Summary: We present the MR imaging findings in a pa-tient with symptoms of increased intracranial pressure and a mass in the left lateral ventricle. The mass showed in-creased signal intensity on T1-weighted images and low sig-nal intensity on T2-weighted images. The histologic diag-nosis was that of melanoma, and detailed physical and funduscopic examinations disclosed no evidence of a pri-mary lesion. We believe that the mass was a primary in-traventricular melanoma, possibly arising from the choroid plexus, and we discuss the mechanisms that may be re-sponsible for its occurrence in this location. Primary malignant melanomas most commonly originate in the skin, mucosa, and the choroid in the eyes (1, 2). In most instances, melanomas in-v...
