Exogenous lipold pneumonia is an unusual disease resulting from aspiration of oil particles. A history of oil ingestion strongly suggests the diagnosis, but the radiological presentation varies from mild perihilar consolidation to diffuse and extensive bilateral involvement, particularly of the posterior basal segment of both lower lung(l). Since magnetic resonance(MR) provides greater contrast resolution than CT, it offers the potential for tissue characterization. In particular, fatty tissue and lipid containing substances are known to have high signal intensities on T1- and T2-weighted spin-echo (SE) images. We report MR findings in two case of exogenous lipold pneumonia caused by ingestion of shark liver oil(Squalene).
