Multiple myeloma presenting as cerebral venous sinus thrombosis

A 52-year old lady presented with acute onset headache, seizures, confusion and was found to have anemia, albumin/globulin ratio reversal and cerebral venous sinus thrombosis. On further investigations, multiple myeloma was found to be the underlying cause. The patient recovered fully with anticoagulation and chemotherapy. This case indicates that cerebral venous sinus thrombosis can be an unusual presenting manifestation of myeloma.
