Figure 2. (a) Contrast enhanced CT (CECT) scan at the level of bladder dome showing a thick walled, rim enhancing collection related to the anterosuperior aspect of the bladder. Note the relatively high density of the collection as compared with the urine in the bladder, suggestive of infected turbid contents. (b) CECT scan at the level of the umbilicus shows the heterogeneously enhancing collection with adjacent fat stranding extending up to the umbilicus.
