“…9,12 Less often, an appendiceal adenoma presents as an abdominal mass or as intussusception of the appendix. 9,12,[20][21][22][23][24][25][26][27][28] Approximately half of the cases are discovered in asymptomatic patients, particularly in women who have undergone an appendectomy during gynecologic surgery. Occasional patients with adenomas in the appendix have concomitant colonic adenocarcinoma.…”

“…The aetiology of appendicular intussusception can be broadly divided into anatomical and pathophysiological, as described by Rudek et al [4] and Langman et al [5]. Anatomical intussusception is characterised by the presence of an appendix originating directly from the bottom of the caecal pole.…”

Intussusception is a rare cause of adult intestinal obstruction. Clinical manifestations are not specific, which makes a preoperative diagnosis difficult to establish and often causes delay. We report a case of acute intestinal obstruction due to ileocolic intussusception. An emergency laparoscopy was performed revealing an obstructive mass at the ileocecal region resulting from an appendicular tumor. A right hemicolectomy was conducted. The pathologic examination of the resected sample concluded the mass comprised an appendicular mucinous cystoadenoma. We discuss the clinical features, preoperative diagnosis, and surgical strategies of adult intussusception, as well as the uncommon finding of an appendicular mucinous tumor as its causative lesion, with a review of the available literature.Key words: Adult intussusception -Appendiceal mucocele -Intestinal obstruction I ntussusception is the invagination of a proximal segment of bowel (intussusceptum) into the lumen of the adjacent distal segment (intussuscipiens). Pediatric patients account for 95% of all cases of intussusception, in whom it is usually idiopathic or the result of a viral process; whereas adult patients account for only 1% to 5%, and an organic lesion is found in up to 90% of the adult cases. 1,2Acute bowel obstruction due to intussusception is rare in adults and accounts for 0.003% to 0.02% of hospital admissions and for only 1% of all intestinal obstructions.1 Preoperative diagnosis is a real challenge for physicians because of its unspecific and extremely variable presentation and requires a high index of suspicion. Therefore, the initial diagnosis is usually missed or delayed and may only be established during surgery. [3][4][5] We present a very uncommon case of acute intestinal obstruction resulting from an ileocolic intussusception secondary to a mucinous tumor of the appendix and review the literature about this finding as a lead point. Case ReportA 57-year-old female presented to the emergency department with a 2-to 3-month history of intermittent and worsening abdominal pain, great- est in the right lower quadrant, which had increased gradually over the past 3 days. It was associated with dizziness and diarrhea but she denied any history of fever, nausea, vomiting, bloody stools, or weight loss. The patient's medical history included a groin hernia surgery and gastroesophageal reflux on oral treatment.Initial vital signs were within normal limits. Abdominal examination revealed diffuse tenderness on palpation, above all in the right lower quadrant, but without rebound or voluntary guarding. There was no palpable mass, and the auscultation found struggle bowel sounds. Blood tests were normal as was urine analysis.Abdominal X-ray exam was not demonstrative of intestinal obstruction. Computed tomography (CT) of the abdomen and pelvis showed a pathologic mass at the ileocolic region, of cystic appearance with parietal calcifications, with edematous pericolonic fat stranding suggesting of ileocolic intussusception causing an intestinal obstr...
