Central post-stroke pain (CPSP) including thalamic pain is one of the most troublesome sequelae that can occur after a cerebrovascular accident. Although the prevalence of CPSP among stroke patients is relatively low, the persistent, often treatment-refractory, painful sensations can be a major problem and decrease the affected patient's quality of life.

Two patients presented with metastatic pineal tumors. A 69-year-old man had gait disturbance, dementia, and urinary incontinence but no history of previous malignancy. Magnetic resonance imaging of the brain revealed a 23-mm tumor in the pineal region and obstructive hydrocephalus. A 37-year-old man had been treated for thyroid cancer. He presented with(More)
Bevacizumab (BEV), an inhibitor of vascular endothelial growth factor A, has been used for primary and recurrent malignant gliomas in Japan since June, 2013. Previous randomized controlled studies demonstrated that BEV prolonged the progression-free survival, but not the overall survival (OS) of patients with newly diagnosed glioblastoma. The aim of the(More)
BACKGROUND Primary pineal malignant melanomas are uncommon intracranial tumor. Here we discuss and review a case of primary pineal malignant melanoma over its feature of imaging studies, pathological findings, and management. CASE DESCRIPTION A 49-year-old woman receiving renal dialysis underwent computed tomography due to a 4-month history of tinnitus(More)
This 48-year-old-man who had undergone right thyroid lobectomy for undifferentiated thyroid carcinoma nine years earlier developed generalized seizures. His cerebrospinal fluid was xanthochromic with elevation of total protein. Computed tomography (CT) showed mixed-density bilateral ventricular masses. Magnetic resonance imaging (MRI) revealed multiple(More)
Given the anatomical proximity of tuberculum sellae meningioma (TSM) to the hypothalamo-pituitary system, pituitary function impairments are of great concern. We retrospectively investigated pituitary function changes following surgery in patients with TSM using pituitary provocation tests (PPTs). Thirty-one patients (27 females and 4 males) with TSM(More)
A 71-year-old woman presented with a 2-month history of progressive exophthalmos. Magnetic resonance imaging revealed a tumor occupying the right frontal sinus that compressed the right orbit and eye ball. The tumor was resected through a right frontal craniotomy. The pathologic diagnosis was leiomyoma and similar to the histologic diagnosis of a uterine(More)
We report rapid malignant transformation of diffuse astrocytoma to glioblastoma during pregnancy in a young woman. A 21-year-old woman was found to have a non-enhancing right frontal lesion, supposed to be a low-grade astrocytoma according to magnetic resonance imaging (MRI) studied for chronic headache. Due to the absence of clinical symptoms, the patient(More)
