Imaging findings of ruptured abdominal and pelvic tumors

Abstract

A variety of abdominal and pelvic tumors can present with rupture leading to hemoperitoneum/hemoretroperitoneum or peritonitis. Imaging plays an important role in the diagnosis of hemorrhage or peritonitis as well as in the detection of ruptured tumors or organs. In this article, we illustrate the imaging findings of ruptured tumors arising in the abdominal and pelvic organs while excluding those of ruptured tumors arising in the stomach and intestines. It is important for the radiologists to understand the mechanisms involved in tumor rupture and recognize the imaging features of ruptured tumors according to the organs involved because this will permit the exact diagnosis of ruptured tumors, thereby facilitating prompt and effective treatment.
