Case #14


Findings

  • Masslike airspace opacity in the superior segment of the right lower lobe measuring approximately 7 x 6 x 6 cm


Diagnosis

  • Round pneumonia

Sample Report

Masslike airspace opacity in the superior segment of the right lower lobe measuring approximately 7 x 6 x 6 cm, for which the primary consideration is round pneumonia. Recommend followup radiographs 2-3 weeks after treatment to ensure resolution.

No pleural effusion or pneumothorax.

Normal size and contour of the cardiopericardial silhouette.


Discussion

  • Round pneumonia predominantly occurs in pre-adolescent children, in whom underdeveloped pores of Kohn (interalveolar communications) and channels of Lambert (communications between terminal bronchioles and alveoli) limit spread of infection throughout the lobe
  • The masslike appearance of these infections can be difficult to distinguish from a neoplasm on radiographs, so followup radiographs are usually obtained to ensure resolution
  • Round pneumonias usually do not have associated pleural effusions and should not have cavitation


Images

This patient did get a CT which confirms the area of masslike consolidation consistent with round pneumonia Followup radiograph in 2 weeks shows near complete resolution of the radiographic abnormality.
