目的探讨肝脏炎性假瘤的CT表现特征,并结合鉴别诊断分析误诊原因,提高本病的影像学诊断。方法对收集的17例肝脏炎性假瘤进行回顾性分析。结果 15例为单发肿块,2例呈多发病灶。CT平扫14例表现为低密度,3例为稍高密度。动态增强扫描5例动、门脉期及延迟期均无强化。8例动、门脉期及延迟期病灶边缘呈环状强化,其中4例内部有分隔状强化;4例动、门脉期无强化,延迟期呈结节状强化。有7例误诊,CT诊断正确率约59%。结论较多的肝脏炎性假瘤通过其CT表现,综合分析能够正确诊断。
Objective To investigate the CT features of inflammatory pseudotumor in liver and to analyze the causes of misdiagnosis by differential diagnosis and to improve the imaging diagnosis of this disease. Methods 17 cases of hepatic inflammatory pseudotumor collected from our hospital were retrospectively analyzed. Results 15 cases of single mass, 2 cases were multiple lesions. CT scan showed 14 cases of low density, 3 cases were slightly higher density. Dynamic enhanced scan in 5 cases of dynamic, portal phase and delayed phase were no enhancement. 8 cases of moving, portal vein and delayed edge of the lesion was ring-shaped enhancement, including 4 cases of internal enhancement; 4 cases of dynamic portal phase without enhancement, delayed nodular enhancement. There were 7 cases misdiagnosed, the correct rate of CT diagnosis was about 59%. Conclusions More hepatic inflammatory pseudotumor can be correctly diagnosed by comprehensive analysis of CT findings.
