CSF1R-related leukoencephalopathy is an autosomal dominant neurological disorder causing microglial dysfunction with a wide range of neurologic complications, including motor dysfunction, dementia and seizures. This case report highlights an unusual presentation of CSF1R -related leukoencephalopathy with radiographic spinal cord involvement initially diagnosed as multiple sclerosis. The case highlights the importance of considering adult-onset neurogenetic disorders in the setting of white matter disease. Genetic testing provides a confirmatory diagnosis for an expanding number of adult-onset leukoencephalopathies and informs therapeutic decision-making.
