Abstract
Abstract Immune‐mediated necrotizing myopathy (IMNM) is an idiopathic inflammatory myopathy characterized by limb weakness, markedly elevated serum creatine kinase (CK), and muscle fiber necrosis without lymphocytic infiltration. Here, we present a case of IMNM that developed during pregnancy. The patient was treated immediately with systemic corticosteroids, and muscle weakness and serum CK levels were improved without adverse effects on the pregnancy. As there are only a few reports of IMNM during pregnancy, the clinical course and treatment of IMNM during pregnancy are discussed with a review of the literature.
