A case of nontraumatic chronic subdural hematoma due to obstruction of dural vessels by tumor cells is presented and 25 reported cases are reviewed. A 39-year-old female was referred for headache, vomiting, disturbance of consciousness and right homonymous hemianopia with macular sparing. She had undergone mammectomy for medullary nodular carcinoma of the(More)
Infectious disease is a common complication of mild hypothermia therapy. However, very little has been reported about immune response during hypothermia. In the present study, the number and subset of peripheral lymphocytes and mitogen response to phytohaemagglutinin (PHA) and concanavalin A (Con-A) were examined in 14 patients who received mild hypothermia(More)
BACKGROUND Ankylosing spondylitis (AS) is rarer in Japan than in Europe, probably because the European criteria, not well known by Japanese general physicians, regard AS as a progressive stage of axial spondyloarthritis (SpA). HLA-B27 is an important diagnostic marker of SpA; however, the incidence of the HLA-B27 allele is as low as 0.4 % in Japan. For(More)
A 62-year-old right-handed woman had presented progressive speech impediment over 4 months. She was alert without any convulsions or involuntary movements. Neurological examination showed Wernicke's aphasia, constructional apraxia. Her magnetic resonance imaging (MRI) showed an old cerebral infarction in the left parieto-occipital area, in addition to(More)
A 46-year-old female presented with an intracranial hypoglossal neurinoma manifesting only as spasticity in the lower extremities without hypoglossal nerve paresis. Magnetic resonance imaging greatly aided in the early detection of the tumor with this atypical presentation. Unilateral suboccipital craniotomy with resection of the occipital condyle allowed(More)
A 46-year-old male presented with acute visual loss in the right eye, high fever, nausea, and vomiting. This was caused by herniation of the third ventricle into empty sella at 15 months of surgery for pituitary apoplexy. The sellar-suprasellar tumor was totally removed via a transcranial approach. Histological examination showed chromophobe adenoma with(More)
Cerebellar hemangioblastomas are known to be occasionally associated with abdominal tumors such as renal cyst and renal cell carcinoma. But most of the abdominal tumors reported are clinically silent and usually diagnosed after the hemangioblastomas have been found in the central nervous system. We report a rare case in which a renal cell carcinoma(More)
