Intracranial plasmacytoma arising from dura mater secondary to multiple myeloma and presenting with sudden lethal intracerebral hemorrhage: A case report and literature review.

Background: Intracranial and central nervous system’s involvement with multiple myeloma (MM) is a clinically rare manifestation. Furthermore, the development of intracranial plasmacytoma without bone involvement is much rarer. Herein, we report the case of massive intracerebral hemorrhage form intracranial plasmacytoma that arose from the dura mater without bone involvement. Case Description: A 71-year-old woman, who had been diagnosed as MM and treated 2 years prior, developed sudden lethal intracerebral hemorrhage from the intracranial plasmacytoma. Massive hemorrhage was observed after a rapid tumor growth in the middle fossa. Immediate hematoma evacuation and tumor resection allowed the patient to avoid severe neurological deficits and lethal conditions. Conclusion: A close follow-up by neuroimaging studies is essential in cases of intracranial plasmacytoma in MM patients and early intervention with surgical resection or radiotherapy should be considered.
