How many cranial CT scans does a man need?

A 61-year-old man had epilepsy related to chronic alcoholism and occipito-temporal porencephaly. Over a span of 19 years, he had been admitted to our institution 227 times, undergoing 55 CT scans of the head and 11 CT scans of the cervical spine. His blood alcohol concentrations varied between 1.9 g/L and 5.1 g/L. We discuss the challenges of emergency management of patients with alcoholism and seizures and the overuse of radiological examinations.
