UNLABELLED Human epidermal growth factor receptor type 2 (HER2) is a well-established tumor biomarker that is overexpressed in a wide variety of cancers and that serves as a molecular target for therapeutic intervention. HER2 also serves as a prognostic indicator of patient survival and as a predictive marker of the response to antineoplastic therapy. The(More)
BACKGROUND Paraclinoid or ophthalmic segment aneurysms arise from the internal carotid artery (ICA) between the roof of the cavernous sinus and the origin of the posterior communicating artery. Clinoid aneurysms arise between the proximal and distal carotid dural rings. The complex anatomy of clinoid and paraclinoid ICA aneurysms often makes them difficult(More)
BACKGROUND Giant aneurysms originating from the proximal anterior cerebral artery (A1) are extremely rare. Only 12 cases have been reported previously. CASE REPORT A case of giant A1 aneurysm, which occurred in a patient with a progressive visual loss, is presented. The previous 12 cases are reviewed and discussed. This patient was treated by trapping and(More)
BACKGROUND Tentorial dural arteriovenous fistulas (AVFs) are uncommon lesions usually treated surgically using a subtemporal exposure with division of the tentorium. This exposure requires significant retraction of the temporal lobe and has the possibility of significant arterialized venous bleeding if a draining vein is accidentally cut during division of(More)
Idiopathic orbital inflammation or orbital pseudotumor with intracranial extension is a rare condition. It consists of a nonspecific infiltrate of the fatty tissue of the orbit that extends through one or more foramina into the adjacent intracranial tissue. The lesion mimics an infectious or neoplastic lesion. The authors present a case involving the(More)
A case of a 21-year-old patient with a recurrent pleomorphic xanthoastrocytoma with invasion of the tentorium and falx cerebri is reported. Dural attachment has been reported in some cases. Invasion of the dura of the falx cerebri and complete infiltration of the left tentorium by the tumor were found intraoperatively. This is the first case in the(More)
OBJECTIVE The purpose of this investigation was to study the epidemiology of chronic and subacute subdural hematoma in an adult population and associated factors such as treatment, recurrence, seizures, complications, and outcome. METHODS We retrospectively reviewed 267 consecutive cases operated for a suspected diagnosis of chronic or subacute subdural(More)
BACKGROUND Aneurysms are primarily treated with surgical clipping. Unclippable aneurysms are at risk of recurrent bleeding similar to the natural history of ruptured aneurysms. Aneurysm reinforcement with muslin and ethyl 2-cyanoacrylate may provide a safe and useful alternative to reduce the rebleeding rate in those aneurysms found to be unclippable at(More)
The author describes the anatomy of the region of the petrous apex giving emphasis to the limits of surgical resection. The cochlea, located at the apex of the angle formed by the intersection of a line along the sphenopetrosal groove and a line from the facial hiatus to the internal auditory canal, has to be protected to preserve hearing.
