Abstract
Purpose. To evaluate specific changes in MRI of the human brain, associated with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL).Materials and methods. We enrolled 24 patients with genetically confirmed CADASIL (19–81 y.o.). The following MRI sequences were performed for every subject: T1 MPR, T2, T2-FLAIR, DTI and SWI. Brain tissue lesions were assessed using STandards for ReportIng Vascular changes on nEuroimaging (STRIVE).Results. In the CADASIL group the following changes were observed (in % of patients): recent small subcortical infarcts – none; lacunes – 54%; white matter hyperintensities (WMH) by Fazekas 1 – 12%, Fazekas 2 – 17%, Fazekas 3 – 71% (sites of predilection: anterior temporal lobe and external capsule); cerebral microbleeds – 42%; enlarged perivascular spaces – 88%; brain atrophy – 27%.Conclusion. Neuroimaging signs of brain lesions are common for all types of cerebral small vessel disease, including CADASIL. However, there are some features in patients with CADASIL. The detection of petechial intraparenchymal hemorrhages is a diagnostically and prognostically useful marker, so it is very important to use gradient echo planar T2* or SWI sequence in the conventional MRI protocol.
