Spinal dural arteriovenous fistula (SDAVF) is characterized by an abnormal connection between a radicular artery and the venous plexus producing spinal cord venous congestion. It manifests with nonspecific sensory and motor symptoms. We present three cases of SDAVF with different forms of presentation; in two cases, an autoimmune etiology was considered, and in the third case, the initial diagnosis was chronic radiculopathy. In all three cases, a serpentine enhancement was observed after the gadolinium in the dorsal region of the spinal cord corresponded to flow voids in T2-weighted images, which guided the diagnosis. SDAVF should be considered in atypical clinical presentations of radiculopathies or spinal cord syndromes, especially spinal conus or epicone syndrome. Likewise, it should be part of the differential diagnosis of spinal cord presentations of demyelinating diseases such as multiple sclerosis or neuromyelitis optica spectrum disorders.
La enfermedad de Moyamoya es una patología caracterizada por la estenosis progresiva de la arteria carótida interna y sus ramas principales. Es de etiología desconocida, tiene como forma de presentación a la enfermedad cerebrovascular isquémica o hemorrágica, siendo la primera más frecuente, y afecta en mayor proporción a niños y adultos jóvenes constituyendo un reto diagnóstico. Su presencia se confirma mediante la angiografía por sustracción digital (ASD) y el manejo es médico y/o quirúrgico, siendo el último el que se asocia a un mejor pronóstico. Comunicamos el caso de un paciente peruano de ascendencia japonesa, sin factores de riesgo, con una hemorragia intracraneal cuyo diagnóstico final fue enfermedad de Moyamoya.
Conflictos de interés: Los autores declaran no tener conflictos de interésResumen Los infartos limítrofes son aquellos ubicados en regiones entre dos territorios vasculares contiguos y la enfermedad inflamatoria orbitaria idiopática es un proceso inflamatorio orbitario inespecífico. Presentamos el caso de un varón de 60 años con exoftalmos, ptosis palpebral, disminución de agudeza visual derecha y afección de los nervios oculomotores derechos. Los estudios de imágenes mostraron una masa retro ocular derecha con invasión de los senos cavernosos y esfenoidal. Durante la hospitalización, el paciente sufrió un infarto cerebral limítrofe por compresión de la arteria carótida interna derecha en su segmento intracavernoso. La exéresis y la anatomía patológica de la lesión orbitaria fueron compatibles con la enfermedad inflamatoria orbitaria idiopática. Nuestro caso muestra a la enfermedad inflamatoria orbitaria idiopática como una causa inhabitual de infarto cerebral limítrofe.

Abstract Watershed cerebral infarctions are those located in regions between two adjacent vascular territories and Idiopathic orbital inflammatory disease is a nonspecific inflammatory process of the orbit. We report the case of a 60-year-old man who presented suddenly in the right eye: exophthalmos, ptosis, reduced visual acuity and paresis of the extraocular muscles innervated by the III, IV and VI cranial nerves. Imaging studies showed a right retro-ocular mass with invasion of the ipsilateral cavernous and sphenoid sinus. During hospitalization, suddenly he presented a watershed infarction with narrowing of the right internal carotid artery in its intracavernous portion. Surgical excision of the lesion was performed and pathology showed a characteristic infiltration of idiopathic orbital inflammatory disease. Our case shows idiopathic orbital inflammatory disease as an uncommon cause of watershed cerebral infarction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
