Developmental venous anomalies of brain

Keng-Liang Kuo, Feng-Ji Tsai, Yao-Ju Liu, Yu-Kai Huang, Ann-Shung Lieu
Developmental venous anomaly (DVA) is now considered common and benign disease within the field of cerebral vascular malformation. Though symptomatic DVA is uncommon, further management is necessary to alleviate the symptoms and signs induced by symptomatic DVA, such as parenchymal hemorrhage, venous infarction, brain edema, obstructive hydrocephalus, and nerve root compression. From the viewpoint of obstructive hydrocephalus, mostly resulted from obstruction of aqueduct of Sylvius. Herein, we reported a case with presentation of obstructive hydrocephalus caused by DVA induced fourth ventricle outlet obstruction...

We report the finding of increased F-DOPA uptake within parenchyma surrounding a developmental venous anomaly, found incidentally in a 64-year-old woman undergoing PET scan to assess for Parkinson's disease. Not identified on previous T1/T2 MRI, susceptibility-weighted imaging MRI performed post-PET scan demonstrated the presence of developmental venous anomaly within the left cerebellar hemisphere. Focal uptake of F-DOPA may suggest the presence of a brain tumor and prompt invasive diagnostic investigations...

BACKGROUND AND PURPOSE: Transitional venous anomalies (TVAs) are rare cerebrovascular lesions that resemble developmental venous anomalies (DVAs), but demonstrate early arteriovenous shunting on digital subtraction angiography (DSA) without the parenchymal nidus of arteriovenous malformations (AVMs). We investigate whether arterial spin labeling (ASL) magnetic resonance imaging (MRI) can distinguish brain TVAs from DVAs and guide their clinical management. METHODS: We conducted a single-center retrospective review of patients with brain parenchymal DVA-like lesions with increased ASL signal on MRI...

Developmental venous anomalies are cerebral vascular malformations that present normal venous drainage of cerebral tissue. With increased and accessible usage of modern diagnostic tools, they are now one of the most commonly diagnosed cerebral vascular malformations. Although developmental venous anomalies are considered to be benign lesions, association with arteriovenous malformation renders malignant potential to this combined pathology. In the case presented, these malformations were clinically silent and diagnosed accidentally, so they were not treated either with surgery, endovascular surgery or radiosurgery, considering the possible complications such as venous infarction of the brain, and because there was no obvious neurologic deficit related to this pathology...

INTRODUCTION: Arachnoid cysts are benign developmental anomalies of arachnoid membrane origin that can occur anywhere along the neuro-axis. They are believed to develop from the splitting or duplication of the arachnoid membrane by CSF that is trapped by a ball-valve mechanism. Intracranial arachnoid cysts have only been described as intradural lesions while spinal arachnoid cysts can be both intradural or extradural. CASE REPORT: After an extensive literature review, we report the first case of an intracranial, extradural arachnoid cyst in a 5-yearold girl...

BACKGROUND: Classification of cerebrovascular malformations has revealed intermediary lesions that warrant further review owing to their unusual presentation and management. We present 2 cases of arteriovenous malformation (AVM) associated with a developmental venous anomaly (DVA), and discuss the efficacy of previously published management strategies. METHODS: Two cases of AVMs associated with DVA were identified, and a literature search for published cases between 1980 and 2016 was conducted...

PURPOSE: Developmental venous anomalies (DVA) are common neuroimaging abnormalities that are traditionally diagnosed by contrast-enhanced T1-weighted images as the gold standard. We aimed to evaluate the sensitivity of SWI in detecting DVA and associated cavernous malformations (CM) and microhemorrhages in children in order to determine if SWI may replace contrast-enhanced MRI sequences. METHODS: Contrast-enhanced T1-weighted images were used as diagnostic gold standard for DVA...

OBJECTIVE: To describe the prenatal imaging features enabling diagnosis of developmental venous anomalies (DVA). METHODS: Four fetuses with unexplained persistent echogenic parenchymal brain lesions were studied. The evaluation included dedicated neurosonography, fetal MRI, serology for intrauterine infection, screening for coagulation abnormalities, and chromosomal microarray. Postnatal neurodevelopmental follow-up or autopsy results were assessed. RESULTS: DVA presented as very slowly growing echogenic brain lesions without cystic components, calcifications, or structural changes on otherwise normal neurosonographic scans performed at 2- to 3-week intervals...

Elevated relative cerebral blood volume on perfusion MRI and increased uptake on C-methionine PET can be used to diagnose and guide biopsy of brain tumors but are not specific. We report increased uptake on C-methionine PET associated with 4 developmental venous anomalies (DVAs) in 3 children with brain tumors, which could potentially mimic tumor and misdirect biopsy. Because DVAs are not readily visible on CT, prevention of misdirected biopsy in patients with focally elevated C-methionine uptake and relative cerebral blood volume relies on close correlation with contrast-enhanced anatomic MRI to exclude DVA or other nonneoplastic etiology...

