FRANK, L. et al. Embolia pulmonar grasa: Presentación de un caso. Rev. argent. radiol. [online]. 2015, vol.79, n.4, pp.209-213. ISSN 1852-9992.

Fat embolism (FE) may be defined as the blockage of blood vessels by fat globules. Pulmonary fat embolisms are reported to be associated with a wide variety of conditions, with the most common and important ones being with long bone fractures and soft tissue damage due to severe trauma. Fat embolism syndrome (FES) is a rare but serious manifestation of the fat embolism phenomenon, characterized clinically by a triad of dyspnea, petechiae, and mental confusión. The discrepancy between the presence of a fat embolism and the development of fat embolism syndrome is unclear. The case is presented of a 41 year-old mate who, on the initial trauma CT sean, presented with filling defeets of fat attenuation within the pulmonary arteries. Those were interpreted as múltiple macroscopic fat emboli. The CT attenuation valúes of pulmonary embolism should be carefully examined in the setting of acute trauma or after orthopedic procedures, as the rare but potentially fatal complicaron of FES may result. In trauma centers, multidetectorcomputed tomography is an essential tool to make the diagnosis of macroscopic fat embolism, and to exelude other causes of hypoxia, such as thrombotic pulmonary embolism. These reconstructions should be used for detailed evaluation of the pulmonary vasculature.
