title: Peritoneal sarcomatosis versus peritoneal carcinomatosis: imaging findings at MDCT.
abstract: OBJECTIVE
  Peritoneal sarcomatosis is an entity analogous to the better known peritoneal carcinomatosis. The purpose of this article is to discuss the imaging findings of peritoneal sarcomatosis versus peritoneal carcinomatosis.
  
  
  CONCLUSIONS
  Sarcomatosis is most commonly seen in gastrointestinal stromal tumor, liposarcoma, and leiomyosarcoma. A few distinguishing features of peritoneal sarcomatosis include heterogeneous bulky masses, hypervascularity with or without hemoperitoneum, and variable presence of ascites.
