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
Study Design Broad narrative review. Objectives Intramedullary spinal cord tumors (IMSCT) are rare neoplasms that can potentially lead to severe neurologic deterioration, decreased function, poor quality of life, or death. As such, a better understanding of these lesions is needed. The following article, part one of a two-part series, addresses IMSCT with regards to their epidemiology, histology, pathophysiology, imaging characteristics, and clinical manifestations. Methods The authors performed an extensive review of the peer-reviewed literature addressing the aforementioned objectives. Results Numerous IMSCT exist with varying epidemiology. Each IMSCT has its own hallmark characteristics and may vary with regards to how aggressively they invade the spinal cord. These lesions are often difficult to detect and are often misdiagnosed. Furthermore, radiographically and clinically, these lesions may be difficult to distinguish from one another. Conclusions Awareness and understanding of IMSCT is imperative to facilitate an early diagnosis and plan management.

Abstract
OBJECT
Hemangioblastomas are rare, benign, highly vascularized tumors that can be found throughout the neuraxis but are mainly located in the cerebellum and in the spinal cord. Spinal hemangioblastomas can present with motor and sensory deficits, whose severity varies according to the size and location of the tumor. Resection is the best treatment option to avoid neurological deterioration. The authors report surgical results in the treatment of intramedullary hemangioblastomas and discuss the technical nuances important to achieving total resection without adding new deficits.
METHODS
A consecutive series of patients with intramedullary hemangioblastomas operated on between 2000 and 2014 by the senior author (H.T.) is presented. The functional scale proposed by McCormick was used to evaluate the patients' neurological status before and after surgery.
RESULTS
Sixteen patients were included in the study and underwent 17 surgeries. Follow-up was at least 6 months. Age at presentation varied from 13 to 58 years (mean 33.8 years). Ten patients (62.5%) were males and 6 patients (37.5%) were females. Seven (43.75%) of the 16 patients had associated von Hippel—Lindau syndrome, with hemangioblastomas also presenting in other locations. Three patients had multiple tumors in the same segment in the spinal cord, and 10 patients (62.5%) presented with cysts. According to the site of presentation, 11 tumors (68.75%) were localized at the cervical region (including the cervicomedullary junction) and 5 tumors (31.25%) at the thoracic level. Total resection was achieved in all cases, evidenced by postoperative MRI. Four patients had some functional worsening immediately after surgery. After 6 months, 1 patient had functional worsening compared with preoperative status, and 2 patients had clinical improvement. The majority of the patients remained clinically stable postoperatively.
CONCLUSIONS
Adequate knowledge of anatomy and the correct use of microsurgical techniques allowed total resection of these tumors, with minimal morbidity and maximum functional recovery. Outcome seems to be directly related to the neurological status before surgery.

Abstract
BACKGROUND von Hippel-Lindau (VHL) disease is an autosomal dominant disorder characterized by the development of multiple tumors in the central nervous system and visceral organs. In this study, we describe clinical features of pancreatic involvement in VHL disease, of which there have been few reported studies to date. METHODS We reviewed medical records of 63 VHL patients, diagnosed at Asan Medical Center between January 1995 and December 2013. Demographic, genetic, and radiologic features, and the clinical course of VHL patients with pancreatic involvement were retrospectively analyzed. RESULTS Among the 63 VHL patients, 55 (87.4%) had VHL-associated pancreatic lesions (male: female, 31:24; median age at onset, 33 years; range, 12-67 years). These presented as single simple cysts (n = 5, 9.1%), multiple simple cysts (n = 14, 25.5%), serous cystadenoma (n = 29, 52.7%), or neuroendocrine tumors (NETs) (n = 17, 30.9%). Genetic tests were performed on 35 of the 55 patients (63.6%) and VHL gene mutations were observed in 28 of them (80%). Of the 55 patients, 11 received surgical treatment, 2 received endoscopic ultrasonography-guided ethanol ablation therapy as local treatment for NET, and 42 patients were followed regularly without intervention (20%, 3.6%, and 76.4%, respectively). CONCLUSION Pancreatic involvement in VHL disease is common, with a prevalence of 87.4%. Serial screening imaging studies for the early detection of VHL-associated NET are necessary in individuals at risk of VHL disease. A large-scale epidemiological study of VHL disease is needed to examine the natural course of the disease and the prognosis for pancreatic involvement.

