Acute hydrocarbon pneumonia after white spirit aspiration: sequential HRCT findings.

Hydrocarbon pneumonia is a very uncommon condition resulting from aspiration of mineral oil into the lung. We report the first description of early and sequential high-resolution computed tomographic (HRCT) findings of hydrocarbon pneumonia following attempted suicide by white spirit aspiration. Initial HRCT showed patchy opacities of coalescing masses with well-defined walls. They were visible in the middle lobe, lingula and lower lobes. Follow-up CT showed regression of the alveolar opacities, the presence of pneumatoceles and right asymptomatic pneumothorax. After 23 months of follow-up, the patient remained asymptomatic, and the follow-up CT scan was considered normal. The radiological features and a review of the relevant literature are briefly discussed.
