highly penetrance that predispose to the development of a panel of highly vascularized tumors (model of tumoral angiogenesis). Main manifestations include central nervous system (CNS) and retinal haemangioblastomas, endolymphatic sac tumors, clear-cell renal cell carcinomas (RCC), phaeochromocytomas and pancreatic neuroendocrine tumors. RCC has become the first potential cause of mortality and VHL disease is the main cause of inherited RCC. The disease is caused by germline mutations in the VHL tumor-suppressor gene that plays a major role in regulation of the oxygen-sensing pathway by targeting the hypoxia-inducible factor HIF for degradation in proteasome. VHL has also major HIF-independent functions, specially in regulation of primary cilium, extracellular matrix and apoptosis. Somatic inactivation of the VHL gene is the main molecular event in most sporadic RCC and the treatment of advanced RCC has been revolutionized by targeted therapy with drugs that block angiogenesis. These drugs are now in first line in metastatic sporadic RCC and have shown promising results for RCC, pancreatic neuroendocrine tumors and malignant pheochromocytomas in VHL patients.

Abstract
OBJECTIVE To evaluate the growth kinetics of renal cell carcinoma (RCC) in von Hippel-Lindau (VHL) disease in a large trial by CT/MRI scan. VHL disease is a multisystemic disorder predisposing to renal cysts and cancer. There is a general assumption that VHL-associated RCC presents slower growth rates than sporadic RCC. PATIENTS AND METHODS We describe growth kinetics of 96 renal tumours in 64 VHL patients with analysed germline mutation (54/64 treated, 10/64 active surveillance) over a mean follow-up of 54.9 months. We calculated tumour volume, growth rate, multiplication of tumour volume per year and overall, as well as tumour volume doubling time. RESULTS The mean growth rate of 96 tumours was 4.4 mm/year (SD 3.2, median 4.1 mm/year), mean volume doubling time was 25.7 months (SD 20.2, median 22.2 months). We saw a median 1.4-fold increase in tumour volume per year. At treatment time point, VHL kidneys comprised 39% tumour and 15.7% cyst volume fraction. We saw no correlation between tumour size and growth parameters. CONCLUSION VHL-associated RCC show large variances in tumour growth behaviour. Compared to the literature, in our study the growth rates (mm/year) of RCC in VHL disease did not differ from those of sporadic RCC. Fast tumour growth increases the risk for metastases.

Abstract
BACKGROUND Supratentorial hemangioblastomas are rare lesions, occurring either sporadically or in von Hippel-Lindau disease. OBJECTIVE Following recent advances in our understanding of the natural history of von Hippel-Lindau-associated cerebellar and spinal hemangioblastomas, we conducted a study of the natural history of supratentorial hemangioblastomas in von Hippel-Lindau disease. METHODS We reviewed a series of 18 supratentorial hemangioblastomas in 13 patients with von Hippel-Lindau disease. Clinical, genetic, and serial imaging data and operative records were analyzed. RESULTS Hemangioblastomas were most commonly seen in the temporal lobe. Only 6 tumors had a cyst at diagnosis or during follow-up, and only 6 patients had associated symptoms at presentation or during follow-up. The most frequent clinical presentations were intracranial hypertension and visual loss. Of 14 tumors with documented serial imaging, 13 demonstrated tumor growth. Rates and patterns of tumor growth were unique to each patient. The mechanism of cyst formation described in other locations was also demonstrated in the supratentorial region. Patterns of peritumoral edema and rate of cyst formation seemed to be influenced by the presence of anatomic barriers. Germline VHL mutation was identified in all patients, but no specific genotype-phenotype correlation was found, although a familial predisposition is suggested. CONCLUSION This series illustrates the wide variation in tumor locations, patterns of growth, and edema progression seen in supratentorial hemangioblastomas and adds to our knowledge of the natural history of hemangioblastomas.

