54. Wallenberg syndrome

  1. Lateral medullary syndrome or Wallenberg syndrome is caused by occlusion of the arteries that supply lateral medulla oblongata. (T/F?)
  2. It is usually caused by occlusion of posterior inferior cerebellar artery, therefor the name PICA-syndrome. (T/F?)
  3. The posterior inferior cerebellar artery is a branch of the basilar artery and supplies lateral parts of the medulla oblongata and parts of the  cerebellum with arterial blood. (T/F?)
  4. The syndrome is characterized by “crossed neurological signs”, ipsilateral sensory deficits of the face and contralateral sensory deficits of the trunk and the limbs. (T/F?)
  5. Other signs and symptoms include vomiting, vertigo, hoarseness, dysphonia, dysphagia, decreased gag reflex, contralateral ataxia and ipsilateral Horner’s syndrome.(T/F?)
  6. Lateral pontine syndrome is a neurological syndrome caused by occlusion of the anterior inferior cerebellar artery (AICA) and is characterized by crossed neurological signs and symptoms but also by ipsilateral deafness and facial paresis, in difference to the PICA-syndrome. (T/F?)
