A Case of Relapsed Multiple Myeloma Presented as lntracranial Extramedullary Plasmacytoma / 대한혈액학회지

ABSTRACT

Intracranial plasmacytoma presented by extramedullary involvement of multiple myeloma is rarely reported. Neurologic complications by intracranial extramedullary plasmacytomas are cranial nerve palsy, visual disturbance, vertigo, nystagmus, headache, paralysis, mental change and etc. We experienced a case of relapsed multiple myeloma presented as intracranial extramedullary plasmacytoma. Brain magnetic resonance imaging(MRI) disclosed a large soft tissue mass involving the sphenoidal sinus and cavernous sinus which invaded optic chiasma, occulomotor nerve and pituitary gland. Relapsed multiple myeloma with intracranial extramedullary plasmacytoma was confined by trans-sphenoidal biopsy and urine electrophoresis. Neurologic complications of the patient was improved after cranial radiotherapy and systemic chemotherapy.
