A 70-year-old man presented to the clinic with impairment of visual memory and marked predominantly right sided mesial temporal lobe atrophy on imaging. He died 6 years following symptom onset and neuropathological examination showed concomitant progressive supranuclear palsy and Lewy body pathology. Although he did not fulfil clinical criteria for either condition at presentation, we propose that interactions between the two pathologies in mesial temporal regions could result in this atypical clinical phenotype.
- dementia with Lewy bodies
- progressive supranuclear palsy
