Colonoscopic Diagnosis of Appendiceal Intussusception : A Case Report

Abstract

Intussusception of the appendix is an uncommon condition and the diagnosis is rarely made preoperatively. Intussusception of the appendix may mimic a neoplastic lesion. Colonoscopy is a valuable tool for diagnosis of the appendiceal intussusception. A 17-yr-old female admitted with repeated abdominal pain, nausea, vomiting and febrile sensation. We diagnosed as appendiceal intussusception by colonoscopy, which showed a polypoid tumor (about 1.5 cm) in the cecum. This sessile polypoid mass looks like foreskin or glans. We present colonoscopic finding of appendiceal intussusception and review the literature.

Appendiculo-caecal intussusception

“…The condition is four to five times common among the males than in the females. 4 Our patient was a 45-year-old female.…”

“…5,6 Appendiceal intussusception has often been misdiagnosed as a caecal polyp in endoscopy when there is a neoplasm of appendix. 4 Pathologically intussusception of the appendix has the following characteristics: (a) Lesions inside the lumen like faecoliths, foreign bodies. (b) Lesions of the wall like hypertrophic lymphoid follicles, adenovirus infections, mucosal polyps, mucoceles, adenocarcinoma, carcinoid, endometriosis, tuberculosis, and mucinous cystadenoma.…”

Intussusception of the Appendix and Ileum Endometriosis: A Case Report

“…Appendiceal intussusception can be observed during colonoscopy [1,6,9,13], where it may appear as a sessile or elongated polypoid mass [14]. It is important not to mistake it with a cecal polyp, which can lead to iatrogenic complications after endoscopic removal of such a ‘polyp' [9,10,15]. Even a simple biopsy of it can provoke bacterial infection [10].…”

Invaginación intestinal recurrente secundaria a apéndice cecal invaginado: Caso clínico

“…Se ha descrito que detecta hasta un 71% de los factores anatómicos responsables de una invaginación 5 . otra alter-nativa diagnóstica es la colonoscopia, la cual nos permite ver una lesión polipoidea ubicada en el ciego donde debiese verse el apéndice cecal [10][11][12] .…”
