Intradiverticular Bladder Carcinoma-A Rare Case Report

Abstract

The most common intradiverticular malignancy is urothelial cancer. Bladder diverticula can be caused either by congenital or acquired defects which results in out pouching of the bladder wall. Intradiverticular urothelial lining is more predisposed to bladder carcinoma as compared to the anatomically normal urinary bladder wall. Acquired diverticula are by far more common and are secondary to lower urinary tract obstruction, such as benign prostatic hyperplasia, vesical neck contracture, urethral stricture or neurogenic bladder. Due to its rarity, intradiverticular carcinoma is not so frequently encountered in general practice. Most malignant tumours in vesical diverticula are of transitional type (about 78% of total cases), followed by squamous cell carcinoma (17%), a combination of transitional and squamous cell types (2%) and rest are adenocarcinoma (2%). Diagnosis of vesical diverticula follows ultrasound, radiologic examination (intravenous pyelography and/ or cystography) and cystoscopy. In cases of diverticula with narrowed openings, a tumour in a diverticulum may be overlooked. In these cases, CT, transvesical and transrectal ultrasound is of great importance for detection of an intradiverticular tumour.
