Magnetic resonance imaging in the evaluation of patients with eosinophilic fasciitis.

: Two cases of eosinophilic fasciitis are described, in which magnetic resonance imaging (MRI) clearly demonstrated thickening of the fascia and increased signal intensity in the superficial muscle fibers correlating with inflammation. MRI is a useful noninvasive imaging technique in the diagnosis of eosinophilic fasciitis and can guide biopsy of selected abnormal areas.
