Round pneumonia is seen with:
Round pneumonia is seen with:
Show Hint
This spherical consolidation in children is most often caused by the pneumococcus.
Updated On: Jun 24, 2026
- Streptococcal pneumonia
- Kerosene oil aspiration
- Lung cancer
- Mendelson syndrome
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Round pneumonia describes a well-defined spherical area of consolidation, most often encountered in young children whose lungs lack mature collateral ventilation pathways, which keeps the infection confined and rounded.
Step 2: The classic causative organism is the pneumococcus, Streptococcus pneumoniae, which is why streptococcal pneumonia is the correct association.
Step 3: The distractors represent other lung processes: kerosene aspiration leads to hydrocarbon pneumonitis, Mendelson syndrome is acid-aspiration pneumonitis, and lung cancer is a neoplastic mass. The relevance of round pneumonia is that radiologically it can resemble a tumour and must be distinguished from one.
Step 4: Thus round pneumonia is linked to streptococcal pneumonia.
\[\boxed{\text{Streptococcal pneumonia}}\]
