[The radiological findings in poisonings by metals].

We present four cases of heavy metal poisoning (mercury, lead, bismuth and arsenic) in which plain chest and/or abdominal assisted in the differential diagnosis of the clinical picture manifested upon admission at our Emergency Department. The patients suffering from mercury, lead, and bismuth poisoning recovered some weeks after treatment was started. However, the patient with arsenic trioxide poisoning developed cardio-circulatory collapse leading to death three days after admission.
