A 60-year-old, right-handed man suffered from mild word finding difficulties and kanji agraphia. Brain computed tomography revealed left temporal lobe hemorrhage, and cerebral angiogram revealed multiple durai arteriovenous fistulas (d-AVFs) in the left anterior cranial fossa and middle cranial fossa. Surgical shunt ablation was performed, and the lesions were obliterated completely. Analysis of the kanji agraphia during neuropsychological rehabilitation showed similar symptoms to those of the left posterior inferior temporal lobe lesion. Re-evaluation of magnetic resonance imaging showed multiple microbleeds on the left inferior temporal lobe, which could be responsible for the kanji agraphia. In this case, analysis of clinical symptoms with careful neuropsychological examination was important for understanding these pathologies.
