Superior sagittal sinus thrombosis, documented by cerebral angiography, was
demonstrated by indium-111 platelet scintigraphy in a 40-year-old man
presenting with seizures and intracerebral hematoma. Early scintigraphy
demonstrated focal increased indium-111 activity at the two ends of the
thrombus, while later scintigraphy showed diffuse increased activity in the
area of the sinus. This initial experience suggests that platelet
scintigraphy may provide unique information regarding the natural history
of intracranial venous thrombosis.
