A retrospective, multi-institutional study was carried out on a series of 50 histologically proved benign hepatic tumors. The 27 hepatic adenomas (HAs) and 23 cases of focal nodular hyperplasia (FNH) were studied with ultrasonography (US) and dynamic computed tomography (CT). Angiography was performed in 26 cases (15 HAs, 11 FNHs); scintigraphy was not used because of its cost. US scans proved nonspecific. CT scans demonstrated hemorrhage in five HAs and were useful in characterizing tumoral vascularity and any intratumoral features such as necrosis or central fibrous scar. The presence of arterial vessels (five patients) in the projection of this central fibrous scar is suggestive of FNH. Dynamic CT scans did not show the type of tumor in most cases. In cases with lesions greater than 3 cm for which doubt as to the diagnosis persists, combined use of morphologic data, scintigraphy, dynamic CT scanning, and angiography can guide the therapeutic decision: surgery or follow-up CT study after use of oral contraceptives is stopped.
对一系列50例经组织学证实的良性肝肿瘤进行了一项回顾性多机构研究。对27例肝腺瘤（HA）和23例局灶性结节性增生（FNH）进行了超声检查（US）和动态计算机断层扫描（CT）。26例（15例HA，11例FNH）进行了血管造影；由于成本原因未使用闪烁扫描。超声扫描结果无特异性。CT扫描显示5例HA有出血，有助于描述肿瘤血管情况以及任何肿瘤内特征，如坏死或中央纤维瘢痕。在该中央纤维瘢痕投影区域出现动脉血管（5例患者）提示为FNH。动态CT扫描在大多数情况下无法显示肿瘤类型。对于病变大于3 cm且诊断仍存疑问的病例，综合形态学数据、闪烁扫描、动态CT扫描和血管造影可指导治疗决策：手术或在停用口服避孕药后进行CT随访研究。