Abstract
von Hippel-Lindau (VHL) disease is an inheritable condition with an incidence of 1 in 36000 live births. Individuals with VHL develop benign and malignant tumors including retinal and central nervous system hemangioblastomas, clear cell renal cell carcinomas (RCC), pheochromocytomas, pancreatic neuroendocrine tumors and endolymphatic sac tumors (ELSTs). VHL is caused by germline loss of function of the VHL gene on one allele at chromosome 3p25-26. A somatic "second hit" event leads to the loss of the other allele and tumor formation. Loss of VHL function in cells leads to increased expression and stabilization of hypoxia inducible factor (HIF). VHL protein/HIF pathway has been implicated in tumorigenesis for hemangioblastomas, RCC and other VHL tumors. Clinical examination, imaging, and genetic testing for VHL mutations confirm VHL disease. Management of VHL disease largely consists of surgical resection of symptomatic tumors (hemangioblastomas), tumors prone to metastasize (RCC larger than 3cm), or tumors causing hormonal symptoms (pheochromocytomas). Despite advances in early diagnosis and management of VHL disease, life expectancy for VHL patients remains low at 40-52 years. Secondary effects from VHL manifestations are mitigated by routine surveillance and early detection. In this chapter, we summarize the current state of knowledge in VHL disease.

Abstract
Since the Von Hippel-Lindau (VHL) disease tumour suppressor gene VHL was identified in 1993 as the genetic basis for a rare disorder, it has proved to be of wide medical and scientific interest. VHL tumour suppressor protein (pVHL) plays a key part in cellular oxygen sensing by targeting hypoxia-inducible factors for ubiquitylation and proteasomal degradation. Early inactivation of VHL is commonly seen in clear-cell renal cell carcinoma (ccRCC), and insights gained from the functional analysis of pVHL have provided the foundation for the routine treatment of advanced-stage ccRCC with novel targeted therapies. However, recent sequencing studies have identified additional driver genes that are involved in the pathogenesis of ccRCC. As our understanding of the importance of VHL matures, it is timely to review progress from its initial description to current knowledge of VHL biology, as well as future prospects for novel medical treatments for VHL disease and ccRCC.

Abstract
BACKGROUND Two patients who had received a total resection of cerebellar hemangioblastoma developed cerebrospinal fluid dissemination during a long-term follow-up period. We present this rare disease with discussion based on the literature. CASE DESCRIPTION The patients were two women aged 45 and 57 years. In the cerebellar hemisphere, one patient had cystic hemangioblastoma of mural nodule type and the other had solid type. Both the patients successfully underwent total resection by craniotomy. They presented no mutations in the von Hippel-Lindau disease (VHL) gene or lesions in the other organs. One patient developed local recurrence 38 months after the initial surgery, and received stereotactic radiosurgery. Three spinal cord tumors developed 91 months later, and the tumors were disseminated to the entire cerebrospinal cavity 107 months later. The other patient developed hydrocephalus 53 months after the initial surgery with tumor tissues disseminated in the intracranial subarachnoid space. The conditions of the two patients gradually aggravated despite treatment with ventriculo-peritoneal shunt and irradiation to the whole brain and whole spinal cord. CONCLUSION Cerebrospinal fluid dissemination of cerebellar hemangioblastoma was found dominantly in non-VHL patients. The diagnosis was made 10 years after the initial surgery. Irradiation therapy was performed, but the patients died about 2 years after the diagnosis was given. Molecular targeted therapies including vascular proliferation suppression have been attempted lately, but no effective therapy has been established. Early diagnosis of dissemination as well as combination of aggressive excision and stereotactic radiosurgery are considered to be appropriate for current interventions.

Abstract
There are approximately 100 genes which when mutated are known to predispose to one or more forms of cancer. Currently, genetic testing is offered for many of these, either as single genes or as multi-gene panels. Features of hereditary cancer include a positive family history of cancer, early age of onset and the appearance of multiple primary cancers in one individual. In some cases multiple cancers may be of the same site (e.g., bilateral breast cancer) and in other cases they may be at different sites. Various combinations of cancer sites may be indicative of specific cancer syndromes such as the breast ovarian cancer syndrome. Genetic testing should be offered to individuals who have experienced multiple primary cancers in some circumstances, the genetic counselor should review the ages of sites of cancer, their pathologic features and the family history of cancer as part of the pre-test evaluation.

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 disease is a hereditary neoplastic syndrome, characterized by malignant and benign lesions in multiple organs. Pancreatic involvement is very common and is in general asymptomatic. We describe a case of malabsorption with severe hypocalcemia in a patient with von Hippel-Lindau disease, caused by exocrine pancreatic insufficiency, probably due to severe cystic transformation of the pancreas.

