Appendiceal endometriosis


The clinical manifestations of the patient were not definite for acute appendicitis. The CT picture directs toward elective laparoscopic appendectomy. The histopathology surprisingly revealed appendical endometriosis.

The gastrointestinal tract is involved in endometriosis in 12-37% of patients.

Appendiceal endometriosis should be considered in the differential diagnosis of women of reproductive age complaining of right iliac fossa pain especially if the clinical, laboratory, and imaging features are not typical for acute appendicitis.

The presence of other imaging features of endometriosis (adenomyosis, adnexal lesions) as seen in this case, can help in this suspicion on imaging.
