Trombosis de seno venoso asociada con infección por SARS-CoV-2 / Cerebral venous thrombosis associated with SARS-Cov-2 infection

RESUMEN INTRODUCCION: La trombosis del seno venoso se considera una de las causas más infrecuentes de enfermedad cerebrovascular (ECV), prevalente en la edad joven. Suele tener un inicio insidioso, lo cual dificulta su diagnóstico y el inicio oportuno del tratamiento, y se encuentra asociada con múltiples factores de riesgo, incluyendo estados de hipercoagulabilidad, como en aquellos pacientes que cursan con infección por SARS-CoV-2. REPORTE DE CASO: Se presentan dos casos clínicos de pacientes con alteraciones neurológicas, diplopia y estatus epiléptico, en quienes se documentó por medio de la sintomatologia y de estudios imagenológicos, trombosis venosas extensas de localización infrecuente, se descartaron las principales etiologías asociadas, y el único nexo asociado fue la infección por SARS-CoV-2. Ambos pacientes recibieron tratamiento con anticoagulación parenteral, al que respondieron de forma exitosa, por lo cual se logró el alta posteriormente con anticoagulación oral. DISCUSIÓN: Es imprescindible el conocimiento de esta enfermedad, asociada con una alta sospecha diagnóstica, dadas sus manifestaciones clínicas variadas y su asociación cada vez más frecuente con infección por covid-19.

ABSTRACT INTRODUCTION: Venous sinus thrombosis is considered one of the most infrequent causes of cerebrovascular disease (CVD), prevalent in young people. It usually has an insidious onset which difficult its diagnosis and timely initiation of treatment and is associated with multiple risk factors including hypercoagulable states, as in those patients with SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) infection. CASE REPORT: The following are 2 clinical cases of patients with neurological alterations, diplopia, and status epilepticus, in whom extensive venous thrombosis of infrequent location was documented through symptomatology and imaging studies, ruling out the main associated etiologies, with the only associated nexus: SARS-CoV-2 infection. Both patients received treatment with parenteral anticoagulation, responding successfully and were subsequently discharged with oral anticoagulation. DISCUSSION: It is essential to be aware of this disease associated with a high diagnostic suspicion given its varied clinical manifestations and its increasingly frequent association with COVID-19 infection.

Diagnóstico neonatal temprano y asintomático de una trombosis cerebral de senos venosos en contexto de displasia septo-óptica / Early diagnosis of asymptomatic cerebral sinovenous thrombosis associated with a septo-optic dysplasia in a newborn

RESUMEN La displasia septo-óptica (DSO) es una entidad que incluye hipoplasia de nervios ópticos, disgenesia de la línea media cerebral y disfunción hipotálamo-hipofisaria. Entre las teorías sobre su patogenia es de resaltar una posible disrupción vascular que altera el desarrollo de las estructuras involucradas. Dado que la (DSO) es una patología infrecuente, se presenta el caso de un recién nacido que desde sus controles prenatales presentó alteraciones anatómicas cerebrales en línea media. Posteriormente al nacimiento se confirmaron las siguientes: ausencia de septum pellucidum, dilatación ventricular supratentorial con sospecha de estenosis acueductal y disgenesia del cuerpo calloso, además de una trombosis de seno venoso. Se resalta la importancia de mostrar la relación de estas dos patologías puesto que solamente encontramos otro caso reportado en la literatura. Igualmente, se destacan herramientas del manejo de trombosis cerebral neonatal. Por último, se resalta la utilidad de los controles prenatales como guía del enfoque rápido para el diagnóstico en este paciente.

SUMMARY The septo-optic dysplasia (SOD) is characterized by a classic triad: optic nerve hypoplasia, dysgenesis of the cerebral midline and hypothalamus-pituitary axis dysfunction, in association, sometimes, with abnormalities in the cerebral cortex. In this article, we report a case of SOD diagnosed in the first days after birth of a patient, in which we incidentally documented a cerebral sinovenous thrombosis in the prenatal check-up exams. In here we try to highlight that the combination of both pathologies is less prevalent, finding in the literature just one case reported. In the other hand, to show the importance of adequate prenatal controls to guide the diagnosis and the management of Neonatal cerebral sinovenous thrombosis.

