The 'folded lung' (Blesovsky syndrome)

A lesion of the pleura and of the confines of the lung, which consists of a thickened pleura beneath which there is an area of folded, round- or comet-shaped atelectatic lung. Asbestos is a classic and common cause for it. Ergots are the exemplar family of drugs that may cause it