Abstract
Intracranial hemangioblastomas are benign vascular tumors. The peak age of incidence is between 20 to 50 years. Hemangioblastomas rarely occur in patients over the age of 65. To our knowledge there is no review of the prevalence and clinical features in an elderly population. We reviewed our 12 year experience with intracranial hemangioblastomas, and characterized the clinical features of hemangioblastomas in patients over the age of 65. We present a 72-year-old man with a cerebellar mass initially thought to be a metastasis as an illustrative case. We reviewed our pathology database and identified all patients with a histopathologically confirmed diagnosis of hemangioblastoma over the last 12 years in a large tertiary adult hospital; all patients were over the age of 18. Of all cases of hemangioblastoma in the last 12 years, six of 77 (7.7%) occurred in patients over the age of 65. All were cerebellar in location, and none were associated with von-Hippel Lindau disease. Hemangioblastomas are uncommon, but not rare, in patients over the age of 65, and should be included in the differential diagnosis of patients presenting with gait ataxia and a cerebellar lesion in this age group.

Abstract
Genetic testing at a distance is commonplace where members of a family with a segregating germline mutation are geographically separated. For the most part, this challenge is addressed through the intervention of health professionals in taking and/or processing blood samples for subsequent couriering of DNA to a referral laboratory. In some circumstances, however, the collecting of pivotal clinical material may involve direct patient involvement. We describe such a situation where noninvasive saliva samples were provided by members of a family manifesting Von Hippel-Lindau (VHL) disease. The analysis identified a novel mutation in the VHL gene that was used to exclude other family members as being at risk of VHL disease.

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
Hypoxic microenvironments frequently exist in many solid tumours with oxygen levels fluctuating temporally and spatially from normoxia to hypoxia. The response to hypoxia in human cells is mainly regulated by hypoxia-inducible factors (HIFs), a family of transcription factors which orchestrate signalling events leading to angiogenesis and tumorigenesis. Several events conspire together to lead to the stabilization of HIF-α, commonly expressed in many cancer cell types. These events can result from low oxygen tensions occurring within the expanding tumour mass to produce hypoxic microenvironments or from mutations whereby the HIFs cause changes in expression of genes involved in several cellular functions. Hypoxia-mediated HIF-α regulation has gained significant prominence in tumour biology over recent years, and the hypoxic microenvironments have been shown to facilitate and trigger major molecular and immunological processes necessary to drive the progression of tumours to malignancy. More recently, it has been realized that the hypoxic microenvironments also play significant roles in shielding tumour cells from immune attack by promoting immune suppression. In addition, the hypoxic microenvironment promotes many other oncogenic events, such as the metabolic reconfiguration of tumour cells, neovascularization, epithelial to mesenchymal transition (EMT), and cancer stem cell renewal and accumulation. This article reviews the molecular mechanisms underlying tumour hypoxia and their pro-tumour contributions, such as immune suppression, development of nascent and more permeable tumour vasculature, selective cancer stem cell renewal, accumulation, mobilization and promotion of EMT leading to tumour cell metastasis.

Abstract
Various missense mutations in the VHL gene have been reported among patients with familial bilateral pheochromocytoma. However, the p.Arg82Leu mutation in the VHL gene described here among patients with familial bilateral pheochromocytoma, has never been reported previously in a germline configuration. Interestingly, long-term follow-up of these patients indicated that the mutation might have had little impact on the normal function of the VHL gene, since all of them have remained asymptomatic. We further attempted to correlate this information with the results obtained by in silico analysis of this mutation using SIFT, PhD-SNP SVM profile, MutPred, PolyPhen2, and SNPs&GO prediction tools. To gain, new mechanistic insight into the structural effect, we mapped the mutation on to 3D structure (PDB ID 1LM8). Further, we analyzed the structural level changes in time scale level with respect to native and mutant protein complexes by using 12 ns molecular dynamics simulation method. Though these methods predict the mutation to have a pathogenic potential, it remains to be seen if these patients will eventually develop symptomatic disease.

