CTICasesRound Pneumonia
Imaging findings
Chest radiograph shows a well-defined, round mass-like opacity in the right upper lobe mimicking a neoplasm. CT chest demonstrates a larger, more ill-defined region of consolidation with internal air bronchograms and surrounding ground-glass halo, which cleared completely after antibiotic therapy.
Key takeaways
Round pneumonia is a form of acute bacterial pneumonia that presents as a spherical consolidation. Although more common in children due to underdeveloped collateral ventilation pathways, it can occur in adults and must be differentiated from pulmonary neoplasms, vasculitis, or fungal infections by verifying resolution on follow-up imaging after antibiotics.
