Key Points

To present imaging findings of an inflammatory myofibroblastic tumor of the bladder using FDG PET/CT.
Described contrast-enhanced CT and FDG PET/CT findings
Assessed tumor characteristics such as hyperenhancement and SUVmax
Compared thickened mucosa metabolism to normal bladder wall
Tumor exhibited hyperenhancement on postcontrast CT
PET/CT showed high-grade activity with an SUVmax of 31
Thickened edematous mucosa displayed isoenhancement relative to normal bladder wall

Abstract

Inflammatory myofibroblastic tumor of the bladder is rare. We described contrast-enhanced CT and FDG PET/CT findings in an inflammatory myofibroblastic tumor of myxoid-vascular pattern involving the bladder muscular layer and adventitia with extensive edema of the adjacent mucosa. The tumor showed hyperenhancement on postcontrast CT and high-grade activity with SUVmax of 31 on PET/CT. The thickened edematous mucosa showed isoenhancement and isometabolism relative to the normal bladder wall. This case indicates inflammatory myofibroblastic tumor should be included in the differential diagnosis of FDG-avid lesions of the bladder.
