We present a patient with multifocal symptomatic osseous chordomas having unusual growth patterns with review of the pertinent literature. The patient was 62-year-old male and had multiple osseous chordomas located in sacral, thoracic, and paraclival jugular foramen areas. There was no metastasis in other organs. All affected sites were osseous. The(More)
OBJECT The clinical features of blood blister-like aneurysms (BBAs) that arise at nonbranching sites of the internal carotid artery (ICA) differ from those of saccular aneurysms. In this study, the authors attempt to describe optimal treatments for BBAs, which have yet to be clearly established. METHODS Ten of 483 patients with aneurysmal subarachnoid(More)
An experimental model was devised to elucidate the role of spinal blockade in posttraumatic syringomyelia. Thirty-eight Japanese White rabbits, each weighing about 3 kg, were used in this study. The animals were divided into four groups: in Group 1, eight animals received traumatic injury only; in Group 2, 12 animals received traumatic injury following(More)
The role of stenting in the treatment of patients with middle cerebral artery stenosis is not defined because of the high risk and difficulty in tracking. However, recent improvements in the technology, in particular of small, flexible stents and of small, flexible stents with accumulative stenting experience in occlusive intracranial disease endovascular(More)
BACKGROUND Early or ultra-early surgery for patients in poor neurological condition (Hunt and Hess grade IV or V) after ictus of aneurysmal subarachnoid hemorrhage is increasingly reported to prevent early rebleeding. To prevent any rebleeding after hospital admission, we have treated patients with poor-grade aneurysm during the same session as when(More)
Intramedullary spinal cord metastases are very rare. Patients with breast cancer as the primary source of intramedullary spinal cord metastases tend to do better than other types of cancer. We report the very unusual case of a woman with breast cancer who had two separate episodes of intramedullary spinal cord metastasis.
We report a case of a rare congenital teratoma that developed in a lipoma attached to a remnant human tail. A male newborn baby presented with a large, 3-cm mass with an open margin, which pedunculated from a tail attached to the midline skin of the coccygeal area. Magnetic resonance images demonstrated multiple sacral spinal bifida without cord tethering,(More)
OBJECTIVE To evaluate radiologic result of anterior cervical discectomy and fusion with allobone graft and plate augmentation, and the change of radiologic outcome between screw type and insertion angle. METHODS Retrospective review of clinical and radiological data of 29 patients. Segmental angle, height and screw angles were measured and followed. The(More)
OBJECTIVE This is retrospective study of clinical and radiological outcomes of anterior cervical fusion using Bongros-HA (BioAlpha, Seongnam, Korea) which is a type of synthetic hydroxyapatite (HA) spacer to evaluate the efficacy in its clinical application and usefulness as a reliable alternative to autograft bone. METHODS Twenty-nine patients were(More)
BACKGROUND Lateral mass plating is a safe fixating system for lower cervical fractures. Brain stem infarction after cervical lateral mass screw plating has not been reported in previous literature. We report a case of poor surgical technique leading to vertebral artery injury and brain stem infarction after cervical lateral mass plating. CASE DESCRIPTION(More)
