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.
静脉血管瘤是一种罕见的中枢神经系统血管异常。从病理学上看，它类似于动静脉畸形，但血管变化仅见于静脉。在本病例中，动态放射性核素检查比静态检查能更好地显示病变。在计算机动态研究中，病变部位的循环时间与对侧半球对称区域的循环时间相比明显延长。病变区域的时间-活性曲线峰值也比对侧对称区域出现得更晚。因此，计算机伽马相机的应用有助于静脉血管瘤的诊断，且该方法似乎具有一定的鉴别诊断潜力。
