Barium Granuloma of the Rectum: Case Report

Abstract

When barium extravasates into tissue during radiologic procedures such as barium enema, it is uptaken by macrophages and forms a granuloma. The result of this is a tumorous mass, fibrosis, and stricture (1), and a cancerous condition is sometimes wrongly suspected. In almost all cases of barium granuloma there is a history of barium enema, a fact which is helpful in making the correct diagnosis. We report a case of barium granuloma in which there was no history of barium enema or apparent rectal trauma.

Barium granuloma in peritoneal cavity and right scrotal sac mimicking a germ cell tumor

“…Sometimes the barium granuloma can mimic a tumorous mass and give incorrect presumptive diagnosis. Kim et al reported a barium granuloma of the rectum whose preoperative diagnosis was calcified submucosal tumor such as gastrointestinal stromal tumor [1]. Our case had the previous colonic biopsy at splenic flexure and then the patient developed a post-operative intra-abdominal collection that were the predisposing factors for colonic Discussion perforation during barium enema procedure.…”

“…It was first described in 1954 as a pedunculated rectal mass [1,2]. Most of the previous reported cases had a history of barium enema.…”

“…Most of the previous reported cases had a history of barium enema. A recent reported case by Kim et al, however, diagnosed a barium granuloma of the rectum in a patient with no history of barium enema but the patient underwent upper gastrointestinal series and colonoscopy was performed nine months later [1]. Colonic perforation after barium enema can occur at any level from dentate line up to cecum and it can be complete entire thickness of colonic wall or incomplete with intact colonic serosa [3,4].…”

“…Barium within peritoneal cavity can create severe inflammatory reaction encountering fibroblasts, multinucleated cells, macrophages and lymphocytes which are the characteristics of a granulomatous reaction surrounding the barium sulfate crystal [1,8]. Later on, it can produce a fibrotic change resulting in colonic stricture or intraperitoneal adhesion/fibrosis.…”

Synthesis of GaAs/SiO2 Nanocomposite Films by Using an Alternating Sputtering Method

“…Semiconductor-dielectric composite films, which consist of semiconductor nanoparticles embedded in transparent dielectric media, have attracted a great deal of attention because of their great application potential in future optical and photonic devices such as low-threshold quantum dots lasers, optical amplifiers, and light-emitting diodes [1][2][3]. Such composite films have shown very interesting dependences of their optical and electrical characteristics on the sizes of the semiconductor-nanoparticle constituents due to quantum size effects and on the distribution of the semiconductor nanoparticles [4,5]. Therefore, development of fabrication methods that can control the sizes and the distributions of the semiconductor-nanoparticle constituents has been the focus of research.…”
