Cavernoma intraventricular del foramen de Monro: particularidades derivadas de su localización atípica / Intraventricular cavernoma in the foramen of Monro: particularities due to its atypical location

A pesar de que los cavernomas son malformaciones vasculares relativamente frecuentes en el sistema nervioso central, su localización intraventricular, especialmente en la región del foramen de Monro, es muy poco común. Esta localización atípica les confiere una serie de rasgos diferenciales, tanto clínicos como radiológicos, que pueden dificultar en extremo su diagnóstico preoperatorio y conducir a procedimientos ineficaces, como la radioterapia o el abordaje quirúrgico neuroendoscópico, e incluso peligrosos para el paciente, como la biopsia estereotáxica.Dado lo infrecuente de la patología y con el fin de ilustrar estas dificultades diagnósticas, se presenta a continuación un caso de cavernoma intraventricular de la región del foramen de Monro (AU)

Although cavernomas are relatively common vascular malformations in the central nervous system, they are rarely located in the ventricles and are even more rarely located in the region of the foramen of Monro. This atypical location results in a series of differential clinical and radiological characteristics that can make the diagnosis of these lesions extremely difficult and lead to inefficacious procedures like radiotherapy or a neuroendoscopic surgical approach or even to procedures that endanger the patient like stereotactic biopsy.We present a case of intraventricular cavernoma in the region of the foramen of Monro with the aim of illustrating the difficulties involved in the diagnosis of this rare lesion (AU)
