Appendiceal intussusception is an rare diagnosis that may be found on imaging or at the time of surgery, as seen in this case of a 33-year-old female presenting with gastrointestinal symptoms. Images are presented with differential diagnosis as well as treatment options. Case reportA 33-year-old white female presented with a several months' history of left lower-quadrant pain most notable after menstrual cycles. This was associated with episodes of intermittent loose stools alternating with constipation. Past medical history was significant for hypertension, anxiety and asthma. Previous surgical history includes a tubal ligation approximately 5 years earlier. On physical examination, her general condition was good and her abdomen was soft, although some tenderness was exhibited in the right lower quadrant. Laboratory tests and a urinalysis were grossly normal with a white cell count of of 9,990/mm 3 .The patient underwent a colonoscopy as part of the workup for her abdominal pain, at which time a lesion was discovered in the lumen of the appendix (Fig 1). The lesion was suspicious for a polyp or mucocele, which was benign on superficial cold biopsy. A follow-up abdominal computed tomography (CT) scan showed dilated, thickened appendix impinging on the cecum (Fig 2). After discussion with the patient regarding the possibility of mucocele, among other diagnoses, she agreed to proceed with a laparoscopic resection. A shortened, thickened appendix and cecum were dissected free from surrounding structures and lateral attachments to the abdominal wall were freed. A laparoscopic partial cecectomy with appendectomy was performed. The specimen consisted of an appendix measuring approximately 5cm in length by 1.7cm in diameter. Final pathology was read as benign appendix with intussusception in the setting of intramural endometriosis. This was negative for dysplasia and malignancy. The patient did well postoperatively and was discharged on hospital day two, tolerating a regular diet. DiscussionAppendiceal intussusception is an uncommon diagnosis, with an estimated incidence reported by Collins as 0.01%. 1 Clinical presentation of appendiceal intussusception can vary from crampy lower abdominal pain to acute appendicitis. 2 In this case, the patient had symptoms suggestive of a

“…Fink et al reviewed the literature in 1964 and found that less than 118 cases had been previously reported. Finally, Chaar et al made a comprehensive review in 2009 and presented 191 cases of appendiceal intussusception described in the English literature since then (Chaar et al, 2009). From all the above it is clear that appendiceal intussusception is an extremely rare lesion of the appendix.…”

There are many kinds of unusual presentations or associations and clinical mimics of acute appendicitis, and definitive diagnosis requires knowledge of the imaging findings in some cases. The unusual presentations and associations of acute appendicitis included in this study are perforated appendicitis, acute appendicitis occurring in hernias, acute appendicitis with cystic endosalpingiosis, intussusception of appendix, and acute appendicitis with pregnancy. We also present uncommon gastrointestinal, urinary and gynecologic clinical mimics of acute appendicitis including anomalous congenital band, duplication cysts, giant Meckel' s diverticulitis, inflammatory fibroid polyp, renal artery thrombosis, spontaneous urinary extravasation and OHVIRA syndrome. Familiarity with these entities may improve diagnostic accuracy and enable the quickest and most appropriate clinical management.
