Influenza A pneumonia
This case illustrates and shows the most common findings of influenza A pneumonia a combination of multifocal ground-glass opacities (GGO) and irregular consolidations, mainly along and around the bronchovascular bundles.
Real-time polymerase chain reaction (PCR) after respiratory swab was positive for influenza A virus RNA.
The patient was put under isolation and received supportive and antiviral therapy (oseltamivir) and an antibiotic regimen covering for gram-positive cocci for 7 days. After a hospital course of 8 days, the patient recovered and was released home in a vastly improved condition.
Outpatient follow-up CT, three weeks later, was normal and showed complete resolution of the ground glass opacities (GGO) and consolidations.
This is also an important differential diagnosis for COVID-19 pneumonia.
