【摘要】 目的探讨肝脏血管平滑肌脂肪瘤的CT表现,以提高诊断正确率。方法收集经手术及病理证实的肝脏血管平滑肌脂肪瘤8例。全部病例均作上腹部CT平扫、增强动脉期及门脉期扫描,其中3例加病灶薄层扫描,2例加延迟期扫描。结果CT平扫8个病灶均呈低密度,动脉期所有病灶均有强化,门脉期5例病灶仍有持续强化;8例中5例病灶内有明显脂肪成分,3例含脂肪较少经薄层扫描显示脂肪成分。结论含脂肪较多的肝脏血管平滑肌脂肪瘤常有典型的CT表现,诊断容易;含脂肪较少的肝脏血管平滑肌脂肪瘤经薄层扫描能提高脂肪的检出率,从而能提高病变诊断的正确率。更多还原

【Abstract】 Objective In order to improve diagnosis of the disease, CT appearances of hepatic angiomyolipoma were studied. Methods 8 cases were proved by surgery and pathology. All cases were examined with plain CT scans and contrast arterial phase, portal venous phase, 3 cases of them were taken thin slice CT scans, 2 cases of them were scanned in delayed phase. Results 8 cases appeared as hypodense on plain CT scans and showed enhancement on the arterial phase,5 remained enhancement on portal venous phase;5 contained component of fat, Thin thickness scan showed the component of fat in anther 3 which contained less fat. Conclusions The hepatic angiomyolipoma with more fat has typical manifestations. It’s not difficult to diagnose. Thin thickness scan is valuable to find fat in tumors with less fat component, which can raise the diagnostic rate.更多还原
