  • Objectives : The best results of treating intracranial aneurysms can be achieved with treating aneurysm before they rupture. Some recent reports about the risk of the bleeding of the unruptured intracranial aneurysm(UIA) being too low(0.05% per year) compared with 1~2% of the previously reported bleeding probability, casts the question about the need for treatment of the UIAs. The purpose of this report is to review the recent reports about the risk of rupture of the UIAs and to assess the morbidity and mortality associated with surgical treatment for UIAs.

  • A case of intradural extramedullary cavernous angioma is presented with headache, dizziness, and bilateral sensorineural hearing loss caused by an intracranial superficial hemosiderosis. It was incidentally found in a patient with a 3-month history of sustained headache, dizziness and a 3-year history of hearing difficulty. The neurological examination was unremarkable in the lower extremity. MR images showed an intracranial superficial hemosiderosis mostly in the cerebellar region. Myelography and MR images of the thoracolumbar spine revealed an intradural extramedullary mass, which was pathologically proven to be a cavernous angioma. T12 total laminoplastic laminotomy and total tumor removal were performed without any neurologic deficits. The patient's symptoms, including headache and dizziness, have been absent for three years. Intradural extramedullary cavernous angioma can present with an intracranial superficial hemosiderosis as a result of chronic subarachnoid hemorrhage.

  • The authors report a case of recurrent subarachnoid hemorrhage (SAH) after complete occlusion of an intracranial aneurysm. It is known that regrowth of an aneurysm after the complete clipping is a rare event. For detection of recurrence, however, it may be necessary to follow up with the patient regularly after the initial operation for intracranial aneurysms, because re-rupture of an aneurysm can cause a fatal result, and the cumulative risk of a recurrent SAH is thought to be not low over time.

  • The transcranial Doppler(TCD) is a technique for measuring blood flow velocity of intracranial and extarcranial arteries. This examination based on Doppler effect which was first formulated in 1842 by the Austrian physicist Christian Doppler. In 1982, Rune Aaslid first maked 2MHz pulsed probe and recording intracranial vessels with transcranially. There are six criteria utilized in gaining positive identification of the intracranial vessels. The six criteria are as follows l)acoustical windows 2)depth of sample volume 3)direction of flow 4)spatial relationship of ACA and MCA bifurcation 5)mean velocity and 6)response common carotid artery compression and/or oscillation test. The affected factors for TCD examination are angle of insonation, posture of subject, age, gender, hematocrit, metabolic factors, and cardiac output. Clinical application of TCD are detection of stenosis, occlusion, emboli, thrombsis in intracranial and extracranial arteries and evaluation of cerebral arterovenous malformation, collateral capacity in the circle of Willis, ischemia cerebrovascular disease, stroke patient and vertebrobasilar system.

  • Objective : Unique Internal carotid artery angiographic findings have been found especially in very poor grade aneurysmal subarachnoid hemorrhage[SAH] patients before and during the endovascular coiling. The author investigates their patterns and classifies them into lour subtypes. Methods : Among Hunt&Hess grade IV, V SAH patients, the author could gather eight patients who showed abnormal intracranial circulation in cerebral catheter-based angiography. Results : The author introduces new term 'misery collaterals' first and has classified them into four types with the case illustrations. Type 1 is the worst condition defined as almost no intracranial circulation. Type 2 is the condition of little intracranial circulation with contrast filling just only at vessels of brain base, type 3 is of no or little cortical circulation with contrast filling at bilateral large vessels of brain base through circle of Willis channel and type 4 is of visible bilateral cortical circulation but delayed intracranial circulation time. The prognosis of these eight patients showed misery collaterals were disappointed. Conclusion : These finding can be used as the supportive information in deciding a management plan in poor grade SAH patients.

  • Intracranial lipomas are rare, and most of these tumors are found in the region of the corpus callosum, followed by cerebellopontine angle. We present a case of a intracranial lipoma in 30-year-old man. Brain computed tomography [CT] scan and magnetic resonance images [MRI] showed a mass in the medulla oblongata extending to foramen magnum. The histopathologically, diagnosis of lipoma was confirmed. Although there were several cases of cervical intraspinal lipoma extending into posterior cranial fossa, there have been no previous reports of a lipoma arising from the medulla oblongata that extended into the foramen magnum. We describe a rare case of intradural subpial lipoma in the medulla oblongata with a review of the literature.

  • The advent of endovascular therapy for intracranial aneurysms and the rapid advances in that field have supplanted microsurgical treatment for many intracranial aneurysms. Applying current outcome data and other parameters, nuances of selecting the modality of treatment for intracranial aneurysms are reviewed. Patient factors, such a age, co-morbidities, vasospasm and other medical conditions, are addressed. A custom-tailored multimodality treatment paradigm for the management of ruptured and unruptured aneurysms will maximize the favorable results seen in this difficult patient population.

  • A traumatic spinal subdural hematoma is a rare condition, and only nine cases have been reported until now. We report a rare case of concomitant intracranial hemorrhage and spinal subdural hematoma with a review of the literature. A 45-year-old man was referred to our institute after being stroke by a car. He complained of nausea, headache, back pain, and bilateral sciatica. Brain computed tomography and lumbar spine magnetic resonance images revealed both an intracerbral hemorrhage and a subdural hematoma in the L4 to S1 level. After performing a lumbar spinal puncture and draining the hemorrhagic cerebrospinal fluid (CSF), the intracranial and spinal hematomas were resolved completely without any neruologic deficits.

  • Simultaneous intracranial and spinal subdural hematomas are extremely rare. In most cases, they are attributed to major or minor trauma and iatrogenic causes, such as those resulting from spinal puncture. To the best of the authors' knowledge, there has been only two reports of spontaneous concomitant intracranial and spinal subdural hematomas in a patient receiving anticoagulant therapy who had an absence of evident trauma history. We report on a case of spontaneous concomitant intracranial and spinal subdural hematomas that occurred in association with anticoagulant therapy and present a review of the relevant literature.
