We report a case of malignant peripheral nerve sheath tumor in the cauda equina, which was associated with neurofibromatosis type I. The tissue specimen acquired from the mass of cauda equina was transformed from benign to malignant form within 3 months. We report this case with review of the literatures.

OBJECTIVE: The three-dimensional computed tomographic angiography(3D-CTA) images are not commonly used than the conventional digital subtraction angiography(DSA) as a postoperative examination to identify a remnant neck or whether the parent and branching arteries and the cerebral aneurysm are clipped together. We suggest that the neurosurgeons themselves can reconstruct 3D images using 3D reconstruction program in their personal computers and evaluate the aneurysm neck clipping state more precisely than DSA. METHODS: Both 3D-CTA and DSA images were obtained postoperatively on 40 patients with 45 cerebral aneurysms. 38 aneurysms were clipped by single clip, 6 by double clips, and 1 by triple clips. We compared 3D-CTA images, which are made by easy and noninvasive method of the new software to ascertain postoperatively the perfection of aneurysm neck clipping performed with titanium clips, with DSA. RESULT: Out of the total 45 cerebral aneurysms clipped with titanium clips, 3D-CTA clearly showed the state of the clipped necks and the parent and branching arteries of 44 aneurysms in 39 cases. There were three cases in which the remnant necks were found in 3D-CTA, but two of them were not identified in DSA. There was one patient who had cerebral aneurysms requiring 3 clips, resulting in a poor view of the remnant necks since the clips covered the necks. CONCLUSION: In case using one or two titanium clips for the aneurysmal clipping, 3D-CTA may be a reliable alternative method to DSA in the postoperative evaluation to define the cerebral aneurysm neck and the surrounding vessels after clipping.

Intracranial aneurysms are the most common source of nontraumatic subarachnoid hemorrhage (SAH) in elderly patients. Despite the fact that more patients who present with SAH are middle-aged, the age-specific incidence for SAH increases with increasing age. The elderly patients with aneurysmal SAH have a trend toward poor outcome. Furthermore there are age-associated factors that increase perioperative and postoperative risks. In this paper, authors will review and discuss the reason why older patients have a poorer outcome and management for aneurysmal SAH in geriatric patients.

In a series of 375 bilateral carotid angiographies, two accessory middle cerebral arteries, one duplication of the middle cerebral artery demonstrated on the angiography were reviewed relative to the pertinent literature. These anomalous middle cerebral arteries are very rare. We reported a case of duplication of the middle cerebral artery at 1993 which was first one to be reported in Korea. At present, we report two additional anomalous accessory middle cerebral arteries. Among these, one was accessory middle cerebral artery originated from the horizontal portion of the anterior cerebral artery, and the other originated from the A2 segment of the anterior cerebral artery. Both of these gave rise to some perforating arteries.
