Lobar pneumonia is a form of pneumonia characterized by inflammatory exudate within the intra-alveolar space resulting in consolidation that affects a large and continuous area of the lobe of a lung. [1] [2] It is one of three anatomic classifications of pneumonia (the other being bronchopneumonia and atypical pneumonia).
Signs that consolidation may have occurred include: Expansion of the thorax on inspiration is reduced on the affected side; Vocal fremitus is increased on the affected side; Percussion note is impaired in the affected area; Breath sounds are bronchial; Possible medium, late, or pan-inspiratory crackles; Vocal resonance is increased.
X-ray presentations of pneumonia may be classified as lobar pneumonia, bronchopneumonia, lobular pneumonia, and interstitial pneumonia. [75] Bacterial, community-acquired pneumonia classically show lung consolidation of one lung segmental lobe, which is known as lobar pneumonia. [42]
In some cases, chest CT can reveal pneumonia not seen on x-rays. However, congestive heart failure or other types of lung damage can mimic CAP on x-ray. [15] When signs of pneumonia are discovered during evaluation, chest X-rays and examination of the blood and sputum for infectious microorganisms may be done to support a diagnosis of CAP.
Both doctors say that the people most at risk for pneumonia include those over the age of 65, those with weakened immune systems, and those with other medical conditions, including lung disease ...
Silhouette sign; A) Normal chest radiograph; B) Q fever pneumonia affecting the right lower and middle lobes. Note the loss of the normal radiographic silhouette (contour) between the affected lung and its right heart border as well as between the affected lung and its right diaphragm border. This phenomenon is called the silhouette sign
Pneumococcal pneumonia is a type of bacterial pneumonia that is caused by Streptococcus pneumoniae (pneumococcus). [1] It is the most common bacterial pneumonia found in adults, the most common type of community-acquired pneumonia, and one of the common types of pneumococcal infection. The estimated number of Americans with pneumococcal ...
