case_images: MRI showed increased signal intensity in superficial and deep fascia layers on T2-weighted images (Figs. 1 and 3) with moderate fascia enhancement after contrast administration (Fig. 2), a muscle biopsy of the arm was performed showing an accumulation of eosinophil in the muscle aponeuroses (Fig 4). our patient was put on corticosteroid boluses as well as immunosupressants such as metotrexate, after 1 month of treatment there was a clear improvement in clinical signs as well as biology results showing a decrease in eosiniphilia, CRP and ESR.
case_images: Coronal sections of the arm and forearm showing diffuse hypersignal of muscle fascia.

case_images: Cutaneous-fascial-muscular biopsy of a patient with FE: hematoxylin-eosin staining shows dense, diffuse, perivascular inflammatory infiltrates in the fascia, composed mainly of lymphocytes, but also of eosinophils.
