RESUMO
We report a man who exhibited pure agraphia after suffering a left subcortical infarction involving part of the thalamus and the basal ganglia. His writing difficulty was characterized by stopping, letter omission, and substitution in spontaneous writing and writing to dictation, but he was able to copy normally. Decreased perfusion in the left frontal lobe and temporal cortex was noted on brain single-photon-emission computed tomography . This patient's agraphia persisted at follow-up 52 days later. We suggest that the subcortical lesion in this patient caused pure agraphia secondary to diaschisis of the interconnected cortical area.

Among various etiologies of bilateral vestibulopathy, meningitis has rarely been reported and no case by varicella- zoster meningitis. We experienced a case of bilateral vestibulopathy and aseptic meningitis developed in a 22-year old woman who was previously affected by chicken pox. She had oscillopsia and unsteadiness of gait when the typical skin lesion of chicken pox was improving. Neurootologic examination, bithermal caloric irrigation, and rotary chair test showed the result compatible with complete bilateral vestibulopathy. With mild headache and nausea, her CSF finding revealed aseptic meningitis and the serum antibody for varicella-zoster virus (VZV) was elevated. On the contrary of previous report that associated with bilateral vestibulopathy tend to poorly improved, this patient showed a favorable outcome with recovery of symptoms and caloric test.
