CTICasesAcute eosinophilic pneumonia
Imaging findings
Chest CT in a pregnant woman who underwent IVF shows peripheral septal lines, dependent ground-glass opacities, and consolidations. Bronchoalveolar lavage confirmed acute eosinophilic pneumonia, which was triggered by intramuscular progesterone injections in a sesame oil base.
Key takeaways
Acute eosinophilic pneumonia can be triggered by medical drug administrations, including intramuscular progesterone injections formulated in sesame oil. Differentiating this drug-induced iatrogenic complication from other infectious or cardiorespiratory processes is vital, as it is highly responsive to steroids.