Abstract
Patients with von Hippel-Lindau disease carry a germline mutation of the Von Hippel-Lindau (VHL) tumor-suppressor gene. We discuss the molecular consequences of loss of VHL gene function and their impact on the nervous system. Dysfunction of the VHL protein causes accumulation and activation of hypoxia inducible factor (HIF) which can be demonstrated in earliest stages of tumorigenesis and is followed by expression of VEGF, erythropoietin, nitric oxide synthase and glucose transporter 1 in VHL-deficient tumor cells. HIF-independent functions of VHL, epigenetic inactivation of VHL, pVHL proteostasis, and links between loss of VHL function and developmental arrest are also described. A most intriguing feature in VHL disease is the occurrence of primary hemangioblastic tumors in the nervous system, the origin of which has not yet been entirely clarified, and current hypotheses are discussed. Endolymphatic sac tumors may extend into the brain, but originally arise from proliferation of endolymphatic duct/sac epithelium; the exact nature of the proliferating epithelial cell, however, also has remained unclear, as well as the question why tumors almost consistently develop in the intraosseous portion of the endolymphatic sac/duct only. The epitheloid clear cell morphology of both advanced hemangioblastoma and renal clear cell carcinoma can make the differential diagnosis challenging, recent developments in immunohistochemical differentiation are discussed. Finally, metastasis to brain may not only be caused by renal carcinoma, but may derive from VHL disease-associated pheochromocytoma/paraganglioma, or pancreatic neuroendocrine tumor.

Abstract
OBJECTIVES/HYPOTHESIS To define the surgical treatment and outcomes of von Hippel-Lindau (VHL) disease-associated endolymphatic sac tumors (ELSTs), we analyzed consecutive VHL patients who underwent ELST resection. STUDY DESIGN Retrospective investigation of consecutive VHL patients who underwent resection of ELSTs at a clinical research center between 1999 and 2010. METHODS Analysis of serial clinical examinations, audiograms, imaging studies, and operative findings were analyzed. RESULTS Thirty-one consecutive patients with ELSTs (15 males, 16 females) underwent resection of 33 tumors (mean follow-up, 49.9 ± 48.0 months; range, 1.0-116 months). One patient had bilateral ELST resections and one patient underwent reoperation for recurrence. Mean age at surgery was 38.2 ± 10.2 years (range, 12-67 years). Whereas 29 ears (88%) had direct radiographic evidence of an ELST, four ears (12%) did not. Mean tumor size was 1.3 ± 1.1 cm (range, 0.2-5.2 cm). Whereas two patients (two ears, 6%) were asymptomatic, 29 patients (31 ears, 94% of ears) had associated audiovestibular symptoms, including sensorineural hearing loss (28 ears, 84%), tinnitus (24 ears,73%), and vertigo (21 patients, 68%). Postoperatively, hearing was stabilized (27) or improved (three) in 97% of 31 ears. Complete tumor resection was achieved in 30 ears (91% of 33 ears). Complications included cerebrospinal fluid leak in two ears (6%) and transient lower cranial nerve palsy in one ear (3%). CONCLUSIONS Surgical resection of ELSTs can be performed with hearing preservation and a reduction in audiovestibular dysfunction. Early surgical resection can prevent or decrease disabling audiovestibular symptoms, enhance the opportunity for complete resection, and preserve hearing.

Abstract
OBJECTIVE Characterization of the structural and functional progression of ocular von Hippel-Lindau (VHL) disease and analysis of patient factors influencing disease progression. DESIGN Retrospective analysis of a case series from a longitudinal, observational study. PARTICIPANTS Two hundred forty-nine participants with clinically defined systemic VHL disease and more than 2 years of ophthalmic follow-up. METHODS Standardized scoring of ocular phenotype and systemic characteristics was performed at each study visit and was analyzed longitudinally to determine progression of ocular VHL disease. MAIN OUTCOME MEASURES Measures evaluated include: visual acuity, features of ocular VHL disease (presence, location, number, and extent of retinal capillary hemangioblastomas [RCHs]), germline mutation in the VHL gene, demographics (age, gender, age at onset of ocular disease), and patient characteristics (smoking status, body mass index). RESULTS Most participants demonstrated relative anatomic and functional stability in ocular VHL disease status over a mean follow-up of 8.2 ± 4.0 years. Approximately three quarters (73%) of participants without ocular VHL disease at baseline remained disease free at the end of follow-up. Among eyes with ocular VHL disease at baseline, 88% did not demonstrate RCHs in a new retinal location, 70% remained stable in RCH number, and 79% remained stable in the extent of RCH involvement. Mean visual acuity for all study eyes (n = 498) decreased by 5.1 ± 0.6 letters across follow-up, with 16.1% of study eyes decreasing by more than 10 letters in visual acuity. Among eyes affected at baseline, greater vision loss was associated with the presence of juxtapapillary RCHs, development of RCH in a new location, and increase in peripheral RCH number and extent. Younger baseline age, younger age at onset of ocular VHL disease, involvement of the fellow eye with ocular VHL disease, and missense or protein-truncating germline mutations were associated significantly with increased anatomic involvement and functional deterioration. CONCLUSIONS Patients with ocular VHL disease maintain relative anatomic and functional stability, with only a minority demonstrating marked anatomic progression and vision loss. Systemic and ocular risk factors for anatomic progression and vision loss can help practitioners identify patients with a higher risk profile for counseling, closer follow-up, and proactive treatment.

