Inflammatory myofibroblastic tumors of the spleen are rare spindle cells tumors of indeterminate clinical behavior. Please refer to the article on inflammatory myofibroblastic tumors for a broad discussion on the subject.
They usually present as a well defined hypoechogenic splenic mass 1.
Well defined hypodense splenic mass that, on postcontrast images, shows delayed heterogeneous enhancement. A central hypodense scar is recognized as a feature. Calcifications may be present 1.
- T1: low- to iso-intensity
- T2: bright signal within the central scar
- T1 C+ (Gd): delayed postcontrast enhancement
