Abstract
Several mimics of acute ischemic stroke may complicate the decision to administer intravenous thrombolysis. Developmental venous anomalies (DVA) are fairly common variants of normal cerebral vasculature and may occasionally present with acute focal neurologic symptoms. We report a case of DVA presenting with the acute onset of focal neurologic deficits and focal hypodensities on the CT of the brain, resulting in a dilemma regarding whether to administer intravenous tissue-type plasminogen activator (IV tPA) for stroke thrombolysis. Recognition of subtle brain changes on the CT that were inconsistent with an acute ischemic stroke led to further imaging and a definitive diagnosis. Developmental venous anomalies should be considered in the differential diagnosis of acute ischemic stroke.

Abstract
OBJECTIVE Symptomatic developmental venous anomalies (DVAs) are rare. Here, we illustrate the varied clinicoradiologic profiles of symptomatic DVAs and contemplate the mechanisms that render these (allegedly) benign entities symptomatic supported by a review of literature. METHODS Institutional databases were searched to identify cases of symptomatic DVAs. Clinical and imaging (angiographic and cross-sectional) data of 9 cases with 11 neurovascular symptoms consequent to inflow/outflow perturbations and mechanical obstruction that manifested because of the strategic topography of underlying DVAs were analyzed. A review of the existing literature on DVAs in agreement with our case series was performed on publications retrieved from the PubMed database. RESULTS Symptoms secondary to venous hypertension arising from flow-related perturbations were broadly divided into those arising from restricted outflow and increased inflow. Restricted outflow occurred because of collector vein stenosis (n = 2) and collector vein/DVA thrombosis (n = 3), whereas the latter pathomechanism was initiated by arterialized/transitional DVAs (n = 2). A mechanical/obstructive pathomechanism culminating in moderate supratentorial ventriculomegaly was noted in 1 case. One patient was given a diagnosis of hemorrhage associated with a cavernoma. CONCLUSIONS Awareness and contextualization of potential flow-related perturbations and mechanical insults that render DVAs symptomatic aid in accurate diagnosis, management, and prognostication.

Abstract
OBJECTIVE The aim of this study was to describe different lesions and features associated with developmental venous anomalies (DVAs). METHODS The records and magnetic resonance imaging (MRI) images of 1,722 patients who underwent cranial MRI between 2010 and 2017 were retrospectively reviewed. It was found that 124 (7.2%) patients had DVAs, and 48 of these patients (38.7%) had additional anomalies accompanying DVAs. Of the patients with DVAs, 25 were female and 23 were male, with a mean age of 39.3 years (range, 3-77 years). MRI was performed in all the patients. RESULTS In addition to DVAs, cavernomas were present in 30 patients (62.5%), haematomas in 7 (14.5%), gliosis in 6 (12.5%), demyelinating plaques in 4 (8.3%) and a glioblastoma in 1 (2.2%). The mean diameter of the DVAs was 1.1mm and the mean diameter of the lesions was 17.4mm. The susceptibility weighted imaging (SWI) sequence was also applied to 12 patients with cavernomas. The relevant sequence in all of these patients contributed to the diagnosis. CONCLUSION Our study shows that DVAs can accompany a wide spectrum of lesions, especially cavernomas. Although their pathophysiology has not yet been clearly established, these lesions may have a common aetiology.

Abstract
Epilepsy is among one of the most common neurologic disorders. The role of magnetic resonance imaging (MRI) in the diagnosis and management of patients with epilepsy is well established, and most patients with epilepsy are likely to undergo at least one or more MRI examinations in the course of their disease. Recent advances in high-field MRI have enabled high resolution in vivo visualization of small and intricate anatomic structures that are of great importance in the assessment of seizure disorders. Familiarity with normal anatomic variations is essential in the accurate diagnosis and image interpretation, as these variations may be mistaken for epileptogenic foci, leading to unnecessary follow-up imaging, or worse, unnecessary treatment. After a brief overview of normal imaging anatomy of the mesial temporal lobe, this article will review a few important common and uncommon anatomic variations, mimics, and pitfalls that may be encountered in the imaging evaluation of patients with epilepsy.

Abstract
PURPOSE Developmental venous anomalies (DVAs) have been found to be more prevalent in patients with multiple sclerosis (MS). The aim of the study was to compare the prevalence of DVAs in a large population of patients with MS compared with controls and to investigate the correlation of 3D Fluid Attenuated Inversion Recovery (FLAIR) hyperintense signal abnormalities adjacent to DVAs between MS patients and controls having DVAs, as well as DVA potential role in differential diagnosis. METHODS Between January 2001 and December 2019, 349 patients who met the McDonald criteria for MS diagnosis (249 females, 100 males, age range 18-70 years) were retrospectively included in the study. All patients and 340 age-matched healthy controls had brain MRIs performed on a 1.5 Tesla MR system. Two radiologists reviewed all images to identify DVAs; their presence was compared between the MS and control groups. Among the subjects having DVAs, age, gender, adjacent FLAIR anomalies, and DVA location were compared between the two groups. RESULTS Fifty (14.3%) out 349 patients presented 51 DVAs (35 supratentorial and 16 infratentorial), in comparison to 21/340 (6.2%) controls (P = 0.0005). One patient showed 2 simultaneous DVAs, while 3 patients had coexisting pontine capillary telangiectasias. FLAIR white matter changes adjacent to DVAs were found in 46.2% of patients and in 28.1% of controls (P = 0.0001). CONCLUSIONS DVAs demonstrated a higher prevalence in the MS group in comparison to controls. We confirmed the association between DVAs and FLAIR anomalies in MS patients. However, currently there are no evidences that the presence of DVAs may be used in MS differential diagnosis.

