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.
Conclusion:
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.
