目的：研究腹膜后神经母细胞瘤的CT表现。材料与方法：本组经临床病理证实腹膜后神经母细胞瘤13例，男9例，女4例，平均年龄3．65岁，平均就诊时间38．2天。其中发生于肾上腺7例，腹膜后6例。13例均进行了CT检查。结果：13例均为单发，12／13例直径＞5cm，均是给节状或不规则，CT密度低于肝组织，11例伴囊变，11例见不同程度钙化，12例侵犯周围组织，6例淋巴结转移，8例远隔器官转移。结论：发生于儿童肾上腺或腹膜后的巨大肿瘤，伴有囊变及钙化者应考虑本病诊断。
Objective: To study the CT manifestations of retroperitoneal neuroblastoma. Materials and Methods: The group of 13 cases of retroperitoneal neuroblastoma confirmed by clinicopathology, 9 males and 4 females, the average age of 3.65 years, with an average consultation time of 38.2 days. Occurred in 7 cases of adrenal gland, retroperitoneal 6 cases. Thirteen patients underwent CT examination. Results: Thirteen patients were all single, 12 of 13 patients were> 5 cm in diameter. All of them were nodular or irregular. CT density was lower than that of hepatic tissue. Eleven patients had cystic degeneration. Eleven patients had varying degrees of calcification and 12 patients invading around Tissue, 6 cases of lymph node metastasis, 8 cases of distant organ metastasis. CONCLUSIONS: The huge tumors that occur in the adrenal or retroperitoneum of children, with cystic and calcification, should be considered in the diagnosis of this disease.
