Hypercapnic coma due to diaphragmatic involvement in a patient with dermatomyositis

Abstract

We report an acute respiratory distress by diaphragmatic involvement due to dermatomyositis. A fifty year-old patient with typical dermatomyositis presented an acute respiratory insufficiency with hypercapnic coma due to diaphragmatic muscle involvement. Respiratory state required mechanical ventilation initially and improved secondarily gradually upon corticosteroids and intravenous immunoglobulins. Only few cases of acute respiratory distress in dermatomyositis due to respiratory muscle involvement are reported in literature.
