Hemorrhagic Pneumonia
The gross pathology specimen shows a hemorrhagic lobar pneumonia (red hepatisation) in the left upper lobe with patchy subsegmental bronchopneumonic disease in the lower lobe. The relationship to the surface pleura may result in pleuritic pain.

Multifocal Pneumonia
45-year-old immunocompromised male presents with a cough fever and shock.
Portable frontal CXR shows a multifocal pneumonic consolidations with air bronchograms in the right upper, left upper right lower and left lower lobes, magnified in the surrounding images. There is silhouetting of the right heart border reflecting middle lobe involvement. The patient is intubated with an intra-aortic balloon pump (IABP) and Swan Ganz line.

Lobar Pneumonia with a Filling Defect in the Pulmonary Vein
The upper panels are imaged during early pulmonary venous phase and show a “filling defect” in the left lower lobe pulmonary vein in the axial and coronal reconstruction of a CT scan. The lower panels are in equilibrium phase and show normal opacification. The “filling defect” in the upper panels is caused by a delay in opacification (ie blood flow) to the left lung because the poor ventilation in the left lung has resulted in a decreased perfusion and therefore there is unopacified blood in the left lower lobe pulmonary veins. The right lung is normal and pulmonary veins are opacified normally. The lower panels are in the later equilibrium phase of contrast opacification, and by this time they have become opacified with contrast confirming the absence of a suspected thrombus in the left lower lobe pulmonary vein.

Infection Inflammation
Acute Aspiration Pneumonia on Chronic Interstitial Lung Disease
55-year-old female with shortness of breath. CT (above) is from 4 years prior and shows an interstitial process characterized by ground glass and reticular change. The patient presents 4 years later with fever and white count and the CT (below) shows a pneumonic process in a background of ac chronic interstitial process with cystic air spaces and architectural distortion. Aspiration pneumonia was considered most likely

71 yo m w/ a hx of recently diagnosed ANCA-associated vasculitis (diagnosed by kidney biopsy), presents with acute respiratory failure. Bronchoscopic findings were consistent with diffuse alveolar hemorrhage associated with MSSA (Methicillin Sensitive Staph Aureus ) pneumonia/bacteremia. Note Consolidation surrounded by ground glass opacity, the latter likely reflecting a hemorrhagic component
CTscan shows multicentric consolidations likely a combination of alveolar hemorrhage and pneumonia
