A Case of Incidental Detection of Asymptomatic Bladder Cancer by Transvaginal Ultrasound.

We report a case of an incidental diagnosis of early asymptomatic bladder cancer using transvaginal ultrasonography. The patient was a 68-year-old female without urinary symptoms. Transvaginal ultrasonography revealed a 2-cm papillary mass in the bladder mucosa. Urine cytology revealed the presence of atypical cells indicative of malignancy. Cystoscopy revealed a stalked papillary tumor at the apex of the posterior wall of the bladder. Transurethral resection of the bladder tumor was performed, and a 2-cm papillary tumor was resected. A pathological diagnosis of non-muscle-invasive bladder cancer was made.
