Diagnosis
Bladder hematoma.
Findings
New large heterogeneous avascular bladder mass with layered appearance. Not present on renal ultrasound a few months prior and resolved on short term follow up.
Discussion
Bladder hematoma is most commonly post traumatic. Typical imaging features are an avascular/nonenhancing bladder mass that may fill the bladder and could have a layered morphology with an attenuation value in the range of 50-60 HU on CT. Primary differential is a neoplastic mass. Mobility of a hematoma is helpful to exclude a mass originating from the bladder wall. Resolution of a hematoma is typical and is aided by urokinase in urine.
