ABSTRACT
This syndrome is produced by an inferior pontine injury and includes the pontine and reticular formation paramedia (PPRF) as well as the longitudinal medial fasciculus (LM) of the same side. This suffering can be originated mainly by: infarction of brainstem, multiple sclerosis and pontine hemorrhage, also cases of tuberculomas and tumors have been reported. Among the main symptoms are the ophthalmologic ones: diplopia, osciloscopy or blurred vision. We present the case of a female 40 years old, patient with five-years of arterial hypertension. Current features: intense, sudden and generalized migraine, dizziness, vertigo, vomit, paresthesias of left side of the hemibody march with difficulty. In CT scan image march with we appreciate hyperdense zone at level of the pons, compatible with hemorrhage. In the hypertensive pontine hemorrhage, it clinically appears: comma, quadriplegia, small reactive pupils and absence of ocular movements. This type of hemorrhage normally leads to the patient’s death; nevertheless, in this case the improvement is correlated to the size of the hemorrhage. It is possible to establish a precise diagnosis with the CT scan and magnetic resonance and so to improve the prognosis.
