Spontaneous prevesical (Retzius-space) abscess with extraperitoneal presacral dissemination. A case report

The workup of a pelvic mass should not be limited to intraperitoneally located organs. Pathologic conditions of the abdominal wall, although rare, can mimic an intraabdominal process. One example of such conditions is the spontaneous (atraumatic) appearance of an abscess in the retrofascial-prevesical space of Retzius.
