Fat within the wall of the urinary bladder: computed tomographic appearance. [Journal Article]
J Comput Assist Tomogr 2009 Sep-Oct; 33(5):695-7.
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.
