CRANIOCEREBRAL PLASMACYTOMA - MR FEATURES

We report the MR imaging findings in two patients with solitary cranio cerebral plasmacytoma, a benign plasma cell tumor that can arise from the skull, the dura, or, rarely, the brain. In both patients, the lesi on was extraaxial and nearly isointense with gray matter on T2-weighte d MR images, and diffusely enhanced after administration of contrast m aterial, bearing some similarities to meningioma, A diagnosis of solit ary craniocerebral plasmacytoma should be considered when a mass with these imaging features is seen, because total excision may not be nece ssary for this radiosensitive tumor.
