Background And Importance: Malignant peripheral nerve sheath tumors (MPNST) are relatively rare tumors of peripheral nerves that are notable for their locally aggressive nature, ability to metastasize, poor prognosis, and association with Neurofibromatosis type I. We present the case of a patient with a trigeminal nerve MPNST who developed an unusual metastasis to the corpus callosum, in the absence of any other central nervous system or systemic metastatic disease. We review the pathology and presentation of MPNST.

- The ampulla of Vater is a crucial anatomical site where the common bile duct and main pancreatic duct meet, posing diagnostic challenges due to its complex structure and variety of possible lesions.
- Lesions can be neoplastic, inflammatory, or congenital, with types including adenocarcinomas, adenomas, and other cancers affecting the pancreas or duodenum, which can be difficult to differentiate through imaging.
- Common imaging techniques include ultrasonography, CT, and MR imaging; however, endoscopic methods may be required for a more accurate assessment, making radiologist expertise vital for diagnosis based on imaging features, patient history, and lab results.