Trombosis venosa cerebral / Cerebral venous thrombosis

En la actualidad la trombosis venosa cerebral (TVC) se considera un reto diagnóstico y terapéutico, debido a la alta variabilidad de presentación y a la falta de un consenso terapéutico claro. Representa 0,5 por ciento de los ictus y afecta con mayor frecuencia a sujetos jóvenes con factores de riesgo congénitos o adquiridos. Tiene manifestaciones clínicas variables que unidas a un estudio de neuroimagen adecuado, permiten realizar el diagnóstico. Se presenta un caso con el objetivo de describir la evolución clínico-radiológica de una paciente puérpera adolescente, con trombosis venosa cerebral que además tuvo un angioma venoso cerebral interauricular, que a los 21 días del puerperio presenta cefalea de moderada intensidad en región occipital y posteriormente hemiparesia derecha, con recuperación del defecto en 42 h. Se diagnóstica por Angio-TAC trombosis de seno recto, venas de galeno y venas cerebrales internas con evolución favorable luego de tratamiento anticoagulante(AU)

Cerebral venous thrombosis (CVT) is currently considered a diagnostic and therapeutic challenge, due to the high variability of presentation and the lack of a clear therapeutic consensus. It represents 0.5 percent of strokes and most frequently affects young subjects with congenital or acquired risk factors. The variable clinical manifestations, together with an adequate neuroimaging study, allow diagnosis. We report this case aiming to describe the clinical-radiological evolution of a postpartum adolescent patient with cerebral venous thrombosis who also had an interatrial cerebral venous angioma. She had moderate headache in the occipital region and, later, in right hemiparesis, 21 days after the puerperium. the defect was solved in 42 h. Thrombosis of the right sinus, veins of galen and internal cerebral veins was diagnosed by CT angiography. Favorable evolution was achieved after anticoagulant treatment(AU)

Isolated cortical venous thrombosis: analysis of three cases and literature review / 中华神经科杂志

Objective@#Isolated cortical venous thrombosis (ICoVT) has a low incidence and is easily to be misdiagnosed. The clinical characteristics, diagnosis and treatment of three cases of ICoVT were analyzed in order to improve the level of diagnosis and treatment.@*Methods@#The clinical manifestations, examination, imaging and pathological features of three patients with ICoVT admitted to our hospital were retrospectively analyzed.@*Results@#All the three patients had acute onset. The main symptoms were headache, seizures, numbness of one limb and mental disorders. Intracranial pressure was normal. Brain magnetic resonance imaging (MRI) showed abnormal signals located in cortical sulcus and subcortex. Point and linear hypointensity could be seen on T2* or susceptibility weighted imaging (SWI) -weighted image. Digital subtraction angiography was performed in one case, showing occlusion of cortical veins. Protein S decreased in two patients, two patients with hyperhomocysteinemia and one patient with antiphospholipid antibody syndrome. The clinical and imaging manifestations of three patients were spontaneously alleviated. Brain biopsy was performed in two patients, and meningeal biopsy was performed in one patient due to significant meningeal thickening.@*Conclusions@#The clinical manifestations and routine MRI of ICoVT lack specificity and are easy to be misdiagnosed. However, ICoVT patients are often associated with risk factors for thrombophilia. T2* or SWI sequences are sensitive to the diagnosis of ICoVT. Brain biopsy has implications for the diagnosis and it is helpful for differential diagnosis, but the indications should be strictly controlled.

Massive cerebral venous sinus thrombosis secondary to Graves' disease / 영남의대학술지

Cerebral venous sinus thrombosis (CVT) is a rare cerebrovascular condition accounting for 0.5–1% of all types of strokes in the general population. Hyperthyroidism is associated with procoagulant and antifibrinolytic activity, thereby precipitating a hypercoagulable state that predisposes to CVT. We report the case of a 31-year-old Korean man with massive CVT and diagnosis of concomitant Graves' disease at admission. Early diagnosis and prompt treatment of CVT are important to improve prognosis; therefore, CVT should be considered in the differential diagnosis in all patients with hyperthyroidism presenting with neurological symptoms.

Cerebral Venous Sinus Thrombosis in a Child with Idiopathic Nephrotic Syndrome: a case report / Trombose Venosa Cerebral na apresentação de Síndrome Nefrótica Pediátrica: caso clínico

ABSTRACT Complications are rare in pediatric cases of idiopathic nephrotic syndrome (NS). Thromboembolism ranks among the most uncommon and difficult complications to diagnose, particularly in the first episode of NS, since clinical signs might be unspecific. This report describes the case of a 5-year-old girl with NS for the first time presenting with severe hypoalbuminemia (< 2g/dL). The patient responded poorly to therapy with corticosteroids. On day 8 of hospitalization she started having headaches and vomiting; she did not present hemodynamic alterations, fever or exanthems, and her neurological parameters were normal. The patient was suspected for intracranial hypertension, and computed tomography scans revealed she had cerebral venous sinus thrombosis (CVST). She was started on anticoagulants and showed clinical signs of improvement. The patient had no evident prothrombotic risk factors. She had three other episodes since she was diagnosed, one in which her plasma antithrombin level was low. Although antithrombin levels were normal in her first episode, she was tested after the resolution of proteinuria. The low levels of antithrombin seen in the first recurrence might have mirrored the initial drop in plasma antithrombin levels, an idea supported by the severe hypoalbuminemia she had when diagnosed. This severe manifestation of acquired thrombophilia might be in the origin of CVST. This report presents a rare case of thromboembolic complication in a pediatric patient with NS. The patient progressed well since she was started on anticoagulants. Although she did not present any evident risk factors at first, the development of her case indicated that severe acquired thrombophilia might have worked as the pathophysiological mechanism leading to CVST.

