Intracranial hemorrhage as initial manifestation of plasma cell myeloma: A case report.

This is the case of a previously healthy 48 year-old male whom presented with mild confusion, low-grade headache, and left sided weakness. Computed tomography of the head revealed a large acute right frontal lobe intracranial hemorrhage (ICH) and intraventricular extension, with normal vascular imaging. Initial laboratory testing was inconsequential. The patient required emergent evacuation, with pathology revealing only elements of a hematoma. Further laboratory testing and bone marrow biopsy results confirmed the diagnosis of plasma cell myeloma. Other systemic signs/symptoms of this disease were notably absent. This report provides the first description of an ICH as the presenting manifestation of plasma cell myeloma (PCM; multiple myeloma).
