【摘要】 目的 观察CT鉴别儿童囊实性肝脏间叶性错构瘤(HMH)与肝脏未分化胚胎性肉瘤(UESL)的价值。方法 回顾性分析经手术病理证实的25例HMH(HMH组)及15例UESL(UESL组)患儿的临床及腹部CT资料，比较两组间患儿一般资料及病灶CT表现的差异。结果 HMH组及UESL组病灶均单发。2组患儿年龄、血清甲胎蛋白阳性(>20μg/L)占比及病灶最大径、出血、病灶内囊腔数量、囊腔形态、囊腔内壁光滑与否、增强动脉期病灶内见血管与否差异均有统计学意义(P均<0.05)。结论 CT可用于鉴别诊断儿童囊实性HMH与UESL。更多还原

【Abstract】 Objective To observe the value of CT for differential diagnosis of cystic-solid hepatic mesenchymal hamartoma(HMH) and undifferentiated embryonal sarcoma of the liver(UESL) in children. Methods Clinical and abdominal CT data of 25 children with HMH(HMH group) and 15 children with UESL(UESL group) confirmed by postoperative pathology were retrospectively analyzed, and the general data and CT findings of lesions were compared between groups. Results Both HMH and UESL present as single lesion. Significant difference of age and positive(>20 μg/L) proportion of serum alpha fetoprotein, the maximum focal diameter of lesion, hemorrhage, numbers and shape of cysts, whether smooth of the inner wall of the cyst and presence of blood vessels in lesions during arterial phase enhanced CT or not were found between groups(all P<0.05). Conclusion CT could be used for differential diagnosis of cystic-solid HMH and UESL in children.更多还原
