Round Pneumonia

Key Points:

Round pneumonia could have variable sizes and appears classically in the posterior portions of the lower lobes. This process respects the lobar anatomy and does not cross fissures. An air bronchogram could also be occasionally seen. The disease could spread to become lobar in nature.

(1) If a child has symptoms of pneumonia in conjunction with a round opacity on a chest radiograph, the diagnosis is round pneumonia and no CT evaluation is initially needed.
(2) A follow-up several weeks after treatment is needed to ensure resolution.
