Abstract

MARCHIORI, Edson et al. Lipoid pneumonia in adults: findings on high-resolution computed tomography. Radiol Bras [online]. 2007, vol.40, n.5, pp. 315-319. ISSN 1678-7099.  http://dx.doi.org/10.1590/S0100-39842007000500007.

OBJECTIVE: The present study was aimed at describing the findings on high-resolution computed tomography in patients with exogenous lipoid pneumonia secondary to mineral oil aspiration MATERIALS AND METHODS: Eight adult patients - four men and four women - with mean age of 69.4 years were studied. All of the patients were users of mineral oil for treating intestinal constipation. High-resolution computed tomography studies of these patients were blindly evaluated by two radiologists. RESULTS: Air-space consolidation with areas of fat density and crazy paving pattern were the most frequent findings. The lesions were bilateral in six cases and unilateral in two CONCLUSION: Air-space consolidation with areas of fat density, associated with a clinical history of mineral oil ingestion virtually indicates a diagnosis of exogenous lipoid pneumonia.
