Rathke's cleft cyst (RCC) is a rare lesion of the pituitary gland that is often asymptomatic. The objective of this study was to further characterise the presenting symptoms, endocrinopathy and potential for recurrence of this lesion in an Australian population. The files of 12 patients with pathologically confirmed RCCs were reviewed retrospectively.(More)
OBJECTIVE Craniopharyngiomas have traditionally represented a challenge for open transcranial or transsphenoidal microscopic neurosurgery because of their anatomical location and proximity to vital neurovascular structures. The extended endoscopic endonasal transsphenoidal approach has been more recently developed as a potentially surgically aggressive, yet(More)
INTRODUCTION Cavernous carotid aneurysms can cause significant symptomatology through mass effect and may rupture, resulting in carotid-cavernous fistula or epistaxis. Traditional treatment options included endovascular or surgical parent vessel occlusion, or embolization; in the last decade, the development of flow-diverting stents has changed the(More)
Inflammation is a critical process behind cerebral aneurysm formation and rupture. Tumor necrosis factor alpha (TNF-α) is a key immune modulator that has been implicated in cerebral aneurysm pathophysiology. This may occur through TNF-α-mediated endothelial injury, smooth muscle cell phenotypic modulation, recruitment of macrophages, activation of(More)
BACKGROUND Endovascular treatment of wide-necked aneurysms is challenging. Stent-assisted coiling (SAC) is associated with increased complications and requires dual antiplatelet therapy. OBJECTIVE To compare treatment of unruptured, wide-necked aneurysms with a dual-microcatheter technique (DMT) versus SAC. METHODS Between 2006 and 2011, 100 patients(More)
OBJECT Atypical (WHO Grade II) meningiomas comprise a heterogeneous group of tumors, with histopathology delineated under the guidance of the WHO and a spectrum of clinical outcomes. The role of postoperative radiotherapy for patients with atypical meningiomas who have undergone gross-total resection (GTR) remains unclear. In this paper, the authors sought(More)
OBJECTIVE To assess the advantages and limitations of the endoscopic endonasal approach to anterior skull base meningiomas, a minimally invasive approach that avoids extensive bone drilling, brain retraction, and manipulation of nerves and critical vessels, versus open transcranial surgery. METHODS A MEDLINE (2000-2010) search was performed to identify(More)
OBJECT Endoscopic transsphenoidal surgery is expanding in acceptance, yet postoperative CSF leak rates remain a concern. This study presents the Cornell closure protocol, which has yielded significantly lower postoperative CSF leak rates compared with prior reports, as an algorithm that can be used by centers having difficulty with CSF leak. METHODS A(More)
OBJECTIVE Esthesioneuroblastomas represent a surgical challenge because of their anatomical location, the necessity of achieving negative margins, and the often-cosmetically disfiguring transfacial approaches needed. Recently, expanded endonasal endoscopic approaches have been developed, either alone or in combination with a craniotomy. We conducted a(More)
BACKGROUND AND PURPOSE Preoperative embolization for intracranial meningiomas offers potential advantages for safer and more effective surgery. However, this treatment strategy has not been examined in a large comparative series. The purpose of this study was to review our experience using preoperative embolization to understand the efficacy, technical(More)
