Isolated peripheral-type facial palsy due to pontine cavernoma hemorrhage

Teaching NeuroImages: Isolated peripheral facial palsy due to ipsilateral pontine infarction.

A 72-year-old woman presented left peripheral facial palsy for 1 day. Neurologic examination revealed isolated left peripheral facial palsy (figure 1). She did not have additional pontomedullary symptoms or signs, such as diplopia, abduction weakness, facial sensory loss, vertigo, nystagmus, or dysarthria. A brain diffusion-weighted MRI scan showed a hyperintense signal in the left dorsal pons ...

Pontine supranuclear facial palsy.

Two patients presented with a unilateral supranuclear facial palsy. Additional dysarthria was attributed to the pontine origin documented by magnetic resonance imaging on the contralateral side. The pontine disorder also was indicated by an isolated delay of the blink reflex R1 component or of the masseter reflex. We attribute the facial palsy to a lesion of a supranuclear fiber bundle supplyin...

Peripheral Facial Palsy in Emergency Department

Introduction: Peripheral facial palsy (PFP) is commonly diagnosed in every emergency department. Despite being a benign condition in most cases, PFP causes loss in quality of life mostly due to facial dysmorphia. The etiology of PFP remains unknown in most cases, while medical opinion on epidemiology, risk factors and optimal treatment is not consensual. The aim of this study was to review the ...

Isolated facial palsy due to intra-aural tick (ixodoidea) infestation

Volitional type of facial palsy associated with pontine ischaemia.

A dissociation between voluntary and emotional facial innervation is described in a patient with a pure motor stroke due to a unilateral ischaemic pontine infarction. Voluntary facial innervation of the contralateral orbicularis oris muscle was affected whereas emotionally induced innervation of the same muscle was spared. This report provides evidence that fibres conveying voluntary and emotio...
