RESUMEN
Objective To investigate the clinical and imaging features of adult brain stroke with Wallerian degeneration.Methods The clinical and imaging data of 3 adult patients with post-stroke Wallerian degeneration were retrospectively analyzed,and the literature was reviewed.Results All the three patients had a history of stroke,and the disease recurred several months later.Head MRI examination showed abnormal signals in the pontine,which were consistent with the disfigurement of the pyramidal tract of the primary lesion.Combined with the clinical symptoms of the patients,they were diagnosed as post-stroke Wallerian degeneration.Conclusions Patients with Wallerian degeneration after stroke may show changes in clinical symptoms,and are easily misdiagnosed as cerebral infarction,often with poor prognosis.Clinical awareness of this disease should be improved to avoid misdiagnosis,so as to improve the prognosis of patients and improve the quality of life.
RESUMEN
Objective The purpose of this paper is to further understand the clinical manifestations of impaired vestibular function in the sixteen-and-a-half syndrome and the different forms of nystagmus caused by pontine lesions,so as to improve the clinical diagnosis and treatment ability.Methods Combined with the medical history,clinical symptoms,signs and auxiliary examination in the case report,the eye movement characteristics and related nerve pathways of the sixteen-and-a-half syndromes were comprehensively analyzed to locate the pons lesions.Results In this patient,the Ⅷ cranial nerve(vestibulo-cochlear)simply involved the left vestibule,and there were clinical evidences of spontaneous nystagmus with left torsional upbeat and reduced function of the left saccule pathway.The lesions at the pontine showed vertical gaze-evoked nystagmus.Conclusions In the sixteen-and-a-half syndrome,the vestibular cochlear nerve is involved and may involve only the vestibular part without hearing impairment.The lesion of pons may result in sixteen and a half syndromes,and may also result in vertical gaze-evoked nystagmus.
RESUMEN
Objective To observe the correlations of pontine biological indicators on fetal brain median sagittal MRI with gestational week.Methods Data of head MRI of 226 normal fetuses without obvious abnormalities of central nervous system(normal group)and 17 fetuses with abnormalities(abnormal group)at gestational age of 23 to 38 weeks were retrospectively analyzed.Pontine biological indicators based on median sagittal MRI were obtained,including pons anteroposterior diameter(PAD),total pons area(TPA),pontine basal anteroposterior length(AP),pontine basal cranio-caudal length(CC),basis pontis area(BPA)and pontine angle of midbrain(MAP).According to the gestational week,the fetuses of normal group were divided into 8 subgroups.The distributing ranges of pontine biological indicators at different gestational weeks were analyzed,and the correlations of pontine biological indicators with gestational week in normal group were explored,and the developmental status of fetal pons in abnormal group were assessed.Results In normal group,PAD,TPA,AP,CC and BPA all showed linear positive correlation(r=0.887,0.914,0.787,0.866,0.865,all P<0.001),while MAP was not significantly correlated with gestational week(P>0.05).Among 17 fetuses in abnormal group,abnormal PAD or TPA was found each in 8 fetuses,abnormal AP was observed in 14,abnormal CC was noticed in 3 and abnormal BPA was found in 11 fetuses.Conclusion Fetal pontine biological indicators such as PAD,TPA,AP,CC and BPA on median sagittal MRI were positively correlated with gestational week,hence being able to be used for evaluating fetal pontine development.
