目的 探讨腹膜后神经母细胞瘤影像表现 :方法 回顾分析经手术、病理及临床证实 36例。男 2 0例 ,女 16例。年龄 3月～ 5 812 岁。腹部CT和B超检查 36例。腹部平片 2 3例。胃肠道造影 4例。结果 (1)CT显示腹膜后实质性肿块 ,内有出血、坏死、钙化 31例。 5例为软组织肿块。 (2 )B超探及腹膜后回声增强 2 8例。界限清 8例 ,不清 2 0例。 (3)腹部平片显示软组织肿块2 3例。 (4)胃肠道造影 4例均显示为内脏受压。结论 B超、平片 :胃肠道造影提示腹腔肿块。CT显示腹膜后实质性肿块伴出血、坏死、钙化 ,应考虑本病诊断。
Objective To explore the imaging features of retroperitoneal neuroblastoma:Methods Retrospective analysis of 36 cases confirmed by surgery, pathology and clinical. There were 20 males and 16 females. Age March to 5 812 years old. Abdominal CT and B-ultrasound in 36 cases. Abdominal plain film 23 cases. Gastrointestinal angiography in 4 cases. Results (1) CT showed a solid retroperitoneal mass with hemorrhage, necrosis and calcification in 31 cases. Five cases were soft tissue lumps. (2) B ultrasound exploration and retroperitoneal echo enhancement in 28 cases. The boundary was clear in 8 cases, and 20 cases were unclear. (3) Abdominal plain films showed soft tissue mass in 23 cases. (4) Gastrointestinal angiography showed visceral compression in 4 cases. Conclusion B-ultrasound and plain film: GI imaging prompted abdominal mass. CT shows a solid retroperitoneal mass with hemorrhage, necrosis, and calcification. The diagnosis of this disease should be considered.
