A 25-year-old female developed fever after a cold 2 weeks post-cesarean delivery. 20 days later, she experienced mid-chest numbness with a band-like sensation, complete sensory loss below the band, lower limb weakness, and urinary incontinence. If the patient also presents with bilateral peripheral facial palsy, decreased limb muscle strength, absent tendon reflexes, and cerebrospinal fluid (CSF) showing albuminocytologic dissociation, which disease should be considered?