Abstract
BACKGROUND von Hippel-Lindau (vHL) disease is a rare condition that leads to characteristic lesions within many different body systems. Pancreatic manifestations of vHL cover a wide spectrum of pathologies, and thus, accurate characterization and management is critical. METHODS A comprehensive and systematic text word and MeSH search of the medical literature was performed to identify studies where information regarding the prevalence, clinical characteristics, and management recommendations could be extracted. RESULTS Eleven studies were identified but 2 studies utilized the same data set. Of the 10 remaining studies, a total of 1,442 patients with vHL were available for analysis. Four hundred and twenty patients were examined for any type of pancreatic lesion, 362 for simple cysts or serous cystadenomas (SCAs), and 1,442 for neuroendocrine tumors (NETs). Of the 420 assessed for any pancreatic manifestation of vHL, 252 (60%) had a pancreatic lesion identified. Simple cysts that present as the sole manifestation of pancreatic disease were common and found in 169 of 362 (47%) patients. These are usually asymptomatic and do not normally require intervention. SCAs were reported in 39 of 362 (11%) patients and followed a similar benign course; resection is acceptable in symptomatic patients. NETs were identified in 211 of 1,442 (15%) patients, and 27 of 1,442 (2%) lesions behaved malignantly. Management of NETs depends on size, doubling time, and underlying genetics. Renal cell carcinoma is a characteristic in vHL, but there were no cases of pancreatic metastases identified from the included studies. Adenocarcinomas of the pancreas are not pathogenically linked to vHL. CONCLUSIONS This review highlights the wide spectrum and high prevalence of pancreatic lesions in vHL. Simple cysts and SCAs are benign, but NETs require careful observation due to their malignant potential.

Abstract
Von Hippel-Lindau (VHL) disease is a dominantly inherited familial cancer syndrome with a variety of benign and malignant tumors such as retinal and central nervous system hemangioblastomas, endolymphatic sac tumors, renal cysts and tumors, pancreatic cysts and tumors, pheochromocytomas, and epididymal cystadenomas. Cross-sectional modalities (computed tomography and magnetic resonance imaging) as well as ultrasound play a major role in the initial evaluation and follow-up of the various manifestations of VHL disease. Ga-68-labeled somatostatin receptor analogs already have a significant role in the diagnosis, staging, and therapy management of neuroendocrine neoplasms and neural crest tumors. Herein, we report a case presenting a variety of malignancies in VHL and showing the usefulness of Ga-68 somatostatin receptor PET/CT as a one-stop-shop imaging modality in the management of VHL disease.

Abstract
Patients with von Hippel-Lindau disease (VHL) often harbor significant disease burden within the CNS, specifically craniospinal-axis hemangioblastomas and endolymphatic sac tumors (ELSTs). The majority (60-80%) of patients with VHL harbor hemangioblastomas, and 10-15% will develop ELSTs. Advances in the understanding of the natural history and outcomes associated with the surgical management of VHL-associated tumors have led to improved management of patients with VHL. Optimizing indications for surgical intervention and refining of surgical techniques for these lesions can reduce patient morbidity associated with the management of this syndrome. In this article, we review the various aspects of perioperative management of patients with VHL, surgical indications and general operative principles for the management of hemangioblastomas and ELSTs, and outcomes associated with the surgical treatment of these tumors.

Abstract
Unique features of tumours that can be exploited by targeted therapies are a key focus of current cancer research. One such approach is known as synthetic lethality screening, which involves searching for genetic interactions of two mutations whereby the presence of either mutation alone has no effect on cell viability but the combination of the two mutations results in cell death. The presence of one of these mutations in cancer cells but not in normal cells can therefore create opportunities to selectively kill cancer cells by mimicking the effect of the second genetic mutation with targeted therapy. Here, we summarize strategies that can be used to identify synthetic lethal interactions for anticancer drug discovery, describe examples of such interactions that are currently being investigated in preclinical and clinical studies of targeted anticancer therapies, and discuss the challenges of realizing the full potential of such therapies.

