Solitary craniocerebral plasmacytoma mimicking a meningioma

Abstract

When the skull or the central nervous system is involved in plasma cell dyscrasia, there is usually the presence of the disease elsewhere in the bone or in the soft tissues. Solitary craniocerebral lesion is therefore uncommon. We present below, a case of a forty year old male with complaints of skull swelling of four years duration which was diagnosed to be a  solitary plasmacytoma without  the systemic disease. The imaging similarity between dural plasmacytoma which occurs as a solitary lesion and a meningioma often causes a diagnostic dilemma and may only be distinguished histologically. Also, appropriate diagnosis is important in order to distinguish this rather benign tumor from its systemic counterpart as their prognoses differ.
