CT images show large diverticulum arising from left infero-lateral wall of urinary bladder (neck- 14 mm) measuring 11 x 5.8 x 9.7 cm (AP x TR x CC). The diverticulum is located at the level of left vesico-ureteric junction with left distal ureter opening into the diverticulum. These features are consistent with large congenital Hutch diverticulum of urinary bladder.
The diverticulum shows irregular wall thickening and enhancement- representing diverticulitis. Small calculus is noted in dependent portion of diverticulum.
Moderate left hydroureteronephrosis is noted with dilated extrarenal pelvis. No ureteric calculus is seen. There is medial deviation, stretching and narrowing of left distal ureter by the large diverticulum resulting in hydroureteronephrosis.
Left kidney is small in size with moderate parenchymal thinning.
