Síndrome del ocho y medio secundario a vasculopatía lúpica: presentación de un caso / Eight-and-a-half syndrome secondary to lupus vasculopathy: a case presentation

RESUMEN Introducción: El manejo diagnóstico y terapéutico en los pacientes con lupus eritematoso sistémico que desarrollan una afectación neuropsiquiátrica representa un reto, debido a la heterogeneidad de las formas en que puede presentarse y la ausencia de criterios diagnósticos. Objetivo: Reconocer las formas clínicas de presentación de los síndromes neuroftalmológicos que traducen afectación pontina. Presentación del caso: Hombre de 71 años con antecedente de lupus eritematoso sistémico con afectación neuopsiquiátrica, que de forma aguda desarrolla un cuadro emético en el curso de una emergencia hipertensiva seguido de una parálisis de la mirada horizontal hacia la izquierda, una oftalmoplejía internuclear posterior derecha y una parálisis facial izquierda. En la neuroimagen se constata una afectación multifocal con marcado daño pontino. Conclusiones: Reconocer las formas clínicas de presentación de estos trastornos neuroftalmológicos raros que generalmente se presentan de forma aguda/subaguda permite al neurólogo realizar el diagnóstico topográfico de la lesión a nivel protuberancial con elevada precisión desde la Sala de Urgencias, así como reducir los posibles diagnósticos diferenciales a una etiología vascular, desmielinizante u ocupativa de espacio(AU)

ABSTRACT Introduction: The diagnostic and therapeutic management of patients with systemic lupus erythematosus who develop a neuropsychiatric involvement represents one of the biggest challenges due to the heterogeneity of the ways in which it can occur and the absence of diagnostic criteria. Objective: To recognize the clinical forms of presentation of neurophthalmological syndromes that express pontine involvement. Case presentation: Seventy-one-year-old man with history of systemic lupus erythematosus with neuropsychiatric involvement who acutely develops an emetic episode in the course of a hypertensive emergency followed by a paralysis of the horizontal gaze to the left, a right-sided posterior internuclear ophthalmoplegia and a left facial palsy. In the neuroimaging, a multifocal involvement with marked pontine damage is observed. Conclusions: Recognizing the clinical forms of presentation of these rare neurophthalmological disorders that generally occur in an acute or subacute form allows the neurologist to perform the topographic diagnosis of the lesion at a protuberancial level with high precision from the time when the patient attends the Emergency Department and reduces the possible differential diagnoses to a vascular, demyelinating or occupational etiology of space(AU)

A Case of Bilateral Horizontal Gaze Palsy due to Pontine Hemorrhage

PURPOSE: To report a case of bilateral horizontal gaze palsy associated with pontine hemorrhage. METHODS: A 51-year-old man developed a sudden decrease in consciousness. Computed tomography reveal a pontine hemorrhage and infarctions of both basal ganglia. The mentality was recovered after conservative treatment, but he complained of difficulty in moving his eyes. We performed ophthalmic and radiologic evaluations to confirm a diagnosis of bilateral horizontal gaze palsy and to reveal the condition. RESULTS: On ophthalmic examination, his eye showed complete bilateral horizontal gaze palsy, but convergence and vertical eye movements were normal. Radiologic evaluation revealed a pontine hemorrhage, and the hemorrhagic area was consistent the bilateral paramedian pontine reticular formation (PPRF).

Neuro-Behcet's Disease Presenting with Foville Syndrome : A Case Report

A Foville syndrome is rare. A 46-year-old man with a 3-year history of Behcet's disease presented with a right facial palsy and a limitation in the rightward movements of the eyes. On neurologic examination, there was no movement of eyes in the right hemifield during all kinds of eye movements, including saccade, smooth pursuit, vestibulo-ocular reflex, and optokinetic nystagmus. However, all the eye movements were normal in the left hemifiled except for slowed saccades toward the right. Additional features were right infranuclear facial paresis and extensor plantar response on left side. Brain MRI revealed high signal intensity lesions in the right pons both in the dorsal tegmentum and in the basis. Neurological signs resolved gradually with steroid treatment. Different clinical features between abducens nucleus syndrome and paramedian pontine reticular formation syndrome are briefly discussed. To the authors' knowledge, this is the first case report of a Foville syndrome caused by neuro-Behcet's disease.
