Portable Thermographic Screening for Detection of Acute

Sweden Liver Week 2020

It is usually secondary to the vertebral artery and posterior inferior cerebellar artery occlusion due to atherothrombosis or embolism, and also due to a spontaneous dissection of the vertebral arteries 1-3 . MRI features are most consistent with a lateral medullary syndrome (LMS) or Wallenberg syndrome which is considered as a clinical syndrome secondary to an acute ischemic infarct involving the lateral medulla oblongata. Most commonly due to an occlusion of the intracranial portion of the vertebral artery followed by PICA and its branches. Hypertension, smoking, and diabetes mellitus are The commonest risk factors (as in this case). MRI features are most consistent with a lateral medullary syndrome (LMS) or Wallenberg syndrome which is considered as a clinical syndrome secondary to an acute ischemic infarct involving the lateral medulla oblongata. Most commonly due to an occlusion of the intracranial portion of the vertebral artery followed by PICA and its branches.

The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery. Lateral medullary syndrome is also called Wallenberg's syndrome, posterior inferior cerebellar artery syndrome and vertebral artery syndrome.

Most commonly due to an occlusion of the intracranial portion of the vertebral artery followed by PICA and its branches. Material and Methods: Thirteen patients with Wallenberg’s lateral medullary syndrome were examined with conventional and echoplanar diffusion-weighted magnetic resonance (MR) imaging in a 1.5 T magnetic resonance unit. MR examinations were obtained in the acute or subacute stage of clinical syndrome, and diffusion-weighted patients with Wallenberg's lateral medullary syndrome and to compare MRI with CT. Subjects and Methods From September 1984 through o Februarf 1985, y four hospitalized patients with Wallenberg's lateral medullary syndrome were evaluate at thde University of Iowa Hospitals.

Vertebral artery: Distal branches; Vertebral artery: Superior lateral medullary artery; Posterior inferior cerebellar artery: Less common than vertebral The lateral medullary syndrome, also known as Wallenberg's syndrome, is the prototype lesion involving the nuclei of cranial nerves IX and X. The syndrome results from infarction of the medulla by vertebral artery thrombosis or dissection that may also produce occlusion of the opening to the posterior inferior cerebellar artery. 33 Wallenberg’s syndrome (WS) is well defined clinically, and the lateral medullary infarction (LMI) is the most frequent cause, among others. The WS and LMI are easily diagnosed on the basis of the specific neurological findings, but pathological verification may usually be lacking because the LMI is rarely fatal. Listen. Wallenberg syndrome is a condition that affects the nervous system. Signs and symptoms may include swallowing difficulties, dizziness, hoarseness, nausea and vomiting, nystagmus, and problems with balance.

Vascular. Vertebral artery: Distal branches; Vertebral artery: Superior lateral medullary artery; Posterior inferior cerebellar artery: Less common than vertebral It is characterized 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. SUMMARY Four patient a clinicas witl diagnosih of Wallenberg's s lateral medullary syndrome were studied with both Magnetic Resonance Imaging (MRI) and cranial Computed Tomography (CT). Using transverse images and both T(and T2 — weighted sequences, MRI demonstrated a medullary infarction not seen on CT in all four cases. Material and Methods: Thirteen patients with Wallenberg’s lateral medullary syndrome were examined with conventional and echoplanar diffusion-weighted magnetic resonance (MR) imaging in a 1.5 T magnetic resonance unit.

Clinical presentation Each brainstem stroke syndrome has a characteristic clinical picture according to the involved area, however, generally, there is ipsilateral cranial nerve palsy and contralateral hemiplegia/hemiparesis and/or hemisensory loss 1-5 .
