Pneumonia, Bacterial

FIGURE 13-5 Classic appearance of a Gram stain of sputum from a patient with pneumococcal pneumonia. The smear shows lancet-shaped diplococci with polymorphonuclear leukocytes, and no other prominent bacterial morphology is present.

FIG. 11.26. A child with bacterial pneumonia. This radiograph of the chest shows a lobar consolidation and a pleural effusion on the right. Note the meniscus indicating the presence of fluid in the pleural cavity.

FIG. 11.27. Pneumonia with large pleural effusion. This child presented with bacterial pneumonia and respiratory distress, presumed to be caused in part by the large pleural effusion. In the emergency department, a pleural catheter ("pigtail") was placed for drainage, using the Seldinger technique.

FIG. 11.61. Varicella pneumonia. Severe pneumonia developed in this patient shortly after she developed vesicular skin lesions that were positive for varicella-zoster virus by direct fluorescent antibody. Varicella causes a diffuse, miliary pattern.

FIGURE 13-1 Chest radiograph showing homogeneous consolidation involving the right upper and middle lobes. The air spaces of the lobes are filled with liquid.
