CALCIFIED URACHAL REMNANT MIMICKING AS BLADDER WALL CALCIFICATION - CASE SERIES

Computer tomography of kidneys, ureters and bladder (CT KUB) is the main investigation in suspected renal tract calculi. Ultrasound of kidneys, ureters and bladder (KUB) region can come in hand during acute conditions especially in patients with ureteric calculus causing hydronephrosis and hydroureter. However, several pathologies other than renal tract calculi can cause apparent urinary bladder calcification. We describe series of cases who presented with renal colic. CT KUB performed on admission revealed a calcified urachal remnant mimicking a urinary bladder wall calcification, confirmed by reviewing the multi-planar reformatted images. We also discuss the differential diagnoses that should be considered when presented with urinary bladder calcification. Our study shows urachus calcification is much more common in patients than previously taught and more common in older patients of more than 50 years than younger patients. Males are commonly affected than females.
