Pulmonary fat embolism probably occurs commonly after major orthopedic injuries and after orthopedic surgery. Furthermore, tiny fat emboli can often be shown by transesophageal echocardiography during orthopedic surgery. However, large macroscopic are rarely identified radiologically. Macroscopic fat emboli have been previously described in the common femoral vein and inferior vena cava on abdominal imaging. To the authors' knowledge, a macroscopic fat embolus in the pulmonary arteries has not been previously described. The authors report a case of a woman who, on computed tomography, had a large fat embolus after intramedullary rod placement for an isolated left femur fracture.
脂肪栓塞常见于严重骨科损伤后及骨科手术后。此外，在骨科手术期间，经食管超声心动图常可显示微小脂肪栓子。然而，影像学很少能发现肉眼可见的大脂肪栓子。肉眼可见的脂肪栓子先前已在腹部影像检查中发现存在于股总静脉和下腔静脉。据作者所知，肺动脉内肉眼可见的脂肪栓子此前尚无报道。作者报告一例女性患者，在因单纯左股骨骨折行髓内钉置入术后，计算机断层扫描显示有一个大的脂肪栓子。
