Von Hippel-Lindau Disease (VHL)
Definition / Overview
Autosomal dominant tumor predisposition syndrome caused by mutations in the VHL gene (chromosome 3p25). Retinal capillary hemangioblastomas are often the earliest manifestation. Listed as a differential diagnosis for retinal-arterial-macroaneurysm.
Key Details
- Details to be added from dedicated source â genetics, systemic manifestations (CNS hemangioblastomas, renal cell carcinoma, pheochromocytoma), retinal features, screening, management
Clinical Relevance
Retinal capillary hemangioblastomas can present as vascular retinal lesions with exudation, potentially mimicking RAM. Distinguishing features include feeder vessel pattern, younger patient age, and systemic associations.
Associations
- retinal-arterial-macroaneurysm â differential diagnosis
- coats-disease â also in the vascular retinal lesion differential
