Calcific tendinosis and periarthritis: classic magnetic resonance imaging appearance and associated findings.

Calcification within tendon and periarticular soft tissues with or without a history of pain is commonly encountered in the interpretation of musculoskeletal MR imaging (MRI) studies. This article presents a pictorial illustration of both the classic and atypical MR imaging (MRI) features of soft tissue calcifications in the musculoskeletal system. Familiarity with this topic can help to avoid pitfalls in imaging diagnosis.
