An Incidental Retinal Hemangioblastoma in a case of Central Serous Chorioretinopathy

Retinal hemangioblastoma (capillary hemangioma) is a benign vascular tumor of the retina or optic nerve head. It can be sporadic or associated with von Hippel-Lindau (VHL) disease. Three distinct forms of juxta papillary capillary hemangioblastomas have been described, including exophytic, endophytic, and sessile forms. An endophytic tumor appears as an orange-red lesion. However, exophytic and sessile forms are difficult to diagnose as they do not have the characteristic appearance of hemangioblastoma. They are misdiagnosed as papillitis, unilateral papilledema, choroidal hemangioma, choroiditis, or choroidal neovascularization. We report a case of incidentally detected juxta papillary hemangioblastoma on fundus fluorescein angiography (FFA) and optical coherence tomography angiography (OCTA) in a case of central serous chorioretinopathy (CSCR).
