Eight members were diagnosed with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, and disease diagnoses corresponded with autosomal incomplete dominance inheritance. The primary clinical manifestations included paralysis, dysarthria, and mild cognitive deficits. Magnetic resonance imaging revealed diffuse leukoencephalopathy with involvement of bilateral anterior temporal lobes, in particular the pons. In addition, multiple cerebral infarction was identified in the proband. Sural nerve biopsy findings of the proband revealed granular osmophilic material deposits in the extracellular matrix, which were adjacent to smooth muscle cells of dermal arterioles. Screening exons 2-4 for NOTCH 3 mutations by direct sequencing did not reveal any abnormalities.展开更多

We performed enhanced depth imaging optical coherence tomography （EDI-OCT） to evaluate the retinal vessel changes in CADASIL patients and assessed their consonance with brain magnetic resonance imaging （MPRI） findings. Methods： Of 27 genetically confirmed patients and an equal number of controls were recruited at the Peking University First ttospital from January 2015 to August 2016. All patients underwent 7T-MRI of the brain. Fazekas score, number of small infarcts and microblecds were evaluated. All patients and controls underwent EDI-OCT to measure subtbveal choroidal thickness （SFCT）, inner and outer diameters as well as arterial and venous wall thickness, and arterial venous ratio of the inner （AVRin） and outer diameters （AVRout）. The relation between retinal vessel changes and Fazekas scores, numbers of small infarcts, or microbleeds was analyzed. Paired t-test was used to compare the SFCT and retinal vessel measurement data between patients and controls. Spearman＇s correlation was used to investigmc the correlation between retinal vessel changes and MRI lesions. Results： In CADASI L patients, mean SFCT （268.37 ± 46.50 μm） and mean arterial inner diameter （93.46 ± 9.70 gin） were signilicantly lower than that in controls （P 〈 0.00 ）, P = 0.048, respectively）. Mean arterial outer diameter （ 131.74 ± 10.87 μm）, venous inner （ 128.99 ± 13.62 μm） and outer diameter （ 164.82 ±14.77 μm）, and mean arterial （ 19.13 ±1.85 μm） and venous （ 17.91 ±2.76 μm） wall thickness were significantly higher than that in controls （P = 0.023, P 0.004, P 〈 0.001, P 〈 0.001, respectively）. Arterial inner diameter （r= - 0.39, P 0.044）] AVRin （r -0.65, P 〈 0.001）, and AVR,, （r =0.56, P - 0.002） showed a negative correlation with the number of small infarcts. Venous inner diameter （rs=0.46, P= 0.016） showed a positive correlation with the number of small infarcts. Venous inner diameter （r 0.59, P = 0.002）, outer diameter （rs=0.47, P= 0.017）, showed a positive correlation with the number of cerebral microbleeds （CM Bs）. AVRin （r =0.52, P = 0.007） and AVRout （r = -0.40, P =0.048） showed a negative correlation with the number of CMBs. Conclusions： Measurement of retinal vessels using EDI-OCT correlates moderately well with MRI parameters. EDI-OCT might bc a useful evaluation tool for CADASIL patients.展开更多

It is not infrequent for CADASIL to be mistaken and mistreated for multiple sclerosis (MS). A much less frequent but existing scenario is the co-occurrence of CADASIL and MS (or MS-like inflammatory condition). Such patients may present with spinal cord lesions, brain or spinal cord enhancing lesions, positive oligoclonal bands and high IgG index in the cerebrospinal fluid and good response to corticosteroids or immunomodulating treatments. CADASIL through various mechanisms may trigger or modulate autoimmune reactions, and either be complicated by an inflammatory component or cause an MS-like disorder.展开更多
