title: Intraventricular Tumors.
abstract: Intraventricular tumors represent a unique group of intracranial neoplasm separate from the classic division as intra- vs extra-axial masses. Intraventricular tumors are unique because of the diverse pathologic spectrum, including the entire gamut of neuroepithelial and nonneuroepithelial tumors. Most of these tumors are clinically benign presenting with headaches or signs and symptoms of hydrocephalus. Computed tomography and magnetic resonance imaging play a pivotal role in diagnosis and neurosurgical guidance. Though, practically any intracranial tumor can have an intraventricular location, we would be discussing the common 8 tumors, which together constitute more than 90% of intraventricular masses. Demographics, clinical and imaging findings, are together very useful in narrowing down the differential.
