Multiple cranial nerve palsies in a case of intracranial plasmacytoma and multiple myeloma: A report

摘要

Multiple myeloma is usually associated with neurological features like peripheral neuropathy and compressive myelopathy. It is unusual for multiple myeloma to present with multiple cranial nerve palsies. We report a case of multiple myeloma with an extramedullary plasmacytoma in the maxillary antrum, which resulted in multiple cranial nerve palsies. The patient was diagnosed to have IgG λ subtype in stage II according to the international staging system (ISS). The patient did not respond to a combination of radiotherapy and chemotherapy.
