  • Abstract
  • Look Inside

Recently we examined a interesting case hav-ing syndrome as follows;

1) right facial palsy and abducent paralysis.

2) disturbance of vestibular function. (right side)

3) horizontal nystagmus towards right.

4) left hemihypesthesia (pain, touch, tempera-tur) on face.

5) disturbance of taste. (left side)

Analysing above mentioned syndrome, dorso-medial portion of lower pons may be considered as its lesion.

From this case, a certain results concerning to pathways in central nervous system will be drawn out.

1) The central pain fibres of trigeminal nerve (Walker, Kuru) passes inner side of dorso-lateral spino-thalamic tract at the lower region of pons, and theseare separated in this level each other.

2) Dorsal tract (Wallenberg) passes inner side of ventro medial spino-thalamic tract at the lower region of pons, and these are not unit-ed in this level.

3) The central pathway of taste finishes contral-ateral crossing by the lower region of pons, and Nucl. ovalis (Grossmann) may have rela-tion to sense of taste.

4) It seems to be sure that the affection of medial longitudinal fasciculus has a close connection to horizontal nystagmus and the direction of it is towards affected side.

From our observations we concluded that the lesion of dorsomedial portion of lower pons may result in facial abducent paralysis and vestibular dysfunction homolaterally, hypesthe-sia on face and disturbance of taste contral-aterally.