Abstract
OBJECTIVE To review the first reported cases of successfully treated pheochromocytoma and primary aldosteronism and to document the diagnostic and therapeutic advances that have occurred since the initial descriptions. METHODS The original case descriptions and the subsequent pertinent literature were reviewed. RESULTS The successful management of the initial cases of pheochromocytoma in 1926 and primary aldosteronism in 1954 was highlighted by keen clinical observation, clinical intuition, and application of scientific principles. Since those prismatic case descriptions, the technological advances in laboratory-based diagnosis, radiology-based tumor localization, and surgical approaches to the adrenal glands have been truly remarkable. CONCLUSIONS The evolution in the diagnosis and treatment of pheochromocytoma will continue to progress as we identify more genetic causes, develop biochemical markers for "preclinical" pheochromocytoma, identify better markers for malignant disease, and develop more effective treatment options for malignant pheochromocytoma. Over the next decade, we hope to determine the pathophysiology for bilateral idiopathic hyperaldosteronism, develop less invasive and less technically demanding tests to distinguish between unilateral aldosterone-producing adenoma and bilateral idiopathic hyperaldosteronism, determine where low renin hypertension stops and primary aldosteronism starts, and determine the impact of genetic and environmental factors on aldosterone secretion in patients with and without primary aldosteronism.

Abstract
The term cancer predisposition syndrome (CPS) encompasses a multitude of familial cancers in which a clear mode of inheritance can be established, although a specific gene defect has not been described in all cases. Advances in genetics and the development of new imaging techniques have led to better understanding and early detection of these syndromes and offer the potential for preclinical diagnosis of any associated tumors. As a result, imaging has become an essential component of the clinical approach to management of CPSs and the care of children suspected of having a CPS or with a confirmed diagnosis. Common CPSs in children include neurofibromatosis type 1, Beckwith-Wiedemann syndrome, multiple endocrine neoplasia, Li-Fraumeni syndrome, von Hippel-Lindau syndrome, and familial adenomatous polyposis. Radiologists should be familiar with these syndromes, their common associated tumors, the new imaging techniques that are available, and current screening and surveillance recommendations to optimize the assessment of affected children.

Abstract
A 75-year-old Japanese woman presented with a juxtapapillary retinal capillary hemangioma (RCH) in her left eye. Twelve months after the initial examination, the size of the hemangioma had increased and the exudation from the RCH involved the macula. Her best-corrected visual acuity (BCVA) had decreased from 0.8 to 0.3. A total of five intravitreal injections of bevacizumab (IVB; 1.25 mg) was given but the RCH did not respond. A photodynamic therapy (PDT) was done using multiple laser spots to avoid damaging the optic nerve head. After the first PDT, the subfoveal fluid was reduced but not completely gone. One week after the second PDT, a massive subretinal hemorrhage developed. The subretinal hemorrhage was successfully displaced by injecting intraocular sulfur hexafluoride (SF6) gas. At the 3-year follow-up examination, no subretinal hemorrhage or fluid was observed at the macula and the BCVA remained at 0.05. Our case was resistant to the combination of anti-vascular endothelial growth factor (VEGF) and PDT and had a rare massive subretinal hemorrhage. A further collection of RCH cases treated with anti-VEGF and PDT that would justify this treatment is necessary.

Abstract
The article describes paraganglioma case in woman with von Hippel–Lindau disease. She was found to be a carrier of a rare germline mutation in the VHL gene (393C>A; N131K). The patient developed large, untypical for von Hippel–Lindau disease, carotid body paraganglioma at the common carotid artery bifurcation. The carotid body paraganglioma coexisted with the haemangioblastoma situated intramedullary in region C5/C6. The haemangioblastoma reached the right-sided dorsal part of the spinal cord in section C5/C6. It produced radicular symptoms within C5/C6, followed by the later paresis of the right limbs. The haemangioblastoma was resected completely. Twelve months after the operation, the spinal symptoms receded and the carotid body paraganglioma still was asymptomatic. The current case of carotid body paraganglioma in patient with the 393C>A (N131K) missense mutation in the VHL gene, supports association of this specific mutation and VHL disease type 2, and suggests its correlation with susceptibility to paragangliomas.

