[Diagnostic imaging in the evaluation of masses developing in the cerebral ventricles]

Abstract

CT scan and MR imaging of intraventricular masses are discussed in this work. The lesions affecting this region may be of neoplastic, vascular or phlogistic origin. CT scan and MR imaging are useful for diagnosis and management of these lesions. Intraventricular masses are well documented by high resolution CT scan after administration of endo-rachideal metrizamide, during ventriculographic studies. This technique gives important informations about peripheral relationship of intraventricular masses with increased liquoral fluid. MR imaging is also available for characterizing pathologic tissues, and for detecting the anatomic relationships between pathologic and normal structures.
