Abstract

A 67 year old patient developed progressive behavioral abnormalities and executive dysfunction corresponding to the diagnosis of behavioral variant of frontotemporal dementia (bvFTD). Unexpectedly, MRI showed multiple vascular ischemic and hemorrhagic lesions as typically found in sporadic cerebral amyloid angiopathy (SCAA). Based on clinical, laboratory and imaging findings the diagnosis of possible SCAA was made. SCAA may represent another important differential diagnosis among the various underlying disease pathologies of the bvFTD syndrome.
