“…In adults, this pathology has been described by some authors 3,6,7,[14][15][16][17][18][19][20] . Because of its rarity in adults, and despite what is known from these studies, there is still insufficient information about this disease during adult age 13 .…”

-Vein of Galen aneurysm is a rare pathology, representing less than 1% of intracranial vascular malformations. We report on a 65 years-old man who experienced a generalized tonic-clonic seizure. Brain imaging showed a large calcified expanding mass in the pineal region, confirming the diagnosis of a vein of Galen aneurysm. Because of the spontaneous thrombosis of the malformation, there was no need for microsurgical or endovascular treatment and he is been regularly followed since that.KEY WORDS: vein of Galen aneurysm, vein of Galen malformation, cerebral vein, congenital vascular malformation. Aneurisma da veia de Galeno em adulto: relato de casoRESUMO -Aneurisma da veia de Galeno é patologia rara, representando menos de 1% das malformações vasculares intracranianas. Apresentamos o caso de um homem de 65 anos que teve episódio de crise convulsiva tônico-clônica generalizada. Exames de imagem evidenciaram grande processo expansivo calcificado na região pineal, confirmando o diagnóstico de aneurisma trombosado de veia de Galeno. Devido à trombose espontânea da malformação, foi excluída a possibilidade de tratamento endovascular bem como microcirúrgico, mantendo-se o acompanhamento clínico. PALAVRAS-CHAVE: aneurisma da veia de Galeno, mal-formação da veia de Galeno, veias cerebrais, malformação vascular congênita.Vein of Galen aneurysm (VGA) is a rare vascular malformation representing less than 1% of vascular intracranial abnormalities. It is a congenital process frequently detected between the 6 th and 11 th months of gestational age 1 , during early childhood or neonatal period 2 . This finding in adult age is very rare, presenting or not symptoms throughout childhood 3 . Clinical manifestations can present at any age in the form of heart failure, delayed neuropsychomotor development, hydrocephalus and seizures 4 .We describe a case of VGA reporting clinical symptoms, radiological findings and management relating to current published literature. CASEA 65 year-old man was brought to the emergency room at the University Hospital of the Pontifical Catholic University of Paraná, Brazil because of generalized tonic-clonic seizures. On admission, he was treated with anticonvulsant therapy for status epilepticus. Past medical history was significant for treated high blood pressure and heart failure diagnosed late in life. Also significant for an episode of ischemic cerebrovascular disease two years before, resulting in left hemiparesis. During childhood and adult life there was no neuropsycomotor development delay, no signs of cardiopathy, no neurological signs or symptoms as well as no history of epilepsy.CT scan showed a calcified expanding process in the pineal region (Fig 1). MRI showed a heterogenic roundshaped mass localized in the supra-vermian cistern with dimensions of 35x32x30 mm showing high signal in T2-weight imaging (Fig 2). The MRI images were suggestive of a thrombosed VGA. Cerebral angiography showed a thrombosed VGA also (Fig 3).Considering the fact that the aneurysm was already thrombosed ...

“…It is less common for choroidal‐type GPAVFs to manifest as hydrocephalus in adults (Abe et al, ; Kleindienst et al, ; Alami and Maaroufi, ) than during the neonatal period. Adult presentations characteristically include headache, intracranial/subarachnoid hemorrhage (Porzionato et al, ), and seizures, with hydrocephalus (Hoffman et al, ; Fernandez et al, ; Black and Farhat, ) complicating only approximately one third of cases. Headache in patients with VGAMs could indicate hemorrhage with meningeal irritation/intracranial hypertension, or simply distention of the VG (Gold et al, ).…”

Vein of Galen (VG) aneurysmal malformations (VGAMs) are complex vascular lesions. Their etiopathogenesis is extensively debated and remains poorly understood. Strictly speaking, true VGAMs are Galenic pial arteriovenous fistulas. They are believed to arise in utero and are contended to drain either into the true VG or the median prosencephalic vein of Markowski. Several classification systems have been proposed and are widely used. With the advent of endovascular therapy, precise understanding of the angioarchitecture is critical for management and therapeutic decision making. We review clinical presentation and diagnostic imaging findings, discussing angioarchitectural properties as they relate to treatment planning. Clin.

“…The study of the vessels of the brain base is one of our fields of research (De Caro et al, 1990, 1991, 1995, 1996, 1998, 2000Porzionato et al, 2004;Macchi et al, 2005;Parenti et al, 2005). We studied the PICA on 40 autoptic brains , and we were able to analyze the origin and the whole course of 80 PICAs, with reference to the five segments described by Lister et al (1982), which were recognizable on both sides.…”