RESUMEN
In a country like India, oral metronidazole is the commonly prescribed drug of choice for entities such as amebiasis and visceral abscesses. Oral such cases, it is usually well tolerated and safe but can cause serious neurological adverse events. Peripheral neuropathy commonly encounters in practice but central nervous system toxicity is also well documented as it crosses the blood–brain barrier easily. Neurological toxicity of metronidazole may be due to prolonged administration, high doses, or high cumulative doses. Magnetic resonance imaging (MRI) of brain is the modality of choice to evaluate brain involvement. In the brain, the splenium of the corpus callosum, dentate nucleus of the cerebellum, and posterior pons involvement are commonly seen and diagnostic. Here, we have an interesting case report of a patient who was on oral metronidazole treatment for his large liver abscess, presenting with a complaint of neurological symptoms of unsteady gait, vertigo, dysdiadochokinesia, and difficulty in speech. Moreover, thus suspected as metronidazole drug toxicity and further investigated for the same, and MRI typically shows cerebellar and posterior corpus callosal involvement
RESUMEN
Objective:To investigate the changes in gray matter volume (GMV) and abnormalities in structural covariant network (SCN) patterns in patients with chronic pontine infarction (PI).Methods:Patients with unilateral chronic PI (case group) with the first onset admitted to the First Affiliated Hospital of Zhengzhou University and Tianjin Medical University General Hospital from October 2014 to June 2021 were prospectively included. At the same time, healthy subjects matched with age, gender and education years (normal control group) were included. High-resolution three-dimensional T 1 structural MRI images and behavioral scores of the subjects were collected. The voxel-based morphometry and two-sample t test were used to explore the differences in GMV between the groups. Using GMV differential brain regions as seed points, SCN was constructed to explore the abnormality of structural covariant patterns in patients with PI. Spearman rank correlation analysis was used to analyze the correlation between GMV in differential brain regions and behavioral scores. Results:A total of 60 patients with PI were enrolled, including 33 left PI and 27 right PI, while 34 healthy controls were also enrolled. Compared with the normal control group, the GMV in bilateral posterior cerebellar lobe decreased significantly in the left PI group, and the GMV in left anterior and posterior cerebellar lobes and the right posterior cerebellar lobe decreased significantly in the right PI group (Gaussian random field correction with voxel level P<0.001 and cluster level P<0.05, cluster voxel >20), and there was a significant correlation between GMV values in the left anterior and posterior cerebellar lobes and the right posterior cerebellar lobe and the motor function score ( P<0.05). In addition, compared with the normal control group, the right PI group had broader covariate brain regions and a significant increase in the number of structural connections between covariate brain regions (family-wise error correction with voxel level P<0.05, cluster voxel >20). Conclusions:The GMV in bilateral posterior cerebellar lobe decreases significantly in patients with chronic PI, and were secondary to broader covariate brain regions and structural connections. This may be the neural mechanism of impaired behavioral function in patients with PI.
RESUMEN
Isolated pontine infarction (IPI) is the main type of acute brainstem infarction. Due to the application of high-resolution MRI, the research on the etiology of IPI has gradually increased in recent years. This article reviews the latest research progress on the characteristics of basilar artery plaques and disease progression mechanisms of IPI, aiming to provide reference for the etiology research of IPI.
RESUMEN
Background:liver is a soft, friable and largest gland in the body, occupying the upper part of the abdominal cavity just beneath the right diaphragm. The greater part of it is situated under cover of the ribs, extending to the left to reach the left diaphragm. Objective: to determine gross anatomical variations of liver and their clinical and surgical implications. To study variations in lobes, fissures and accessory lobes were observed. Material And Methods:a total of 50 formalin-fixed adult human livers, irrespective of the sex, were studied over a period of three years from Dr M K shah medical college. These livers were specifically observed for any variant or anomalous surface morphology. Result:out of 50 specimens, 16 were considered normal without any ac-accessory fissures, lobes, or presence of a pones hepatis. 34 livers had one or more morphological variations.14 liver has accessory fissure, 10 liver are present with riedel’s lobe present in liver, 10 liver are present with pons hepatic. Conclusion:liver being the largest abdominal organ, the knowledge of its normal and variant morphology is essential for the clinicians. In general, accessory hepatic fissures/sulci are potential sources of diagnostic errors during imaging. On ultrasound or computerized tomography, any collection of fluid in these fissures may be mistaken for a liver cyst, intrahepatic hematoma, or liver abscess, which would require further radiologic workup.
RESUMEN
Objective:To investigate the clinical and imaging features of bilateral Wallerian degeneration of the middle cerebellar peduncles secondary to isolated pontine infarction.Methods:Patients diagnosed as bilateral Wallerian degeneration of cerebellar middle peduncle after isolated pontine infarction admitted to the Second Affiliated Hospital of Zhengzhou University from June 2017 to December 2021 were retrospectively included. Patients with bilateral Wallerian degeneration of cerebellar middle peduncle after isolated pontine infarction reported between January 2001 and December 2021 were collected by searching Chinese and English databases, and their clinical and imaging characteristics were summarized.Results:A total of 48 patients with bilateral Wallerian degeneration of cerebellar middle peduncle after isolated pontine infarction were included, including 14 patients admitted to the Second Affiliated Hospital of Zhengzhou University, and 34 patients collected by searching the Chinese and English databases. Thirty-three patients were males (68.75%) and 15 were females (31.25%). Their age was 65.8±10.7 years old (range, 37-88 years). Most patients had vascular risk factors, and hypertension was the most common. Dysarthria and limb weakness were the main clinical symptoms at admission. The infarct sites of all 48 patients were located in the blood supply area of paramedian pontine arteries, of which 37 (77.08%) were unilateral (18 on the left and 19 on the right), 6 (12.50%) were bilateral sides, and 5 (10.42%) had incomplete data. When Wallerian degeneration was diagnosed, 8 patients (16.67%) had dizziness or ataxia, 6 (12.50%) had aggravated original symptoms, and the remaining 34 (70.83%) had no new symptoms or aggravated original symptoms. All patients showed symmetrical abnormal signals in bilateral middle cerebellar peduncles, with obvious hyperintensity on T 2 or diffusion-weighted imaging (DWI). One patient showed T 2 hyperintensity in bilateral middle cerebellar peduncle on the next day after the onset of the infarction, which was the earliest case to find secondary Wallerian degeneration after isolated pontine infarction. Conclusions:Wallerian degeneration should be considered when symmetrical lesions of bilateral middle cerebellar peduncles occur after isolated pontine infarction. Wallerian degeneration may occur early after isolated pontine infarction. Most cases have no new symptoms or aggravated original symptoms. Conventional MRI can identify it early.
