Reticular interstitial pattern
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.
Pathology
Causes
Reticulation can be subdivided by the size of the intervening pulmonary lucency into fine, medium and coarse. Diseases with a predom...

Reticular and linear pulmonary opacification
In chest radiology, reticular and linear opacification refers to a broad subgroup of pulmonary opacification caused by a decrease in the gas to soft tissue ratio due to a pathological process centered in or around the pulmonary interstitium. This includes thickening of any of the interstitial co...

Subpleural reticulation
Subpleural reticulation is a type of reticular interstitial pattern where the changes are typically in a peripheral subpleural distribution (i.e. adjacent to costal pleural surfaces, located ≤1 cm from the pleura according to some publications 4).
Pathology
It can arise in a number of patholog...

Usual interstitial pneumonia
Usual interstitial pneumonia (UIP) is not a disease, it is a histopathologic and radiologic pattern of interstitial lung disease. This can be caused by idiopathic pulmonary fibrosis, fibrotic hypersensitivity pneumonitis or non-specific interstitial pneumonia. The diagnosis is typically decided ...

Acute respiratory distress syndrome
Acute respiratory distress syndrome (ARDS) is a form of acute lung injury and occurs as a result of a severe pulmonary injury that causes alveolar damage heterogeneously throughout the lung. It can either result from a direct pulmonary source or as a response to systemic injury.
This is a disti...

Ground-glass opacification
Ground-glass opacification/opacity (GGO) is a descriptive term referring to an area of increased attenuation in the lung on computed tomography (CT) with preserved bronchial and vascular markings. It is a non-specific sign with a wide etiology including infection, chronic interstitial disease an...

Autoimmune hepatitis
Autoimmune hepatitis (AIH) (plural: autoimmune hepatitides) is a rare type of chronic hepatitis, classified as "type 1" or "type 2". It may eventually lead to cirrhosis. The role of imaging is primarily to exclude other diagnoses and evaluate for complications.
Epidemiology
It may occur in chi...

Goodpasture syndrome
Goodpasture syndrome, also referred as antiglomerular basement membrane (anti-GBM) antibody disease, is an autoimmune disease characterized by damage to the alveolar and renal glomerular basement membranes by a cytotoxic antibody. It is a type of pulmonary-renal syndrome.

Idiopathic pulmonary fibrosis
Idiopathic pulmonary fibrosis (IPF) is a clinical syndrome and considered the most common and the most lethal form of pulmonary fibrosis corresponding to the histologic and imaging pattern of usual interstitial pneumonia. It is more common in elderly men and diagnosed by:
