[Malignant hyperthermia. Apropos of a case].

We present the clinical case of a thirteen-year-old male patient who suffered a malignant hyperthermia syndrome after an adenoidectomy under general anaesthesia. The recovery of the patient was successful with the specific treatment of dantrolene. We believe it is interesting to publish all the cases of malignant hyperthermia in order to have a better knowledge of the real incidence in our country.
