Lobar pneumonia is a form of pneumonia that affects a large and continuous area of the lobe of a lung.[1]

It is one of the two anatomic classifications of pneumonia (the other being bronchopneumonia).

Stages[edit]

Lobar pneumonia usually has an acute progression. Classically, the disease has four stages:

Diagnosis[edit]

Lobar pneumonia of the middle lobe. (Notice sharp edges)

The most common organisms which cause lobar pneumonia are Streptococcus pneumoniae, also called pneumococcus, Haemophilus influenzae and Moraxella catarrhalis. Mycobacterium tuberculosis, the tubercle bacillus, may also cause lobar pneumonia if pulmonary tuberculosis is not treated promptly.

The identification of the infectious organism (or other cause) is an important part of modern treatment of pneumonia. The anatomical patterns of distribution can be associated with certain organisms,[2] and can help in selection of an antibiotic while waiting for the pathogen to be cultured.