Abstract
From January 2000 to January 2009, 15 patients presented with large solid hemangioblastomas of the posterior fossa; eight of these patients were also diagnosed with von Hippel-Lindau (VHL) disease. Diagnostic imaging showed large vascular lesions. All 15 patients underwent surgery through a suboccipital ipsilateral, modified far-lateral, suboccipital midline or suboccipital supracerebellar approach. Preoperative embolization was attempted in seven patients. Complete removal of the tumor was performed in all patients. An overall neurological improvement was observed in 11 of the 15 patients, corresponding to 61.5%. During follow-up, six patients, all with VHL disease, developed recurrence. Two patients died of renal cell carcinoma after 1 year. Our favorable outcomes suggest that surgical resection is the optimal treatment for patients with large solid hemangioblastomas of the posterior fossa. With improved microsurgical techniques and a better understanding of the vascular pattern of this type of tumor, total microsurgical removal can be performed with low mortality.

Abstract
OBJECT Despite the frequent multiplicity and development of new spinal cord hemangioblastomas that require multiple resections in patients with von Hippel-Lindau (VHL) disease, the long-term effects of spinal surgery on spinal column stability in this neoplasia disorder are not known. To determine the effect of multilevel cervical laminectomy for spinal cord tumor resection in VHL, the authors analyzed long-term clinical and radiographic outcomes. METHODS The authors included consecutive patients enrolled in a prospective VHL disease natural history study who underwent cervical laminectomy(s) for spinal cord hemangioblastoma resection. Serial clinical examinations, neck disability indices, and radiographs (static and dynamic), as well as operative records, were analyzed. RESULTS Twenty-five adult patients (16 female, 9 male) with VHL disease underwent 34 operations (mean 1.4 ± 0.7 [± SD]/patient) for the resection of cervical spinal cord hemangioblastomas (mean number of lamina removed/surgery 3.0 ± 1.3). The mean age at surgery was 33.9 ± 11.9 years (range 18-61 years), and the mean follow-up duration was 9.1 ± 5.6 years. At last follow-up, radiographic criteria indicated that 9 patients (36%) had spinal column instability, 13 patients (52%) developed a cervical spinal deformity, 4 patients (16%) developed moderate to severe neck disability, and 3 patients (12%) met the criteria for clinical instability. Removal of the C-2 lamina was associated with the development of clinical instability (p = 0.02, Fisher exact test); older age at surgery was associated with the development of cervical deformity (p = 0.05, logistic regression); and a greater number of operations (suboccipital-T4) were associated with increased neck disability indices (p = 0.01, linear regression). CONCLUSIONS Whereas patients with VHL disease will often require multiple laminectomies for cervical spinal cord hemangioblastoma resection, a limited number of patients (12%) will develop clinical instability. Because prophylactic cervical instrumentation confers limited benefit at the time of spinal cord tumor resection for most patients, and because these patients need life-long MR imaging of the spinal cord, the quality of which may be affected by instrumentation, longitudinal clinical and radiological evaluation may be used to determine which patients will require stabilization.

Abstract
OBJECT Brainstem hemangioblastomas are frequently encountered in patients with von Hippel-Lindau (VHL) disease. These tumors can cause significant morbidity, and their optimal management has not been defined. To better define the outcome and management of these tumors, the authors analyzed the long-term results in patients who underwent resection of brainstem hemangioblastomas. METHODS Consecutive patients with VHL disease who underwent resection of brainstem hemangioblastomas with a follow-up of 12 months or more were included in this study. Serial functional assessments, radiographic examinations, and operative records were analyzed. RESULTS Forty-four patients (17 male and 27 female) underwent 51 operations for resection of 71 brainstem hemangioblastomas. The most common presenting symptoms were headache, swallowing difficulties, singultus, gait difficulties, and sensory abnormalities. The mean follow-up was 5.9 ± 5.0 years (range 1.0-20.8 years). Immediately after 34 operations (66.7%), the patients remained at their preoperative functional status; they improved after 8 operations (15.7%) and worsened after 9 operations (17.6%) as measured by the McCormick scale. Eight (88.9%) of the 9 patients who were worse immediately after resection returned to their preoperative status within 6 months. Two patients experienced functional decline during long-term follow-up (beginning at 2.5 and 5 years postoperatively) caused by extensive VHL disease-associated CNS disease. CONCLUSIONS Generally, resection of symptomatic brainstem hemangioblastomas is a safe and effective management strategy in patients with VHL disease. Most patients maintain their preoperative functional status, although long-term decline in functional status may occur due to VHL disease-associated progression.

