29. GROUND-GLASS OPACITY

33. MOSAIC ATTENUATION.

49. Left Upper lobe pneumonia.

51. Radiation pneumonitis in right lung.

52. Bilateral multilobar pneumonia.

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

54. Focal organizing pneumonia.

58. Pulmonary edema due to hypertensive heart disease.

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

60. Granulomatous vasculitis and pulmonary hemorrhage: bilateral,
confluent parenchymal consolidations and ground-glass opacities
predominantly distributed in the upper lobes, associated with nodules.

61. ARDS.

62. Acute interstitial pneumonia.

63. Lymphocytic interstitial pneumonitis.

64. Eosinophilic pneumonia.

65. Post-radiation pneumonia.

66. Hypersensitivity pneumonitis.

67. Sarcoidosis with
pulmonary and
mediastinal
involvement.

68. 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).

69. 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”

70. Pulmonary Alveolar Proteinosis

71. Pulmonary Alveolar Proteinosis

72. 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.

73. 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).

76. PLEURAL EFFUSION.

78. High-resolution CT findings correlated with pathology. (A) High-resolution CT findings corresponding to exudative phase of acute
respiratory 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).

79. CT scan with ARDS caused by severe bronchopneumonia.

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

82. Broncho-alveolar carcinoma.

83. Broncho-alveolar carcinoma.

87. CENTRILOBULAR NODULES

93. PERILYMPHATIC NODULES.

94. RANDOMLY DISTRIBUTED NODULES

105. AIR TRAPPING

106. BRONCHIECTASIS

107. HONEYCOMBING

108. TREE-IN-BUD
