case_images: Clockwise from top right: coronal and axial T2 weighted images, T1 fat suppressed post-contrast image and apparent diffusion coefficient image; this shows the soft tissue tumor arising from right inferior aspect of the bladder with a feature of high vascularity and restricted diffusion.

case_images: The MRI of the urinary bladder revealed the 33 mm lobulated lesion (Fig. 1).
case_images: 123I MIBG whole-body planar scintigraphy and fused axial image at the level of the bladder mass (left and top middle); 68Ga DOTATATE whole-body PET/CT three-dimensional maximum intensity projection image and fused axial image at the level of the bladder mass (right and bottom middle). These show the bladder tumor to be showing intense uptake of 123I MIBG but little uptake of 68Ga DOTATATE. Abbreviations: 123I MIBG, iodine-123-metaiodobenzylguanidine; 68Ga DOTATATE PET/CT, tetraazacyclododecane tetraacetic acid-DPhe1-Tyr3-octreotate positron emitting tomography.

case_images: The urinary bladder was otherwise thin-walled, with no other focal lesion. 123I MIBG SPECT-CT of the abdomen and pelvis showed an intensely avid bladder mass measuring up to 4.3 cm in size, suggestive of a bladder paraganglioma. 68Ga DOTATATE PET/CT did not reveal any avid lesions around the bladder or anywhere else in the body (Fig. 2).
