The Kernohan syndrome results from the compression of the cerebral peduncle against the tentorium cerebelli. This phenomenon represents a relevant clinical sign of transtentorial herniation due to an ipsilateral expansive lesion. We reported a case of a 50-year-old woman with a right temporal meningioma who developed a false localizing hemiparesis, which improved after microsurgical resection. This case emphasizes the mechanism and rarity of this pathology.
