To present a step-by-step approach of intraventricular tumors with MRI, based on a number of morphologic imaging criteria. To illustrate the imaging findings of the most commonly encountered intraventricular tumors.

The various histological types of intraventricular tumors may show specific imaging findings, as well as overlapping imaging findings. Becoming acquainted with the specific imaging findings in each type of tumor can help to considerably narrow the differential diagnosis.

Throughout this exhibit, the term ‘intraventricular tumor’ refers to tumors which are macroscopically located inside the ventricular system on MRI images, regardless of their histologic origin from intraventricular structures or the ventricular wall. The most common intraventricular tumors are illustrated, with images acquired with 1,5 T and/or 3T MRI machines. In the imaging section, the tumors are described based on the following imaging criteria: location within the ventricular system presence of a cystic component enhancement pattern presence of blood or calcification The most important imaging...
