Hypopyon Uveitis as a Manifestation of Primary Choroidal Lymphoma.

ABSTRACT

A 78-year-old female was referred to our hospital due to a decrease of visual acuity in her left eye. On examination, presence of left choroidal folds and subretinal fluid was disclosed. After being misdiagnosed as neovascular age-related macular degeneration treatment with intravitreal injections of Aflibercept was started. Despite improvement of fluid, persistence of choroidal folds encouraged a magnetic resonance imaging revealing a left retrobulbar nodular lesion. Furthermore, development of hypopyon during follow-up allowed a flow cytometry analysis of an aqueous humour sample that confirmed infiltration by a non-Hodgkin mature B-cell lymphoproliferative process. Finally, treatment with Rituximab and intravenous corticosteroids achieved complete resolution. Primary choroidal lymphoma may occur with an atypical presentation, including hypopyon uveitis. Thus, familiarity with its clinical features is fundamental for an early recognition and correct management.
