Clinical Significance of Venous Anomalies in Syndromic Craniosynostosis.

Background: The pattern of cranial venous drainage in syndromic craniosynostosis is unpredictable and not adequately understood. Collateral channels substitute for stenotic venous sinuses and pose potential risk for surgical intervention. The purpose of this study was to analyze the patterns of venous drainage in patients with syndromic craniosynostosis and their influence on operative planning and morbidity.

Endovascular treatment of a large ruptured middle cerebral artery bifurcation aneurysm in a 5-week-old infant: case report.

Ruptured intracranial aneurysms are extremely rare in infants. The optimal treatment strategy is not well established. Both microsurgical and endovascular techniques and strategies have been tried, and in the literature there is a significant variability in outcome.

Malignant carotid body tumor presenting with myelopathy: case report.

Malignant carotid body tumors are rare, with spread of the tumor mostly noted in regional lymph nodes. Vertebral metastases are an exceedingly rare presentation, only reported in isolated case reports, and present a diagnostic and management challenge. A case of widespread vertebral metastasis, presenting with myelopathy, from a carotid body tumor is discussed in this paper, along with management strategies.

Cerebrospinal fluid leaks and encephaloceles of temporal bone origin: nuances to diagnosis and management.

Objective: Temporal bone encephalocele has become less common as the incidence of chronic mastoid infection and surgery for this condition has decreased. As a result, the diagnosis is often delayed, and the encephalocele is often an incidental finding. This situation can result in serious neurologic complications with patients presenting with cerebrospinal fluid leak and meningitis.

Hemorrhagic ganglioglioma of the posterior fossa: case report.

Gangliogliomas are rare tumors of the central nervous system that are usually found in the supratentorial compartment, although cases throughout the nervous system have been described. They are generally low-grade malignancies that are amenable to cure by surgical resection. Most manifest as seizures, though, based on location, they can present with focal neurological deficits.

Targeting cancer stem cells in glioblastoma multiforme using mTOR inhibitors and the differentiating agent all-trans retinoic acid.

Glioblastoma multiforme (GBM), the most aggressive primary brain tumor, portends a poor prognosis despite current treatment modalities. Recurrence of tumor growth is attributed to the presence of treatment-resistant cancer stem cells (CSCs). The targeting of these CSCs is therefore essential in the treatment of this disease.

Abnormal venous drainage in syndromic craniosynostosis and the role of CT venography.

Objective: Venous hypertension is emerging as a significant contributor to intracranial pressure in children with syndromic craniosysnostosis. This is associated with jugular foramen stenosis or atresia and with the development of collateral emissary veins. We demonstrate how computed tomography venography can document the prevalence of these emissary veins and how their visualisation plays an important role in operative planning.
