King Syndrome; A Case Report

Abstract

We report one case of King syndrome with myopathy, dysmorphic features, and malignant hyperthermia. The patient was a 1-year-old boy.
Accessory ears, low set ears and a high arched palate were present. There was no family history of malignant hyperthermia.
The patient's body temperature rose rapidly during the resection of his accessory ears while under inhalational anaesthetics. We then performed an intravascular injection with dantrolene. The patient recovered after four days without sequelae.
