摘要
目的观察腹膜后不同类型神经源性肿瘤的CT表现。方法回顾性分析34例术前接受CT平扫和增强检查、术后病理确诊的神经源性肿瘤的CT表现,探讨不同类型肿瘤的影像学特征。结果 34例肿瘤中,CT示肾上腺区25例,肾上腺区外9例;14例肿瘤呈分叶状,其中恶性肿瘤3例;20例肿瘤呈类球形,其中恶性肿瘤4例。7例肿瘤内部见钙化,包括4例成神经细胞瘤和3例节细胞瘤,成神经细胞瘤呈粗大钙化,而节细胞瘤呈细小点状钙化。结论腹膜后不同类型神经源性肿瘤的CT表现具有一定特征性,结合患者年龄及临床表现可以做出准确诊断。
Objective To analyze CT appearances of retroperitoneal neurogenic tumors. Methods Totally 34 patients with neurogenic tumors confirmed by surgical pathology underwent plain and contrast enhance CT scanning before opera- tion. CT findings were analyzed. Results Among 34 cases, tumors located in adrenal gland area in 25 patients, while out of the adrenal gland area in 9 patients. Three malignant tumors were found in 14 lobulated tumors, and 4 malignant tumors were found in 20 round tumors. Calcifications were detected in 7 cases, including 4 neuroblastomas and 3 ganglioneuromas. Irregular calcifications were found in neuroblastomas, and tiny calcifications were found in ganglioneuromas. Conclusion CT findings of retroperitoneal neurogenic tumors show some definite characteristics, which contribute to correct diagnosis combined with the age and clinical manifestations.
