A patient with cavernous hemangiomas in the cerebellum, brain stem, retina, pancreas and liver most likely has which disease?

• A. Von Hippel-Lindau disease
• B. Sturge-Weber syndrome
• C. Tuberous sclerosis
• D. Osler-Weber-Rendu syndrome

Answer: (A)

Recognizing a hereditary tumor syndrome that causes multiple vascular tumors in the CNS, retina, and visceral organs. The combination of cavernous hemangiomas in the cerebellum and brainstem, retinal hemangioblastomas, and pancreatic and hepatic cystic/vascular lesions is characteristic of Von Hippel-Lindau disease. This disorder results from germline mutations in the VHL tumor suppressor gene, leading to loss of VHL function and stabilization of hypoxia-inducible factor. That drives overproduction of angiogenic factors like VEGF, promoting multiple highly vascular lesions throughout the CNS, retina, pancreas, and liver, and also increases risk for renal cell carcinoma and pheochromocytoma. Other conditions have different patterns: Sturge-Weber syndrome features facial port-wine stains and leptomeningeal angiomas with neurologic complications; tuberous sclerosis shows cortical tubers, subependymal nodules, and renal angiomyolipomas; Osler-Weber-Rendu syndrome presents with mucocutaneous telangiectasias and AV malformations.
