【摘要】：目的 :探讨小儿肝间叶性错构瘤的CT及MR表现,以提高对于该病的诊断水平。方法 :回顾性分析2008年10月—2012年8月10例经病理证实的肝间叶性错构瘤患儿的CT及MR资料。10例患儿中,男4例,女6例,年龄11~60月,平均(27.0±14.54)月,主要症状:腹部包块5例,腹痛5例,其中2例患儿AFP轻度升高,10例患儿分别行CT增强或MR平扫扫描。结果:10例病例中,病灶位于肝右叶5例,肝左叶3例,同时累及肝左、右叶2例,病灶直径8.1~17.8 cm,平均(13.26±3.18)cm。CT表现主要取决于病变囊实性成分比例,表现为囊实混合型7例、实性型3例,增强后肿瘤实性部分及分隔强化,囊性部分无强化。MR检查中,其实性部分T1、T2序列呈稍低信号,囊性部分T2呈高信号。结论:肝间叶性错构瘤的CT及MR表现有一定特征性,结合其临床特征并注意与肝脏其他囊实性肿瘤相鉴别,术前大多能做出正确的诊断。
[Abstract]:Objective: to investigate the CT and MR findings of mesenchymal hamartoma in children. Methods: the data of CT and MR in 10 children with interhepatic hamartoma confirmed by pathology from October 2008 to August 2012 were retrospectively analyzed. There were 4 males and 6 females, aged from 11 to 60 months with an average of (27.0 卤14.54) months. The main symptoms were abdominal mass in 5 cases. Of the 5 cases of abdominal pain, 2 cases had mild elevation of AFP and 10 cases underwent CT enhancement or MR plain scan. Results in 10 cases, the lesions were located in the right lobe of liver in 5 cases, Zuo Ye in 3 cases, and involved the left and right lobes of the liver in 2 cases. The mean (13.26 卤3.18) cm, of the lesion diameter was (13.26 卤3.18) cm.CT, which was mainly determined by the proportion of the cystic and solid components of the lesion. There were 3 cases of solid type with solid and septal enhancement after enhancement. In the cystic part without enhancement, the T 1 T 2 sequence of the cystic part was slightly low signal intensity, and the cystic part T 2 showed high signal intensity. Conclusion: the CT and MR findings of mesenchymal hamartoma have some characteristics. Combined with their clinical features and differential diagnosis from other cystic and solid tumors of liver, most of them can be correctly diagnosed before operation.
