280 Schmidt, Meic H.Spinal extradural arachnoid cysts: clinical, radiological, and surgical featuresExtradural arachnoid cysts in the spine are rare and are seldom a cause of spinal cord compression. They are thought to arise from congenital defects in the dura mater, and they almost always communicate with the intrathecal subarachnoid space through a small defect in the dura. The mainstay of trea...Spinal extradural arachnoid cyst; Spinal meningeal cyst; Neurogenic claudication2007

282 Couldwell, William T.; Harnsberger, H. RicSpontaneous regression of a cystic cavum septum pellucidumA persistent cavum septum pellucidum (CSP) is present in ~0.73% of adults, although its incidence ranges from 0.14 to 18.9% depending on the detection method. Cystic CSP is even rarer. A cyst causing mass within the CSP can obstruct the intraventricular foramen, leading to blockage of CSF flow and p...Cavum septum pellucidum; Cyst; Spontaneous regression; Decompression2006

W.Sporadic osteochondroma of the cervical spineOsteochondroma is the most common benign tumor of bone, but axial skeleton involvement is uncommon and usually indicates a hereditary cause such as osteochondromatosis (hereditary multiple exostosis). 1 Approximately 7% of hereditary osteochondromas occur along the vertebral column, which is double...2006
284 Couldwell, William T.Strategies for the management of nonsecreting pituitary adenomasThe two objectives of treating pituitary tumors are: (1) relief of signs and symptoms attributable to mass effect, and (2) correction of hypo - or hypersecretion of adenohypophyseal hormones.7 When nonsecreting tumors are specifically considered, correction of endocrine abnormalities may be of les...Pituitary adenomas; Transsphenoidal surgery1991
285 Couldwell, William T.Stress and burnout: insidious influencesA career in neurosurgery may take a substantial toll on an individual?s body and mind.

288 Couldwell, William T.Submandibular-infratemporal interpositional carotid artery bypass for cranial base tumors and giant aneurysmsCerebral revascularization is an important strategy in the surgical management of some complex cranial base tumors and unclippable aneurysms. A highflow bypass may be necessary in planned carotid occlusion or sacrifice. The cervical-to-supraclinoid internal carotid artery bypass or cervical carotid-...Internal carotid artery; Cranial base tumors; Giant aneurysms; Interpositional bypass; Surgical approach; Radial artery; Revascularization; Saphenous vein; Submandibular infratemporal bypass2006
289 Couldwell, William T.Surgical approaches for resection of vestibular schwannomas: Translabyrinthine, retrosigmoid, and middle fossa approachesSurgical removal remains one of the key treatment modalities for vestibular schwannomas. A team approach between a neurotologist and a neurosurgeon offers the patient the expertise of both specialties and maximizes the chances for an optimal outcome. Vestibular schwannomas can typically be resected ...2012-01-01
290 Couldwell, William T.Surgical approaches to petroclival meningiomas part I: upper and midclival approachesStrictly considered, petroclival meningiomas represent only a percentage of the 10% of all intracranial meningiomas that reside in the posterior fossa.
