Abstract

OBJECTIVE: To report a new American family with hereditary diffuse leukoencephalopathy with spheroids (HDLS), including serial, presymptomatic and symptomatic, cranial MRIs from the proband. METHODS: We report clinical and genealogic investigations of an HDLS family, sequential brain MRIs of the proband, and autopsy slides of brain tissue from the probandĝ€™ s father. RESULTS: We identified seven affected family members (five deceased). The mean age at symptomatic disease onset was 35 years (range: 20ĝ€"57), and the mean disease duration was 16 years (range: 3ĝ€"46). Five affected individuals initially manifested memory disturbance and behavioral changes, whereas two experienced a mood disorder as their presenting symptom. Our probandĝ€™s father had been diagnosed clinically with vascular dementia, but his brain autopsy was consistent with HDLS. The proband had a cranial MRI prior to symptom onset, with two subsequent MRIs performed during follow-up. These serial images reveal a progressive, confluent, frontal-predominant leukoencephalopathy with symmetric cortical atrophy. CONCLUSIONS: The proband of our newly identified hereditary diffuse leukoencephalopathy with spheroids (HDLS) kindred had subtle evidence of an incipient leukoencephalopathy on a presymptomatic cranial MRI. Conceivably, MRI may facilitate identifying affected presymptomatic individuals within known HDLS kindreds, increasing the likelihood of isolating the causative genes.
