Abstract We present the case of a 66-year-old woman with generalized oedema and pain in the four limbs. Physical examination revealed a diffuse, painful, partly pitting, oedema of forearms, hands, lower legs and feet. There were no signs of synovitis. Laboratory investigation was non relevant, exept for mild eosinophilia, which normalized subsequently. Cardiac, nephrological and venous disturbances were excluded. More uncommon disorders, such as eosinophilic fasciitis, early stage of scleroderma and polymyositis were considered. MRI scanning of the right forearm revealed an increased signal intensity in the superficial muscle fibers and thickening of the fascia (figure 1). Subsequently a full thickness biopsy of the musculus flexor digitorum superficialis was performed, revealing an inflammatory infiltration of lymphocytes and eosinophils, localized in the fascia. There was no necrosis of muscle fibers. No signs of scleroderma were found. The biopsy confirmed the diagnosis of eosinophilic fasciitis. Clinical and MRI findings suggested an early stage of disease and the patient was treated with lowdose corticosteroids.
