Marijuana lung: radiological, macroscopic and histopathological triptych

“Marijuana lung” refers to a radiological-pathological entity of apical (bullous) paraseptal emphysema in persons who regularly smoke cannabis. We describe a post-mortem case of a drowned young man in whom apical bullous emphysema was seen on post-mortem computed tomography (PMCT) as an incidental finding. Histopathology confirmed the existence of apical paraseptal emphysema. Toxicology, including hair analysis, confirmed that he was a chronic cannabis user. As such this case report can be supportive of the association between chronic cannabis use and the development of paraseptal emphysema.
