Primary spontaneous pneumothorax is mainly caused by the rupture of a small subpleural emphysematous vesicle (designated a bleb) or of a subpleural paraseptal emphysematous lesion (designated a bulla). The aim of this pictorial essay was to improve the understanding of primary spontaneous pneumothorax and to propose a description of the major anatomical lesions found during surgery.<\/jats:p>","DOI":"10.1590\/s1806-37562015000000230","type":"journal-article","created":{"date-parts":[[2016,7,2]],"date-time":"2016-07-02T10:49:04Z","timestamp":1467456544000},"page":"222-226","source":"Crossref","is-referenced-by-count":17,"title":["Etiology