RESUMEN
Objective:To investigate the efficacy and safety of sequential treatment with tirofiban and argatroban in acute isolated pontine infarction (AIPI) caused by branch atheromatous disease (BAD).Methods:Consecutive patients with AIPI caused by BAD within 48 h of onset and admitted to Zhengzhou Central Hospital from April 2021 to April 2022 were enrolled retrospectively. The patients were divided into sequential treatment group and tirofiban group according to their therapeutic modalities. In the tirofiban group, tirofiban was pumped intravenously within 48 h after admission, and dual antiplatelet therapy with aspirin and clopidogrel was added 4 h before tirofiban was discontinued. On the basis of tirofiban treatment, the sequential treatment group was followed by argatroban for 5 days when tirofiban is discontinued. The main outcome measure was the modified Rankin Scale (mRS) score at 3 months after the onset . A score of <2 was defined as a good outcome. The secondary outcome measure was all the adverse events during the treatment and follow-up. Multivariate logistic regression analysis was used to determine the independent factors of the outcomes. Results:A total of 64 patients with AIPI caused by BAD were enrolled, including 32 in the sequential treatment group and 32 in the tirofiban group. There was no statistical difference in baseline data between the two groups, but the rate of good outcomes at 3 months after onset in the sequential treatment group was significantly higher than that in the tirofiban group (78.1% vs. 50.0%; χ2=5.497, P=0.019). Multivariate logistic regression analysis showed that after adjusting for low-density lipoprotein cholesterol, the higher baseline National Institutes of Health Stroke Scale score was independently associated with the poor outcomes (odds ratio 2.067, 95% confidence interval 1.343-3.182; P=0.001), while the sequential treatment was independently associated with the good outcomes (odds ratio 0.248, 95% confidence interval 0.064-0.957; P=0.043). Conclusion:Early application of sequential treatment with tirofiban and argatroban in AIPI caused by BAD may effectively improve the outcomes of patients, and the safety is good.
RESUMEN
Internuclear ophthalmoplegia mainly affects the horizontal movement disorder of the eyeball. "One and a half syndrome" is characterized by a combination of one eyeball on the affected side cannot be adducted and abducted, and the other eyeball cannot be adducted, but can be abducted accompanied by horizontal nystagmus due to the lesion of tegmental pontine. At present, articles have successively reported "eight and a half syndromes""nine syndromes""thirteen and a half syndromes" and so on. The rapid identification of "one and a half syndrome" spectrum is helpful for clinicians to make right positioning and clinical decision-making. A case of bilateral peripheral facial paralysis with bilaterally horizontal gaze palsy caused by pontine dorsal tegmental lesions is now reported, so as to improve the understanding of the anatomical location and heterogeneity of pontine lesion.
RESUMEN
Resumen La coartación de aorta es una cardiopatía congénita con altas tasas de morbilidad y mortalidad, que usualmente es subdiagnosticada a pesar de la disponibilidad de herramientas diagnósticas. El grado de severidad de las manifestaciones clínicas de la coartación de aorta va a depender del grado de obstrucción, así como de la presencia de defectos cardiacos y lesiones extracardíacas asociados. En la población pediátrica la modalidad terapéutica mayormente utilizada es la reparación quirúrgica; mientras que la angioplastia con balón y la colocación de una endoprótesis son menos utilizadas en esta población, ya que asocian mayor riesgo de reestenosis con la consecuente reintervención, estas técnicas son principalmente utilizadas en pacientes mayores. A pesar del éxito en la reparación de la coartación de aorta, los pacientes deben continuar un seguimiento estrecho a largo plazo, que incluye mediciones de la presión arterial de manera periódica, así como estudios por imagen de la estructura cardíaca, debido a la aparición tardía de complicaciones cardiovasculares asociadas.
