Multiple myeloma is generally a neoplastic plasma cell disorder of the old age. It seldom attacked young people or manifested intracranial plasmacytomas. Here we report a 28-year-old young patient of plasma cell dyscrasia who presented multiple plasmacytomas of bones while sparing bone marrow. Cerebral involvement with intratumorous hemorrhage complicated the clinical course. The unique clinical features are presented and literature is reviewed.
