The objective of our study is to determine and compare the diagnostic utility of the conventional MRI and DTI in differentiating cerebral fat embolism syndrome from diffuse axonal injury. If the patient develops pulmonary symptoms, a chest x-ray should be obtained as a screening tool. This dramatically increases the morbidity and mortality rate of the patient. The fat embolism syndrome is a well-known complication in trauma patients. MRI sequences of the chest area included T2- and T1-weighted fast spin-echo imaging, T2*-weighted imaging, T1-weighted 3-dimensional gradient-echo imaging with or without a fat-suppression pulse, short tau inversion recovery, and in-phase/opposed-phase imaging. FES has no specific treatment and requires supportive care, although it can be prevented by early fixation of bone fractures. Its diagnosis is based on medical history and supportive imaging data and is usually not difficult. Fat embolism syndrome with cerebral fat embolism, rarely observed at our neurology department, is often associated with long bone fractures. Sakashita M, Sakashita S, Sakata A, et al.