Abstract
BACKGROUND Significant advances have been reported recently in the genetic and mechanistic characterization of extracranial venous malformations. However, intracranial purely venous malformations (icVM) analogous to those outside the CNS have not been systematically described. PURPOSE We sought to ascertain whether such an entity as icVM could in fact be identified, distinct from previously described CNS venous anomalies and analogous to extracranial venous malformations. METHODS Our prospectively collected pediatric cerebrovascular database was reviewed to identify patients with icVM; 1458 consecutive angiograms and/or angiographic interventions performed on 706 children at our institution from October, 2006 through May, 2019 were evaluated, in addition to outside imaging studies on 192 additional patients sent to our Vascular Anomalies Center for cerebrovascular review during the same time period. Thus, the cohort consisted of 898 children. RESULTS Nineteen of 898 patients (2.1%) were found to harbor icVM, including 9 (47.3%) with sinus pericranii, 15 (78.9%) with associated large, complex extracranial venous malformations, and 3 (15.7%) with neurocognitive delay. There was no intracranial hemorrhage or venous hypertension seen in the cohort. Asymptomatic venous thrombosis in the superior sagittal sinus was seen in three patients. CONCLUSION Venous malformations, both extracranial and icVM, share many characteristics that are distinct from developmental venous anomalies. icVM were not associated with venous hypertension. The underlying genetic mutations involved in the development of icVM, germ-line or somatic, remain to be elucidated, but may very well involve shared mechanisms and pathways with extracranial venous malformations.

Abstract
BACKGROUND Developmental venous anomalies (DVA) are rarely symptomatic. We report an unusual case of outflow-restricted DVA presenting with seizures. CASE DESCRIPTION Expansile signal changes due to a hemorrhagic venous infarction in the draining territory of collector vein of DVA simulated a neoplasm. Follow-up imaging showed regression of mass effect and asymptomatic thrombosis of another distant vein. Investigation for prothrombotic conditions returned negative. CONCLUSIONS Atypical imaging findings in the draining territory of DVA ought to raise the possibility of outflow restriction.

Abstract
PURPOSE Developmental venous anomalies (DVA) are congenital malformations of veins that drain brain parenchyma, with a prevalence up to 9.3% in normal populations and 29.5% in multiple sclerosis (MS) patients. Study purpose was to determine prevalence of DVAs in patients with clinically isolated syndrome (CIS) and early relapsing-remitting multiple sclerosis (RRMS) and to assess whether DVAs are related to altered clinical, magnetic resonance imaging (MRI) and cerebrospinal fluid (CSF) laboratory parameters. METHODS Routine neurological and MRI examinations took place in a single center in 93 patients (39 CIS, 54 RRMS). Clinical disability (n = 93), MRI (n ≤ 90), CSF (n ≤ 82) parameters and DVA status were determined and compared statistically. RESULTS A total of 29 DVAs were detected in 25 patients (25/93; 26.9%), 10 in 39 CIS patients and 15 in 54 RRMS patients. Most parameters were not significantly altered in patients with DVAs; no associated higher conversion rates from CIS to MS at 1-year (p = 0.411) or 2‑year follow-up (p = 0.281) were registered. CONCLUSION A higher prevalence of DVAs was detected in CIS and early MS patients than reported in non-MS populations, congruent to recent literature. The DVAs were not associated with significantly altered clinical outcomes, brain atrophy rates or disease progression, and no associated higher risk of CIS patients for converting to MS was found.

Abstract
OBJECTIVE Patients with a cerebral cavernous malformation (CCM) can have intracranial hemorrhages ranging from insignificant and chronic microbleeds to life-threatening hemorrhage. Management decisions and patient counseling are based on a heterogeneous body of evidence. We sought to improve the literature by providing our results based on the standardized definitions and aimed to delineate differences in the symptomatic burden for CCMs, based on their anatomic location and presence of developmental venous anomalies. This evidence will aid in clinical decision making and patient counseling. METHODS A retrospective cohort analysis between 1990 and 2018 was performed, including patients with a diagnosis of a CCM. The primary outcome was acute symptomatic hemorrhages. RESULTS We identified 438 patients harboring 632 CCMs. Mean age at diagnosis was 50 years (standard deviation ±17 years). Median follow-up was 26 months (interquartile range, 7-72 hours). Multiple lesions were encountered in 64 patients (15%). An initial symptomatic presentation was observed in 64% of the patients. There were 438 supratentorial lesions (69%) and 194 infratentorial lesions (31%). A symptomatic hemorrhage was observed in 25% of the supratentorial lesions and 29% of the infratentorial lesions (P < 0.001). A linear mixed-effects regression model showed a significant difference in developing a symptomatic hemorrhage at diagnosis or follow-up between CCMs with an infratentorial location and those with a supratentorial location (odds ratio, 1.81; 95% confidence interval, 1.17-2.81; P = 0.008). CONCLUSIONS Infratentorial cavernous malformations are more likely to present with symptomatic hemorrhages at diagnosis or during follow-up when accounting for size differences between lesions.

