Unilateral pulmonary fibrosis associated with a contralateral epiphrenic diverticulum--support for a hypothesis

A case of predominantly unilateral pulmonary fibrosis associated with a contralateral epiphrenic oesophageal diverticulum is reported. This experiment of nature is offered to support the hypothesis that cryptogenic fibrosing alveolitis (idiopathic pulmonary fibrosis) may in some instances be due to repeated aspiration of gastroesophageal contents.
