Gasperini syndrome (GS) is a rare alternating brainstem syndrome resulting from a lesion in the caudal pontine tegmentum. The rapid rise in sodium concentration is accompanied by the movement of small molecules and pulls water from brain cells. Foville syndrome (inferior medial pontine syndrome) is due to an infarct of the pons involving the corticospinal tract, medial lemniscus, medial longitudinal fasciculus, paramedian reticular formation, and nuclei of the abducens and facial nerves ( Figs 13, 14 ). . Pontine strokes can be classified as either ischemic or hemorrhagic. - Other fibers project to the pontine paramedian reticular formation (PRRF) and then via the medial longitudinal fasciculus (MLF) to control extraocular muscles for upward gaze Which clinical concern affects the Corticotectal Tract and Tectospinal Tract?

The relative infrequency of MMS is surprising given the prevalence of stroke in other perforator artery territories as these vessels are more susceptible to small vessel disease. These special visceral efferent fibers are autonomic parasympathetic fibers that originate from a group of neuron cell bodies called the Edinger-Westphal nucleus located in the midbrain. Paramedial pontine reticular formation.

A stroke in the pons region of the brain can cause serious symptoms. For example, the prognosis for a unilateral pontine stroke (when only one side of the pons is affected) tends to be good. In addition, absence of the middle cerebellar peduncles was noted, a finding that, to our knowledge, has never been reported before in the literature. medial medullary strokes are the rarest, making up fewer than 1% of reported posterior circulation cases. It is characterised by contralateral hemiplegia/hemiparesis as well as hemisensory loss with ipsilateral hypoglossal palsy (ipsilateral tongue weakness and atrophy) from involvement of CN XII nucleus 1,2.Other manifestations such as vertigo, nausea, or contralateral limb ataxia are also reported 1,2. Brain ischemia is a condition in which there is insufficient bloodflow to the brain to meet metabolic demand. It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage.. Figure 2. On the other hand, bilateral and caudal (lower) pontine infarctions tend to have a worse prognosis. These may include problems with balance and coordination, double vision, loss of sensation, and weakness in half the body.
