Spontaneous epidural air entrapment.

BACKGROUND:Epidural pneumorrhachis (EPR), an extension of pneumomediastinum, results from air that leaks from the mediastinum and accumulates in the epidural space of the spine. It is an uncommon, benign condition; most cases are asymptomatic, are recognized only on computed tomography scans, and require no treatment. CASE REPORT:We present a case of EPR, pneumomediastinum, pneumothorax, and subcutaneous emphysema in a young male who was managed conservatively with supportive care. CONCLUSIONS:EPR is a rare yet benign condition that can be found incidentally while working up lung or spine pathology. Although radiography can define the presence of a pneumomediastinum and subcutaneous emphysema, the diagnosis of EPR can only be made using computed tomography. The management of EPR is usually conservative, and the focus should be on underlying disease.
