| Abstract (English): | Introduction: Migraine is a disorder characterized by episodic headache attacks associated with other neurological symptoms in some patients. Objective: Describe the imaging findings in patients who meet the criteria for migraine, using conventional magnetic resonance imaging (MRI), in order to evaluate its usefulness in the diagnosis of this pathology. Method: Retrospective study. Patients with a diagnosis of migraine according to established criteria who had undergone brain MRI between 2010 and 2021 were included. Clinical data and imaging findings were recorded. Results: A total of 376 patients were included, 327 (87%) were female. The median age was 39 years (IQR: 27-54). Foci of gliosis were found in 94 patients (25%). Intracranial aneurysms were found in 18 patients (4.8%). In 12 patients (3.2%) we found cerebellar tonsil descent > 3 mm. In 13 patients (3.5%) expansive lesions were found; the most frequent were meningiomas (n = 5). Lack of response to treatment (chronic migraine) was significantly associated with gliosis foci (p = 0.017) and with cerebellar tonsil shrinkage (p = 0.036). Conclusions: The presence of gliosis foci and cerebellar tonsil descent correlated with a lack of response to migraine treatment. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): | Introducción: La migraña es un trastorno caracterizado por ataques de cefalea episódica asociada a otros síntomas neurológicos en algunos pacientes. Objetivo: Describir los hallazgos en imagenología de pacientes que cumplen con los criterios de migraña, utilizando resonancia magnética (RM) convencional, con el fin de evaluar su utilidad en el diagnóstico de esta patología. Método: Se realizó un estudio de cohorte retrospectivo. Se incluyeron pacientes con diagnóstico de migraña según criterios establecidos que se hubieran realizado RM de cerebro entre 2010 y 2021. Se registraron datos clínicos y hallazgos imagenológicos. Resultados: Se incluyeron 376 pacientes, de los que 327 (87%) eran mujeres. La mediana de edad fue de 39 años (RIC: 27-54). Se encontraron focos de gliosis en 94 pacientes (25%). En 18 pacientes (4,8%) se encontraron aneurismas intracraneanos. En 12 pacientes (3,2%) se encontró descenso de las amígdalas cerebelosas > 3 mm. En 13 pacientes (3,5%) se encontraron lesiones expansivas; las más frecuentes fueron meningiomas (n = 5). La falta de respuesta al tratamiento (migraña crónica) tuvo asociación significativa con los focos de gliosis (p = 0,017) y con el descenso de las amígdalas cerebelosas (p = 0,036). Conclusiones: La presencia de focos de gliosis y el descenso de las amígdalas cerebelosas se correlacionaron con falta de respuesta al tratamiento de la migraña. [ABSTRACT FROM AUTHOR] |
