Large Pedunculated Polyp Diagnosed as Inverted Colonic Diverticula

Large Pedunculated Polyp Diagnosed as Inverted Colonic Diverticula

We present a unique case of an inverted diverticulum mimicking a large adenomatous pedunculated polyp. Inverted colonic diverticula (ICD) are typically a few millimeters in size and may resemble a polyp. Our finding was unusual based on its size, location, and appearance. Incorrect management of ICD can lead to serious complications, therefore, endoscopists should be aware of this occurrence an...

Autoamputation of a large pedunculated colon polyp.

A 49-year-old man was referred for colonoscopy after a positive fecal occult blood test. Laboratory tests and physical examination were unremarkable but colonoscopy revealed a large pedunculated polyp in the sigmoid colon (●" Fig.1). Owing to inadequate bowel cleansing, polypectomy was not carried out. On repeat colonoscopy 120 days later, bowel cleansing was excellent. The examination was perf...

Inverted Meckel's Diverticulum Simulating Pedunculated Polyp as a Lead Point for Ileoileal Intussusception in a Child

Most of the intussusceptions in infants are idiopathic in nature. The incidence of intussusception decreases as the age advances. On the contrary, the frequency of lead point (secondary cause) increases with age. Meckel’s diverticulum is the commonest anomaly of small bowel. There is 5% incidence of complications in patients having Meckel’s diverticulum. Inverted Meckel’s diverticulum, as a lea...

Invasive cancer arising in a colonic inverted hyperplastic polyp.

py for the investigation of lower abdominal pain. Colonoscopy showed a whitish, flat, elevated polyp, 10mm in diameter, in the ascending colon (l" Fig. 1). Endoscopic mucosal resection (EMR) was carried out, and the resected specimen histologically revealed both invasive cancer and serrated adenomatous glands coexisting in an inverted hyperplastic polyp (IHP) (l" Fig. 2a–c). A follow-up colonos...
