Iodide-Induced Severe Encephalopathy: A Case Report and Literature Review.

A physically independent and mentally competent 61-year-old gentleman was diagnosed with left upper alveolar spindle cell carcinoma. He underwent left infrastructure maxillectomy with reconstruction and had bismuth iodoform paraffin paste packed in the post-operative cavities. The patient subsequently exhibited labile emotions and acute delirium. Further investigation showed that his urine iodine level was highly elevated. He eventually made a full recovery and returned home.
