摘要
目的 探讨儿童腹部肌纤维母细胞瘤（IMT）的CT表现。方法 收集2008～2013年经病理证实的IMT患儿10例，术前均经CT平扫及增强检查，对照术后病理结果 并分析肿瘤的CT表现。结果 10例患儿均为单发病例，发病部位肠系膜3例，小网膜1例，肝脏1例，腹膜后2例，腹腔2例，乙状结肠1例。CT平扫表现为实性肿块8例，囊实混合性肿块2例。增强扫描显示实性部分均呈明显不均匀强化，动脉期无明显强化1例，其余9例患儿均呈明显不均匀强化。静脉期10例患儿均呈明显强化，强化后CT值均大于95 Hu，且呈逐渐强化的趋势。病理结果 显示肿瘤组织由梭形细胞组成。结论 小儿腹部IMT的CT表现有一定特点，能提供有价值的诊断信息。
Objective To investigate the CT features of abdominal inflammatory myofibroblastic tumor （IMT） of children. Methods Collect 10 children with IMT confirmed by the pathology from 2008 to 2013 was conducted CT non-contrast enhanced scan,comparing the pathological results after the operation and analyzing the CT features of tumor. Results 10 cases were all for single,including 3 in the mesenteries,1 in the lesser omentum,1 in the liver,2 in the retroperitoneum,2 in the abdominal cavity, 1 in the sigmoid colon. The CT non-contrast scan results showed 8 cases had solid-appearing mass and the other 2 cystic-solid mass. The enhanced scan showed an obvious uneven enhancement of solid parts ,1 case had no obvious enhancement in the arterial phase while the rest 9 were significantly strengthened ,all of the 10 cases were remarkably enhanced in the venous phase ,The enhanced CT values are more than 95 Hu and demonstrated a trend of gradual strengthening. The result showed in the pathology the tumor tissue is composed of spindle cells. Conclusion Because CT features of children′s ahdominal IMT have specific characters,which can provide some valued information for its diagnosis.
