Synchronous intraoperative radiofrequency ablation for multiple liver metastasis and resection of giant solid pseudopapillary tumors of the pancreas

The solid pseudopapillary tumors of the pancreas (SPTP) are rare tumors, which are commonly found in adolescent women. Radical surgical resection of the primary tumor or metastases is the standard treatment for SPTP and could achieve long-term survival. We reported a case of a 20-year-old female with multiple liver metastases of SPTP, and performed surgical resection for primary tumor 14 cm in diameter and 2 major liver metastases (both 5 cm in diameter), radiofrequency ablation (RFA) for small lesions and one major liver metastase 6 cm in diameter successfully. No evidence of recurrence in situ or in the liver was found by computed tomography (CT) scan 3 months after the operation. RFA is a safe and effective treatment for unresectable multiple liver metastases of SPTP.
