Two cases of spontaneous epidural emphysema during asthmatic attack

Two cases of spontaneous epidural emphysema that occurred during asthmatic attacks in a 13-year-old and a 15-year-old are reported here. Epidural emphysema was diagnosed in both cases by using computed tomography (CT), and in 1 case by using magnetic resonance imaging (MRI). Neither patient had neurological findings. Both patients were discharged with no respiratory difficulties. It is generally believed that a diagnosis of epidural emphysema can only be made on CT. In this report, MRI was used to make the diagnosis of subdural emphysema, and it demonstrated that the air was localized within the epidural fat.
