Wallenberg syndrome, also known as lateral medullary syndrome or Wallenberg's syndrome, is a condition that affects the nervous system. It's often caused by a stroke in the brain stem — the. This syndrome is an uncommon lesion resulting from occlusion of a vertebral artery or its branch to the anterior spinal artery; it involves the pyramid, the medial lemniscus, and, sometimes, the.
medial longitudinal fasciculus, medial lemnis-cus, lateral lemniscus, central tegmental tract, spinothalamic tract, and rubro-olivary tract. The medial longitudinal fasciculus is the main central connection for the oculomotor nerve and coordi-nates conjugate gaze. The medial lemniscus car-ries proprioceptive, vibratory, and touch-pressure sense In conjunction with history, these findings support the clinical diagnosis of medial medullary syndrome aka Dejerine syndrome.

Medial medullary syndrome (MMS) is a rare type of stroke which results due to occlusion of the anterior spinal artery or vertebral artery or its branches. In this case report we present a patient who developed MMS secondary to Takayasu arteritis (TA). TA is a chronic inflammatory arteritis primarily involving the arch of aorta and its branches, which in our patient resulted in occlusion of. Wallenberg's syndrome or lateral medullary syndrome is associated with a variety of symptoms due to involvement of lateral segment of the medulla. It is caused most commonly due to atherothrombotic vertebral artery occlusion, followed by posterior inferior cerebellar artery (PICA) and medullary arteries. Hypertension, diabetes and smoking are. Hemimedullary syndrome is a rare syndrome in which both medial and lateral medullary lesions occur together with few reported cases. 16 - 18 It is characterized by simultaneous infarction of median, paramedian lateral and dorsal areas of the medulla oblongata. 18 It can occur occasionally in associations with multiple brain stem strokes, but.

Clinical manifestations of medial medullary infarction (MMI) vary, unlike those of the classical Déjerine syndrome. 1- 4 Ipsilateral hypoglossal palsy does not occur often, and contralateral hemiparesis and lemniscal sensory loss do not always appear. In contrast, contralateral central facial palsy, not seen in the classic description, is found in a significant number of patients with MMI. Medial medullary Syndrome Medial medulla CorticospinalTract + 12th Nerve nucleus Ipsilateral tongue paralysis + contralateral hemiplegia Vascular Sensation [edit | edit source] Sensory integration is the ability of the brain to organise , interpret , and use sensory information . Examination of sensory function involves testing patient's. The medial medullary territory is supplied by penetrating arterioles from the anterior spinal artery to the caudal medulla, and anteromedial arteries from the distal vertebral artery or proximal basilar artery to the rostral medulla.3 MMIs are more commonly associated with vertebral artery occlusion, as observed in six of nine (67%) patients in. In humans, locomotion is generated in the locomotion centre in the midbrain. The premotor cortex which is responsible for the overarching control of locomotion projects to the brainstem and therefore reticulospinal tract. As a consequence, the reticulospinal tract is able to modulate control of locomotion when working with the corticospinal tract
The most common presentation of central Horner syndrome is part of the lateral medullary syndrome from infarction of the posterior-inferior cerebellar artery or of the distal vertebral artery territory (Figs. 4A and 4B). Other neurologic findings include dysphagia, ipsilateral facial analgesia, contralateral analgesia of the trunk and. Medial medullary (Dejerine) syndrome.

We report a case of Opalski syndrome that progressed to hemimedullary infarct and contralateral medial medullary infarct and suggest a possible pathologic mechanism for Opalski syndrome Medullary sponge kidney is a benign congenital disorder characterized by dilatation of collecting tubules in 1 or more renal papillae, affecting 1 or both kidneys. Medullary sponge kidney is usually a benign condition, and patients can remain asymptomatic
3. Discussion. Babinski-Nageotte syndrome is regarded as a combination of the medial and lateral medullary syndrome.  Because the arterial blood supply to the dorsolateral and medial parts of the medulla comes from different blood vessels, this syndrome is characterized by the simultaneous occurrence of lesions of both areas In this patient, the probable etiology to this syndrome was the. Overview. The lateral medullary syndrome is one of the most common clinical syndromes of brain stem caused by the decreased blood supply to the lateral medulla.It is also commonly known as Wallenberg's syndrome or posterior inferior cerebellar artery syndrome (PICA).The most common cause is thromboembolic occlusion of vertebral arteries.It was described in 1895 Medulla oblongata, the lowest part of the brain and the lowest portion of the brainstem. Neurons in the different regions of the medulla oblongata transmit motor and sensory impulses and carry out complex integrative functions, helping regulate processes such as respiration, heart rate, and digestion
Vertebrobasilar Artery Syndrome. The vertebral arteries arise from the subclavianarteries and travel into the brain along the medulla where they merge at the inferior border of the pons to form the basilar artery. The vertebral arteries supply the cerebellum (via posterior inferior cerebellar arteries) and the medulla (via the medullary arteries) World's Best PowerPoint Templates - CrystalGraphics offers more PowerPoint templates than anyone else in the world, with over 4 million to choose from.

Affected structures and resultant deficits include: • corticospinal tract medullary pyramid Lesions result in contralateral spastic hemiparesis. • medial lemniscus Extrapyramidal tracts is concerned with motor functions other than pyramidal tract. They are considered as an indirect motor pathway. Rubrospinal Tract. Reticulospinal Tract, Dividid into 2 types: A-pontine reticulospinal tract. (Medial) B-Medullary reticulospinal tract. (Lateral), Tectospinal Tract.,Vestibulospinal Tract Weber's syndrome is a neurological condition caused by an injury to the midbrain, the uppermost section of the brain stem. It's usually caused by a stroke (infarction), but in rare cases, Weber's syndrome can also be caused by a brain tumor, a traumatic injury, or infection. The midbrain is already one of the smallest regions of the brain.
Midthoracic spinal syndrome (e.g., T-4 myelopathy) may be false localizing, and apparent clinical dysfunction at this level may actually be due to impaired perfusion at higher or lower cord levels or to global ischemia.
