Kernohan-Woltman Notch Phenomenon (KWNP) is a neurologic picture caused by the compression of the contralateral cerebral peduncle on the free edge of the tentorium resulting from the displacement of the brain tissue at the ipsilateral side of a paradoxically supratentorial lesion leading to mydriasis and hemiparesis or hemiplegia ipsilateral to a supratentorial space occupying mass [1]. This phenomenon is usually reported secondary to brain tumors and severe head injuries [2]. The development of KWNP secondary to chronic subdural hematomas has been rarely reported and there is no reported case from Ghana where this case is being reported from. We report this case of Kernohan-Woltman notch phenomenon in a 50 year old man with a chronic subdural hematoma who was brought to the Emergency Department in a comatose state.
