von Hippel-Lindau disease manifesting as a chiasmal syndrome.

A 21-year-old woman presented with a two year history of progressive loss of vision in the left eye. Brain MRI revealed a supresellar mass felt to be most consistent with a meningioma. However, pathologic examination including special stains disclosed features characteristic of hemangioblastoma. Further evaluation established the diagnosis of von Hippel-Lindau disease by demonstrating retinal capillary hemangiomas, small renal and hepatic cysts, and cervico-medullary masses later confirmed to be hemangioblastomas. To date, no other family members have displayed features of this inherited syndrome.
