Magnetic resonance imaging demonstrated a large posterior fossa cyst between the fourth ventricle and occipital meningocele, but the aqueduct was patent and there was no sign of(More)
To investigate the possible correlation between changes in monoaminergic neuronal activity and cerebral blood flow (CBF) in the same brain region after subarachnoid hemorrhage (SAH), monoamine levels were analyzed by both HPLC-ECD and fluorohistochemistry techniques, and CBF was measured by using colored microspheres. At the second day of SAH, significant(More)
A 48-year-old woman with a history of viral influenza infection was admitted with rapidly progressive numbness and weakness of the right extremities. On admission, general physical examination revealed no abnormality. Cerebrospinal fluid analysis showed no abnormal findings.

A 32-year-old man presented with a rapidly progressive decrease in visual acuity and diplopia. Magnetic resonance imaging (MRI) revealed a suprasellar cystic mass extending to the upper part of the clivus. The content of this cyst showed a slightly higher signal intensity than that of his cerebrospinal fluid (CSF) on T1-weighted images. The cyst stretched(More)
Chondroblastoma is a rare tumor which constitutes 1 % of the primary bone tumors . It most frequently arises from the epiphysis of the long bone. Involvement of the temporal bone is rare. Complete removal is a challenge due to anatomical complexity of the involved area including the middle ear and skull base. We encountered a case of temporal bone(More)
