A modified stereotactic frame as an instrument holder for frameless stereotaxis: Technical note

Arun Angelo Patil

Date of publication: 11-Oct-2010

Background:In order to improve the targeting capability and trajectory planning and provide a more secure probe-holding system, a simple method to use a stereotactic frame as an instrument holder for the frameless stereotactic system was devised.

A patient with multiple synchronous gliomas of distinctly different grades and correlative radiographic findings

Fadi Nakhl, Edwin M. Chang, John S.C. Shiau, Anthony Alastra, Monika Wrzolek, Marcel Odaimi, Mark Raden, Jamie E. Juliano

Date of publication: 16-Sep-2010

Background:Multiple gliomas represent approximately 2 to 5% of all high-grade gliomas which are categorized as multifocal or multicentric depending on the timing, location and pattern of spread. We present a patient with bi-hemispheric, noncontiguous, low- and high-grade gliomas proven by biopsy. She underwent surgical excision and radiotherapy, but unfortunately succumbed to her disease shortly thereafter.

A ruptured internal carotid artery aneurysm located at the origin of the duplicated middle cerebral artery associated with accessory middle cerebral artery and middle cerebral artery aplasia

Naoki Otani, Hiroshi Nawashiro, Nobusuke Tsuzuki, Hideo Osada, Takamoto Suzuki, Katsuji Shima, Kanji Nakai

Date of publication: 16-Sep-2010

Background:Intracranial vascular anomalies involving the middle cerebral artery (MCA) are relatively rare, as such knowledge will be helpful for planning the optimal surgical procedures.

Bizarre depressed skull fracture by a tile fragment in a young child, causing superior sagittal sinus injury

Jacob Eapen Mathew, Alok Sharma

Date of publication: 16-Sep-2010

Background:Head injuries following fall from height are not very uncommon in developing countries due to a lack of safety standards. We describe this bizarre injury by a tile fragment penetrating the superior sagittal sinus (SSS) and its successful surgical management.

A misleading distal anterior cerebral artery aneurysm

Alexander G. Weil, Nancy McLaughlin, Paule Lessard-Bonaventure, Michel W. Bojanowski

Date of publication: 16-Sep-2010

Background:Aneurysmal rupture causing pure acute subdural hematoma (aSDH) is rare. In the four previously reported cases of distal anterior cerebral artery (ACA) aneurysm resulting in pure aSDH, blood distribution in the interhemispheric (IH) space has systematically incriminated the distal ACA as the source of rupture. We present a misleading case of a distal ACA rupture resulting in convexity aSDH with minimal IH blood.
