Abstract
Key Clinical Message Although it is rare, physicians should be familiar with the presentation of lateral medullary syndrome (LMS). Urgent neuroimaging is crucial to distinguish LMS from other causes of stroke. The majority experience significant improvement within months. Abstract Lateral medullary syndrome is a rare type of stroke resulting from a vascular event in the lateral part of the medulla oblongata. Loss of pain and temperature in the ipsilateral side of the face, and contralateral side of the body along with ipsilateral ataxia, vertigo, nystagmus, dysphagia, and hiccups are the hallmark clinical presentation. We reported a case of a 51-year-old male with a long history of smoking and newly discovered hypertension who presented complaining of vomiting, regurgitation, and hiccups for 1 month; tingling and numbness sensation in the left side of the face and the right side of the body, and unsteady gait for 2 weeks. Neurological examinations revealed left-sided ptosis and miosis, diminished sensation of the three divisions of the trigeminal nerve, deviated uvula to the right side, absent gag reflex, and intention tremors. The patient received the appropriate treatment; showed a good recovery with his symptoms, was able to walk unsteady, and was discharged after 10 days in a good condition.

Ocular contrapulsion followed by ipsipulsion in Wallenberg syndrome: The first case report in literature. Radiol Case Rep 2022; 17:4148-4151. [PMID: 36105828 PMCID: PMC9464770 DOI: 10.1016/j.radcr.2022.06.099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Accepted: 06/27/2022] [Indexed: 11/23/2022] Open
Abstract
Wallenberg syndrome is also called lateral medullary syndrome, a neurological disorder resulting from occlusion of the vertebral artery or the posterior inferior cerebellar artery. The clinical presentations are associated with a variety of indications, including vestibulocerebellar symptoms, autonomic dysfunction and ipsilateral cerebellar signs. The ipsipulsion, an abnormality of the ocular movement associated with the Wallenberg syndrome, is more specific to the lateral medullary syndrome and is characterized by a tonic deviation of the eyes in the direction of the damaged side, more prominently when the visual fixation is interrupted. A 51-year-old male patient presented with a sudden permanent rotatory dizziness, unsteady gait, numbness in the left hemibody, left palate paresis, incoordination on left side and horizontal jerk nystagmus with left fast fase. Magnetic resonance imaging showed infarction in the left medulla and cerebellar. The ocular exam revealed saccadic lateropulsion ipsilateral to lesion. In the neurologic evaluation of the patient with Wallenberg syndrome, numerous abnormalities manifestations are present, such as vestibulo-ocular reflex deficiency, saccadic abnormalities, low pursuance movements and gaze fixation, and eye alignment dysfunction. This semiologic feature had not been described in literature until now. We hypothesize that an initial vasogenic edema extending to the left medial medulla following the acute stroke could explain the early presentation with saccadic counterpulsion. After one week and regression of the edema, the finding of lateropulsion has alternated to the classic ipsipulsion related to Wallenberg syndrome. The following case report depicts a rare case of Wallenberg syndrome associated with alterations of the ocular motricity.

Abstract
BACKGROUND AND PURPOSE Medullary infarction (MI) caused by spontaneous vertebral artery dissection (sVAD) is an important type of stroke. It is important to distinguish sVAD from other causes of stroke since the treatment strategies and prognosis were different between them. In this study, we aimed to explore the clinical and radiological features of MI in patients with acute MI caused by sVAD. METHODS Patients with acute MI caused by sVAD and non-sVAD in a single tertiary hospital were enrolled from 2010 to 2020. Epidemiologic, clinical and image features were collected and analysed. MI lesions were categorised into three levels rostrocaudally and four arterial groups: anteromedial, anterolateral, lateral and posterior. RESULTS A total of 128 patients with MI were enrolled with 47 cases of sVAD and 81 cases of non-sVAD. Patients with sVAD were younger than those with non-sVAD (med 44 years old vs 58 years old). The sVAD group was less likely to have hypertension (44.68% vs 67.90%; p=0.010) and diabetes (19.15% vs 45.69%; p=0.003), but more likely to have non-sudden onset (27.66% vs 9.87%, p=0.009), minor neck injury (19.15% vs 1.23%; p=0.001) and headache (46.81% vs 7.41%; p=0.000). Vertically, sVAD became more common in caudal medulla than in rostral medulla. Horizontally, the sVAD group was more likely to have lateral MI (91.48% vs 2.96%, p=0.000). In multivariable logistic regression analysis, age, non-sudden onset and headache were independently associated with sVAD with ORs of 0.935 (95% CI 0.892 to 0.981, p=0.006), 3.507 (95% CI 1.060 to 11.599, p=0.040) and 5.426 (95% CI 1.673 to 17.599, p=0.005). CONCLUSION sVAD was not uncommon in patients with MI, especially in patients with lateral MI. Young patients with headache and non-sudden onset should remind clinician the possibility of sVAD.

