title: Fat within the wall of the urinary bladder: computed tomographic appearance.
abstract: OBJECTIVE
  The objective of this paper was to describe the computed tomographic appearance, characteristics, and significance of fat in the wall of the urinary bladder.
  
  
  METHODS
  Twenty-three cases of intramural fat were reviewed. Use of intravenous contrast, sex, and degree of bladder distention were noted. Location of intravesical fat was tabulated.
  
  
  RESULTS
  Intramural fat is typically seen as a thin low-density band along the anterior and superior portions of a partially filled urinary bladder. Most of the cases are in men (90%) and are seen on unenhanced studies (>80%). The prevalence of intramural fat was just less than 2%.
  
  
  CONCLUSIONS
  Fat within the wall of the urinary bladder can be a normal histological finding that is detected at computed tomography typically in patients with nondistended urinary bladders on unenhanced studies.
