We describe an interesting case of pneumomediastinum secondary to cocaine abuse. The patient presented with severe chest pain following nasal inhalation of a large quantity of cocaine. Investigations revealed no chest injury; however oesophagitis was proven leading to a possible aetiology of oesophageal microperforation. After conservative management there was spontaneous resolution of the pneumomediastinum.
