Patient Data

Age: Young adult
Gender: Male

Delayed phase contrast enhanced CT

Delayed acquisition following contrast administration to evaluate the ureters and urinary bladder.

No ureteric or bladder injury. but the bladder is compressed laterally leading to it's odd shape, similar to a pear. The cause here is an extraperitoneal haematoma secondary to venous injury.
