隐匿性肝癌自发破裂出血的螺旋CT诊断

目的探讨隐匿性肝癌自发破裂出血的螺旋CT诊断价值。方法对6例经手术病理证实的隐匿性肝癌破裂出血病人的CT资料进行回顾性分析。结果平扫肝内呈混杂密度影，边界欠清晰，5例肝、脾周见液体密度影；增强扫描动脉期边缘可见不均匀强化，1例肿瘤可见包膜及裂口，5例密度不均匀，内可见多条裂隙；静脉期2例可见门静脉癌栓；造影剂渗漏均不明显。结论CT诊断隐匿性肝癌自发破裂出血有较高的价值，可作为首选检查方法；三期增强扫描十分必要，对于肝癌破裂的诊断具有较高的临床应用价值。

SPIRAL CT DIAGNOSIS OF OCCULT SPONTANEOUS RUPTURE OF LIVER CANCER

Objective To assess the diagnostic value of spiral CT for spontaneous rupture of liver cancer. Methods Retrospective review was clone for CT findings confirmed by surgery in six patients with spontaneous-rupture liver cancer. Results The findings of CT were; on plain scan, there was mix density inside the liver with obscure boundary, the liver and spleen were surrounded by liquid in five cases. Inhomogeneous enhanced tumor tissues were demonstrated at arterial phase. Capsula and cleft were seen in one case, and five with mix density. Embolus in portal vein was noted in two. No obvious leakage of contrast observed. Conclusion CT is of diagnostic value for spontaneous rupture in liver cancer, which is recommended as the first-choice examination. Three-phase enhancement scanning is important for its higher accuracy.
