Reticular interstitial pattern

Last revised by Dr 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.
