A case is reported here of an ancient schwannoma in the retroperitoneum. The findings of abdominal ultrasound and CT in a patient with a retroperitoneal ancient schwannoma are presented, and the clinical and radiological features of this unusual tumour are reviewed. The presence of a large, well-delineated complex cystic mass in the deep soft tissues should raise the possibility of an ancient schwannoma. It is important to recognize these tumours as benign with excellent prognosis so as to avoid unnecessary radical surgery.
本文报告一例腹膜后古老型神经鞘瘤病例。介绍了一名腹膜后古老型神经鞘瘤患者的腹部超声和CT检查结果，并对这种罕见肿瘤的临床和放射学特征进行了综述。深部软组织中出现边界清晰的巨大复杂囊性肿块应提高古老型神经鞘瘤的可能性。认识到这些肿瘤为良性且预后良好很重要，这样可以避免不必要的根治性手术。
