The idiopathic interstitial pneumonias are diffuse lung diseases characterized by interstitial inflammation and fibrosis. High resolution computed tomography (HRCT) is the best imaging technique for the study of interstitial disease.

The general term “idiopathic interstitial pneumonia” includes usual interstitial pneumonia/idiopathic pulmonary fibrosis, nonspecific interstitial pneumonia, desquamative interstitial pneumonia, respiratory bronchiolitis-associated interstitial lung disease, cryptogenic organizing pneumonia, acute interstitial pneumonia, and lymphocytic interstitial pneumonia.

The radiologist's role consists of identifying the macroscopic morphological pattern and working together with clinicians and pathologists to generate an integrated clinical diagnosis. The objective of this article is to review the idiopathic interstitial pneumonias and to describe their different manifestations in HRCT.

Las neumonías intersticiales idiopáticas son enfermedades pulmonares difusas caracterizadas por inflamación intersticial y fibrosis. La tomografía computarizada de alta resolución (TCAR) es la mejor técnica de imagen para estudiar las enfermedades intersticiales.

Bajo el término general «neumonía intersticial idiopática» se incluyen a la neumonía intersticial usual/fibrosis pulmonar idiopática, la neumonía intersticial no específica, la neumonía intersticial descamativa, la bronquiolitis respiratoria asociada a enfermedad intersticial pulmonar, la neumonía organizada, la neumonía intersticial aguda y la neumonía intersticial linfocítica.

El papel del radiólogo consiste en identificar el patrón morfológico macroscópico y trabajar conjuntamente con el clínico y patólogo para generar un diagnóstico clínico integrado. El objetivo de este trabajo es realizar una revisión de las neumonías intersticiales idiopáticas y describir sus diferentes manifestaciones en la TCAR.
