Introduction
Hereditary diffuse leukoencephalopathy with spheroids (HDLS) is an adult onset leukodystrophy, causally related to mutations in the colony-stimulating factor 1 receptor (CSF1R) gene. We report the unique case of a Greek HDLS patient, demonstrating an unusual phenotype, reminiscent of primary progressive aphasia (PPA).
Methods
A 63-year-old woman was referred with a 2-year history of deteriorating language and memory deficits, apathy, and two generalized tonic-clonic seizures. Neurological and neuropsychological examination revealed prominent aphasia with a pattern consistent with nonfluent variant of PPA. However, brain MRI disclosed confluent T2 and FLAIR white matter hyperintensities with frontal emphasis, whereas genetic testing corroborated the diagnosis of HDLS.
Discussion
PPA-like patterns may rarely develop in the context of HDLS. Prompt diagnosis of this leukoencephalopathy is essential, since preliminary data suggest that it could represent a potentially treatable disorder.
