Atypical presentation of fat embolism syndrome after gunshot wound to the foot.
A 42-year-old man sustained a gunshot wound to the foot, which caused multiple fractures of the tarsal bones. Over the course of 6 hours, he became obtunded and began to experience respiratory compromise and neurologic symptoms. On magnetic resonance imaging, he was found to have innumerable tiny infarcts consistent with fat embolism syndrome. He was placed in a spanning external fixator. The patient remained in a coma for 6 weeks after injury but gradually regained function. Fat embolism syndrome is classically described as resulting from injury to the diaphysis of a long bone, but it can occur secondary to trauma of the foot. Neurovascular status must be continually evaluated in the setting of any bony trauma, and index of suspicion should remain high when neurologic deficits are encountered.
