BACKGROUND: To investigate the imaging findings of bladder paraganglioma (BPG) and improve the imaging recognition and diagnostic accuracy of the disease.
METHODS: The clinical and imaging data of 10 cases of BPG confirmed by operation and pathology were retrospectively analyzed from the aspects of tumor location, size and morphology, presence or absence of necrosis, cystic change and calcification, and enhancement methods.
RESULTS: Of the 10 cases, 7 cases underwent basal and contrast enhanced computed tomography (CT) scan examination, 1 case underwent basal and contrast enhanced MRI scan examination, and 9 cases underwent ultrasonography examination; 5 cases were located in the right wall of bladder, 3 cases were located in the left wall, and 2 cases were located in the bottom wall; 2 cases showed necrosis, 1 case had cystic degeneration, and 2 cases had arcuate and semicircular calcification; both contrast enhanced CT and MRI examinations showed significant post-contrast enhancement; in 9 cases of ultrasonography examination, 5 cases had hypoechoic mass, 3 cases had moderate echoic mass, and 1 case had hyperechoic mass.
CONCLUSIONS: The imaging findings of BPG have certain characteristics, and combining with clinical history is helpful for accurate preoperative diagnosis.
