Subfalcine herniation – http://id.who.int/icd/entity/834482396

Subfalcine herniation refers to mass effect in the high lateral frontal or parietal lobe forcing the cingulate gyrus up against and then under and past the falx cerebri. This produces a personality change and mild contralateral leg weakness, which becomes more pronounced if the herniation is of sufficient magnitude to compress the anterior cerebral artery (ACA) against the falx and cause an ACA infarct.
