Eosinophilic fasciitis (EF) is an uncommon connective tissue disease. We report a patient with EF who presented with episodic swelling and stiffness of his legs and forearms in combination with peripheral eosinophilia. Imaging studies of the legs and forearms, including computed tomography (CT) and magnetic resonance imaging (MRI), clearly demonstrated the characteristic finding of fascial thickening. The complete clinical imaging and pathological findings are described in this report. Cross-sectional imaging is useful in diagnosing EF and in the appropriate clinical scenario may be helpful in differentiating EF from other connective tissue diseases.
