Post-traumatic severe fat embolism syndrome with uncommon CT findings

Although the diagnosis of fat embolism syndrome is usually based on clinical findings, we describe ill-defined centrilobular and subpleural nodules in addition to ground-glass opacities and consolidation on a computed tomography scan of the chest in a trauma patient with fat embolism syndrome. The nodules presumably represent alveolar oedema, microhaemorrhage and an inflammatory response secondary to ischaemia and cytotoxic emboli in fat embolism syndrome. The literature of computed tomography findings in patients with fat embolism syndrome is reviewed and summarized.
