ABSTRACT

Cerebral Arteriovenous malformations (AVMs) are presumed congenital anomalies of the blood vessels, which can increase intracranial pressure by uncertain mechanisms. We report the rare case of a 55-year-old male patient who complained about CSF rhinorrhea. Persisting CSF leakage prompted CT, which evidenced a bone defect in the right middle cranial fossa with protruding brain tissue. The diagnosis of a sphenoidal meningoencephalocele was made. Neuroimaging evidenced an AVM Spetzler Martin V. The lesion was targeted via an endonasal approach with resection of the herniated brain tissue and closure of the bony and dural defects. The postoperative course was uneventful without recurrence of the CSF fistula. Documentation of these cases is essential to come up with standardized therapeutical protocols and follow-up. Nevertheless, conservative management of the AVM and surgical repair of the bone defects is an appropriate approach in the first instance, depending on the morphology and characterization of the AVM (AU)


Las malformaciones arteriovenosas (MAV) son consideradas anomalías congénitas de los vasos sanguíneos; estas pueden aumentar la presión intracraneal a través de mecanismos inciertos. Reportamos el caso de un hombre de 55 años con presencia de rinolicuorrea de larga data. Se realizó la toma de una TC de cráneo, evidenciando un defecto óseo en la fosa craneal media derecha con protrusión de tejido cerebral, diagnosticando un meningoencefalocele esfenoidal. Las imágenes complementarias evidenciaron una MAV Spetzler-Martin V. La lesión fue tratada con un abordaje endonasal resecando el tejido cerebral herniado con cierre de los defectos dural y óseo. En el postoperatorio no hubo recurrencia de rinolicuorrea. La documentación de estos casos es esencial para generar protocolos estandarizados de tratamiento y seguimiento. En nuestra experiencia el manejo conservador de la MAV y el reparo quirúrgico de los defectos es un abordaje adecuado, teniendo en cuenta la morfología y caracterización de la MAV (AU)

ABSTRACT

A male 28-year-old patient complained of a dorsal mass that has been increasing in size in the last six months. The mass was painful, soft, no mobile, and no neurological symptoms or signs were documented. A vascular-type tumor was suspected and endovascular followed by open surgical resection was indicated. Histopathological revealed a rare case of an adult with a primary extranodal polymorphous hemangioendothelioma. Total resection was confirmed by tumor-free resection margin. The postoperative course was uneventful. Polymorph hemangioendothelioma is a rare vascular tumor. Preoperative endovascular embolization is recommended given the high vascular features of the lesion and, therefore, the high rate of bleeding during surgery, to achieve complete resection.
