Clinical presentation of Moyamoya angiopathy in Europeans: experiences from Germany with 200 patients.
Journal of Neurology 2019 June
INTRODUCTION: Moyamoya angiopathy (MMA) is a rare vasopathy, especially among European Caucasians. Data about demographics, clinical presentation, comorbid conditions, radiological findings as well as laboratory and cerebral spinal fluid (CSF) data are sparse.
METHODS: Patients with MMA treated in the Alfried Krupp Hospital, Essen, Germany, between 2010 and 2017 with focus on demographic, clinical, radiological and laboratory as well as CSF data were evaluated retrospectively. Patients with non-Caucasian family background were excluded from this study.
RESULTS: Altogether 200 European Caucasian patients with MMA were identified. There was a female predominance of 3.2:1. The mean age at first presentation was 32.9 years and the mean age of diagnosis was 36.0 years. Eleven of 194 index patients (5.7%) showed a familial presentation. In 11.6% posterior cerebral artery was additionally involved, in 4% additionally cerebral aneurysm and in 2.5% dysgenesis of corpus callosum was found. Most patients suffered from transient ischemic attacks (71.5%) and stroke (82%). Cerebral hemorrhage was found in 9.5%. Livedo racemosa was an associated symptom in 12.8% of patients and thyroid diseases were found in 23.8%.
CONCLUSIONS: Compared with Asian data, cerebral hemorrhages are infrequent and female predominance is accentuated among European Caucasians. Some former unknown rare features like associated livedo racemosa, dysgenesis of corpus callosum and associated syncope have been discovered systematically for the first time in this huge European Caucasian cohort.
