Abstract.

The diverticula are mucosal outpouching of the bladder not having the muscle layer and contractile activity; so they are a place of urine stasis resulting into complications like stone formation and urinary tract infection. The majorities of bladder diverticula are acquired, secondary to bladder outlet obstruction. Carcinoma arising within urinary bladder diverticula has a poorer prognosis than do neoplasms that originate within the main bladder lumen because the thinner diverticular wall would allow earlier spread. MR is the method of choice after cystoscopy for staging infiltration of the bladder wall and especially in the cases when a intradiverticular tumor can be missed cystoscopically when tumor invasion has spread into the lumen of the bladder and can be misinterpreted as a solid mass.

Key words: BLADDER DIVERTICULA. BLADDER TUMORS. MRI
