摘要
目的:分析儿童常见腹膜、网膜和肠系膜实体肿瘤的CT表现,以提高对该部位实体肿瘤的认识。方法:回顾性分析2006年6月至2015年8月经CT诊断的儿童腹膜、网膜和肠系膜实体肿瘤共36例,包括炎性肌纤维母细胞瘤(IMT)5例,Castleman病(CD)6例,淋巴管畸形(LM)9例,Burkitt淋巴瘤11例,横纹肌肉瘤(RS)5例。分析这5种实体肿瘤的临床资料和影像学表现,总结影像学特征。结果:(1)5例IMT,1例位于胰腺尾部后方,4例位于腹腔内腹膜、网膜和肠系膜根部。增强后5例肿块的实质性部分均呈逐渐强化。(2)6例CD,3例位于腹腔内肠系膜间隙,1例位于小网膜囊,2例位于脊柱前方、后腹膜大血管周围。5例为单发,1例为多发。增强后6例均为均匀强化,其中2例增强后边缘有条状明显强化。(3)9例LM,3例位于左下腹与盆腔入口处,2例位于右下腹,4例占据大部分腹腔及盆腔,增强后肿块中央分隔有强化。(4)Burkitt淋巴瘤11例,6例为腹、盆腔弥漫性肿块,侵犯肠壁及系膜,1例表现为右腹部及盆腔2个肿块,1例表现为肝门及下腹部2个肿块,3例表现为腹腔内单一肿块。增强后均呈轻度明显不均匀强化。(5)5例RS,3例为腹腔至盆腔的巨大肿块,2例为盆腔内肿块。增强后均呈明显不均匀强化。结论:儿童腹膜、网膜和肠系膜来源的实体肿瘤相对成人少见,年长儿童与幼儿发生的肿瘤种类又有明显不同。CT能较好地提示该部位肿瘤的影像学特征。了解这几种常见肿瘤的影像学表现,能为诊断和鉴别诊断提供方便,同时对病人的治疗提供更好的建议。
Purpose： To analyze the incidence and CT manifestations of solid tumors of the peritoneum, omentum, and mesentery in children for further recognizing this disease. Methods： We retrospectively reviewed 36 cases, which were diagnosed as solid tumors of the peritoneum, omentum, and mesentery in our hospital between June 2006 and August 2015. These 36 cases included 5 inflammatory myofibroblastic tumors, 6 Castleman diseases, 9 lymphatic malformations, 11 Burkitt lymphomas and 5 rhabdomyosareomas. We summarized the imaging features of these 36 cases. Results： （1） Of 5 inflammatory myofibroblastic tumors, 1 was behind the pancreatic tail, 4 was located at the root of mesentery, the solid parts of these 5 tumors were enhanced gradually. （2） Of 6 Castleman diseases, 3 were located at abdominal cavity, 1 was located at omental bursa, 2 were located around the retroperitoneal vessels; 5 were single masses, 1 was with multiple masses. All 6 cases were with homogeneous enhancement, 2 of them were enhanced obviously at the margin of the masses. （3） Of 9 lymphatic malformations, 3 were located at left lower quadrant, 2 were located at right lower quadrant, and 4 occupied most abdomen and pelvis. The masses were with no enhancement except the septum. （4） Of 11Burkitt lymphomas, 6 were presented as abdominal and pelvic large masses which affected bowel walls and mesentery, 2 were with 2 masses each （1 was with right abdominal mass and pelvic mass, and 1 was with hepatic portal mass and lower abdominal mass）, 3 were presented as single masses. All cases were with enhancement. （5） Of 6 rhabdomyosarcomas, 3 were with abdominal and pelvic large masses, 2 were with bladder masses. All cases were with heterogeneous enhancement. Conclusion： Peritoneal solid tumors are far less common in children than that in adults. The histologic spectrums of the neoplasms in young children are differing from those in older patients. Knowledge of the spectrums of this disease allows the radiologist to provide an appropriate differential diagnosis and suggest proper patient freatment.
