title: Orbital lymphoma presenting with choroidal detachments.
abstract: This report describes a case of orbital B-cell lymphoma of extranodal marginal cell type with atypical clinical and radiographic features. This patient presented with choroidal effusion and optic disk swelling of the right eye. A CT scan revealed an intraconal mass surrounding the optic nerve and indenting the globe. A right orbitotomy with biopsy of the mass was performed. Histologic and immunohistochemical analysis confirmed a diagnosis of extranodal marginal zone B-cell lymphoma. This is the first case of primary orbital lymphoma presenting with choroidal effusion described in the literature.
