[Extrapyramidal syndrome after cardiocirculatory incompetence].

A 43 year-old woman suffered a cardio-circulatory arrest with a post-anoxic coma during 24 hours. This was followed by and akinetic-hypertonic syndrome. There was also dystonia of both hands and of right big toe. After and initial mutism, the patient spoke with dysarthria, a monotonous weak voice of poor timbre and low vocal volume. She had in addition mood disturbances with indifference to her condition and compulsive activity. Extrapyramidal syndromes after ischemic anoxia are rare, when compared to their relative frequency after carbon monoxide poisoning. Early CT scan with contrast can identify symmetrical and bilateral lenticulocaudal high densities and MRI is also useful for the diagnosis.
