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).
It may also be classified by the area of the lung affected: lobar, bronchial pneumonia and acute interstitial pneumonia; [42] or by the causative organism. [82] Pneumonia in children may additionally be classified based on signs and symptoms as non-severe, severe, or very severe. [83]
A lobar pneumonia is an infection that only involves a single lobe, or section, of a lung. Lobar pneumonia is often due to Streptococcus pneumoniae (though Klebsiella pneumoniae is also possible.) [16] Multilobar pneumonia involves more than one lobe, and it often causes a more severe illness.

Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 1 ] [ 2 ] [ 3 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
Walking pneumonia, a lung infection caused by the bacterium Mycoplasma pneumoniae, tends to be most common among older children and adolescents but in 2024 has been rampant among young children.
