Orthopedic manifestations, particularly bone infarctions, remain exceptional and unusual during polymyositis. They are classically related to systemic corticosteroids or other associated thrombotic conditions. We report an original observation of bilateral distal femoral bone infarction revealing polymyositis in a 42-year-old woman. Our observation is, to the best of our knowledge, the first to report bilateral femoral infarction as a possible manifestation of polymyositis apart from any prolonged corticosteroid therapy and any associated anti-phospholipid antibody syndrome.
