Schwannomas are typically slow growing, encapsulated benign neoplasms. Visceral schwannomas are rare, and preoperative diagnosis is challenging, as they are often confused with other neoplasms even with advanced imaging studies. Surgical excision is usually needed to establish a definitive diagnosis, as pathology is the "gold standard." We review the imaging findings of abdominal schwannomas focusing on pancreatic, gastrointestinal, and retroperitoneal/adrenal schwannomas with pathology correlation. We conclude that schwannoma should be included in the broad differential diagnosis of an abdominal mass and that when it is unnecessary radical resection can be avoided.
神经鞘瘤通常生长缓慢，为包膜良性肿瘤。内脏神经鞘瘤较为罕见，术前诊断具有挑战性，因为即使进行了先进的影像学研究，它们也常与其他肿瘤混淆。通常需要通过手术切除来明确诊断，因为病理检查是“金标准”。我们回顾了腹部神经鞘瘤的影像学表现，重点介绍了胰腺、胃肠道和腹膜后/肾上腺神经鞘瘤，并与病理结果进行了相关性分析。我们的结论是，神经鞘瘤应包括在腹部肿块的广泛鉴别诊断中，当不需要根治性切除时，可以避免不必要的手术。
