| Abstract |
|
Cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited
microangiopathy caused by mutations in the Notch3 gene. Typical findings from magnetic resonance imaging (MRI) include
multiple subcortical lacunes, extensive white matter change and multiple cerebral microbleeds (CMBs). Whereas MRI findings are
well described in Caucasian patients with CADASIL. There is a paucity of data on Asian patients. We aim to characterized
imaging findings in Asian patients with CADASIL. The study population comprised 73 patients who underwent brain MRI between
March 2012 and May 2013. T1-weighted image, susceptibility weighted image (SWI), and fluid attenuated inversion recovery
(FLAIR) images were analyzed by visual inspection. Clinical information at time of imaging was available for all patients. The
mean age of patients (44 men, 29 women) was 63.2±11.8 (SD). In patients with CADASIL, lacunes (76.7%, 56 of 73), CMBs
(74%, 54 of 73), and area of white mater hyperintensities (98.6%, 72 of 73) were observed. Lacunes, CMBs, and WMHs were
located predominantly in the cortical-subcortical lesion (57.5%, 54.8%, and 98.6%, respectively). These findings suggest that
cortical-subcortical area is the most frequently injured area of brain in CADASIL. Further studies are needed to validate our
findings. |
