“…[10][11][12][13][14][15][16][17][18][19][20] Ponsky first described the detection of appendiceal mucocele by colonoscopy in 1976 as a yellowish, submucosal, lipomalike mass. 21 In the largest series to date, Zanati et al described seven patients with mucinous cystadenoma of the appendix detected on colonoscopy over a 14-year period at a single institution.…”

“…However, the reports of endoscopic sonography for the detection of appendiceal lesions are limited. 28,29 In our case, a complexity of structure can be inferred by concentric hyper-and hypoechoic rings, the so-called ''multiconcentric ring sign.'' Once intussusception of the appendix is diagnosed, it can be readily treated by surgical reduction and appendectomy.…”

Intussusception of the appendix vermiformis is an uncommon cause of abdominal pain. Several imaging modalities are of limited value in diagnosing this rare condition, including barium enema, transabdominal sonography, and CT. We report a case of intussusception of the appendix vermiformis with the clinical presentation of intermittent abdominal pain in the right lower quadrant. Colonoscopy revealed an erythematous polypoid lesion at the cecal base. Endoscopic sonography demonstrated a multiconcentric structure and enabled the tentative diagnosis of intussusception of the appendix vermiformis. Laparoscopic surgery with a reduction of the appendix and appendectomy was performed and confirmed the diagnosis.

“…Several EUS case reports of this lesion have been reported. These describe an extrinsic cystic mass with papillary, tumor-like elevations [14, 15]. The wall layer of origin was difficult to ascertain for the lesions in the current series.…”

Background. The use of through-the-scope (TTS) miniprobe catheter endoscopic ultrasound is a valuable technique for evaluating subepithelial lesions in the proximal colon. Few reports include the evaluation of the appendix by EUS. Objective. To describe endoscopic and endosonographic characteristics of subepithelial lesions of the appendix. Methods. Retrospective case series in a single academic medical center. Adult patients referred for evaluation of subepithelial lesions of the appendix identified by colonoscopy between April 1, 2003 to February 29, 2008. Data were abstracted from an electronic endoscopic database for all patients undergoing miniprobe endoscopic ultrasound examination of the appendix. Medical records were reviewed for patient followup and outcomes. Results. Nine cases were identified. Seven (78%) patients were female. Seven (78%) utilized the 12 MHz miniprobe device and two (22%) used the 20 MHz device. Three mucoceles were described and confirmed by surgical resection. Cases also included one inverted appendix, one gastrointestinal stromal tumor, and one lipoma. In three cases, no abnormality was found. Conclusions. EUS evaluation of the appendix is feasible with standard miniprobe devices and may assist in the selection of patients who may benefit from surgical management.
