Abstract

Hemangiopericytoma (HPC) is a rare mesenchymal tumor derived from capillary and postcapillary pericytes that often has an indolent course and occasionally presents with abdominal metastasis. Twenty-three years after the initial resection of an intracranial HPC located in the right frontoparietal region and left lateral ventricle, a 63-year-old man experienced dull abdominal pain and early satiety and had a palpable epigastric mass. Computed tomography indicated a suspected metastasis of HPC to the left upper abdomen. On laparoscopic exploration, the tumor was found in the falciform ligament and was excised laparoscopically per request of the patient. He had a fast recovery and experienced good relief of his pain and satiety. The patient had 2 additional metastases at his 12-month follow-up, both in the right retroperitoneum, and he again underwent laparoscopic resection. At his next annual follow-up, new metastases were identified in his liver, small-bowel mesentery, and peritoneal surface, prompting a trial of systemic chemotherapy. Because of progress of a left lower abdominal preperitoneal metastasis on follow-up at 3 years, the patient underwent a further successful laparoscopic exploration. Postoperatively, systemic chemot...Continue Reading
