Abstract The Kernohan-Woltman notch phenomenon (KWNP) refers to an intracranial lesion
causing massive side-to-side mass effect which leads to compression of the contralateral …

Kernohan–Woltman notch phenomenon (KWNP) is a false localising sign which may still
cause diagnostic confusion. It was first described by Kernohan and Woltman in 1929 …

Purpose This works comprehensively analyses a modern cohort of patients with ipsilateral
hemiparesis (IH) and discusses the pathophysiological theories elaborated to explain this …

Introduction Ipsilateral hemiparesis (IH) can be defined as a paradoxical dysfunction of the
first motor neuron involving the extremities on the opposite side to that expected, given the …

OBJECTIVE AND IMPORTANCE: Compression of the cerebral peduncle against the
tentorial incisura contralateral to a supratentorial mass lesion, the so-called Kernohan …

We report two cases of Kernohan's notch phenomenon secondary to chronic subdural
hematoma detected by MRI. In the first case, the patient was drowsy with an oculomotor …

Background: Hemiparesis ipsilateral to a mass-occupying lesion can be due to Kernohan-
Woltman Notch Phenomenon (KWNP). This syndrome implies a false-localizing sign …

Posttraumatic ipsilateral motor deficits are rare and raise etiologic and prognostic concerns
for the rehabilitation team. We present two cases with an unusual central neurologic cause …

✓ A 69-year-old man presented with mild left-sided hemiparesis of 2 years' duration. A
computerized tomography scan revealed a left-sided chronic subdural hematoma and a …

Objective and importance: We report the case of a 73-year-old patient who presented a right
motor deficit caused by an ipsilateral acute subdural hematoma. A magnetic resonance …
