Clinical presentation
- ipsilateral facial and contralateral body hemiplegia due to pyramidal tract involvement
- isotropism and diplopia that is worsened while the patient looks toward the lesion
- ipsilateral facial paresis and loss of corneal reflex

Lesions in ventral aspect of the caudal pons involving the fibers of the cranial nerves VI and VII as well as corticospinal tract .
Etiology
Causes vary by age :
- young
- tumor
- demyelination (e.g. MS)
- viral infection (e.g. rhombencephalitis)
- older
- vascular
Radiographic features
Lesions are in ventral aspect of caudal pons with imaging characteristics depend on underlying cause .
