There are a relatively well-circumscribed intermuscular soft tissue mass in the right groin region which exhibits an iso-signal to the muscles on T1WI, high signal on T2WI with central area of low signal (maybe due to a dense central area of collagenous stroma) with restricted diffusion on DWI/ADC. The postcontrast sequences show a heterogeneous enhancement. The femoral nerve was not visualized.
Case Discussion
MRI features are most consistent of a peripheral nerve sheath tumor (neurofibroma of the femoral nerve histologically proven). Neurofibromas are considered WHO grade I tumors under the current (2016) WHO classification of CNS tumors
