Reticular interstitial pattern

Last revised by Bashar Karkoush on 22 Jul 2022

Reticular interstitial pattern is one of the patterns of linear opacification in the lung. It can either mean a plain film or HRCT/CT feature. 



Reticulation can be subdivided by the size of the intervening pulmonary lucency into fine, medium and coarse. Diseases with a predominantly reticular pattern can be subdivided by the acuteness of their presentation.
