“…In addition, DVAs also have a higher prevalence in patients with venolymphatic‐lymphatic malformations of the head and neck and blue rubber bleb nevus syndrome . In a study of 580 pediatric patients with brain neoplasms, the prevalence of DVAs in patients with intracranial primary neoplasms was significantly greater than in those without neoplasms, versus normal controls . An association between abnormal parenchymal veins and DVAs with migrational brain anomalies has also been reported …”

Developmental venous anomalies (DVAs) are the most common cerebral vascular malformations and are usually found incidentally on neuroimaging studies. Despite the benign nature of DVAs, occasionally, they can be symptomatic. The objective of this article is to review the spectrum of imaging findings of DVAs on conventional and advanced imaging studies. In addition, neuroimaging findings of symptomatic DVAs as well as imaging mimicks will also be described to assist in the approach to differential diagnosis.

“…They were once thought to be rare, but are now considered to be the most common vascular malformation in the central nervous system (1,2). Angiograms show a "hydra" or caput medusae appearance as a result of smaller radial veins converging on a central draining venous vein.…”

Developmental venous anomaly (DVA) is an extreme variation of the normal transmedullary vein, which is necessary for the normal venous drainage of an area of the brain. It occurs in as many as 2% of individuals. In most cases, it is considered to be an incidental finding, however it can be symptomatic under very rare circumstances. The possible pathomechanism of symptomatic DVA is broadly divided into mechanical and flow-related. The flow-related pathomechanism accounts for the majority of cases. Susceptibility weighted magnetic resonance imaging study is the imaging modality of choice in all vascular anomalies because it can detect even very remote vascular abnormalities and its superiority over conventional imaging can never be over emphasized. Irrespective of the pathomechanism of DVA, conservative management remains the treatment of choice. This case of symptomatic DVA is presented to buttress the fact that though most symptomatic venous anomalies are associated with hemorrhage from cavernoma, in rare cases, symptoms may arise from DVAs that are not associated with other vascular malformations.Keywords: Developmental venous anomaly, susceptibility-weighted images, perfusion magnetic resonance imaging Gelişimsel venöz anomali (GVA) beynin bir bölgesinin normal venöz drenajı için gerekli olan normal transmedüller venin sıradışı bir varyasyonudur. Normal popülasyonda %2 oranında görülür. Çoğu olguda bu durum tesadüfi bir bulgu olarak gözlenmiştir, ancak çok nadir durumlarda semptomatik olabilir. Semptomatik GVA'nın muhtemel patomekanizması genel olarak mekanik ve akım ilişkili olarak ayrılmıştır. Olguların çoğunu akım ilişkili patomekanizma oluşturmaktadır. Manyetik rezonans incelemede 'susceptibility weighted imaging' sekansı tüm vasküler anomalilerde tercih edilen görüntüleme yöntemidir, çünkü çok uzak vasküler anormallikleri bile tespit edebilir ve konvansiyonel görüntülemeye göre üstünlüğü asla göz ardı edilemez. GVA'nın patomekanizması ne olursa olsun konservatif yaklaşım halen tercih edilen tedavi durumundadır. Bu semptomatik GVA olgusu, semptomatik venöz anormalliklerin çoğunun kavernoma bağlı kanama ile ilişkili olmasına rağmen, nadir durumlarda, diğer vasküler malformasyonlar ile ilişkili olmayan GVA'lara bağlı semptomların ortaya çıkabileceği gerçeğini desteklemek için sunulmuştur.

“…Ранее считалось, что венозные ангиомы являются ред-кой патологией, но в последние годы они считаются наибо-лее распространенными ВПР сосудов в центральной нерв-ной системе [30]. Большинство венозных ангиом никогда не вызывают симптомов, хотя часть из них могут стать при-чиной эпилепсии и прогрессирования неврологического дефицита на фоне кровоизлияния.…”
