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...

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...

Developmental venous anomalies (DVAs) are the most common type of cerebral vascular malformations. They are generally accepted as variants of venous development and frequently identified incidentally, particularly on contrast-enhanced MR imaging. Most of the DVAs do not affect the integrity of the surrounding parenchyma. This article discusses an atypical DVA which is associated with contrast enhancement and increased perfusion within the drainage territory of the DVA, probably due to anomalous venous drainage...

BACKGROUND AND PURPOSE: Developmental venous anomalies are considered variants of venous development that, in and of themselves, are of little clinical import. A possible association between intrinsic brain tumors and developmental venous anomalies has been suggested, but a rigorous investigation has not been performed. The aim of this study was to assess any association between developmental venous anomalies and intrinsic brain neoplasms. MATERIALS AND METHODS: A radiology report text search of terms used to describe developmental venous anomalies was performed on a study population of 580 patients with primary intracranial neoplasms and on a control population of 580 patients without neoplasms from the same time period...

Cavernous malformations (CM) are vascular malformations of the central nervous system that may occur in the brain and spinal cord. They are one of the four major types of vascular malformations that also includes developmental venous anomalies (DVA)s, arteriovenous malformations (AVMs), and capillary telangiectasias. CMs are a common vascular malformation, and 25% of them occur in the pediatric age group. They can present with acute or chronic symptoms including headache, neurologic deficits secondary to hemorrhage, mass effect, or epilepsy...

BACKGROUND: Symptomatic cavernous malformations involving the brainstem are frequently difficult to access via traditional methods. Conventional skull-base approaches require significant brain retraction or bone removal to provide an adequate operative corridor. While there has been a trend toward limited employment of the most invasive surgical approaches, recent advances in endoscopic technology may complement existing methods to access these difficult to reach areas. CASE DESCRIPTIONS: Four consecutive patients were treated for symptomatic, hemorrhagic brainstem cavernous malformations via fully endoscopic approaches (endonasal, transclival; retrosigmoid; lateral supracerebellar, infratentorial; endonasal, transclival)...

BACKGROUND: Nowadays, developmental venous anomaly (DVA) is recognized as the most common cerebral vascular malformation. Most DVAs are diagnosed incidentally on routine brain imaging, but they are occasionally symptomatic. We report the case of a 26-year-old Japanese woman with intracerebral hemorrhage due to venous thrombosis of DVA. METHODS: We examined her neurologic examinations carefully. We also observed her laboratory data, brain computed tomography (CT), and magnetic resonance imaging (MRI) findings...

BACKGROUND: Developmental venous anomalies (DVAs) are the most common intracranial vascular malformations of the brain. They are most commonly asymptomatic and often diagnosed incidentally. ILLUSTRATIVE CASE: We present a rare case of a 9-year-old boy with seizures caused by a subcortically located DVA posterior to the postcentral gyrus of the left brain hemisphere. MRI also showed an enlarged, microcystically altered pineal gland and an extracranial cavernous hemangioma...

BACKGROUND: Once considered inoperable lesions in inviolable territory, brainstem cavernous malformations (BSCM) are now surgically curable with acceptable operative morbidity. Recommending surgery is a difficult decision that would be facilitated by a grading system designed specifically for BSCMs that predicted surgical outcomes. OBJECTIVE: Informed by our efforts to develop a supplementary grading system for arteriovenous malformations, we hypothesized that a similar system might predict long-term outcomes and guide clinical decision-making...

BACKGROUND AND PURPOSE: Hereditary hemorrhagic telangiectasia is an autosomal dominant disease that presents in 10%-20% of patients with various brain vascular malformations. We aimed to report the radiologic features (phenotype) and the genotype-phenotype correlations of brain vascular malformations in hereditary hemorrhagic telangiectasia. MATERIALS AND METHODS: Demographic, clinical, genotypic, and imaging information of 75 patients with hereditary hemorrhagic telangiectasia with brain arteriovenous malformations enrolled in the Brain Vascular Malformation Consortium from 2010 to 2012 were reviewed...
