[Juvenile arteriosclerotic leukoencephalopathy: anatomoclinical study of a case].
A 34-year old right-handed man was suffering from recurrent cerebro-vascular insults. CT-scans revealed several subcortical lacunar infarcts, and leukoaraïosis. Arteriography of the left and the right carotid arteries was performed respectively on the 4th and the 9th year of the disease, and did not elicit significant extracranial and intracranial vascular lesions. There were no arguments in favor of infectious, inflammatory, or auto-immune vascular diseases. The patient had tardive hypertension and dementia, and died at the age of 44. Pathological findings, limited to the brain and cervical spinal cord, revealed numerous ischemic lacunar infarcts. Histological lesions were consistent with the diagnosis of arteriosclerotic leukoencephalopathy. There were oedema, palor, and loss of myelin in the white matter, and nonspecific diffuse arteriosclerotic lesions that were particularly pronounced in the intimal part of the arterial wall. No inflammatory process nor amyloid deposits were found. Despite the onset of the disease in a young adult and the late occurrence of hypertension, our case report shares most of the pathological features of the Binswanger's type of arteriosclerotic encephalopathy.
