Nodular pattern at lung computed tomography in fat embolism syndrome: a helpful finding.

The purpose of this study is to describe the computed tomography (CT) findings in pulmonary fat embolism syndrome (FES). The chest radiographs and CT scans of 5 patients with the diagnosis of FES as determined by the presence of at least 1 major and 4 minor criteria were reviewed. The radiologic features included ground-glass opacities, with different patterns of presentation seen in all patients. Three patients presented with alveolar opacities, and small (<1 cm) ill-defined nodules were seen in 4 of 5 patients. In the context of a patient with previous trauma and the clinical suspicion of FES, the presence of nodules at CT examination may be a helpful finding in the diagnosis of this entity. The chest radiographs and CT scans of 5 patients with the diagnosis of FES as determined by the presence of at least 1 major and 4 minor criteria as defined by Gurd and Wilson were reviewed.