Abstract
Von Hippel-Lindau disease is an inherited syndrome predisposing to a variety of benign and malignant neoplasms of the central nervous system and viscera that requires comprehensive screening and follow-up of individuals and their families. As such, it is important for the neurosurgeon to be aware of its clinical features and management issues. In this article we review the clinical aspects, management and surveillance of von Hippel-Lindau disease for neurosurgical practice.

Abstract
Although cerebellar hemangioblastomas are histopathologically benign, they yield a degree of malignant clinical behavior in long-term follow-up. We present two cases of long-term progression of renal cell carcinoma, which had been diagnosed as renal cysts during treatment for cerebellar hemangioblastoma. A 14-year-old male with von Hippel-Lindau disease was admitted for a cerebellar hemangioblastoma with multiple spinal hemangioblastomas and a renal cyst. After primary total resection of the cerebellar hemangioblastoma, the patient required two further surgeries after 111 and 209 months for a recurrent cerebellar hemangioblastoma. Furthermore, he underwent radical nephrectomy as his renal cyst had progressed to renal cell carcinoma 209 months after initial diagnosis. A 26-year-old male presented with multiple cerebellar hemangioblastomas associated with von Hippel-Lindau disease and accompanied by multiple spinal hemangioblastomas and multiple cystic lesions in the liver, kidney, and pancreas. He underwent primary resection of the cerebellar hemangioblastoma in association with craniospinal radiation for multiple intracranial/spinal masses. Unexpectedly, a malignant glioma developed 83 months after discovery of the cerebellar hemangioblastoma. At the same time, renal cell carcinoma, which had developed from an initial renal cyst, was diagnosed, and a radical nephrectomy was performed. In the view of long term clinical course, cerebellar hemangioblastoma associated with von Hipple-Lindau disease may redevelop even after primary total resection. In addition, associated lesions such as renal cysts may also progress to malignancy after the passing of a sufficient length of time.

Abstract
Background Von Hippel Lindau disease is an autosomal dominant multisystem/multitumoral cancer disease diagnosed by clinical, radiologic and genetic findings. Its prevalence has been estimated to be of 1/36000 inhabitants. The tumours can be benign or malignant. Case report We represent MR findings of a family with ten children. Mother and five siblings had von Hippel-Lindau disease. Conclusions Radiologic imaging is very important for the early diagnosis and treatment of asymptomatic patients. Diagnosing it early is important because the tumours in von Hippel Lindau disease are treatable. Also, an early detection allows the patient’s survival and quality of life. A multidisciplinary team approach is important in screening.

Abstract
Von Hippel-Lindau (VHL) disease is an autosomal dominant inherited cancer predisposition syndrome, characterized by development of a variety of neoplasms in multiple organs. Central nervous system hemangioblastoma (CHB) is the most common manifestation of VHL disease. The germline mutations in the VHL tumor suppressor gene are responsible for the inherited cancer predisposition syndrome. To expand the VHL mutation data and to investigate the tumorigenesis of VHL-associated CNS hemangioblastoma, 24 CHB tissue samples and blood samples of 14 patients from 10 Chinese VHL families were collected and subjected to molecular genetic analysis. Six distinctive germline mutations were identified, and the 601 G to C (Val130Phe) mutation is reported for the first time. Somatic mutations analysis of the VHL gene in VHL-associated CHB showed that loss of heterozygosity (LOH) occurred in more than half of the cases. In addition, expression of the ZAC1 tumor suppressor gene protein was studied using immunohistochemistry staining in CHB tissues with a specific polyclonal antibody. The ZAC1 protein was lost in all CHB. Our data exhibited high frequency of LOH of ZAC1 gene in VHL-associated CHB, indicating that ZAC1 may have a role in tumorigenesis of VHL-associated CHB.

Abstract
OBJECTIVES Explore the genetic and clinical incidence of von Hippel-Lindau disease in patients presenting with isolated central nervous system hemangioblastomas. RESULTS We report a 3.2% (1/31) and 25% (8/32) incidence of genetic and clinical VHL, respectively. One patient tested positive for a VHL mutation that has not previously been reported. This genotype phenotypically predicts VHL type 2B. We had seven patients with renal cysts. In a total follow-up of 33 person years, none of these cysts progressed to renal cell carcinoma. CONCLUSION von Hippel-Lindau disease anchored in germline mutations of the VHL gene is rare in the Norwegian population as opposed to clinical VHL disease, which appears to be relatively common in patients with apparently sporadic hemangioblastomas. There exists insufficient data regarding the natural history of patients with renal cysts, which makes it difficult to include or disregard these lesions as an entity of VHL disease.

