Because barium sulfate (BaSO(4)) is not harmful to the mucosa, it is widely used for gastrointestinal imaging. Barium appendicitis is a very rare complication of barium meals and barium enema. We report a case of acute appendicitis associated with retained appendiceal barium. A 47-year-old man presented with right lower abdominal pain after upper gastrointestinal imaging was performed using barium 1 month earlier. The abdominal plain roentgenogram showed an area of retained barium in the right lower quadrant. Multiplanar reconstruction of computed tomography scans showed barium retention in the appendix. Emergency appendectomy was performed. A cross section of the specimen revealed the barium mass. Barium-associated appendicitis is a very rare clinical entity but we should be cautious of this uncommon disease when we encounter barium deposits in the appendix after barium examination. This report is significant because barium was identified both macroscopically and microscopically.

A barolith consists of inspissated barium associated with feces and is seen, rarely, after barium studies for imaging the gastrointestinal system. The barium used in such studies can enter the appendiceal lumen and, rarely, cause appendicitis by obliterating or narrowing the lumen of the appendix. The appendix fills with barium and the entire appendix is visualized in 80-90% of barium swallow or enema studies, and this is accepted as a reliable sign of a non-diseased appendix Post-examination retention of barium in the appendix is very common (90~95%), and 10% of the patients retain barium in the appendix beyond 72 hours. If the barium is retained for more than two months, complicated appendicitis can result. We present a 46-year-old male who was diagnosed with acute appendicitis due to a barolith and required an appendectomy three months after a double-contrast barium enema study. After barium studies, patients should be informed regarding retention of barium in the appendix and the possibility that it can cause acute appendicitis. Thus, if abdominal pain develops, the patient can be referred quickly to a medical center for the appropriate treatment and the complications of acute appendicitis can be prevented with early intervention.

Barium sulfate is widely used for gastroenterology imaging. Retention of barium in the appendix, where it acts as an appendicolith, thereby leading to obstruction and inflammation. Barium-associated appendicitis is a very rare complication of upper gastrointestinal imaging (UGI), especially in children. We present a case involving an 8-year-old girl who was diagnosed with acute appendicitis due to a barolith and required a laparoscopic appendectomy 6 weeks after UGI. After UGI, patients should be informed regarding possible retention of barium in the appendix, which can cause acute appendicitis. Then, a laparoscopic appendectomy was performed successfully. We should be cautious of this potential risk to prevent complications with early intervention in children.
