Endometriosis of the abdominal wall: regarding a rare case

Abdominal wall endometriosis is defined as the ectopic implantation of endometrial tissue on the abdominal wall. It is a rare and often overlooked condition with a poorly understood physiopathology, that generally occurs on scars from abdominal, gynecological or obstetrical surgeries. The typical clinical presentation is that of a parietal mass associated with pain accentuated by the menstrual cycle. Imaging plays a key role in the diagnosis, ultrasound in particular, since it is the first examination to be carried out in the event of suspicion of parietal endometriosis. Abdominal and pelvic magnetic resonance imaging play a key role in the diagnosis, as well as surgical planning. The definitive diagnosis is confirmed by histology.We present the case of a patient who consulted due to cyclical pain in the left iliac fossa and in whom ultrasound and magnetic resonance imaging revealed a lesion of the anterior abdominal wall lateralized to the left suggestive of parietal endometriosis and whose diagnosis was confirmed by histology.
