術前診断が可能であった膀胱パラガングリオーマの 1 例.

A 41-year-old woman was admitted to our hospital with a mass in her bladder, which was observed on ultrasonography after medical examination. Urinalysis and urine cytopathology did not show any abnormalities; however, cystoscopy revealed a 1-cm submucosal tumor on the right wall of the bladder. Although endocrinological examination showed no significant abnormalities, bladder paraganglioma was suspected, because 123I-MIBG scintigraphy showed staining on the bladder tumor. Partial cystectomy was performed with sufficient preoperative management. Histopathological diagnosis revealed bladder paraganglioma. There were no complications during the perioperative period, and she was discharged 9 days after surgery. No recurrence has been observed over a period of 1 year since the surgery.
