【摘要】：目的观察儿童肝脏间叶错构瘤(HMH)的CT影像学特点。方法收集经术后病理证实的19例HMH患儿,术前均行CT检查,回顾性分析其临床及CT影像学特征。根据CT平扫图像显示的病变密度,将瘤灶分囊性、囊实性、实性3种类型。结果 19例HMH病灶均为巨大类圆形或长椭圆形,肿瘤最大径4~23cm,CT定位诊断准确率为78.95%(15/19)。CT平扫12例表现为囊实性,4例为单纯实性,3例为多分隔囊性占位。1例囊实性占位内见点状钙化。增强后囊性成分无强化,实性成分轻、中度不均匀性强化。7例(3例囊实性和4例实性)病灶内见肝血管分支穿行。结论HMH的CT平扫可表现为多分隔囊性、囊实性和实性,瘤灶实性成分强化模式多样。
[Abstract]:Objective to observe the CT features of hepatic mesenchymal hamartoma (HMH) in children. Methods the clinical and CT features of 19 children with HMH confirmed by postoperative pathology were analyzed retrospectively. According to the density of CT scan, the lesions were classified into three types: cystic, solid and solid. Results all of the 19 HMH lesions were large round or long oval. The accuracy of CT localization of the tumor was 423 cm ~ (-1). Plain scan of 78.95%(15/19).CT was performed in 12 cases with cystic solid lesions in 4 cases, simple solid lesions in 3 cases, multiple septal cystic mass in .1 cases with punctate calcification in 1 cases. After enhancement, no enhancement of cystic components, mild and moderate heterogeneous enhancement of solid components were observed in 7 cases, 3 cases with cystic and 4 cases with solid. Conclusion CT plain scan of HMH can show multiple divisional cystic, solid and solid, and multiple enhancement modes of solid components in tumor focus.
