Abstract:
To analyze the clinical and image features for 12 patients of cerebral autosomal dominant arteriopathy with subcortical infarct and leucoencephalopathy (CADASIL).
Methods: A total of 12 CADASIL patients were collected in Xiangya Hospital of Central South University from January 2013 to December 2018. The clinical manifestation, risk factors, MRI imaging data and NOTCH3 mutations were analyzed retrospectively.
Results: The mean age of 12 patients was (47.25±9.49) years. The clinical manifestation was most common in cognitive impairment (75%) and stroke events (58.3%), and 2 cases showed cerebral hemorrhage. Migraine was only seen in 25% patients. All MRI showed white matter hyperintensity (WMH), lacune and enlarged perivascular space (PVS). WMH mainly occurred in the frontal parietal lobe (100%), temporal lobe (83.3%), external capsule (66.7%), occipital lobe (41.6%), callosum 41.6% and the temporal pole (33.3%), while lacune mainly appeared in frontal lobe (91.6%), parietal lobe(83.3%), temporal lobe(66.7%), basal ganglia (66.7%), brain stem (41.6%), occipital lobe (33.3%), cerebellum (8.3%). Enlarged PVS located in the basal ganglia (100%), partly under the cortex (45.4%). WMH of the patient with intracerebral hemorrhage was mild (Fezakas score 1-2), which was not found in external capsule. 16.7% of the patients had intracranial arterial stenosis. In 12 patients, 8 different Notch3 mutations were detected. The c1013G>c p.(Cys338Ser) located in exon 6, which was a new pathogenic mutation of CADASIL.
Conclusion: The patients with cerebral hemorrhage have mild WMH and specific genotype, indicating that the clinical characteristics of CADASIL with cerebral hemorrhage may be related to image features and genotype.
