Various Tumors in the 4th Ventricle in Adults: MRI Findings
نویسندگان
چکیده
children but rare in adults. In addition, the disease categories encountered differ according to the patient’s age; in adults, the most common fourth ventricular neoplasm is metastasis (1). The most frequent primary intraventricular tumor of the posterior fossa is the ependymoma; other tumors include choroid plexus papillomas and an occasional meningioma (2). Subependymomas can occur in the inferior fourth ventricle near the obex and are usually found incidentally in older patients (1). This paper describes the various tumors located mainly in the fourth ventricle in adults, and reviews their clinical presentation and the radiological findings.
