We report a rare case of a ruptured dissecting anterior inferior cerebellar artery (AICA) aneurysm treated by endosaccular embolization with a Guglielmi detachable coil (GDC). An 85-year-old female presented with headache. Computed tomographic (CT) scan showed subarachnoid hemorrhage and intraventricular hemorrhage in the fourth ventricule. Cerebral(More)
Intrasacral fixation technique devised by Jackson is said to provide rigid lumbosacral fixation. We treated 3 cases of lumbosacral lesions using this technique in which lumbosacral segment had become extremely unstable during surgical intervention adding to the effect of original lesions. In all cases, surgeries were performed in 2 stages, intrasacral(More)
A 57-year-old female presented with a left petroclival meningioma fed by the meningohypophyseal trunk of the internal carotid artery (ICA). The enlarged tentorial marginal artery and inferior hypophyseal artery were successfully embolized with the TruFill DCS Detachable Coil System through a 0.019-inch inner diameter microcatheter. Superselective(More)
A very rare case involving an endodermal cyst of the cervical spinal canal was documented. In 1999, a 28-year-old male presented with mild tetraplegia due to a traffic accident and consequently, he was admitted to another hospital. Magnetic resonance imaging (MRI) performed at that time demonstrated a cervical cord cyst. He was treated conservatively and as(More)
The authors reviewed their clinical experience with preoperative embolization of metastatic spinal tumors. Between October 2000 and September 2003, 20 patients (13 men and 7 women; average age 68.3 years, range 44-82 years) underwent 24 spinal operations for 22 spinal metastatic tumors. Nineteen spinal operations (79%) were planned preoperative embolization(More)
A 53-year-old man presented with malignant lymphoma manifesting as disturbances of walking and standing. Magnetic resonance (MR) imaging showed multifocal bifrontal lesions which were enhanced by gadolinium-diethylenetriaminepenta-acetic acid. Positron emission tomography (PET) with [18F]fluorodeoxyglucose showed high uptake of tracer in the lesion. The(More)
