A 39-year-old woman developed right hemiparesis in a few days. Magnetic resonance images revealed cerebral infarction in the territory of the left lenticulostriate artery, and MR angiography showed severe stenosis of the middle and anterior cerebral arteries and moderate one of the vertebral arteries. Bilateral and symmetric T1 hyperintensity in the pulvinar (T1-weighted imaging-pulvinar sign; "T1 pulvinar sign") was detected, which is recognized as a key imaging of Fabry disease. The α-galactosidase A gene analysis, however, showed no mutation. Although specific physical symptoms were solely short stature and oligomenorrhea, the diagnosis of Turner syndrome was confirmed by the chromosome analysis which showed mosaicism of 45XO and 46X,r(X) (60%:40%). To our knowledge, this is the first report of Turner syndrome with "T1 pulvinar sign".
