Appendiceal mucocele is a rare cause of pain in the right lower abdominal quadrant. This case report describes a case of coexistence of endometriosis and appendiceal mucocele, which were diagnosed pre-operatively by computed tomography, magnetic resonance imaging and ultrasonography. Laparoscopic excision of the appendiceal mucocele and endometriosis resulted in the disappearance of the symptoms.
