What is the explanation for the loss of pain and temperature on the opposite side of the injury?

The loss of sensation on the opposite side of the lesion is because the nerve fibers of the spinothalamic tract (which carry information about pain and temperature) crossover once they meet the spinal cord from the peripheries.

Where would a lesion be located that results in contralateral loss of pain and temperature sense in the body and ipsilateral loss of pain and temperature sense in the face?

The most common pattern of sensory abnormality in patients with lateral medullary ischaemia is loss of pain and heat sensation on the ipsilateral side of the face and the lower part of the body on the contralateral side. Sensory loss can also involve touch.

Is Brown-Séquard syndrome ipsilateral contralateral?

Patients with Brown-Séquard syndrome suffer from ipsilateral upper motor neuron paralysis and loss of proprioception, as well as contralateral loss of pain and temperature sensation. A zone of partial preservation or segmental ipsilateral lower motor neuron weakness and analgesia may be noted.

What happens in Brown-Séquard syndrome?

Brown-Sequard syndrome (BSS) is a rare neurological condition characterized by a lesion in the spinal cord which results in weakness or paralysis (hemiparaplegia) on one side of the body and a loss of sensation (hemianesthesia) on the opposite side.

What is cord syndrome?

Central cord syndrome (CCS) is an incomplete traumatic injury to the cervical spinal cord – the portion of the spinal cord that runs through the bones of the neck. This injury results in weakness in the arms more so than the legs.

What is lateral cord syndrome?

Posterior cord syndrome is a rare type of incomplete spinal cord injury that affects the dorsal or posterior columns of the spinal cord, which are responsible for the perception of vibration, fine-touch and body positioning (i.e. proprioception).

What causes Wallenberg syndrome?

Wallenberg’s syndrome is a neurological condition caused by a stroke in the vertebral or posterior inferior cerebellar artery of the brain stem.

What is the difference between paresis and Plegia?

Paresis describes weakness or partial paralysis. In contrast, both paralysis and the suffix -plegia refer to no movement.

What is sacral sparing?

What Does Sacral Sparing Indicate? Sacral sparing is used to help diagnose whether a person’s spinal cord injury is complete or incomplete. With complete spinal cord injuries, all sensory and motor functions below your level of injury are affected because signals from the brain cannot travel past the spinal lesion.

What is Flavum?

One of a series of bands of elastic tissue that runs between the lamina from the axis to the sacrum, the ligamentum flavum connects the laminae and fuses with the facet joint capsules. As we age, the ligament loses elastin, and this allows the ligament to encroach on the canal.

Is Wallenberg syndrome permanent?

Complications of Wallenberg Syndrome Stroke syndromes can cause permanent disability and affect normal daily functioning, per StatPearls. The most common complications of posterior circulation strokes include: Aspiration pneumonia.
