Bladder wall thickening (differential)

Differential diagnosis for bladder wall thickening depends on whether the bladder is adequately distended. The bladder wall may be thickened if:

  • >3 mm when distended
  • >5 mm when nondistended

If the bladder is not distended, then it is difficult to exclude artifactual thickening from a collapsed bladder

If the bladder wall is adequately distended, then a differential may be developed based on whether the bladder is diffusely thickened or focally thickened:

Diffuse bladder wall thickening
Focal bladder wall thickening
