摘　　要：BACKGROUND Paraganglioma of the urinary bladder(PUB)is a nonepithelial tumor of the bladder that is also known as bladder pheochromocytoma.The incidence of nonfunctional paraganglioma of the urinary bladder is rare in clinical practice.CASE SUMMARY A case of nonfunctional paraganglioma of the urinary bladder diagnosed and treated in our hospital is reported herein.A 2.5 cm×2.1 cm moderate-echo mass protruding into the right anterior wall of the bladder was incidentally found during transvaginal color Doppler ultrasound examination.Based on a contrastenhanced computed tomography scan of the bladder,the right anterior wall of the bladder was considered to present a hemangioma.The patient underwent laparoscopic partial resection of the bladder wall in our hospital,and pathological results showed paraganglioma of the bladder.At present,we have followed up with the patient for half a year,and there has been no recurrence of the tumor.CONCLUSION The imaging patterns of PUB and bladder hemangioma are similar.In clinical practice,the possibility of PUB should be considered for a single wide-based isoechoic mass in the bladder,especially functional PUB may cause some adverse effects during surgery.
