Coil embolization for a ruptured posterior cerebral artery aneurysm with vertebrobasilar dolichoectasia.

A 74-year-old man suffered sudden loss of consciousness at home. Computed tomography revealed severe subarachnoid hemorrhage and an unusual posterior cerebral artery (PCA) aneurysm with vertebrobasilar dolichoectasia (VBD). The aneurysm was located in the right hypothalamus.

[Coil embolization of a ruptured posterior cerebral artery aneurysm via the internal carotid artery and a posterior communicating artery: a case report].

A posterior cerebral artery aneurysm is a rare condition. Various surgical approaches have to be considered for operating on these aneurysms because the position of the aneurysm and the surrounding structures restrict the operative field and render the operation difficult. Recently, endovascular treatments for posterior cerebral artery aneurysms have been reported to provide a good outcome.

Ruptured saccular aneurysm of a dolichoectatic internal carotid artery in a patient with agenesis of the contralateral internal carotid artery--case report.

A 42-year-old woman presented with very rare cases of ruptured saccular aneurysm of a dolichoectatic internal carotid artery (ICA) associated with agenesis of the contralateral ICA manifesting as sudden onset of severe headache and nausea without neurological deficits. Angiography and three-dimensional computed tomography demonstrated intraventricular hemorrhage with slight subarachnoid hemorrhage and dolichoectasia of the right ICA with agenesis of the contralateral ICA, as well as a saccular aneurysm of the ectatic right ICA. The aneurysm neck was clipped successfully.

Tumoral calcinosis in the upper cervical spine causing progressive radiculomyelopathy--case report.

A 54-year-old woman with chronic renal failure presented with tumoral calcinosis manifesting as progressive radiculomyelopathy. Magnetic resonance imaging revealed a spinal epidural mass in the C-2 to C-4 levels. The clinical and radiological findings suggested malignant tumor.

[A retrospective analysis of the outcomes of patients with aneurysmal subarachnoid hemorrhages: a focus on the prognostic factors].

The authors report a clinical analysis of the outcomes of aneurysmal subarachnoid hemorrhages in 112 patients. Cerebral angiography was conducted on 85 patients. Clipping or wrapping of the aneurysm was performed on 81 patients.

[A case of clival chordoma without bone destruction].

A case of clival chordoma without bone destruction is reported. A 28-year-old man was admitted to Kagoshima University Hospital on April 8, 1983 with the complaints of headache, displopia and gait disturbance. Neurological examination revealed the right eighth, ninth, tenth nerve palsy and gait disturbance.

Giant mucocele of paranasal sinuses.

A large mucocele of the frontal and ethmoidal sinuses with extracranial, intracranial, and intraorbital extension accompanied by total destruction of the left frontal sinus was treated successfully. We chose a two-stage surgical procedure for radical removal of the lesion. It is important to ascertain the degree of dural involvement, not only because extensive involvement of the dura mater presents technical surgical difficulties, but also because this knowledge provides clues regarding the pathology of the lesion.
