The CT Findings of Pediatric Retroperitoneal Masses

报告儿童后腹膜常见与不常见占位病变的ＣＴ表现。材料和方法：对３４例（３２例经病理证实，２例随访复查证实）儿童后腹膜肿块病例完整的临床及ＣＴ检查资料进行分析。结果：本组儿童后腹膜占位病变共有１１种，以肾上腺瘤和后腹膜神经母细胞瘤最常见，畸胎瘤和肾胚胎瘤、新生儿肾上腺出血其次，肾上腺皮质癌较少见，罕见的有横纹肌肉瘤和血管外皮瘤。临床和ＣＴ特点各有其不同。结论：临床特点与ＣＴ表现相结合，极大部分儿童后腹膜肿块可作出明确诊断。

Materials and Methods: A complete analysis of 34 cases (32 proved pathologically, 2 confrimed by follow up) of pediatric retroperitoneal mass lesions was evaluated by CT scans and clinical correlations. Results: There were 11 kinds of pediatric retroperitoneal space occupying lesions including in this treatise.Adrenal tumors and retroperitoneal neuroblastomas seemed to be the most commonly seen, teratomas and renal embryomas were the next and followed by adrenal cortical carcinomas.Rhabdomyosarcomas and hemangiopericytomas even more rarely seen.
