Fat Within the Wall of the Urinary Bladder: Computed Tomographic AppearanceThickman, David MDJournal of Computer Assisted Tomography: September-October 2009 - Volume 33 - Issue 5 - p 695-697 doi: 10.1097/RCT.0b013e31818d8de6 Abdominal Imaging Buy Abstract Author InformationAuthors Article MetricsMetrics 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.
