Intraventricular Tumors

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 non-neuroepithelial 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. (C) 2016 Elsevier Inc. All rights reserved.