Abstract
Introduction. The lateral medullary syndrome is a neurological disease caused by ischemia in the lateral part of the medulla oblongata and is the most common form of brainstem infarction. Dysphagia is a common and clinically significant symptom of this disease because it is closely associated with the risk of recurrent pneumonia, malnutrition, dehydration, and an increase in mortality and prolonged hospital treatment. Aim. This paper aims to review and analyze data on the correlation between swallowing disorders and lateral medullary syndrome. We intend to present the symptoms, diagnostic and therapeutic procedures of dysphagia in patients with this syndrome in a comprehensive way. Methodology. The following databases were used to search the literature: KoBSON-Consortium of Serbian Libraries for Unified Procurement, PubMed, Science Direct. Results. Based on the results of the reviewed studies, it was determined that patients with the lateral medullary syndrome often have swallowing disorders. They are often fed through a nasogastric tube a few months after the stroke, which significantly impairs their quality of life. To overcome swallowing disorders and create conditions for safe swallowing function, most patients need treatment for a longer period. In addition to the available screening tests, instrumental diagnostic methods provide insight into the biomechanical aspects of swallowing disorders, determine the risk of aspiration, and provide a starting point for selecting treatment strategies. Conclusion. Treatment of dysphagia depends on the mechanisms of occurrence and the predictors of recovery of swallowing function. When conducting treatment, among other things, it is very important to know the pathological mechanisms of neural connections of the medulla oblongata.

Characteristics and Prognostic Factors of Swallowing Dysfunction in Patients with Lateral Medullary Infarction. J Stroke Cerebrovasc Dis 2021; 30:106122.

Abstract
OBJECTIVES Lateral medullary infarction mainly impairs the pharyngeal phase of swallowing. We aimed to investigate the utility of the assessment tools of swallowing function in patients with lateral medullary infarction and to determine the factors that could predict the outcomes of swallowing function. MATERIALS AND METHODS 15 patients with lateral medullary infarction who were admitted to Suiseikai Kajikawa Hospital between August 1, 2016, and March 31, 2020 (age 62.7 ± 14.8 years, 5 women) were enrolled in this prospective study. The diagnosis was made using brain magnetic resonance imaging. We analyzed the factors associated with severe swallowing dysfunction, which was defined as the necessity for tube feeding on the 90th day from admission, with multiple logistic regression analysis. RESULTS Multivariate analyses identified the repetitive saliva swallowing test, modified water swallowing test, and vertical spread of stroke lesions as independent significant factors affecting severe swallowing dysfunction (p = 0.002, 0.016, and 0.011, respectively). The sub-scores of the pharyngeal phase of the Mann Assessment of Swallowing Ability were also significantly associated with severe swallowing dysfunction (p < 0.001). However, tongue pressure, severe passage pattern abnormality on videofluoroscopic examination, and vertebral artery dissection were not significantly associated with swallowing dysfunction. CONCLUSIONS Since lateral medullary infarction presents with swallowing dysfunction mainly in the pharyngeal phase, tools that can be used to evaluate the pharyngeal phase of swallowing, such as repetitive saliva swallowing test and modified water swallowing test, are moreuseful than tongue pressure measurement.

Abstract
ABSTRACT Acute embolism of the superior cerebellar artery is rarely reported. The treatment is mainly medication, decompressive craniectomy is performed when necessary, and mechanical thrombus removal is not recommended. This article describes the admission of a 69-year-old man with acute superior cerebellar artery embolization. Compared with the imaging data of the patient 2 weeks before the onset of the disease, cerebral angiography revealed that there was a mural thrombus covering the opening of the superior cerebellar artery. It is also a bold attempt for this patient to undergo mechanical thrombectomy. The patient finally recovered well from neurological symptoms. This case report details the causes of the rare mural thrombosis leading to superior cerebellar artery embolism, and also has a new understanding of arterial embolism in acute stroke.
