5-month-old male infant aspirated large amounts of paraffin oil causing respiratory distress diagnosed later as due to lipoid pneumonia (a) Chest computed tomography (CT) performed 1.5 month post-paraffin oil aspiration shows diffuse extensive airspace consolidations (arrows) in both lower lobes. (b) High-resolution chest CT taken 7 months after the incident shows persistent imaging findings (arrows) with minimal improvement.

Computed tomography (CT) scan [Figure 1a] revealed extensive bilateral consolidations in the lower lobes. Further, an additional CT scan was performed which showed persistent findings with minimal improvement [Figure 1b]. 7-years after the incident, the patient was admitted for a complete workup.
