Intussusception Secondary to a Cecal Submucosal Abscess: A Case Report

Abstract

A 45-year-old man visited our hospital for unrelenting abdominal pain since the day before presentation. Physical examination showed right upper abdominal tenderness. Blood tests revealed evidence of an inflammatory response; however, no other abnormalities were detected. Computed tomography revealed intussusception (telescoping of the small intestine into the ascending colon). A cystic lesion was detected near the root of the appendix in the advanced region. We performed colonoscopy, which revealed a submucosal tumor in the vicinity of the hepatic curve in the advanced region, and we performed ileocolic resection. Histopathological examination of the resected specimen showed an edematous lesion with inflammatory cell infiltration, and we also observed a submucosal abscess. Previous studies have reported that approximately 50% of the lesions were malignant, and 90% of patients underwent operation in cases of cecal intussusception. We report a rare case of intussusception secondary to a cecal submucosal abscess.
