Von Hippel-Lindau Disease

چکیده
A germline mutation in the Von-Hippel Lindau (VHL) gene predisposes carriers to development of abundantly vascularised tumours in the retina, cerebellum, spine, kidney, adrenal gland and pancreas. Most VHL patients die from the consequences of cerebellar haemangioblastoma or renal cell carcinoma. The VHL gene is a tumour suppressor gene and is involved in angiogenesis by regulation of the activity of hypoxia-inducible factor 1-alpha (HIF1-alpha). Clinical diagnosis of VHL can be confirmed by molecular genetic analysis of the VHL gene, which is informative in virtually all VHL families. A patient with (suspicion for) VHL is an indication for genetic counselling and periodical examination.

Unusual diagnosis of Von Hippel Lindau syndrome on PET/CT - Case report and brief review of literature
We report an unusual case of a young male with cerebellar hemangioblastoma treated previously for medullary carcinoma of thyroid, whose PET/CT scans revealed a constellation of findings that suggested the rare Von Hippel Lindau syndrome. The diagnosis was clinched by confirming the findings on whole body contrast enhanced computed tomography (CECT) and contrast enha...
متن کاملIndependent segregation of von Hippel-Lindau disease and cerebral cavernomas.
A probable diagnosis of von Hippel-Lindau disease was made in a two generation family in which the proband had a phaeochromocytoma, renal cysts, and multiple cerebral cavernomas. His sister had multiple similar cerebral vascular lesions and his father died from renal carcinoma aged 42. Although the family did not satisfy the conventional diagnostic criteria for von Hippel-Lindau disease, an und...

We describe five patients diagnosed with von Hippel-Lindau disease who complained of abdominal distension, pain and discomfort for a long time. All patients underwent ultrasonography, CT scan and MRI, which showed huge pancreas filled with multiple cysts. Additionally, extrapancreatic findings such as cerebellar hemangioblastoma (3 patients), retinal hemangioblastoma (2), renal cell carcinoma (...

Von Hippel-Lindau syndrome is an autosomal dominant disorder that includes susceptibility to hemangioblastomas of the eyes and central nervous system, renal clear cell carcinoma, multiple pancreatic cysts, serous cystadenomas and pancreatic neuroendocrine tumors, pheochromocytoma, endolymphatic sac tumors, and cystadenomas of the epididymis and broad ligament. We present a 16-year-old male who ...

Cerebellar haemangioblastomas are rare in the elderly. Those associated with the von Hippel-Lindau (VHL) disease, usually present during the third decade of life. We report an unusually delayed presentation in an 80 year old obligate carrier of VHL gene mutation.

OBJECTIVES Haemangioblastoma of the CNS occurs as a sporadic entity and as a manifestation of the autosomal dominant von Hippel-Lindau disease with the major additional components retinal angioma, renal cancer, and pheochromocytoma. Genetic testing for germline mutations predisposing to von Hippel-Lindau disease has been available since identification of the VHL tumour suppressor gene. The impa...