Abstract Coarctation of the aorta is a congenital heart disease with high rates of morbidity and mortality, which is usually underdiagnosed despite the availability of diagnostic tests. The degree of severity of the clinical manifestations of coarctation of the aorta will depend on the level of obstruction, as well as the presence of cardiac defects and associated extracardiac lesions. In the pediatric population the most used therapeutic modality is surgical correction; while balloon angioplasty and stent placement are less used in this population, since they are associated with a greater risk of restenosis with the subsequent reintervention; these techniques are mostly used in older patients. Despite the success in the repair of coarctation of the aorta, patients should continue a close long-term follow-up, which includes periodic blood pressure measurements, as well as imaging studies that assess the cardiac structure, due to the late onset of associated cardiovascular complications.

Resumen La neuralgia del trigémino (NT) es una enfermedad cuya prevalencia es alta y corresponde a un porcentaje importante de neuralgias faciales; en donde las personas más afectadas son mayores de 50 años. Su manifestación clínica suele ser de cuadros de dolor facial severo y recurrentes, unilateral; en la distribución de una o más divisiones del nervio trigémino y no se explica con otro diagnóstico. El diagnóstico se basa en el cuadro clínico y usualmente no se encuentra déficit sensorial, sin embargo, si está presente se deben hacer neuroimágenes para descartar otras causas. En primera instancia está el manejo farmacológico. La carbamazepina se ha establecido como efectivo, llegando a producir un alivio del dolor dentro de las 24 horas. Cuando la farmacoterapia falla, se opta por la cirugía que se divide generalmente en dos: técnicas que destruyen la porción sensitiva del nervio; y la descompresión microvascular (DMV), que es la que tiene mejores resultados.
Abstract Trigeminal neuralgia is a disease whose prevalence is high and corresponds to a significant percentage of facial neuralgia; where the most affected people are over 50 years old. The clinical picture is usually of episodes of severe and recurring facial pain, unilateral; in the distribution of one or more divisions of the trigeminal nerve and this is not explained with another diagnosis. Diagnosis is based on the clinic and usually no sensory deficit is found, however, if present, neuroimaging should be done to rule out other causes. In the first instance is the pharmacological management. Carbamazepine has been established as effective, leading to pain relief within 24 hours. When pharmacological therapy fails, surgery is generally divided into two: techniques that destroy the sensitive portion of the nerve and microvascular decompression, which has the best results.

@#Objective To investigate the characteristics of high resolution vessel wall imaging (HR-VWI) imaging of unstable plaques in acute pontine infarction.Methods Data from thirty-nine patients with symptomatic acute pontine infarction and 45 patients with asymptomatic pontine infarction in the Peopl’s Hospital of Baoan District,Shenzhen from June 2016 to November 2019 was retrospectively analyzed.The distribution of BA plaques and plaque involvement were counted on HR-VWI Quadrant.Plaque surface continuity,plaque length,vascular volume (Vouter),vascular wall volume (V wall),lumen diameter in the narrowest layer of the lumen (LD MLN),maximum diameter of the outer lumen (OD MLN ),vascular area (OA MLN),vascular wall area (WA MLN),the thickest thickness (WTmax),the plaque load (PB),and lumen stenosis rate were measured.Measurement indicators were compared between the two groups.Results The plaque distribution,plaque discontinuity,WTmax,WA MLN,PB,and BA lumen stenosis rates between the two groups were statistically different (P<0.05).Conclusions BA plaques with symptomatic pontine infarction are more likely to be distributed on the side wall,the surface is more discontinuous,thicker plaque thickness,larger blood vessel area and plaque load,higher luminal stenosis rate,suggesting that it has instability Plaque characteristics.
