The authors report a woman aged 53 years with the main components of the syndrome of Opalski coexisting with signs characteristic of Wallenberg's syndrome. The lacking components of the former syndrome included Horner's syndrome, while nystagmus, diplopia without evident oculomotor nerves, paresis, disturbances of speech and deglutition belonged to the latter syndrome. The clinical pattern and the course of the disease suggested a vasogenic focus in the right submedullary region and inferolateral part of the medulla.

we report a patient with Wallenberg's syndrome caused by glioma of the lateral medulla oblongata, and review the literature for Wallenberg's syndrome associated with neoplastic disease. A 46-year-old man was admitted because of progressive dysphagia and vertigo. Neurological examination revealed atypical symptoms and signs of Wallenberg's syndrome on the right side, hypalgesia on the second and third divisions of the left trigeminal nerve, paresis of the right palate and uvula, and ataxia of the right extremities. Although CT showed no abnormality in the posterior fossa, MRI demonstrated a mass with abnormal signal intensities in the right dorsolateral portion of the medulla. Biopsy specimens showed astrocytoma (grade III). Based on the present case and a review of 10 previously reported cases of Wallenberg's syndrome caused by neoplastic disease, the clinical features of this syndrome are characterized by gradual development and steady progression of symptoms, non-classical or atypical symptomatology, numerous additional symptoms and signs depending on the site and size of tumors, and poor prognosis.

This study presents particular clinical manifestations in 7 patients with autoiMmune diseases: rheumatoid purpura with right crural nerve paresis (1 case), Stevens-Johnson syndrome with encephalomyeloradicular syndrome (1 case) and left Wallenberg syndrome (1 case), rheumatoid arthritis with right parieto-occipital syndrome (1 case) and Gowers local panatrophy (1 case), systemic lupus erythematosus with confusional state and meningeal syndrome (1 case) and left ictal hemiplegia (1 case). The importance of neurological clinical manifestations at the onset or during the evolution of the autoimmune diseases is emphasized.

The lessons of a retrospective study of 24 consecutive cases of Wallenberg syndrome observed during a 6-year span are described: the high frequency of signs and symptoms not considered typical, such as headache, diplopia, supranuclear homolateral facial paresis and homolateral brachiocrural hemiparesis; the unfavorable short term course in a high percentage of cases, and the risk of sudden respiratory arrest.

Eleven cases presenting a syndrome of the medulla oblongata are discussed with reference to the findings of clinical and angiographic investigation. The diagnosis of Wallenberg's syndrome is justified when the classic symptoms are apparent (Horner's syndrome, nystagmus, dysphonia and dysphagia, ataxia, ipsilateral sensory impairment of the face and contralateral elsewhere, and accompanying vegetative disturbances). If additional symptoms such as a facial or extra-ocular muscle paresis, especially hemiparesis, exist, another, more lateral or medial, syndrome of the oblongata should be considered. Angiographic findings vary considerably, ranging from a normal vertebral artery or posterior inferior cerebellar artery (PICA) to an occlusion of these arteries (in three and two of the 11 cases respectively). Modification are often seen in the anterior inferior cerebellar artery (AICA). A kind of complementary supply in the PICA-AICA region must occasionally exist. Localised processes affecting these vessels rather than diffuse multifocal vascular processes would lead to Wallenberg's syndrome. It is difficult to conclude from the clinical picture where a possible responsible vascular narrowing or obliteration may lie, even if pareses of the limb were present.

Vestibular dysfunction is a significant differential diagnosis in patients who have unexpected falls without: loss of consciousness, paresis, sensory loss, or cerebellar deficit. Either peripheral or central vestibular disorders cause postural instability with preferred directions of falling, some of which can be attributed to either the particular plane of the affected semicircular canal or a central pathway mediating the 3-dimensional vestibulo-ocular reflex in yaw, pitch, and roll. Ipsiversive falls occur in vestibular neuritis or in Wallenberg's syndrome--where they are known as lateropulsion. Contraversive falls are typical for the otolith Tullio phenomenon, vestibular epilepsy, and thalamic astasia. Predominant fore-aft instability is observed in bilateral vestibulopathy, benign paroxysmal positioning vertigo, as well as in downbeat or upbeat nystagmus syndrome. Falls can be diagonally forward (or backward) and toward or away from the side of the lesion, depending on the site of the lesion (the ocular tilt reaction is ipsiversive in medullary lesions, but contraversive in mesencephalic lesions) and on whether vestibular structures are excited or inhibited.

Eye movement research during the last year is discussed. The review covers the fields of: memory-guided saccades in supplementary motor area lesions, and the vertical saccadic system; cerebral hemispheric localization of smooth pursuit asymmetry; oculomotor disturbances in Wallenberg's syndrome; locomotory gaze instability in vestibular dysfunction; smooth pursuit disorders in vermal infarct; physiologic end-point and rebound nystagmus and the results of surgical and optical treatment of manifest latent nystagmus; clinical/magnetic resonance imaging correlations in abnormalities of horizontal gaze; mesencephalic cholinergic nuclei in progressive supranuclear palsy; as well as mesencephalic damage in diabetic third nerve palsy, divisional oculomotor nerve paresis; and new hypotheses on eye muscle susceptibility in myasthenia gravis.

Palatopharyngeal paresis has never been reported to be contralateral in the lateral medullary infarction (LMI). A 65-year-old lady with acute dorsolateral infarction in the left medulla presented mild hoarseness, mild dysphagia, mild gait ataxia along with marked hypalgesia and thermal anesthesia on the right limbs. To our surprise, palatal weakness was on the right side, instead of being on the left side as expected in typical Wallenberg syndrome. The palatal paresis was noted during voluntary phonation but turned into normal movement while gag reflex was induced. An involvement of corticobulbar fibers before synapsing into the ipsilateral caudal medulla or a selective involvement of the peri-ambigual reticular formation and/or its post-synaptic connection fiber destined to the contralateral swallowing center presumably underlies such a rare contralateral palatal paresis.

A 56-year-old man presented with sudden-onset oropharyngeal dysphagia and vomiting of central etiology. Neurological evaluation showed uvula deviation to the left, paresis of the mid-right portion of the soft palate, lateralization of gaze to the right side, and dysphonia. Magnetic resonance imaging (MRI) showed an infarction in the left lateral medullary region, therefore the diagnosis of Wallenberg's syndrome was established. The neurological issues along with the dysphagia gradually improved and the patient was discharged.

A 68-year-old man was referred to our hospital for a dysphagia evolving for 10 days. Clinical examination had found neurological signs as contralateral Horner's syndrome, ipsilateral palatal paresis, gait ataxia and hoarseness. Video-fluoroscopy showed a lack of passage of contrast medium to the distal esophagus. Esogastroduodenoscopy was normal. The cranial MRI had shown an acute ischemic stroke in the left lateral medullar region and the diagnosis of Wallenberg syndrome (WS) was established. WS remains an unknown cause of dysphagia in the clinical practice of the gastroenterologist.
