We analysed the clinical presentation, treatment and outcome of our own 36 cases of posterior circulation dissecting aneurysms (DA) and discussed the surgical indications and procedures regarding posterior fossa DA. Twenty one cases were male, 15 cases were female. Their mean age was 54±14 years. Clinical manifestations were subarachnoid haemorrhage (SAH)(More)
A 22-year-old woman presented with a very rare extradural en-plaque spinal meningioma manifesting as right hemiparesis and gait disturbance. Magnetic resonance imaging revealed a well-enhanced lesion extending from the C-1 to C-5 vertebral levels, compressing the cord dorsally. Computed tomography revealed a slightly enhanced mass with calcification in the(More)
The early appearance of high grade glioma on magnetic resonance (MR) imaging was retrospectively reviewed in the clinical records and MR images of 52 patients with intracerebral glioma treated in Osaka General Medical Center between 1997 and 2006. Three patients had no abnormal findings, and four patients had only hyperintense areas on T(2)-weighted imaging(More)
A 63-year-old, previously healthy man presented with a rare large intradural retroclival chordoma without bone involvement. Computed tomography showed that the tumor was completely intradural and did not involve the bone, as confirmed at intraoperative inspection. The tumor was totally excised via the anterior transpetrosal approach. Surgery is the most(More)
Two patients with non-small cell lung cancer presented with multiple brain metastases. They received gefitinib orally for the treatment of the primary lung lesions. About one month later, the brain metastases unexpectedly disappeared or became smaller. The patients survived without recurrence of brain metastases and growth of lung lesions for 3-4 years.(More)
Basilar trunk saccular aneurysms associated with fenestration are infrequent. Surgical treatment of a basilar trunk aneurysm is difficult because of its anatomic environment and complicated surgical exposure. We experienced two cases of basilar fenestration aneurysm, and the patients were treated using Guglielmi detachable coils. The usefulness of(More)
We present a case of traumatic pseudoaneurysm of the internal carotid artery (ICA) accompanied by skull base fracture, which was treated by endovascular trapping of the internal carotid artery. A 70-year-old woman met with a traffic accident and was admitted to our institution with epistaxis and accomapanied with shock. Angiography on day 2 showed(More)
