Zusammenfassung:The crazy-paving pattern found on computed tomography of the lungs is a nonspecific radiologic sign named after the appearance of paths made with pieces of stone or concrete. It was first described in the late 1980s in patients with pulmonary alveolar proteinosis, but has now been described in association with at least 15 pulmonary diseases.1 Histologically, three processes lead to the crazy-paving pattern: an alveolar filling process, interstitial fibrosis and a combination of the two. The lung insults associated with these processes can be related to infection, neoplasm, inhalation, toxins and fluid overload, and can also be idiopathic.2
