Diagnosis

Exogenous lipoid pneumonia

Radiologic Findings

On initial chest radiograph and CT, diffuse, ill-defined ground-glass opacities were noted in bilateral lungs. Those findings are spontaneously resolved on follow up chest radiograph and CT after 4 months. However, after 3 months, ill-defined ground-glass opacity was reappeared in a similar distribution.

Brief Review

The patient took omega-3 (fish oil) capsule for years, which contains oil.
Lipoid pneumonia results from chronic aspiration or inhalation of animal, vegetable or fish oil or fat over period. It is uncommon entity and has been reported in 1.0
