A 17-year-old Pakistani female patient presented with acute onset flaccid quadriparesis with nerve conduction studies showing demyelinating polyneuropathy consistent with Guillain-Barre’ syndrome. She was treated with 4 plasmapheresis sessions. She developed raised blood pressure, headache, visual loss and generalised seizures on the 13th day of admission. MRI of the brain on contrast showed findings of altered signals low on T1-weighted image, high on T2-weighted image and fluid-attenuated inversion recovery in the white matter of bilateral occipital, parietal and right frontal lobe consistent with posterior reversible encephalopathy syndrome. The patient was administered antiepileptic and antihypertensive drugs to control seizures and blood pressure. She was discharged in a stable state. On follow-up her visual loss had recovered completely and she had regained full motor strength in all four extremities after 6 weeks. Fresh MRI of the brain revealed complete resolution of lesions. Antihypertensive and antiepileptic medication was discontinued. She is independent in all her daily activities.
