ABSTRACT
Interstitial lung diseases cover a very wide group of diseases. In these diseases, high-resolution computed tomography (CT) plays an important place in the diagnosis. For the correct diagnosis of interstitial lung diseases, knowing the anatomy of the interstitium and correct interpretation of the CT patterns created by these diseases and their combinations have a key role. Major CT patterns can be classified as ground glass, consolidation, nodular pattern, reticular and linear pattern, traction bronchiectasis, honeycomb lung, air cysts, and mosaic perfusion and attenuation. The presence and distribution of these patterns, as well as other accompanying findings, as well as clinical and other laboratory findings, are important for differential diagnosis.
