Bladder wall fat on computed tomography with pathologic correlation

To determine the prevalence and significance of fat in the urinary bladder wall detectable by computed tomography (CT).Retrospective review of 200 consecutive patients with noncontrast CT. Cystectomy specimen CT/pathologic correlation.CT-detectable fat in 30 (15%) patients was significantly more predominant in men (P=.003) and in patients with past renal stones (P.001). Urinary tract infections were significantly less common in patients with bladder wall fat (P=.05). Pathologically, CT-detectable fat was submucosal.CT-detectable bladder wall fat is more common in men than women and in patients with a history of renal stones and urinary tract infections.
