A 58-year-old man presented with an extremely rare case of "pure type" spinal tanycytic ependymoma associated with hematomyelia manifesting as sensory disturbance of the bilateral hands and weakness of the right arm. Magnetic resonance imaging demonstrated a tumor in the spinal cord from C-2 to C-4 levels. The soft gelatinous tumor was subtotally resected(More)
OBJECT It remains unclear whether elderly patients with compressive cervical myelopathy can be expected to experience a promising surgery-related outcome after undergoing expansive laminoplasty. The purposes of this study were to evaluate the efficacy of expansive laminoplasty in elderly patients with cervical myelopathy due to multisegmental spondylotic(More)
Intracranial epithelioid hemangioendothelioma (E-HE) is an extremely rare, vasoformative tumor with variable biological behavior. A huge E-HE confined to the upper side of the tentorium has not been documented previously. Recognizing E-HE as a specific vascular tumor is important, and complete tumor removal guarantees long-term survival. Here, we report an(More)
A chordoid glioma in the third ventricle was studied immunohistochemically and ultrastructurally. In this report, special attention is paid to the histogenesis in relation to the pathological appearance and unique anatomic location of this tumor. Light microscopic and immunohistochemical findings were similar to those reported previously. Ultrastructurally,(More)
Vascular endothelial growth factor (VEGF) is a key mediator of tumor angiogenesis. Interferons (IFNs) have been widely used in the treatment of malignant or recurrent gliomas with only marginal benefit. The association between IFNs and VEGF expression remains unclear and should be an intensively investigated subject. The present study therefore examined the(More)
Chordoma is a rare cartilaginous tumor, for which bleeding presentation is unusual. We report a case of rare hemorrhaged clival chordoma, which was diagnosed correctly by magnetic resonance imaging. A 32-year-old man presented with nasal bleeding. The tumor was totally removed via a trans-sphenoidal approach, from which the surgical specimen confirmed(More)
We report a case of bacterial aneurysm complicated by severe infectious endocarditis. A 34-year-old man developed idiopathic fever and general fatigue persisting for a month. He was admitted to our institution, and examinations revealed severe bacterial endocarditis with vegetation at the mitral valve and mitral incompetence. Right after admission, he(More)
