-The chest radiograph appearances of pneumonia are not specific, and frank lobar consolidation as seen in adults and older children is rare. More commonly, there is coarse opacity of one or more regions of the lung parenchyma. However, these appearances can also be seen with retained fetal lung fluid, meconium aspiration, aspiration of gastric contents, and pulmonary haemorrhage. Pleural effusions are not uncommon in infection, but again may be seen with other conditions.

-Group B Streptococcus can have an appearance similar to Respiratory Distress Syndrome (Surfactant Deficiency), although the granulation is typically more coarse.
