Pancreas is an Unusual Initial Metastatic Site of Intracranial Hemangiopericytoma

Abstract

Intracranial hemangiopericytoma (HPC) is rare and aggressive tumor with local recurrences as well as distant metastases. The majority of metastases are encountered in bone, lung, and liver. Pancreatic metastasis is extremely rare. Described in the present report is the case of a 41-year-old woman who had undergone surgical resection of intracranial HPC 16 years earlier. The tumor recurred 3 years after the operation and was successfully managed with surgery followed by adjuvant radiotherapy. Thirteen years later, an isolated pancreatic metastasis developed. Patient underwent Whipple procedure for pancreatic head lesion and received adjuvant radiotherapy. Patient died of extensive disease in lungs, bones, mediastinum, cranium and peritoneal carcinomatosis in abdomen 17 months after pancreatic surgery.
