Cerebral Amyloid Angiopathy: Multiple neurolgic problems

Abstract

A 72-Year-old female with a history of migraine headaches presented with an acute onset of expressive aphasia, difficulty with memory and worsening of her headaches. An MRI of the brain was done which revealed diffuse white matter T2 hyperintensities (Figures 1). Due to worsening of the patient’s clinical symptoms a repeat MRI was performed four days later that revealed multiple micro-bleeds (Figure 2), as well as a lobar hemorrhage in left temporal lobe (Figure 2). An extensive workup including HIV testing, CSF examination for infectious etiology including protein 14-3-3 and demylineating disease was negative. Paraneoplastic and autoimmune workup was also non-diagnostic. A brain biopsy was performed due to the extensive white matter disease, which revealed Cerebral Amyloid Angiopathy (CAA) with focal granulomatous angiitis. The patient was treated with intravenous steroids with no significant improvement clinically. Two months after diagnosis, her disease course has remained static, without improvement or deterioration.
