Abstract
A 69-year-old man complained of mild headache and abnormal visual fields in both eyes. Two months after the onset of these symptoms, the patient exhibited good central vision, abnormal visual fields, and papilledema. Enhanced computed tomography and magnetic resonance angiography of the brain showed no abnormality. Neurologic study showed no localizing signs, but increased intracranial pressure with normal composition of the cerebrospinal fluid. Digital subtraction angiography revealed thrombosis of the superior sagittal sinus. The patient was treated with heparin and acetazolamide. Thereafter, his intracranial pressure and papilledema decreased. Ophthalmologists and neurosurgeons should be aware that old cerebral sinus thrombosis may require digital subtraction angiography for diagnosis.
