Bilateral papilledema with retinal hemorrhages in association with cerebral venous sinus thrombosis and paroxysmal nocturnal hemoglobinuria.
Eye Department, Kaplan Hospital, Rehovot, Israel.
PURPOSE: To report a patient with paroxysmal nocturnal hemoglobinuria who complained of transient obscurations of vision and exhibited bilateral papilledema with retinal hemorrhages. METHODS: Case report. Computed tomography did not demonstrate any abnormality but magnetic resonance imaging disclosed signs of cerebral venous sinus thrombosis. RESULTS: The patient was treated with subcutaneous low molecular weight heparin and intravenous corticosteroids. Symptoms improved within one week and ophthalmoscopic signs resolved within four months. CONCLUSION: Bilateral papilledema with extensive retinal hemorrhages may be a sign of cerebral venous sinus thrombosis, a reported devastating complication of paroxysmal nocturnal hemoglobinuria. Thus, any patient with suspected cerebral venous sinus thrombosis should undergo magnetic resonance imaging, even when results of computed tomography are normal.