Abstract
Von Hippel-Lindau syndrome (VHLS) is an autosomal dominant familial cancer syndrome arising from germ-line inactivation of the VHL gene on the short arm of chromosome 3. VHLS manifests in a myriad of hyper-vascular tumors of both benign and malignant nature. Incidence of VHLS is roughly 1 in 36,000 live births and has over 90% penetrance by the age of 65. Improved understanding of the natural history and biology of VHLS has led to the introduction of screening protocols, early interventions and improved treatments, all of which resulted in a substantially improved prognosis for this disease. Further details regardingvariegated molecular pathways and mechanisms ofVHLS are emerging with the subsequent advent of novel treatment protocols that are currently in clinical trials.

Abstract
Abstract
HEMANGIOBLASTOMAS OCCUR IN 2% to 15% of reported series of intramedullary spinal cord tumors. They are benign, highly vascular tumors that can be cured with surgical resection. Complete removal of these tumors with low morbidity is possible with current microneurosurgical techniques and a thorough understanding of the typical relationship of the tumor to adjacent neural structures. We describe our experience with 16 intramedullary and 2 lumbosacral nerve root hemangioblastomas and review the relevant published literature. A detailed discussion of the operative technique is provided along with an operative video. Three illustrative cases are used to demonstrate clinical considerations that can arise with these tumors, including surgery during pregnancy, symptoms related to syrinx or syringomyelia, and postoperative consequences of neurological deficits.

Abstract
von Hippel-Lindau disease (vHL) is a hereditary multisystem cancer syndrome requiring lifelong prophylactic surveillance. Current surveillance recommendations rely on best medical judgement and no evidence of effect exists. We aimed to evaluate the capability of surveillance in manifestation detection, before these turn symptomatic, in order to prevent disabling or even fatal outcomes. We focus on surveillance of central nervous system (CNS) hemangioblastomas, retinal hemangiomas and renal cell carcinoma (RCC) as these have the most severe consequences. On the basis of full medical records from 54 living vHL-mutation carriers, risks of intercurrent manifestations in-between surveillance examinations were determined and clinical consequences of surveillance findings evaluated. Current recommendations of annual ophthalmic and abdominal examinations corresponded to acceptably low intercurrent manifestation risks (1.7% and 1.2%, respectively), whereas recommendations of biennial CNS imaging corresponded to a risk of 7.2%. Annual CNS examinations, however, significantly reduces this risk to 2.7%. Furthermore, most CNS manifestations found due to surveillance (71%, 106 of 150) had clinical consequence for the patient. Also, pre-symptomatic surveillance increased cumulative incidence of clinical vHL diagnosis from 46% to 72% and from 89% to 94% by age 30 and 50 years, respectively. The present results promote optimization of surveillance, expectantly improving clinical vHL outcomes.

Abstract
Von Hippel-Lindau (VHL) disease is a rare multisystem familial tumor syndrome of autosomal dominant inheritance. Hallmark lesions include retinal, cerebellum and spinal cord hemangioblastomas, renal cell carcinomas, adrenal pheochromocytomas, angiomatous or cystic lesions of the kidneys, pancreas, and epididymis. We report a case of VHL disease in a 26-year-old patient who presented with exudative macular edema. Ocular and systemic studies revealed the presence of retinal and central nervous system hemangioblastomas, adrenal pheochromocytoma, multiple pancreatic, and kidney cysts. The retinal angiomas were successfully treated with argon laser photocoagulation and cryotherapy.
