A conundrum arises when widespread small opacities are difficult to categorize into one group or the other on chest radiography, or when ILD and ALD are both present. Webb WR, Higgins CB. (a) UIP is characterized by heterogeneous lung abnormalities consisting of subpleural honeycombing (arrowhead), reticular opacities, and traction bronchiectasis. This should be considered in the presence of basal subpleural reticular predominant abnormalities, where honeycombing is absent and where there is an absence of atypical features. Follow-up with chest CT would be warranted in 3 months, per Fleischner Society guidelines for management of solid pulmonary nodules.

Subpleural opacities and Ground glass opacities. viral; mycoplasma; Pneumocystis; malaria; drug reactions; predominantly reticular: chronic. Subpleural reticulation is a type of reticular interstitial pattern where the changes are typically in a peripheral subpleural distribution (i.e. ... n=30). Usual interstitial pneumonia. 18 years experience Interventional Radiology. Nonspecific interstitial pneumonia and idiopathic pulmonary fibrosis: changes in pattern and distribution of disease over time. She had bilateral polyphonic wheezes. A large group of morphological changes seen on HRCT in interstitial lung disease are linear and reticular opacities. She was started on Albuterol as needed and Salmeterol-fluticasone MDI. On chest CT we found two attributes: (b) NSIP demonstrates homogeneous lung involvement with predominance of ground-glass opacity combined with sub-pleural linear opacities and micronodules. A chest X Ray was done which came out to be normal.

Gotway MB, Freemer MM, King TE. It can arise in a number of pathological situations as well as in certain physiological situations. heart failure; fluid overload; nephropathy; infection. Now after 4 months, she still had cough and shortness of breath. HRCT obtained during the accelerated phase of the disease demonstrates a generalized increase in lung attenuation and progression of both the reticular and … In early UIP, chest radiographs may be normal, whereas in advanced disease there are decreased lung volumes and subpleural reticular opacities that increase from the lung apices to the bases . Subtle diffuse ground glass centrilobular nodules. The reticulation was fine or coarse, and was unassociated with honeycombing or … Ground-glass opacities have a broad etiology: 1. normal expiration 2. partial filling of air spaces 3. partial collapse of alveoli 4. interstitial thickening 5. inflammation 6. edema 7. fibrosis 8. lepidic proliferationof neoplasm 1. focal ground-glass opacification 2. diffuse ground-glass opacification 3. isolated diffuse ground-glass opacification 5 2007;62 (6): 546-53.

Thickening of the lung interstitium by fluid, fibrous tissue, or infiltration by cells results in a pattern of reticular opacities due to thickening of the interlobular septa. (C) Day 20: expansion of bilateral pulmonary lesions, with enlargement and denser pulmonary consolidations and bilateral pleural effusions (arrows). adjacent to costal pleural surfaces, located ≤1 cm from the pleura according to some publications 4). Focal airspace disease.
