1)The rectovesical and rectouterine excavations (cul-de-sac) are the inferior drainage spot of the peritoneal cavity and one of the first affected zones involved in intraperitoneal diseases. 2) Changes in this region must direct radiologist to investigate a number of specific primary sites and, in emergency department, alert for acute life threatening conditions. 3) Although varied number of female pathologies are described in cul-de-sac, men also present typical lesions of this region.

1) Review the anatomy of the pelvis and peritoneal cavity with a focus in it´s recesses and variations between genders. 2) Discuss fluid in cul-de-sac and it´s possible source and implications. 3) Demonstrate typical conditions that affect this site seen on MRI, divided as follows:  * Neoplastic: peritoneal carcinomatosis, sarcomatosis, pseudomyxoma peritonei, contiguous tumorextension. * Inflammatory / Infectious: Inflammatory pseudotumor, pelvic inflammatory disease, abscesses by diverticulitis/appendicitis, peritoneal tuberculosis. * Miscellaneous: endometriosis, splenosis, iatrogenic, peritoneal inclusion cyst. * Male conditions: mullerian cyst, extracapsular extension of prostatic carcinoma.
