Inflammatory myofibroblastic tumor of the spleen
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
