Endometriosis is defined as the presence of endometrial tissue outside the 
uterus. The bowel is not often affected. There are no specific clinical findings 
for intestinal endometriosis. It is typically asymptomatic, but sometimes can 
present with abdominal pain, diarrhoea, constipation or intestinal obstruction. 
Ileal perforation is a rare complication of intestinal endometriosis and only a 
few cases have been reported in the literature. Intestinal endometriosis can 
mimic many gastrointestinal diseases, such as irritable bowel syndrome, 
inflammatory bowel disease, infections and neoplasms. The diagnosis is made by 
laparoscopy or laparotomy. We present a case of a woman with intermittent 
abdominal pain and ileal perforation secondary to intestinal endometriosis.
