Schwannoma in the retroperitoneal space is rare, and it is extremely rare in patients with no history of neurofibromatosis. We present a case of giant retroperitoneal schwannoma in a 52-year-old man who did not have neurofibromatosis. Because malignant transformation would be extremely rare in this circumstance, close imaging follow-up could avert the necessity for complete resection. The possibility of schwannoma should be considered when evaluating retroperitoneal tumors with the characteristic findings, even if there is no connection between the tumor and the intervertebral foramina.
腹膜后间隙的神经鞘瘤很罕见，在没有神经纤维瘤病病史的患者中极为罕见。我们报告一例52岁无神经纤维瘤病的男性巨大腹膜后神经鞘瘤病例。由于在这种情况下恶性转化极为罕见，密切的影像学随访可避免完全切除的必要性。即使肿瘤与椎间孔之间没有联系，在评估具有特征性表现的腹膜后肿瘤时也应考虑神经鞘瘤的可能性。
