Three cases of cavernous hemangioma of the liver having atypical imaging features are described. In the first case, an 11 x 10 cm hypervascular mass with a central hypovascular area supplied by many large tortuous vessels was demonstrated on angiography, CT, and sonography. The mass had a central cavity that contained fluid. In the second case there was a 2-cm isoechoic mass with a peripheral halo, despite the presence of typical features of hemangioma on angiography. The halo was shown histologically to be fibrous tissue surrounding the tumor. In the third case, a 6.5 x 4.3 cm mass exhibited slight peripheral enhancement on CT but was not detectable by angiography. Histologically, the tumor was hyalinized with only scattered small foci of hemangioma within it.
本文描述了三例具有非典型影像学特征的肝脏海绵状血管瘤。第一例，血管造影、CT和超声检查显示一个11×10cm的高血管性肿块，中央为低血管区，由许多粗大迂曲的血管供血。肿块有一个含液体的中央腔。第二例，尽管血管造影显示有血管瘤的典型特征，但有一个2cm的等回声肿块，周边有晕环。组织学检查显示晕环为肿瘤周围的纤维组织。第三例，一个6.5×4.3cm的肿块在CT上表现为轻微的周边强化，但血管造影未检测到。组织学检查显示肿瘤已玻璃样变，内部仅有散在的小灶性血管瘤。
