The occurrence of retroperitoneal schwannoma is uncommon and its presence may only be expressed by insidious onset of nonspecific symptoms such as vague abdominal pain. Imaging modalities like computed tomography and magnetic resonance imaging may demonstrate the tumor, but due to heterogeneity and degeneration in some tumors, it may mimic malignancy. So, fine needle aspiration cytology followed by tissue sampling through needle biopsies may be essential to confirm the diagnosis prior to the surgery. This case is reported for its rare clinical presentation, having duration of more than 40 years with cystic degenerative changes.
腹膜后神经鞘瘤的发生并不常见，其存在可能仅表现为隐匿起病的非特异性症状，如模糊的腹痛。计算机断层扫描和磁共振成像等影像学检查可能显示肿瘤，但由于一些肿瘤的异质性和变性，它可能类似恶性肿瘤。因此，在手术前，细针穿刺细胞学检查随后通过针吸活检进行组织采样对于确诊可能至关重要。本文报道该病例因其罕见的临床表现，病程超过40年且伴有囊性退变。
