Since the first case was known by Kelly and MacCallum in 1898, gas-forming bacterial infection of the urinary tract has been reported infrequently. This disease occurs more frequently in diabetics or women, and is mainly caused by aerobic Gram negative bacteria, most commonly E. coli. Although the pathogenesis of gas formation in this disease is still poorly understood, glucose fermentation by the causative bacteria has been considered as the main mechanism. In the literature, the majority of cases reported were emphysematous pyelonephritis and/or emphysematous cystitis, together or separately. But simultaneous development of emphysematous infection of kidney, ureter and bladder has been reported very rarely and no case has been reported yet in Korea. We report a case of emphysematous pyelonephritis, ureteritis, and cystitis which occurred simultaneously in 35-year-old female patient with diabetic renal failure and neurogenic bladder.

Inflammatory fibroid polyp is a polypoid lesion of the gastrointestinal tract, composed of fibrous tissue, blood vessels, and inflammatory infiltration often dominated by eosinophilic leukocytes. It is infrequent, localized, and non-neoplastic condition. It is most often formed in the gastric antrum and ileum, and rarely in the esophagus, small bowel or colon. The polyp in the stomach is mainly located in the submucosa of the antrum, and may cause intermittent epigastric pain, vomiting, antral obstructive symptoms or rarely bleeding. When present in small bowel, it is usually localized in the ileum and presents with obstructive symptoms but clincal manifestations are different according to the location. Intussusception resulting from the mass is not common. We report a case of inflammatory fibroid polyp of the cecum causing intussusception. A 42-year-old male patient was referred to the hospital for the evaluation of right lower quadrant abdominal pain and palpable mass. A contrast-enhanced CT scan of the whole abdomen and colonoscopic examination revealed intussusception with a cecal mass. Inflammatory fibroid polyp causing intussusception was histologically confirmed by surgical wedge resection.
