GROUND-GLASS OPACITY

MOSAIC ATTENUATION.

Left Upper lobe pneumonia.

Radiation pneumonitis in right lung.

Bilateral multilobar pneumonia.

Chronic eosinophilic pneumonia (left) versus Organizing pneumonia (right)

Focal organizing pneumonia.

Pulmonary edema due to hypertensive heart disease.

Pulmonary hemorrhage (recurrent hemoptysis): CT study demonstrates bilateral areas of ground-opacities having medullary distribution within the upper lobes.

Granulomatous vasculitis and pulmonary hemorrhage: bilateral, confluent parenchymal consolidations and ground-glass opacities

predominantly distributed in the upper lobes, associated with nodules.

ARDS.

Acute interstitial pneumonia.

Lymphocytic interstitial pneumonitis.

Eosinophilic pneumonia.

Post-radiation pneumonia.

Hypersensitivity pneumonitis.

Sarcoidosis with pulmonary and mediastinal involvement.

Lymphangitic carcinomatosis. A central bronchogenic carcinoma (blue arrow) is producing unilateral interstitial edema (blue circles) characteristic of lymphangitic carcinomatosis with a pleural effusion (red arrow), thickening and irregularity of the brochovascular bundles (yellow arrow) and thickening of the interlobular septa (light blue arrow).

Pulmonary Alveolar Proteinosis. There are areas of patchy ground-glass opacification with smooth interlobular septal thickening and intralobular interstitial

thickening (white circles) a polygonal pattern referred to as "crazy paving”

Pulmonary Alveolar Proteinosis

Pulmonary Alveolar Proteinosis

Cystic pneumocystis carinii pneumonia in a 48-year-old HIV-positive man presenting with shortness of breath and cough. (A) Posterioanterior chest radiograph shows numerous cysts of varying sizes with a diffuse distribution, but relative sparing of lung bases. (B) Coronal CT reformation image shows cysts to greater detail. Also note patchy foci of consolidation in the left upper lobe.

Pulmonary parenchymal lymphoma in a 41-year-old HIV-positive man. He presented with worsening shortness of breath and dry cough. (A) Chest radiograph reveals multiple poorly defined pulmonary nodules without lymphadenopathy. (B) CT image through the lower lobes shows an air bronchogram in the largest mass (arrow).

PLEURAL EFFUSION.

High-resolution CT findings correlated with pathology. (A) High-resolution CT findings corresponding to exudative phase of acuterespiratory distress syndrome (ARDS). HRCT scan at the level of right middle lobe shows dependent airspace consolidation without traction bronchiectasis and non-dependent areas of sparing. The patient was a 68-year-old man with ARDS due to Streptococcus pneumonia. (B) High-resolution CT findings corresponding to fibroproliferative phase of ARDS. HRCT scan at the level of right lower lobe shows extensive airspace consolidation and ground-glass attenuation associated with traction bronchiectasis (arrows). The patient was an 84-year-old woman with ARDS due to sepsis. (C) High-resolution CT findings corresponding to fibrotic phase of ARDS. HRCT scan at the level of right inferior pulmonary vein shows extensive ground-glass attenuation associated with traction bronchiectasis (arrows), coarse reticulation and cystic changes (arrowheads).

CT scan with ARDS caused by severe bronchopneumonia.

Asbestosis. High-resolution CT scan obtained with patient prone shows subpleural lines (arrows) parallel to inner chest wall. Note subpleural dot like opacities (arrowheads).

Broncho-alveolar carcinoma.
