海绵状血管瘤是肝脏最常见的良性肿瘤。18例患者进行了研究，计算机断层扫描（CT）和血管造影。血管造影特征是典型的，包括正常的肝动脉，没有肿瘤血管，和密集染色的充满血液的空间产生一个“棉絮”的外观。增强前，CT扫描显示大致球形、边界清楚的低密度肿块;增强后，周围有一个强化区，其厚度不等，有时内缘呈波纹状，但中心仍为低密度，病变的总体大小没有改变。作者认为，CT表现具有特征性，在某些情况下，血管造影是不必要的。
Cavernous hemangioma is the most common benign tumor of the liver. Eighteen patients were studied by both computed tomography (CT) and angiography. The angiographic features were classic, consisting of normal hepatic arteries, no tumor vessels, and densely stained blood-filled spaces producing a "cotton-wool" appearance. Before contrast infusion, CT scans showed roughly spherical, well-demarcated low-density masses; afterward there was a peripheral zone of enhancement which varied in thickness and sometimes had a corrugated inner margin, though the center remained low in density and the overall size of the lesion did not change. The authors feel that the CT findings are characteristic and that in some cases angiography is unnecessary.
