Polypoid Cystitis in an Adult Without History of Catheterization

Abstract

Polypoid cystitis is a benign exophytic mucosal lesion of the bladder. Differentiating it from papillary transitional cell carcinoma is difficult due to their similar characteristics. Although indwelling catheter is the main well-known cause of polypoid cystitis, some case reports unrelated to catheterization have been described. However, the radiological findings of polypoid cystitis have rarely been reported. We hereby describe polypoid cystitis in a 20-year-old man without a history of catheterization along with the computed tomographic findings.

A Case of Polypoidal Cystitis Without History of Catheterization

“…The imaging features of cystitis are nonspecific and it is difficult to distinguish one form of cystitis from another, radiologically. The bladder wall thickening is similar to the changes that are seen in bladder carcinoma [4], [5]. Histopathological examination is the definitive diagnosis of polypoidal cystitis.…”

“…It is a benign lesion mimicking papillary urothelial neoplasm due to the papillary fronds seen grossly [1]. It occurs more commonly due to repeated catheterization of the bladder [2], only few cases have been reported in literature without the history of catheterization [3], [4]. We report one such case of polypoidal cystitis in a 26 year old female.…”

Polypoid cystitis in a male entire springer spaniel puppy

“…Polyps have been associated with chronic irritation of the bladder mucosa by urinary tract infection or uroliths in both people and animals 1 6 11 12. In human beings, polypoid cystitis has also been reported with chronic or recurrent urethral catheterisation, abdominal trauma, bladder vascular malformation or even without identified cause of recurrent mucosa irritation 2 11 13–15. A case of polypoid cystitis suspected to be secondary to Candida albicans infection has been recently reported in a newborn human being 3…”

Early-Onset Asymptomatic Polypoid Cystitis in Two Adolescent Male Beagle Dogs

“…1,2 However, in rare cases, patients have been diagnosed with polypoid cystitis without any history of previous catheterization or urinary problems. 7 In this study, urinary catheterization was used to collect urine on two separate occasions. As an increased number of red blood cells was detected microscopically for both dogs at the second urinalysis, it could be hypothesized that the initial catheterization resulted in mechanical trauma to the bladder wall, which subsequently lead to the development of induced polypoid cystitis.…”
