UC San Diego

A 27-year woman presented with irritative lower urinary tract symptoms and alleged small right distal ureteric stone that had been diagnosed with KUB and non-contrast spiral CT. Patient was scheduled for ureteroscopic lithotripsy, revealing absence of the presumed stone, while cystoscopy showed unexpected 2 cm pedunculated grayish white lesion, situated on the right lateral wall of the bladder with sparse hairs covering it. An incomplete TURBT was done; the histological findings correlated with the gross picture seen on cystoscopy. Following CT urography, the patient went an open partial cystectomy and right oophorectomy; the histopathology was consistent with mature bladder teratoma.
