Unilateral third nerve palsy caused by Guillain-Barré Syndrome.
BACKGROUND
Highly asymmetric clinical signs in a patient suggest the need for caution in making the diagnosis of Guillain-Barré Syndrome (GBS).


METHODS
Case report and literature review. We present a case of strictly unilateral left third cranial nerve palsy in a patient with GBS, review other highly asymmetrical cranial nerve palsies previously reported in this condition, and suggest an appropriate alternative differential diagnosis.


CONCLUSIONS
Unilateral third cranial nerve palsy is an exceptionally rare manifestation of GBS, expanding the spectrum of clinical signs and neuraxis involvement that may be seen in the condition.
