Asymmetrical weakness associated with central nervous system involvement in a patient with guillain-barrè syndrome.

Guillain-Barrè syndrome (GBS) is usually associated with symmetrical weakness, and therefore asymmetrical weakness may confuse diagnosis. We report on a patient with GBS subsequent to Campylobacter jejuni enteritis who had asymmetrical weakness with CNS involvement. The patient tested positive for anti-ganglioside antibodies, including anti-GM1 IgM, anti-GD1b IgG, and anti-GT1a IgG. Patients with GBS can manifest asymmetrical signs and symptoms attributable to CNS involvement. Prompt, accurate diagnosis and treatment of post-C. jejuni GBS is especially important because its prognosis is relatively poor.
