This retrospective analysis evaluated the clinical and radiologic results of transcatheter arterial embolization (TAE) in the treatment of significant hemobilia. The imaging findings, embolization technique, complications, and efficacy are described. ⋯ TAE is a safe and effective interventional radiologic procedure in the nonoperative management of patients who have significant hemobilia.

We present a case of perforation of the sigmoid colon due to blunt abdominal trauma. Computed tomography showed nominal free air in the inguinal fossa. The distribution of free air may be a clue to the site of an injured intestine. Early detection of intestinal injury is difficult, but repeated computed tomography after several hours may reveal increased free air.

We evaluated the value of computed tomographic (CT) gastric virtual endoscopy (VE) by comparing it with real gastric fiberscopy (GF). ⋯ Because VE is a good noninvasive screening method, except for minimal radiation exposure, it is expected to become a new technique for stomach examinations.

This case report describes a sigmoid diverticulitis with torpid development, long-term symptoms of bladder irritability, and an emphysematous epididymitis caused by a direct seminal vesicle fistula. The diagnosis was suggested by scrotal ultrasound visualizing gas in the scrotum; the complex pelvic fistulous tract was specifically delineated by multislice computed tomography. This may be the first reported case of seminal vesicle fistula directly related to colonic diverticulitis and causing emphysematous epididymitis.

Multiseptate gallbladder is a rare congenital malformation. We present a case that emphasizes the importance of ultrasonography and magnetic resonance imaging. Ultrasound examination of the abdomen showed multiple linear internal echoes consistent with multiple septa crossing the entire gallbladder lumen, creating a honeycomb appearance. Magnetic resonance cholangiopancreatography showed a grapelike cluster of the whole gallbladder.