Developmental venous anomalies (DVAs) are congenital anatomical variants of normal venous drainage of normal brain. Although DVAs are often discovered on the occasion of a seizure, their involvement in epilepsy is poorly studied. Our objective was to determine whether DVA can cause seizures, in the cases where there is no associated lesion, including no cavernoma or dysplasia. Based on clinical history, cerebral MRI, EEG recording, and (18)F-FDG PET, we report 4 patients with DVA revealed by seizures. The first patient had a convulsive seizure caused by a hemorrhagic infarction due to thrombosis of her DVA...

PURPOSE OF REVIEW: Unruptured intracranial aneurysms and vascular malformations are detected more frequently because of the increased use and availability of brain imaging. Management of these entities requires knowledge of which patients are at high risk for hemorrhage and what treatment options are available. This article summarizes the epidemiology, natural history, and management strategies for unruptured intracranial aneurysms, arteriovenous malformations, cavernous malformations, developmental venous anomalies, and capillary telangiectasias...

BACKGROUND AND PURPOSE: Abnormal hypometabolism is common in the brain parenchyma surrounding developmental venous anomalies (DVAs), although the degree of DVA-associated hypometabolism (DVAAh) has not been quantitatively analyzed. In this study, we demonstrate a simple method for the measurement of DVAAh and test the hypothesis that DVAs are associated with a quantifiable decrement in metabolic activity. MATERIALS AND METHODS: Measurements of DVAAh using ratios of standardized uptake values (SUVs) and comparison to a normal database were performed on a cohort of 25 patients (12 male, 13 female), 14 to 76 years old, with a total of 28 DVAs (20 with DVAAh, seven with isometabolic activity, and one with hypermetabolic activity)...

Structural MRI of volunteers deemed "normal" following clinical interview provides a window into normal brain developmental morphology but also reveals unexpected dysmorphology, commonly known as "incidental findings." Although unanticipated, these anatomical findings raise questions regarding possible treatment that could even ultimately require neurosurgical intervention, which itself carries significant risk but may not be indicated if the anomaly is nonprogressive or of no functional consequence. Neuroradiological readings of 833 structural MRI from the National Consortium on Alcohol and NeuroDevelopment in Adolescence (NCANDA) cohort found an 11...

A 34-year-old man presented with an acute onset of upbeat nystagmus, slurred speech, and limb and truncal ataxias. The patient had a history of limb ataxia and gait disturbance previously treated as brainstem encephalitis with corticosteroids 3 years previously. Brain magnetic resonance imaging showed pontine developmental venous anomaly (DVA) and hemorrhagic infarction within the drainage territory of the DVA. Three months later, the patient exhibited recurrent limb ataxia, double vision, and numbness of the left side of the body...

BACKGROUND: Sturge-Weber syndrome is characterized by a facial port-wine stain associated with either or both a retinal angioma and a cerebral pial angioma. Because a pial angioma may not be evident on the initial imaging studies, individuals at risk for epilepsy are often not identified before their first seizure. The aim of this study is to identify predictive factors predisposing Sturge-Weber patients to epilepsy. METHODS: The medical archives and photography database of our institution were reviewed to identify Sturge-Weber Syndrome patients followed up between 1990 and 2015...

We report the finding of increased F-3,4-dihydroxyphenylalanine uptake of the brain parenchyma adjacent to developmental venous anomalies, incidentally discovered in 3 pediatric patients with diffusely infiltrating gliomas. One patient presented 3 developmental venous anomalies located distant from the tumor, whereas in the remaining 2 patients, the vascular anomalies were inside the tumoral area mimicking a focal area of increased tumor metabolism. In the setting of brain tumor imaging, focal increased F-3,4-dihydroxyphenylalanine uptake should be carefully interpreted in light of MRI findings, and nuclear medicine physicians should be aware of any incidental minor vascular abnormality for proper interpretation of PET data...

Developmental venous anomalies (DVAs) are the most common vascular malformation of the brain and are commonly identified on routine imaging of the brain. They are typically considered incidental findings, usually with no clinical significance. However the increasing identification of DVAs as a result of improved imaging technology has led to recognition of their association with a variety of abnormal imaging findings and clinically important conditions. This pictorial essay explores the suspected embryological origin, associated imaging features, and proposed pathophysiological mechanisms of DVAs in the pediatric population...

BACKGROUND: The practice of administering intravenous contrast to children varies by institution depending on their routine. OBJECTIVES: To assess the necessity of routine contrast administration in brain magnetic resonance imaging (MRI) of pediatric outpatients referred for chronic headache workups. METHODS: We conducted a retrospective review of consecutive pediatric brain MRI examinations performed during January and February 2014 in 30 pediatric outpatients referred for evaluation of chronic headache...

Developmental venous anomaly (DVA) is a common lesion formerly known as venous angioma. DVAs drain normal brain parenchyma; however, parenchymal abnormalities surrounding DVAs have been reported. Unilateral putamen and caudate calcification in the drainage territory of DVAs has so far been reported in 7 cases, all with deep venous drainage. We present two additional cases of DVAs, one with superficial and the other one with deep venous drainage, associated with basal ganglia calcifications. We emphasize that DVAs should be in the differential diagnosis of unilateral basal ganglia calcifications...
