Eosinophilic fasciitis (EF), also known as Shulman syndrome, is a rare scleroderma-like disorder that is characterized by an acute onset of induration, swelling, erythema, and tenderness of the skin and deep fascia, often affecting all four limbs. We report a case of eosinophilic fasciitis in a 51-year-old female patient, whose diagnosis of EF was made based on the findings from clinical evaluation and magnetic resonance imaging (MRI) but without skin biopsy. She was treated with a combination therapy of prednisolone and methotrexate, and her response to therapy was assessed via clinical assessment and MRI. MRI may be a useful non-invasive diagnostic tool for not only supporting but also confirming the clinical diagnosis of EF when a skin-to-muscle biopsy is not available or cannot be performed, as well as for monitoring disease activity and response to therapy. Further prospective studies should be conducted to evaluate the precise sensitivity and specificity of MRI in diagnosing EF and also to create more structured protocols to guide the diagnosis and management of EF.
