摘要

Pancreatic schwannomas are rare pancreatic tumors. We describe an extremely rare case of a patient having a large pancreatic schwannoma and multiple benign peripheral nerve sheath tumors (BPNSTs). A 37-year-old woman presented to our hospital complaining of right chest pain. Thoracic spine magnetic resonance imaging revealed an intradural mass at T4-T5. Additionally, we incidentally identified a right paratracheal mass and a large pancreatic cyst. The final pathology report confirmed a thoracic spine meningioma, a mediastinal schwannoma, and a pancreatic schwannoma. Three and 10 years after presentation, the patient was diagnosed as having benign nerve sheath tumors in the lumbar spine and left buttock region. Pancreatic schwannomas are rare but should be included in differential diagnoses of cystic pancreas tumors. This case report details the first recorded case of a pancreatic schwannoma with multifocal BPNSTs involving the mediastinum, the spinal canal, the pelvic cavity, and the lower extremities.
