Pulmonary Fat Embolism Syndrome:X-ray and CT Imaging Characteristics

Objective:To investigate radiographic and computed tomography features of pulmonary fat embolism syndrome(FES).Method:A retrospective review was performed on the data of 8 cases FES proved by clinical diagnosis.The chest radiographs and CT studies were assessed by two radiologists.Results:On chest radiographs,bilateral diffuse distributed pulmonary shadows were seen in 5 cases,a middle or lower predominance in 2 cases.Increased pulmonary markings were seen in 1 case.On CT scans,5 cases showed ground-glass opacities,which had a diffuse distribution in 3 cases,patchy distribution resulting in a geographic appearance in 1 cases,the other one with intralobular septal thickening.Multi-focal areas of consolidation or nodules were seen in 2 patients.Bilateral pleural effusion was seen in 2 patients.Conclusion:Radiography is still the reliable modality in diagnosing FSE and MSCT can provide much more characteristic information.
