Concentric bladder wall thickening due to haemorrhage following suprapubic aspiration: ultrasound and CT features.

A 5-week-old baby with coagulopathy due to hepatic mitochondrial disorder developed a bladder haematoma secondary to suprapubic urine aspiration. Unlike previously reported cases, the haematoma manifested itself only as concentric thickening of the bladder wall without an intraluminal component. The ultrasound and CT features are described. Recognition of these findings is important when discussing the differential diagnosis of bladder wall thickening.
