Abstract

<p>A 48-year-old woman with abdominal pain presented for a detailed examination because abdominal ultrasonography revealed a mass in the head of the pancreas. Contrast-enhanced CT scan showed a 15mm solid mass with delayed enhancement on the ventral side of the pancreatic head and T2-weighted MRI showed a high intensity mass. EUS showed a 15mm hypoechoic well-circumscribed mass in the pancreatic head. Based on these imaging findings, a pancreatic tumor was suspected, possibly a neuroendocrine tumor or solid pseudopapillary tumor, but further diagnosis was difficult. Therefore, EUS-FNB was performed and histopathology showed proliferated spindle cells arranged in fascicles with positive for protein S-100 on immunohistostaining, consistent with a pancreatic Schwannoma. With the history of abdominal pain, a decision was made to proceed with surgery and laparoscopic enucleation successfully performed. Final histopathological evaluation showed a pancreatic Schwannoma without malignancy. She was discharged on postoperative day 12 without complications and has no abdominal pain or recurrence 1 year postoperatively.</p>
