An anatomical-angiographic classification for carotid-cavernous sinus fistulas is introduced and a series of 14 patients with spontaneous carotid-cavernous sinus fistulas is reviewed to illustrate the usefulness of such a classification for patient evaluation and treatment. Fistulas are divided into four types: Type A are direct high-flow shunts between the(More)
Intradural perimedullary arteriovenous fistulas (Type IV spinal cord arteriovenous malformations (AVM's)) are rarely reported in the literature and occasionally are classified together with Type II AVM's as intradural spinal cord AVM's. The authors report eight cases of Type IV spinal cord AVM's managed over a 2-year period. Seven of these AVM's were(More)
A series of 12 patients with infectious intracranial aneurysms is presented, and a number of unusual features of the disorder are emphasized. A comparison of characteristics of the aneurysms and clinical course is made between patients with and without infective endocarditis. Most of the unusual characteristics of infectious aneurysms, including rare(More)
Effective classicality of a property of a quantum system can be defined using redundancy of its record in the environment. This allowes quantum physics to approximate the situation encountered in the classical world: The information about a classical system can exist independently from its state. In quantum theory this is no longer possible: In an isolated(More)
OBJECT Indications for intraoperative angiography during aneurysm surgery remain unclear. To define its use, the authors report the results of a prospective study in which this modality was used in all patients undergoing surgery for intracranial aneurysms. METHODS Intraoperative angiography was performed prospectively in the surgical treatment of 517(More)
OBJECTIVE We describe a combined simultaneous approach to giant pituitary tumors and present a review of 10 patients undergoing this procedure with emphasis on patient selection, surgical technique, and results. METHODS A retrospective review was performed of patients who had undergone a combined, simultaneous transsphenoidal and pterional craniotomy(More)
The authors report on 32-year-old woman with a history of a previously resected suprasellar clear cell meningioma (CCM), who returned to their institution after 3 years suffering from progressively worsening leg and back pain associated with leg weakness and bowel and bladder dysfunction. A magnetic resonance image of the thoracic and lumbar spine(More)
A 58-year-old woman had Cushing's disease with elevated plasma adrenocorticotrophin and an intrasellar tumor. Light microscopy showed that the tumor was a gangliocytoma containing immunoreactive corticotrophin-releasing factor accompanied by pituitary corticotroph hyperplasia. Ultrastructural examination identified an intimate association and desmosomal(More)
OBJECTIVE Tentorial dural arteriovenous malformations (DAVMs) are uncommon lesions associated with an aggressive natural history. Controversy exists regarding their optimal treatment. We present a single-institution series of tentorial DAVMs treated during a 12-year period, address the current controversies, and present the rationale for our current(More)
There is a growing body of evidence in the literature suggesting that cavernous malformations of the central nervous system may develop after neuraxis irradiation. The authors discuss the case of a 17-year-old man who presented with progressive back pain and myelopathy 13 years after undergoing craniospinal irradiation for a posterior fossa medulloblastoma.(More)