Abstract
Von Hippel-Lindau disease is an uncommon, multisystem, multitumor disorder that can present in sporadic form but is more commonly inherited as an autosomal-dominant disease with high penetrance. Affected patients are at increased risk for developing multiple synchronous or metachronous benign or malignant, cystic, and vascular neoplasms of various organs. The characteristic neoplasms associated with von Hippel-Lindau are hemangioblastoma of the central nervous system and retina, clear cell renal cell carcinoma, and pheochromocytoma, but other lesions are well recognized. Pancreatic lesions, both primary and metastatic, are common, and several differential diagnostic possibilities must be considered.

Abstract
Papillary cystadenoma is a rare benign neoplasm of the epididymis, occurring mainly in young adult males. More than one-third of the cases reported in the literature have occurred in patients with von Hippel-Lindau disease. Conversely, epididymal nodules presumed to be papillary cystadenomas are found in one-third of males with von Hippel-Lindau disease. The association is stronger for bilateral tumors. The pathogenesis involves loss of the von Hippel-Lindau gene resulting in overexpression of the angiogenic protein "hypoxia-inducible factor." Papillary cystadenoma is of mesonephric derivation. It originates in the efferent ductules of the head of the epididymis in the form of tiny precursor lesions. Histologically, papillary cystadenoma is characterized by cystic spaces with intracystic papillary projections lined by clear cells, with a resultant resemblance to renal cell carcinoma. Immunohistochemical markers may facilitate the distinction between the 2 tumors. Treatment consists of surgical excision and the prognosis is excellent.

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
To determine the effectiveness of stereotactic radiosurgery (SRS) treatment to central nervous system (CNS) hemangioblastomas in von Hippel-Lindau disease (VHL), we analyzed long-term results in VHL patients treated with SRS. Patients were enrolled in a prospective VHL natural history study, undergoing SRS treatment of CNS hemangioblastomas. Treatment regimens, serial clinical evaluations, and longitudinal imaging data were analyzed. Twenty VHL patients (10 males and 10 females) underwent SRS treatment of 44 CNS hemangioblastomas (39 cerebellar and 5 brainstem). Mean (+/-SD) age at treatment was 37.5 +/- 12.0 years (range: 13-67). Mean follow-up was 8.5 +/- 3.2 years (range: 3.0-17.6 years). All patients were alive at last follow-up. Mean treated tumor volume was 0.5 +/- 0.7 cm(3) (range: 0.01-3.6 cm(3)). Mean prescription dose was 18.9 Gy (range: 12-24 Gy) at the tumor margin. Local control rate at 2, 5, 10, and 15 years after SRS treatment was 91%, 83%, 61%, and 51%, respectively. Univariate analysis did not identify variables associated (P > .05) with worse tumor control at last follow-up. Thirty-three percent of SRS-treated small (<1.0 cm diameter), asymptomatic tumors progressed over a long-term follow-up. There were no long-term adverse radiation effects. Although SRS treatment of hemangioblastomas in VHL has a low risk for adverse radiation effects, it is associated with diminishing control over a long-term follow-up. These results indicate that SRS should not be used to prophylactically treat asymptomatic tumors and should be reserved for the treatment of tumors that are not surgically resectable.

Abstract
OBJETIVO: descrever uma experiência e as técnicas para abordagem destas lesões com ênfase nos aspectos microcirúrgicos. MÉTODOS: foram relatados nove casos consecutivos de pacientes submetidos à ressecção de lesões intramedulares operados entre 2000 e 2008. A escala funcional de McCormick foi usada para avaliar o status funcional dos pacientes RESULTADOS: a idade dos pacientes variou de 13 a 45 anos (média de 27,1 anos). Quatro (44,4%) pacientes eram homens e cinco (55,5%), mulheres. Dois pacientes tinham a doença de von Hippel-Lindau, com outros hemangioblastomas associados. Conforme a localização, sete (77,7%) pacientes tinham lesões na região cervical (dois deles com tumores na transição crânio-cervical) e dois (22,2%) tinham lesões na região torácica. Todos os pacientes tiveram ressecção total das lesões, sendo que três apresentaram leve piora clínica no pós-operatório imediato. Após seis meses do procedimento cirúrgico, dois pacientes apresentaram melhora clínica, enquanto sete mantinham-se funcionalmente iguais ao período pré-operatório. CONCLUSÕES: o conhecimento anatômico e de técnicas microcirúrgicas adequadas permite a ressecação total destas lesões sem agregar morbidade adicional.
