| 摘 要： | 目的：探讨动态增强CT对肝癌自发破裂伴腹腔内出血型(血腹)的诊断价值。材料与方祛：回顾性分析10例肝癌发生破裂平扫十增强CT表现；分析肝癌破裂的增强CT特征。结果：所有的破裂的肿瘤均位于肝脏的周边带，6例显示了突出于肝边界外的实质。中心坏死7例，肝表面不连续5例。3例‘未发现破裂’的肝癌在增强时发现造影剂外溢至肝边界之外。2例只显示为肿块中出血但手术中发现己发生了破裂。1例整个肝脏破裂，分离的碎块漂浮于大量的腹水中。增强扫描后5例显示了周边带状强化及不连续低密度病灶。结论：增强CT使病灶显示更为清楚，能提高肝癌自发破裂诊断精确度，对临床怀疑肝癌自发破裂造成血性腹水者，增强CT检查十分必要。

| Abstract: | Objective: to assess the value of dynamic enhanced CT in detecting spontaneous hepatocarcinoma rupture as well as to assess CT features of hepatocarcinoma rupture. Materials and Methods: CT findings of hepatocarcinoma rupture in 10 cases proved surgically and pathologically were reviewed. CT characters of variable pathological changes of ruptured hepatocarcinoma were analyzed. The analysis involved the status of liver cirrhosis, ascites, intrahepatic locations of the tumor, extent of extrahepatic protrusion and central necrosis of the tumor. Result:All ruptured tumours were located at the periphery of the liver, 6 cases had a protruding contour. The maximum diameter of tumours ranged from 2 to 16cm. Discontinuity of the hepatic surface was seen in 5 cases, necrosis of core was seen in 7 cas4es. 3cases with non-ruptured masses also showed contrast medium flow over the perihepatic border during the arterial phase. 2 cases showed a haematoma with attenuated rim inside the mass, but rupture was found during surgery. 1 case show detached broken bits drifting in mass ascites. In five cases, CT images during the arterial phase showed a non-enhancing low attenuating lesion with focal discontinuity and peripheral rim enhancement. Conclusion : Enhanced CT can raise the diagnostic accuracy of hepatocarcinoma rupture; it should be taken in those patients suspected of hepatocarcinoma rupture by clinical findings. |
