Statin-associated focal myositis

Abstract

Myositis is an infrequent side effect of statin therapy, usually presenting as diffuse myositis with muscle weakness and cramping involving multiple body parts. We report a case of focal myositis of a hip muscle diagnosed on magnetic resonance imaging, as the underlying pathology was suspected to be related to an orthopaedic disease due to isolated hip symptoms, and which was finally attributed to statin intake. Awareness to this rare cause of musculoskeletal symptoms is indicated in case a patient presents with probable orthopaedic disease and is on statin therapy.
