CTICasesNeutropenic Patient with Metapneumovirus
Imaging findings
Initially, the patient displayed sinusitis and dense basal opacities consistent with aspiration. Upon recovery of neutrophil counts, the patient developed patchy, peripheral-predominant lung consolidation consistent with organizing pneumonia.
Key takeaways
The organizing pneumonia pattern is often an immunologic response rather than a direct manifestation of the virus's location. A patient may need sufficient inflammatory cells (neutrophils) to mount this specific lung injury response.