RESUMEN
Objective To investigate the risk factors for progressive motor deficit (PMD) in patients with acute isolated pontine infarction.Methods Patients with new onset of acute isolated pontine infarction admitted to the Department of Neurology,the Second Hospital of Tianjin Medical University from January 2016 to December 2018 were enrolled retrospectively.The demography,vascular risk factors,laboratory examinations,and imaging features were compared between PMD group and non-PMD group.Multivariate logistic regression analysis was used to determine the independent risk factors for PMD.Results A total of 117 patients with acute isolated pontine infarction were enrolled,including 46 females (39.3%) and 71 males (60.7%),aged 70.62 ± 9.07 years.Twenty-six patents (22.2%) were in the PMD group and 91 (77.8%) were in the non-PMD group.The blood glucose at admission (7.28[6.68-8.27] mmol/L vs.6.66[5.64-7.87]mmol/L;Z =-2.367,P =0.018] and the proportion of hypertension (80.8% vs.57.1%;x2=4.811,P=0.028),paramedian pontine infarction (80.8% vs.45.1%;x2=10.355,P=0.001),and lower pontine infarction (46.2% vs.25.3%;x2 =4.205,P =0.040) in the PMD group was significantly higher than those in the non-PMD group.Multivariate logistic regression analysis showed that hyperglycemia at admission (odds ratio 1.444,95% confidence interval 1.048-1.988;P=0.024) and paramedian pontine infarction (odds ratio 3.266,95% confidence interval 1.061-10.055;P =0.030) were the independent risk factors for PMD in patients with acute isolated pontine infarction.Conclusion Hyperglycemia at admission and paramedian pontine infarction were the independent risk factors for PMD in patients with acute isolated pontine infarction.
RESUMEN
Objective To compare and analyze the etiology,clinical manifestations and imaging differences of bilateral pontine infarction (BPI) and unilateral pontine infarction (UPI),and investigate the possible independent risk factors for BPI.Methods Consecutive patients with pontine infarction admitted to the Department of Neurology,the First People's Hospital of Kunshan from January 2015 to December 2017 were enrolled retrospectively.They were divided into BPI group and UPI group.The risk factors,laboratory findings,National Institutes of Health Stroke Scale (NIHSS) scores,clinical manifestations,and basilar artery lesions were compared between the two groups.Multivariate logistic regression analysis was used to determine the independent risk factors for BPI relative to UPI.Results A total of 131 patients with pontine infarction were enrolled,aged 66.22 ± 12.29 years,97 patients (72.52%) were male;14 (10.69%) were BPI,and 117 (89.31%) were UPI.In terms of clinical symptoms,consciousness disorder (35.71% vs.6.83%;x2 =8.657,P =0.003),quadriplegia (50.00% vs.5.12%;x2 =30.202,P < 0.001),and dysphagia (71.42% vs.29.91%;x2 =7.804,P =0.005) in the BPI group were more common than those in the UPI group.In terms of etiological classification,vertebrobasilar large artery disease (VLAD) was more common in the BPI group (85.71% vs.27.35%;x2 =16.567,P < 0.001),while small artery disease (SAD) was more common in the UPI group (49.57% vs.7.14%;x2 =7.460,P =0.006).In addition,the baseline NIHSS scores (12.43 ±11.1 vs.3.78 ±3.98;t=2.873,P=0.013),white blood cell count ([9.21±2.81] ×109/L vs.[6.92± 2.40] ×109/L;t=3.191,P=0.002),baseline systolic blood pressure (170.57 ±31.21 mmHg vs.156.75 ±23.50 mmHg,1 mmHg =0.133 kPa;t =2.004,P =0.047),as well as the proportion of patients with severe stenosis or occlusion in basilar artery (78.57% vs.8.55%;x2 =40.49,P < 0.001) and with other site infarction (78.57 % vs.11.11%;x2 =33.652,P < 0.001) in the BPI group were significantly higher than those in the UPI group.Multivariate logistic regression analysis showed that severe basilar artery stenosis or occlusion (odds ratio [OR] 20.195,95% confidence interval [CI]2.308-176.703;P =0.007),baseline NIHSS score (OR 1.147,95% CI 1.019-1.292;P =0.023),and infarction at other sites (OR 19.483,95% CI 2.969-127.868;P =0.002) were independently associated with BPI.Conclusion Compared with UPI,patients with BPI had more severe clinical symptoms and most of them with other site infarction.Severe stenosis or occlusion of the basilar artery was an independent risk factor for BPI.
