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.

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. Acute Pulmonary Consolidation; … adjacent to costal pleural surfaces, located ≤1 cm from the pleura according to some publications 4). On HRCT, a confident diagnosis of IPF is based on the presence of bilateral, predominantly subpleural, and basal reticular opacities with associated traction bronchiectasis and honeycombing in the absence of small nodules or extensive ground-glass opacity ...

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 . (B) Day 15: subpleural crescent-shaped ground-glass opacities in both lungs, as well as posterior reticular opacities and subpleural crescent-shaped consolidations. In advanced disease, the chest radiograph shows decreased lung volumes and subpleural reticular opacities that increase from the apex to the bases of the lungs (, 14).

Subpleural reticulation is a type of reticular interstitial pattern where the changes are typically in a peripheral subpleural distribution (i.e. (a) UIP is characterized by heterogeneous lung abnormalities consisting of subpleural honeycombing (arrowhead), reticular opacities, and traction bronchiectasis. adjacent to costal pleural surfaces, located ≤1 cm from the pleura according to some publications 4 ).

A large group of morphological changes seen on HRCT in interstitial lung disease are linear and reticular opacities. In NSIP, ground glass opacity is the main feature associated with fine subpleural reticulations (thickening of the intralobular septa), traction bronchiectasis and bronchiolectasis, with no apical-basal gradient. 2. 3. Pulmonary embolism with resultant subpleural pulmonary infarction, 4. Although thickening of the interlobular septa is relatively common in patients with interstitial lung disease, it is uncommon as a predominant finding and has a limited differential diagnosis (Table).

Inhalation of toxic fumes and gases can cause pulmonary damage, depending on the specific toxic agent and the duration of exposure. These opacities do not make contact with the pleura or fissures (Fig. Eosinophilic granulomatosis with polyangiitis( previously called Churg Strauss). Pneumonia; Pulmonary embolism: infarction or intrapulmonary hemorrhage; Neoplasm: alveolar cell carcinoma, lymphoma (usually … 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. The right upper lobe subpleural nodular opacity was not hypermetabolic, favoring a benign etiology. what does this mean to me ? (b) NSIP demonstrates homogeneous lung involvement with predominance of ground-glass opacity combined with sub-pleural linear opacities and micronodules. 25 years experience Pulmonology. CT typically reveals a subpleural and symmetric distribution of ground-glass opacities combined with fine reticular opacities and micronodules . ... n=30).
