title: Radionuclide diagnosis of venous angioma.
abstract: Venous angioma is a rare vascular anomaly of the central nervous system. Pathologically, it resembles arteriovenous malformation, but the vascular changes are seen only in the veins. In the present case, the lesion was seen better with dynamic rather than static radionuclide examination. In a computerized dynamic study, the circulation time in the lesion was significantly prolonged compared with the circulation time in the symmetrical area of the contralateral hemisphere. The peak of the time-activity curve also appeared later in the lesion area than in the symmetrical contralateral area. Thus the use of the computerized gamma camera is useful in the diagnosis of venous angioma and the method seems to have some differential diagnostic possibilities.
