The finding of intracranial, extramedullary plasmacytoma is rare in multiple myeloma, especially with dural involvement. Meningioma remains the most common intracranial extra-axial mass. We report a case of a 39-year-old male who presented with intracranial, extra-axial mass found later to be dural plasmacytoma and additional multiple lesions on skeletal survey, leading to a diagnosis of multiple myeloma. The objective of this case is to increase awareness of the possibility of dural plasmacytoma as a differential diagnosis of meningioma and a harbinger of multiple myeloma. Magnetic resonance imaging plays a vital role in the detection of additional lesions in individuals while excluding multiple myeloma.
