摘要
目的：提高对肝脏间叶性错构瘤（MHL）的临床及其CT表现的认识。方法：回顾性分析我院2005年1月—2011年6月有完整临床资料和CT平扫与增强检查的5例MHL。证实手段为术后病理结果。结果：5例MHL患儿中，男3例，女2例。均为单发病灶，其中4例位于肝右叶，1例位于肝左叶。病灶最大直径为16.6 cm×11.9 cm，最小直径为5.1 cm×4.1 cm。CT平扫表现为肝内多房囊实性病变，增强后分隔处可见强化，低密度囊腔内未见明显强化。结论：MHL是一种罕见的肝脏良性肿瘤，CT检查作为其术前主要诊断手段有一定的特征性，多数表现为肝右叶巨大多房囊实性肿块，增强后分隔处可见强化。确诊依靠病理诊断。
Abstract
Objective: To improve the awareness of the CT appearances and clinical presentations of mesenchymal hamartoma of the liver(MHL). Methods: Clinical data, pre- and post-enhanced CT images of 5 cases of MHL were retrospectively reviewed from January 2005 to June 2011 in our hospital. Results: In these 5 cases, there were 3 boys and 2 girls. All of the lesions were solitary, with 4 in the right lobe and one in the left lobe. The biggest size of the mass was 16.6 cm×11.9 cm, while the smallest size was 5.1 cm×4.1 cm. Pre-enhanced CT scan showed the mass was a mixture of cysts cavities and solid septations. Post-enhanced CT scan showed an increased enhancement of the septa, while the cysts had no enhancement. Conclusion: Mesenchymal hamartoma is a kind of rare benign tumors which arise from liver in children. As its main imaging study method, CT scan has some specific features: Pre-enhanced CT scan shows a mixed mass which usually locates in right lobe, while post-enhanced CT scan shows an enhancement of the septa. Pathological examination is necessary for the final results.
