So, based on the fundus appearance, locationof the lesion and echography results, this patient has a choroidal hemangiomawith an overlying neurosensory retinal detachment. Choroidal hemangioma, or cavernous hemangioma of the choroid, is a benign,developmental tumor that can appear in isolation or associated with Sturge-Webersyndrome. Ourpatient had an isolated choroidal hemangioma. These vascular tumors are composed mostly of large, dilated, thin-walledvessels with minimal stroma. They blend almost imperceptibly with the surroundingchoroidal tissue.
Choroidal hemangiomas are usually round or oval, slightlyelevated, with a subtle orange-red color.
Often they have indistinct borders. Usually they are most apparent with binocular indirect ophthalmoscopy. Typically you ll see choroidal hemangiomas in the posterior pole, mostoften within the paramacular area. Some may appear adjacent to the opticnerve or on the nasal side of the disc. Most patients are asymptomatic, which means you usually discover theselesions incidentally.
