Malignant Retroperitoneal Hemangiopericytoma: Report of a 73 Years Old Woman and Review of Literature

Abstract

Introduction: Hemangiopericytomas (HPCs) are rare neoplasms which account for approximately 1% of primary vascular tumors. Case Presentation: We report a 73 years old woman with vague abdominal pain who did not have further significant symptoms and was diagnosed to have retroperitoneal hemangiopericytoma. Discussion: The tumor was initially diagnosed by ultrasound evaluation. MRI showed a lobulated mass at lower lateral quadrant of the abdomen, adjacent to left psoas muscle with small cystic components. Successful surgical resection of the tumor indicated a solitary large encapsulated 10 × 7 × 4 centimeter retroperitoneal multiloculated mass. Subsequent pathologic studies confirmed the tumor to be malignant hemangiopericytoma. The patient is currently well and is evaluated by periodic CT scans.

Measurement of colonic transit time based on radio opaque markers in patients with chronic idiopathic constipation; a cross-sectional study

“…Idiopathic constipation is divided into three subtypes: 1) Constipation with normal colonic transit, which is often associates with psychosocial abnormalities ( 17 , 18 ); 2) Colonic inertia (slow transit constipation). Most of the patients with severe constipation and abnormal colonic transit have colonic inertia, that in this case, transit of particles via colon is slow; 3) Outlet obstruction, in which food particles pass normally through the colon but slowdown in rectum ( 19 , 20 ).…”
