Kestle, John R. W. | High incidence of tumor dissemination in myxopapillary ependymoma in pediatric patients | P Myxopapillary ependymomas (MPEs) have historically been thought to be benign tumors occurring most frequently in adults. Only 8 to 20% of these tumors occur in the first two decades of life, making this tumor a rarity in pediatric neurosurgery. Five patients with intraspinal MPEs were treated by t... | 2005-01 | |

Couldwell, William T. | History and evolution of transsphenoidal surgery | Initial attempts at transcranial approaches to the pituitary gland in the late 1800s and early 1900s resulted in a mortality rate that was generally considered prohibitive. Schloffer suggested the use of a transsphenoidal route as a safer, alternative approach to the sella turcica. He reported the f... | Neurosurgical history; Transsphenoidal surgery; Pituitary tumor | 2001 |

Couldwell, William T.; Osborne, Anne G. | Hypertrophic olivary degeneration after surgical removal of cavernous malformations of the brain stem: report of four cases and review of the literature | Background: Hypertrophic olivary degeneration (HOD) is a pathological phenomenon that occurs after injury to the dentato-olivary pathway. Its hallmarks include hypertrophy of the olive with increased T2 signal intensity on magnetic resonance imaging, and often manifests with palatal tremor and osci... | Hypertrophic olivary degeneration; Surgery; Cavernous malformation; Brainstem | 2008 |

Couldwell, William T.; Gillespie, David L.; Jensen, Randy L. | Identification of hypoxia-induced genes in a malignant glioma cell line (U-251) by cDNA microarray analysis | Overcoming the metabolic restrictions of hypoxia may allow the progression of lower-grade tumors to glioblastoma multiforme. Our findings of up-regulation of HIF-1α and its downstream targets VEGF, GLUT-1, and CAIX in higher-grade gliomas support this hypothesis. We compared the gene expression pro... | Glioblastoma multiforme; U-251; Hypoxia; Microarray analysis; Brain tumor; Depp; Astrocytoma | 2007 |
