Abstrakt: Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is a rare white matter degenerative disease manifesting as progressive cognitive decline, pyramidal, and extrapyramidal features resulting from mutations in the colony-stimulating factor-1 receptor (CSF1R) gene. We describe a sporadic case of a young man who developed five months history of progressive cognitive decline with predominant neuropsychiatric symptoms, suggestive of frontotemporal dementia. Brain magnetic resonance imaging (MRI) showed bilateral frontotemporal atrophy, high signal intensities in frontal and high parietal deep white matter with persistent diffusion restriction on follow-up imaging. Genetics showed a novel heterozygous mutation in CSF1R gene confirming the diagnosis of ALSP. Being a rare disease, and given its particular adult-onset presentation especially presenile cognitive impairment, it can pose a unique diagnostic challenge. The study highlights the importance of recognizing the disease early and broadens the clinical, genetic, and imaging spectrum of CSF1R gene mutation. [ABSTRACT FROM AUTHOR]
