[Encephalopathy and cerebellar calcifications from lead poisoning]

In a male and female couple hospitalized the former for exploration of a painful abdominal syndrome with encephalopathy, the latter at the end of an epileptic attack, the presence of cerebellar calcifications in unusual locations led to the demonstration of a domestic lead poisoning of dietary origin. The problems raised by the laboratory diagnosis and the inadequacy of static assays are underlined; in some cases, the EDTA test was the only means to confirm the toxicity. The arguments in favour of a relation between lead poisoning and cerebellar calcifications are developed.
