OBJECTIVE: The purpose of this article is to explore the role of MRI in monitoring musculoskeletal involvement in patients with morphea who are undergoing treatment with methotrexate and prednisolone.
SUBJECTS AND METHODS: Twenty-two consecutive patients (six men and 16 women; median age, 52 years) with systemic scleroderma and deep morphea prospectively underwent whole-body MRI twice, before treatment (time 1) and during follow-up after 6-12 months (time 2). Images were evaluated for abnormal signal intensity or thickening of sub-cutaneous fatty tissue septa, muscular fasciae, intramuscular perifascial septa, muscle signal intensity, and articular or tendon sheath synovial abnormalities on STIR and gadolinium-enhanced scans. For clinical assessment, the localized scleroderma (morphea) severity index and a 0-6 pain score were applied.
RESULTS: From a clinical point of view, none of our patients had progression of the disease, 12 patients were responders (defined as an improvement of localized scleroderma severity index and pain score ≥ 50%), and 10 patients had stable disease. Among responders, the number of patients with subcutaneous septal thickening (time 1, n = 9; time 2, n = 2), fascial enhancement (time 1, n = 8; time 2, n = 3), and articular synovitis (time 1, n = 5; time 2, n = 1) decreased more than in the stable disease group (subcutaneous septal thickening: time 1, n = 9; time 2, n = 8; fascial enhancement: time 1, n = 5; time 2, n = 5; articular synovitis: time 1, n = 8; time 2, n = 6). Subcutaneous thickening, fascial thickening, and fascial enhancement were scored significantly lower at follow-up MRI in responders.
CONCLUSION: MRI findings were sensitive to changes in musculoskeletal manifestations in patients with deep morphea undergoing systemic treatment with methotrexate and prednisolone. Thus, MRI can be recommended as an additional tool for response monitoring.
