The acute motor axonal neuropathy variant of Guillain-Barré Syndrome diagnosed after ankle trauma.

A case of Guillain-Barré syndrome (GBS) was diagnosed in a patient admitted to the emergency department (ED) after ankle trauma was presented. GBS is generally defined as immune-mediated peripheral neuropathy that develops after an infection. Our patient presented to ED with ankle trauma that developed after fatigue. Lateral, medial, and posterior malleolar fractures were detected in the ankle. The patient with loss of motor strength in the distal muscles was diagnosed with acute motor axonal neuropathy variant of GBS. After GBS treatment, the patient's loss of muscle strength regressed, and then surgical treatment was performed. We aimed to present this case report, which emphasizes the systematic approach of the emergency physician without having a large differential diagnosis list.