RESUMO A Síndrome Nefrótica (SN) idiopática em crianças pode, raramente, complicar-se. O tromboembolismo é uma das complicações mais raras, principalmente no primeiro episódio, e de diagnóstico mais difícil, uma vez que a clínica pode ser inespecífica. Descrevemos o caso de uma criança de 5 anos com episódio inaugural de SN, destacando-se hipoalbuminemia inicial grave (< 2g/dL). Apresentou fraca resposta inicial à corticoterapia e, após 8 dias de internamento, iniciou quadro de cefaleias e vômitos, sem alterações hemodinâmicas, sem febre, sem exantema e com exame neurológico normal. Perante a suspeita de hipertensão intracraniana, foi realizada TC-CE, que mostrou trombose venosa cerebral (TVC). Foi então iniciada terapêutica anticoagulante com posterior boa evolução clínica. Trata-se de uma criança sem fatores de risco pró-trombóticos evidentes. Desde o diagnóstico, teve 3 recaídas, uma das quais com níveis baixos de antitrombina, que no episódio inaugural eram normais, apesar de avaliados já numa fase não proteinúrica. Suspeita-se, assim, que esse déficit plasmático em antitrombina na recaída poderá mimetizar a queda plasmática inicial, hipótese também apoiada pela hipoalbuminemia grave ao diagnóstico. Esta trombofília grave adquirida poderá ter sido mecanismo etiológico para a trombose venosa cerebral. O interesse deste caso prende-se com a raridade de complicações tromboembólicas na SN Pediátrica, ainda mais raras no episódio inaugural. Nesse caso, a boa evolução foi possível após a associação da terapêutica anticoagulante. Embora sem fatores de risco iniciais evidentes, a evolução do caso permitiu a suspeita de uma trombofília adquirida grave como mecanismo fisiopatológico do tromboembolismo cerebral.

IgG4-Related Hypertrophic Pachymeningitis Mimicking Cerebral Venous Thrombosis

Immunoglobulin G4-related hypertrophic pachymeningitis (IgG4-RHP) is an increasingly recognized manifestation of IgG4-related disease (IgG4-RD), which is a fibroinflammatory condition that can affect virtually any organ. The three hallmark histopathological features of IgG4-RD are lymphoplasmacytic infiltration of IgG4-positive plasma cells, storiform fibrosis, and obliterative phlebitis. We report a case of biopsy-confirmed IgG4-RHP that was initially misdiagnosed as cerebral venous thrombosis.

Isquemia talámica bilateral secundaria a trombosis venosa cerebral: tratamiento endovascular, presentación de un caso / Bilateral thalamic stroke due to cerebral vein thrombosis: endovascular treatment, case report

RESUMEN La trombosis venosa cerebral (TVC) es una entidad poco frecuente y potencialmente devastadora que se presenta con mayor frecuencia en adultos jóvenes, especialmente en mujeres. La TVC representa el 0,5 % a 1 % de todos los ACV, su amplio espectro clínico la convierte en un desafío diagnóstico, especialmente en aquellos casos de mujeres jóvenes sin factores protrombóticos conocidos que debutan con cefalea como único síntoma. La TVC puede ocasionar isquemia o infartos talámicos y gangliobasales bilaterales con delirio y deterioro del estado de conciencia, en especial cuando hay compromiso del sistema venoso profundo. El diagnóstico se confirma con resonancia magnética cerebral (RM) y venografía por resonancia. La anticoagulación sigue siendo la piedra angular del tratamiento; sin embargo, los pacientes que no responden a terapia médica intensiva pueden beneficiarse de la trombectomía endovascular mecánica (TEM). A continuación presentamos el caso clínico de una paciente de 29 años con una isquemia talámica y gangliobasal bilateral secundaria a trombosis venosa cerebral que fue llevada a trombectomía endovascular mecánica.

SUMMARY Thrombosis of the dural sinus and/or cerebral veins (CVT) is a rare but potentially devastating type of stroke that tends to occur in young adults, especially women. CVT represents about 0.5% of all strokes and can be challenging to diagnose because headache, rather than focal neurologic symptoms, is the prominent feature. However, some patients (especially those with deep cerebral venous occlusion) may present with bilateral thalamic or basal infarction and often will have decreased level of consciousness and rapid neurologic deterioration. The diagnosis of CVT is confirmed with MRI and magnetic resonance venogram (MRV). The mainstay of acute management is anticoagulation. However, some patients do not respond to medical therapy and these might benefit from endovascular mechanical thrombectomy. We present the case of a 29 year old female patient with bilateral thalamic and gangliobasal ischemia secondary to CVT, who was treated with anticoagulation and endovascular mechanical thombectomy.

