[Transient neurological deficits in a patient with chronic subdural hematoma].

A 62-year-old, right-handed man was diagnosed with asymptomatic bilateral chronic subdural hematomas and underwent hematoma removal on the left side only. At 1 month after surgery, he was admitted to our hospital because he began to have one or two attacks/day of apraxia of speech and dysesthesia of the right hand with a duration of approximately 5 ‍min. The left hematoma had not re-expanded, but fluid-attenuated inversion resonance imaging showed hyperintense lesions in the sulci adjacent to the hematoma.

Hemichorea induced by a sphenoid ridge meningioma.

Background: Movement disorders are rare in brain tumors. We describe a 45-year-old woman with hemichorea, a concomitant contralateral sphenoid ridge meningioma.

Case Description: The meningioma enlarged as her hemichorea worsened, and after meningioma resection, the hemichorea gradually subsided.
