Abstract
Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia, and Nasu Hakola disease or polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy are both underrecognized progressive degenerative white matter diseases that can present with young dementia, leukoencephalopathy and brain calcifications. We report and compare three cases in terms of clinical phenotype, imaging and neuropathological findings. Both cases have led to the identification of two novel causal mutations.

Sequencing of the CSF1R gene in the first case was performed by the group of Rosa Rademakers (Mayoclinic, USA). Sequencing of the TREM2 gene in our cases was performed by the lab of Leena 19 Peltonen (Department of Molecular Medicine, National Public Health Institute, Biomedicum, Helsinki, Finland).
