Abstract
Teaching Point: A submucosal bladder wall lesion with high signal on T2-weighted MRI warrants blood and urine analysis to rule out a paraganglioma.

Teaching Point: A submucosal bladder wall lesion with high signal on T2-weighted magnetic resonance imaging (MRI) warrants blood and urine analysis to rule out a paraganglioma
Bladder paraganglioma is an exceedingly rare tumour arising from the chromaffin cells of the bladder, which explains their intramural location
Summary
Case History A 57-year-old male presented with right flank colic pain. Non-contrast computed tomography (CT) (Figure 1A) confirmed right-sided obstructive urolithiasis and incidentally revealed a sharply delineated oval mass (2.6 cm) in the left bladder wall containing a punctate calcification. Teaching Point: A submucosal bladder wall lesion with high signal on T2-weighted MRI warrants blood and urine analysis to rule out a paraganglioma. Non-contrast computed tomography (CT) (Figure 1A) confirmed right-sided obstructive urolithiasis and incidentally revealed a sharply delineated oval mass (2.6 cm) in the left bladder wall containing a punctate calcification. Complementary Doppler ultrasound (Figure 1B) showed well-vascularized lesion.
