Guillain-Barré syndrome and glioblastoma.

Guillain-Barré syndrome (GBS) is defined as an acute demyelinating peripheral neuropathy. We describe a case of GBS in a patient with glioblastoma undergoing chemotherapy treatment. A 57 year old woman diagnosed with glioblastoma developed a subacute progressive history of bilateral symmetric numbness of her fingers and toes, belt-type neuropathic pain, a left facial droop and upper and lower extremity muscle weakness.