Trombosis venosa cerebral en una paciente puérpera con preeclampsia con datos de severidad / Cerebral venous thrombosis in a post-partum patient with preeclampsia with signs of severity

Resumen ANTECEDENTES: la trombosis venosa cerebral es infrecuente, pero con mayor incidencia durante la gestación y el puerperio. OBJETIVO: revisar la bibliografía más reciente y proponer una opción de tratamiento de la paciente con trombosis venosa cerebral durante el puerperio. CASO CLÍNICO: paciente de 30 años de edad, con antecedente de dos embarazos y dos cesáreas. En el séptimo día de puerperio tuvo edema de miembros inferiores, cifras tensionales elevadas, cefalea y alteraciones visuales. Con el tratamiento antihipertensivo con nifedipino y neuroprotección con sulfato de magnesio se logró el control de la hipertensión, aunque persistieron la cefalea y los síntomas de visión borrosa y diplopía. La resonancia magnética reportó: trombosis venosa de seno transverso lateral izquierdo. Con el tratamiento anticoagulante hubo disminución importante de los síntomas neurológicos. CONCLUSIONES: puesto que la preeclampsia y la eclampsia pueden ocultar los síntomas de la trombosis venosa cerebral, es importante tener siempre en mente ambos padecimientos para el diagnóstico y tratamiento oportuno de uno y otro.

Abstract BACKGROUND: cerebral venous thrombosis is infrequent, but with the highest incidence during pregnancy and puerperium. OBJECTIVE: to review the most recent bibliography and propose a treatment option for the patient with cerebral venous thrombosis during puerperium. CLINICAL CASE: a 30 year old patient with a history of two pregnancies and two Cesarean sections. On the seventh day of puerperium she presented edema of the lower limbs, high blood pressure, headache and visual disorders. Antihypertensive treatment with nifedipine and neuroprotection with magnesium sulfate, hypertension was controlled although the headache and blurry vision and double vision symptoms persisted. The MRI results reported: venous thrombosis of the left lateral transverse sinus. With anticoagulant treatment there was significant decrease of neurological symptoms. CONCLUSIONS: since preeclampsia and eclampsia can hide symptoms of cerebral venous thrombosis, it is important to always consider both conditions for the timely diagnosis and treatment of both.

Pathophysiology and etiology of cerebral venous thrombosis / 国际脑血管病杂志

Cerebral venous thrombosis (CVT) refers to thrombosis of the intracranial veins and sinuses, which is a rare type of cerebrovascular disease.Due to this highly variable and nonspecific clinical presentations, CVT can be difficult to diagnose.Understanding the pathophysiology and etiology of CVT helps to understand its clinical symptoms and imaging findings and guide the treatment.This article reviews the related advances in the pathophysiology and etiology of CVT.

Diagnostic and Therapeutic Strategies for Acute Intracranial Atherosclerosis-related Occlusions / 대한뇌졸중학회지

Intracranial atherosclerosis-related occlusion (ICAS-O) is frequently encountered at the time of endovascular revascularization treatment (ERT), especially in Asian countries. However, because baseline angiographic findings are similar between ICAS-O and embolism-related occlusion (EMB-O), it is difficult to differentiate the etiologies before the ERT procedure. Moreover, despite successful randomized trials on ERT, results from studies examining the optimal treatment protocol in ICAS-O patients remain unclear. In this review, we describe the clinical and imaging factors that may possibly differentiate ICAS-O from EMB-O. We will also discuss some current hurdles for treating ICAS-O in the hyperacute period and suggest the optimal ERT strategy for ICAS-O patients.

Clinical and imaging features of cerebral cortical vein thrombosis / 国际脑血管病杂志

Objective To investigate the clinical and imaging features of cerebral cortical vein thrombosis (CoVT). Methods The clinical data of 13 inpatients with CoVT were enroled from September 2010 to September 2015. The etiology, clinical symptoms, imaging features, and differential diagnosis of CoVT w ere summarized and analyzed. Results Among the patients, there w ere 7 females (53.85%) and 6 males (46.15%). Their age ranged from 18 to 59 years (mean 34.23 ±12.08). The most common clinical manifestations were headache (9 patients) and seizures (9 patients). The 13 patients had cerebral parenchymal involvement and they al received anticoagulant therapy. Conclusions The clinical symptoms of CoVT are various. Seizures and headache are the most common symptoms. Most of patients are accompanied by brain parenchymal lesions and venous sinus thrombosis. When patients have headache and seizures, and head images suggest hemorrhagic infarction, imaging examination of the improvement of the cerebral venous system thrombosis is recommended.
