Unexpected rapid improvement and neurogenic stunned myocardium in a patient with acute motor axonal neuropathy: A case report and literature review
Recovery of Function
Acute Motor Axonal Neuropathy-type Guillain-Barré Syndrome (GBS) is a subset of GBS with either a rapidly improving or protracted course that was first described in China. We describe a 27-year-old previously healthy woman with weakness that progressed to complete tetraplegia and areflexia within 2 weeks after an upper respiratory illness. A lumbar puncture performed 4 days after onset of neurologic symptoms was inconclusive for GBS, and electromyography revealed complete motor axonal neuropathy. The patient had Mycoplasma pneumoniae in her nares and blood, and several antiganglioside antibodies in her blood. She was treated with plasmapheresis, antibiotics, and physical therapy. Her motor function and reflexes improved rapidly with treatment, and she was able to ambulate within 3 weeks. She also experienced cardiomyopathy, which improved with plasmapheresis. We report a rare case of Mycoplasma pneumonia-associated acute motor axonal neuropathy-type GBS presenting with complete tetraplegia, areflexia, and neurogenic stunned myocardium that rapidly improved with plasmapheresis.
