spinothalamic tracts

spinothalamic tracts

The nerve bundles running up the spinal cord carrying sensory impulses to the great sensory nucleus of the basal ganglia-the THALAMUS.

The descending corticospinal tracts and ascending dorsal columns decussate in the medulla while the ascending lateral spinothalamic tracts decussate within one or two levels of the entrance of the dorsal roots.
Symptoms of ASA syndrome include complete motor loss below the level of the lesion as well as loss of pain and temperature sensation due to loss of the corticospinal and spinothalamic tracts, respectively; this patient exhibited findings consistent with ASA syndrome.
It is also demonstrated that genetic ablation of oligodendrocytes in mice, which causes axonal pathology in the spinal dorsal horn and spinothalamic tracts, leads to the development of neuropathic pain behavior [109].

Our patient presented with acute onset of fever with involvement of bilateral pyramidal, and anterolateral spinothalamic tracts without any evidence of posterior column involvement.
Neurological examination revealed: increased muscle tone with difficulties in passive movement and 2/5 grade muscle power in both lower limbs; loss of pain, temperature and pressure (mild degree) sensations below the umbilicus suggestive of lateral and ventral spinothalamic tract involvement.
Brown-Sequard syndrome, first reported in 1849, is characterised by hemisection of the cord with disruption of the descending lateral corticospinal tracts resulting in ipsilateral hemiplegia, and damage of the ascending lateral spinothalamic tracts (which cross within one or two levels of the dorsal root entrance) resulting in contralateral loss of pain and temperature.
This finding suggests an early involvement of the spinothalamic tracts (pain and temperature nerve pathways), Dr.
Brown-Sequard syndrome is characterised by damage of the ascending lateral spinothalamic tracts (which cross within one or two levels of the dorsal root entrance) resulting in contralateral loss of pain and temperature.
Given the central location, in proximity to spinothalamic tracts, sensory symptoms are frequently observed.
