[A case of superficial siderosis treated with intravenous and oral hemostatic drugs].

A 39-year-old man suffering from progressive dysarthria, gait disturbance, and sensorineural deafness for 2 years was admitted to our hospital. He scored 28 points on the mini-mental state examination. He had previously undergone surgery at 24 years and 39 years of age for a cerebellar tumor (pilocytic astrocytoma). Superficial siderosis (SS) was diagnosed based on bloody cerebrospinal fluid (CSF) and the findings of T2-weighted head MRI that revealed marginal hypointensity of the surface of the cerebellum, brainstem, and cerebral cortex. After intravenous infusion and the oral use of hemostatic drugs (carbazochrome, tranexamic acid), the CSF became watery clear and his condition improved. Hemostatic drug therapy should be considered for SS.
