Background

Hemoperitoneum consists of intra-abdominal bleeding and is usually associated with urgent conditions. The main bleeding sources can be divided into two main groups: traumatic with solid organ injury and nontraumatic. In the nontraumatic group, the main etiologies can be divided into tumor-associated hemorrhage, gynecologic conditions, vascular lesions and iatrogenic injuries.

Due to the rapid acquisition time and wide availability, Computed Tomography (CT) assumes a key role in identifying the cause and extent of the hemorrhage.
