Kernohan-Woltman Notch Phenomenon Related to Chronic Subdural Hematoma: A Case Report

Abstract

Kernohan-Woltman notch phenomenon defines the neurological picture caused by a compressive injury of the cerebral peduncles at the tentorial edge due to the contralateral supratentorial lesion and leads to ipsilateral hemiparesis or hemiplegia and mydriasis. We have represented this case of Kernohan-Woltman notch phenomenon that developed secondary to chronic subdural hematoma in a 88-year-old patient as a very rarely reported case. We conclude that advanced brain atrophy contributes to the formation of Kernohan-Woltman notch phenomenon resulted from chronic subdural hematoma. Additionally, investigation of cerebral peduncles via magnetic resonance imaging is important in determination of the clinical picture and evaluation of the response to the treatment in such cases.
