A 22-year-old man with a previous uveitis episode was admitted to our hospital because of persistent hiccup. On admission, he presented right-upper quadrantanopia, mydriasis and lack of the light reflex in the left eye, left-sided hemiplegia, and bilateral pathologic hyperreflexia. The MR fluid attenuated inversion recovery images showed left side dominant,(More)
BACKGROUND Lymphomatosis cerebri (LC) is a rare subtype of primary central nervous system malignant lymphoma. The typical features of this disease exhibited on magnetic resonance imaging (MRI) without contrast enhancement are similar to those observed with diffuse leukoencephalopathy, mimicking white matter disorders such as encephalitis. Clinical features(More)
Abnormal plasticity has been reported in the brain of patients with Parkinson’s disease (PD), especially in the striatum. Although both l-Dopa and dopamine agonist remain to be the mainstay of the treatment in PD, their differential effects on cortical plasticity are unclear. We applied quadripulse stimulation (QPS) over the primary motor cortex (M1) in ten(More)
A 69-year-old woman complained of diplopia and truncal titubation after upper respiratory infection. She presented with mydriasis and external opthalmoplegia of bilateral eyes, ataxia, hyporeflexia and cervical-brachial muscle weakness. The protein abnormally increased (49 mg/dl) in the cerebrospinal fluid, and the serum anti-GQ1b and anti-GT1a IgG(More)
Two transferrin (Tf) glycan-isoforms were previously found in cerebrospinal fluid (CSF); one appears to be derived from serum (Tf-2) and the other from choroid plexus, a CSF-producing tissue (Tf-1). To analyse metabolic differences associated with the two isoforms, their ratio (Tf-2/Tf-1) was defined as the Tf index. Here we report that Tf indices of(More)
