[Interstitial pneumonias--Histopathological and radiological correlation].

Interstitial pneumonias comprise a group of lung diseases with overlapping clinical, radiological and pathological presentations. Because of the frequently non-discriminating clinical manifestation, correlation between radiology and pathology plays an important role. Multidisciplinary discussion is of utmost importance for establishing a valid diagnosis, and is considered a gold standard in the current 2002/2013 classification of idiopathic interstitial pneumonias. In the present work, we concisely review and illustrate the typical radiological and pathological pictures diagnostic for the most common (idiopathic) interstitial pneumonias.
