MR findings in the arthropathy of relapsing polychondritis

摘要

We report a case of relapsing polychondritis involving three synovial joints in a child. Initial presentation was at 5 years of age with periorbital edema and chemosis of the conjunctiva with a definite diagnosis established at 9 years of age following an acute monoarticular arthropathy of the knee. The role of MRI in suggesting the diagnosis of relapsing polychondritis is emphasized by demonstrating a unique pattern of inflammation and enhancement that preferentially involves the perichondrium and chondroepiphysis.
