title: A Rare Case of Vesicourachal Diverticulum with Calculus in a 24-Year-Old Man.
abstract: BACKGROUND
  During embryonal period, complete obliteration of the urachus at the umbilicus and incomplete closure at the bladder level are the cause of vesicourachal diverticulum. This abnormality is a rare finding that is usually discovered incidentally during radiological evaluation. Occasionally, stones have been detected within the diverticulum.
  
  
  METHODS
  We present a case of a vesicourachal diverticulum with calculus diagnosed by multidetector computed tomography and confirmed surgically and histopathologically in a 24-year-old man.
  
  
  CONCLUSIONS
  During the radiological differential diagnosis of abnormalities of abdominal wall and urinary system, consideration of urachal abnormalities is important especially in symptomatic patients.
