ABSTRACT

INTRODUCTION: Reversible cerebral vasoconstriction syndrome is a clinicoradiological entity with a self-limiting course that manifests with recurrent episodes of thunderclap headache, and is associated with certain triggers. Recurrence is very rare, and the pathophysiology is thought to be related to altered autoregulation of the cerebrovascular tone. We present a clinical case that raises questions about possible recurrences and triggers. CASE REPORT: A 44-year-old woman with a history of multiple sclerosis treated with interferon beta-1b who had four episodes of thunderclap headache while resting, after completing a course of corticosteroids due to a flare-up of optic neuritis. Three years earlier, the patient had presented several episodes of explosive-onset headache during a self-limited period of one month, only occurring during sexual intercourse. In the year prior to our assessment, she had suffered three thunderclap headaches with similar characteristics, but they were triggered only by intense physical exercise. She had not consulted a physician about these events. A cranial computed tomography scan was performed after the administration of contrast media and a cerebral arteriography, which were consistent with cerebral vasoconstriction syndrome, and its reversibility was confirmed three months later. CONCLUSIONS: Reversible cerebral vasoconstriction syndrome shares a phenotypic expression with primary exertion headaches. It is associated with drugs with vasoactive effects, including interferons, and corticosteroids are associated with a worse prognosis, and such their administration should be avoided.


TITLE: Síndrome de vasoconstricción cerebral reversible. Recurrencia de cefaleas en trueno tras tratamiento con corticoides.Introducción. El síndrome de vasoconstricción cerebral reversible es una entidad clinicorradiológica de curso autolimitado que se manifiesta con episodios de cefalea en trueno recurrentes y que se asocia a determinados desencadenantes. La recidiva es muy poco frecuente y la fisiopatología se cree que está en relación con la alteración de la autorregulación del tono vascular cerebral. Presentamos un caso clínico que plantea cuestiones sobre posibles recurrencias y desencadenantes. Caso clínico. Mujer de 44 años con antecedente de esclerosis múltiple en tratamiento con interferón beta-1b que consultó por cuatro episodios de cefalea en trueno en reposo, tras finalizar un ciclo de corticoides por un brote de neuritis óptica. Tres años antes, la paciente había presentado varios episodios de cefalea de inicio explosivo durante un período autolimitado de un mes, únicamente producidos en el contexto de relaciones sexuales. El año previo a nuestra valoración padeció en tres ocasiones cefalea en trueno de características similares, pero exclusivamente desencadenadas con el ejercicio físico intenso. No había consultado por estos eventos. Se realizó una tomografía computarizada craneal tras la administración de contraste y una arteriografía cerebral, que fueron compatibles con síndrome de vasoconstricción cerebral, y se confirmó su reversibilidad tres meses después. Conclusiones. El síndrome de vasoconstricción cerebral reversible comparte expresión fenotípica con el grupo de cefaleas primarias por esfuerzo físico. Se asocia a fármacos con efectos vasoactivos, entre los que se encuentran los interferones, y los corticoides se asocian a un peor pronóstico, por lo que es importante evitar su administración.

ABSTRACT

La enfermedad de Crohn es una patología de etiología autoinmunitaria, con afectación predominante del aparato digestivo. Se trata de una enfermedad que se diagnostica a edad temprana y presenta un curso crónico con reagudizaciones. Estos brotes se suelen manejar de forma similar a un abdomen agudo en los pacientes que acuden a los servicios de urgencias, y no existe un consenso sobre cuáles serían las pruebas de imagen más adecuadas. Debido a esta controversia, se ha decidido realizar una revisión de la bibliografía actual sobre cuáles serían las pruebas de imagen indicadas (ya sea por rendimiento diagnóstico o por menor exposición a radiación ionizante) en el brote agudo de pacientes con enfermedad de Crohn


Crohn's disease is an autoimmune disease that predominantly affects the gastrointestinal tract. Crohn's disease is diagnosed at a young age and runs a chronic course with acute flare-ups. When patients with Crohn's disease present with flare-ups at the emergency department, they are usually managed in a way similar to patients with acute abdomen; there is no consensus about the most appropriate imaging work-up for patients with flare-ups of Crohn's disease. Thus, we decided to review the literature about the imaging tests indicated (whether related to their diagnostic performance or to lower exposure to ionizing radiation) for acute flare-ups in patients with Crohn's disease