RESUMEN
Objective To investigate the correlation between serum uric acid level and short-term outcome of acute isolated pontine infarction. Methods From April 2016 to April 2018, consecutive patients with acute isolated pontine infarction admitted to the Department of Neurology, Kaifeng Central Hospital were enrolled. The baseline clinical data were collected. Fasting venous blood was collected on the day of admission or the morning of the next day for blood biochemical tests. The National Institutes of Health Stroke Scale (NIHSS) was used to assess the severity of neurological deficit. According to the modified Rankin Scale score at discharge or 14 dafter onset, the patients were divided into good outcome group (≤2) and poor outcome group ( > 2 ). Multivariate logistic regression analysis was used to determine the independent risk factors for short-term poor outcome. Results A total of 137 patients were enrolled in the study, 108 (78.8% ) had a good outcome, and 29 (21.2% ) had a poor outcome. The baseline NIHSS score (median [ interquartile range]: 2.5 [1.0-4.0] vs. 8.5 [5.5-10.0 ]; Z= 6.092, P< 0.001 ) and total cholesterol levels (4.290 ± 0.101 mmol/L vs. 4.763 ± 0.171 mmol/L; t=2.214, P=0.028] in the good outcome group were significantly lower than those in the poor outcome group, while serum uric acid level (329.769 ± 8.122μmol/L vs. 257.103 ± 14.290μmol/L; t=4.190, P<0.001) was significantly higher than that in the poor outcome group. Multivariate logistic regression analysis showed that high serum uric acid levels were independently associated with short-term good outcomes in patients with isolated pontine infarction (odds ratio [ OR] 0.377, 95% confidence interval [ CI] 0.203-0.702; P=0.002), while high NIHSS score (OR 1.762, 95% CI 1.375-2.258; P<0.001) and hypertension (OR 5. 353, 95% CI 1.333-21.502; P= 0.018 ) were independently associated with short-term poor outcomes. Conclusion High baseline serum uric acid levels are associated with short-term good outcomes in patients with acute isolated pontine infarction.
RESUMEN
Progression of acute isolated pontine infarction (IPI) is a common clinical event that positively correlates with the patients' adverse prognosis.Therefore,exploration on the relevant factors and predictors to the progression of IPI has become the current research hotspot.To date,the relevant factors that have been proposed include basilar artery branch disease,female,hypertension and blood pressure fluctuation,hyperglycemia,morphological features of the lesions (ventral surface of pons involvement,located at the lower pons,multiple axial slices affected,conglomerated beads shape),severe white matter diseases,atherosclerosis,long diameter and midline location of basilar artery,and so on.However,the interpretation on existing results has to be cautious as the definition for progressive IPI,criteria for inclusion and exclusion,and examinations are inconsistent in different studies.The investigation on relevant factors to the progression of IPI still requires standardized,large-scale prospective clinical studies.
RESUMEN
A premature infant with gestational age 36⁺⁴ weeks was admitted with respiratory distress syndrome. Surfactant and ventilation were firstly done to improve his respiration. After extubation, weak, high-pitched cry and asymmetric face with micrognathia and hypertelorism were detected. Therefore, cytogenetic analysis was performed, and his karyotype was 46, XY, del(5) (p14p15.33). Pontine hypoplasia was detected on cranial magnetic resonance imaging (MRI). Therefore, karyotyping and cranial MRI should be performed in case of preterm infants with suspicion of Cri-du-chat syndrome (CdCS).

RESUMEN El Síndrome de Locked-In también conocido como Síndrome de Enclaustramiento, de Deseferentización o de Encerramiento, se definió por primera vez en 1966 por Plum y Posner. Las causas pueden agruparse en vasculares y no vasculares, siendo las primeras las más frecuentes. Clínicamente este síndrome se caracteriza porque la conciencia y el estado de vigila están conservados, pero existe cuadriplejía, anartria, disfagia y dificultad para coordinar la mecánica ventilatoria, representando las complicaciones pulmonares la principal causa de muerte. En la mayoría de los casos, el paciente conserva la movilidad ocular vertical, por tanto, el único método de comunicación es por medio de parpadeo ocular y movimientos verticales oculares. A continuación, se hace la presentación de un caso y revisión de la literatura con los aspectos fisiopatológicos, clínicos, diagnósticos y terapéuticos más relevantes.
ABSTRACT Locked-In Syndrome, also known as Enclaustration, Deseferentization, or Enclosure Syndrome, was first defined in 1966 by Plum and Posner. Causes can be grouped into vascular and non-vascular, the former being the most frequent. Clinically this syndrome is characterized by consciousness and the state of watch conserved, but there is quadriplegia, anartria, dysphagia and difficulty to coordinate the ventilatory mechanics, representing pulmonary complications the main cause of death. In most cases, the patient retains vertical eye mobility, so the only method of communication is through eye blinking and vertical eye movements. Next, a case presentation and review of the literature with the most relevant pathophysiological, clinical, diagnostic and therapeutic aspects is done.
