Meningiomas frequently invade cerebral venus sinuses, especially parasagittal meningioma to superior sagittal sinus. However, most invasions do not reach internal jugular vein. We present a case of parasagittal meningioma extending into the internal jugular vein through the sinuses. Radiological investigation revealed that the tumor was invading the sagittal, transverse, sigmoid sinus and junction of the internal jugular vein to subclavian vein, which was filled with tumor. The histopathological examinations revealed that both the cerebral tumor and mass in the internal jugular vein contributed to the transitional meningioma. This is a rare case of a meningioma extending into the internal jugular vein through the sinuses. According to this case, the frontal parasagittal meningioma could invade directly the internal jugular vein. The significance of this association to cerebral venus sinuses and internal jugular vein are discussed.

The authors analyzed 38 consecutive cases with an occipital arteriovenous malformation(AVM) in regard to visual field defect. The incidence of occipital AVM was 10.4% among 367 patients with a cerebral AVM treated between 1975 and 1994 in our institute Bleeding rate of occipital AVM in this series was 86.8%(33 casss) and it was significantly higher than that of AVM in other locations. Of 38 cases, 15 patients(39.5%) had a visual field defect on admission and all of them were accompanied by intracerebral hematomas caused by the rupture of AVMs. The presence o# visual field defect did not correlate with angioarchitecture in reference to pattern of nidus. feeding artery and draining vein. Of 15 patients with visual field defect, 10 patients showed homonymous hemianopsia and five patients. homonymous quadrantanopsia. The size and location of intracerebral hematoma correlated well with the type of visual field defect Among 38 patients. 2l patients underwent microsurgical resection(occipital interhemispheric approach: 11 parietooccipitai approach : 10) with six preoperative embolization and 1 postoperative gamma knife surgery Fifteen patients underwent gamma knife surgery with five preoperative embolization. One patient underwent embolization only. The results of treatment were as follows; There were no mortality and morbidity except for visual field defect We confirmed complete resection or obliteration o# malformed vessels in 25 patients and reduction of the nidus size in eight patients. Fivs patients were not followed After gamma knife surgery. two patients showed rebleeding during the follow up period Among f9 patients who had no visual field defect before treatment. three patients showed visual field defect after treatment(one after microsurgical resection using occipital interhemispheric approach. two after preoperative embolization. In 15 patients with visual field defect before treatment. four patients showed improvement in their visual field defect after treatment(three after microsurgical resection using occipital interhemispheric approach. one after gamma knife surgery). The paristooccipital approach did not change the status of visual field in any of the ten patients In occipital AVM. visual field defect was the most serious morbidity. Ruptured occipital AVM had a higher incidence of hemorrhage causing a visual field defect and had a higher indication of direct surgical approach than AVM of other location lu planning surgery of occipital AVM, one has to count microsurgical anatomy based on the visual pathway as well as clinical findings such as the angioarchitecture. location of intracerebral hematoma. and preoperative visual field

Moyamoya disease is a cerebrovascular disease of unknown etiology, which is characterized by bilateral stenosis or occlusion at terminal portion of internal carotid artery and at proximal portion of anterior cerebral artery and /or middle cerebral artery and abnormal vascular network in the vicinity of the arterial occlusions. It occurs frequently in Asian countries, particularly in Korea and Japan, but is rare in Western countries. To establish the etiology of moyamoya disease, much about the pathology from autopsies, factors involved in its pathogenesis, and its genetics have been studied. It may occur at any age from childhood to adulthood and in general, initial manifestation is cerebral ischemic symptoms in children and intracranial hemorrhage symptoms in adults. Because it progress and cause recurrent stroke, early diagnosis and proper management has been recognized. Cerebral angiography is essential for definitive diagnosis and treatment plan. Magnetic resonance imaging/magnetic resonance angiography is useful for diagnosis and follow-up tools after revascularization. Evaluation of the cerebral hemodynamics by single photon emission computed tomography and positron emission tomography is useful for diagnosis and assessment of the severity of cerebral ischemia in moyamoya patients. Surgical revascularization is effective for moyamoya disease manifesting as ischemic symptoms, to prevent further ischemia and infarction. In hemorrhagic type moyamoya disease, revascularization can be considered. Direct bypass, indirect synangiosis and combined methods are used. Outcomes of revascularization are excellent in preventing transient ischemic attacks in most patients.

A case of solitary plasmacytoma on the cervicothoracic junction is reported. Solitary palsmacytoma of the spine is uncommon and it may cause cord compression. The authors present the case of a 61-year old female patient with the symptoms of paraparesis and posterior neck pain. Spine MRI revealed cord compression from a bony mass at the level of C7-T2. After corpectomy and total mass removal, anterior interbody fusion with Ham's titanium mesh filled with allograft bone was performed, followed by radiotherapy. The patient has improved after operation and walks alone without assist. The solitary plasmacytoma of the spine is a lesion with the potential for long term remission or even cure in some cases. The above case was reported by the authors together with literature review.

Traumatic intracranial aneurysms are rare, compromising less than 1% of intracranial aneurysms. The case of 20-year-old man suffered from delayed frontal intracerebral hematoma, subarachnoid hemorrhage and intraventricular hemorrhage from traumatic pericallosal aneurysm 12 days after head injury is presented. Traumatic pericallosal artery aneurysm is always near the falcine edge, is unrelated to arterial branching point. Sudden movement of brain and artery causes vessel wall injury against the stationary edge of the falx. Because of high mortality rate of ruptured traumatic aneurysm, clinical suspicion must be focused on the prompt diagnostic work-up and early treatment.
Hydrothorax due to Migration of Ventriculoperitoneal Shunt Catheter
Kim, Hong-Ki,Seo, Eui-Kyo,Cho, Yong-Jae,Kim, Sang-Jin The Korean Neurosurgical Society 2008 Journal of Korean neurosurgical society Vol.43 No.3
A cerebrospinal fluid hydrothorax is a very rare complication following ventriculoperitoneal (VP) shunt and usually reported in children. We report a case of 47-year-old woman who developed massive hydrothorax and respiratory distress following intrathoracic migration of distal shunt catheter. After the confirmation of catheter in thoracic cavity using radionuclide shuntogram, the patient was successfully treated with laparoscopic shunt catheter reposition.
Large Ossified Rathke's Cleft Cyst -A Case Report and Review of the Literature-

We report a rare case of symptomatic Rathke's cleft cyst with thick calcified wall. Brain CT scans revealed a large cystic mass with round thick calcified wall. In this case, we selected the pterional approach instead of transsphenoidal approach due to the possibility of cystic craniopharyngioma. Histopathologically, it was calcified Rathke's cleft cyst with focal epithelial metaplasia. This case illustrates that calcification of the suprasellar cyst does not always suggest craniopharyngioma and the calcification pattern of Rathke's cleft cyst is different from that of the craniopharyngioma.