Abstract
Objective A developmental venous anomaly (DVA) is a vascular malformation of ambiguous clinical significance. We aimed to quantify the susceptibility of draining veins (χvein) in DVA and determine its significance with respect to oxygen metabolism using quantitative susceptibility mapping (QSM). Materials and Methods Brain magnetic resonance imaging of 27 consecutive patients with incidentally detected DVAs were retrospectively reviewed. Based on the presence of abnormal hyperintensity on T2-weighted images (T2WI) in the brain parenchyma adjacent to DVA, the patients were grouped into edema (E+, n = 9) and non-edema (E−, n = 18) groups. A 3T MR scanner was used to obtain fully flow-compensated gradient echo images for susceptibility-weighted imaging with source images used for QSM processing. The χvein was measured semi-automatically using QSM. The normalized χvein was also estimated. Clinical and MR measurements were compared between the E+ and E− groups using Student's t-test or Mann-Whitney U test. Correlations between the χvein and area of hyperintensity on T2WI and between χvein and diameter of the collecting veins were assessed. The correlation coefficient was also calculated using normalized veins. Results The DVAs of the E+ group had significantly higher χvein (196.5 ± 27.9 vs. 167.7 ± 33.6, p = 0.036) and larger diameter of the draining veins (p = 0.006), and patients were older (p = 0.006) than those in the E− group. The χvein was also linearly correlated with the hyperintense area on T2WI (r = 0.633, 95% confidence interval 0.333–0.817, p < 0.001). Conclusion DVAs with abnormal hyperintensity on T2WI have higher susceptibility values for draining veins, indicating an increased oxygen extraction fraction that might be associated with venous congestion.

Abstract
For years, the conventional imaging modalities are generally used in dental practice routine. They provide precious information about dentomaxillofacial region; they also have some limitations such as superimpositions, magnifications, distortions, and low-image quality. Because of these limitations, some pathologies, calcifications, and anatomical variations may be missed. Any findings on a radiographic image which are not related to the research areas of interest could be a description of “incidental findings.” Calcifications are one of these incidental findings. They are asymptomatic and also common in TMJ images. Although most of the calcifications require no treatment, correct identification will reduce further diagnostic assessments. Incidental findings on TMJ images were rare, while examining images for temporomandibular disorders and associated issues, it is important not only to examine the TMJ structures but also to look at the nearby anatomical features to check for evidence of incidental findings pathologies that may have mimicked signs and symptoms of TMJ disorders.

OBJECTIVE Multiple sclerosis (MS) is a demyelinating autoimmune disease of the central nervous system. T2W-hyperintense demyelinating lesions are detected in cranial magnetic resonance imaging (MRI). Developmental venous anomalies (DVAs) have frequently been detected in enhanced cranial MRI images, and are generally accepted as normal variants of venous development. The aim of the present study was to investigate whether there was an association between demyelinating diseases and venous anomalies. METHODS One hundred five patients who were diagnosed as having MS in accordance with the McDonald diagnostic criteria, and 105 patients who were diagnosed as having vascular headache who had no lesions similar to MS were included in the present retrospective study. RESULTS DVAs were detected in 31 of the study group and in 14 patients in the control group. A statistically significant higher rate of DVAs and abnormal signal increase in the neighboring tissue was detected in the study group (p = 0.004) (p = 0.006). The DVA was superficially localized in the RRMS, It was deeply located in RIS. CONCLUSION Recent studies have emphasized the association of the central vein and the lesion severity of MS with the detection of the central collecting vein in MS lesions. In our study, DVAs, which are generally regarded as innocent developmental anomalies, and neighboring signal increase were found significantly higher in the MS group compared with the control group. The role of DVAs in the etiology of demyelinating lesions must be clarified through comprehensive future studies that use more advanced techniques.

Abstract
BACKGROUND AND PURPOSE Demyelination is a recently recognized cause of FLAIR hyperintensities associated with developmental venous anomalies. Our purpose was to quantify the prevalence of white matter signal abnormalities associated with developmental venous anomalies in patients with multiple sclerosis compared with controls. MATERIALS AND METHODS A retrospective, blinded, multireader study compared the prevalence of FLAIR hyperintense signal abnormalities adjacent to developmental venous anomalies in patients with MS compared with controls (patients with developmental venous anomalies without MS). Study findings were positive if a central vein was demonstrated using FLAIR and contrast-enhanced fat-saturated T1 sequences. Imaging parameters also included developmental venous anomaly location, developmental venous anomaly drainage, white matter lesion size, and depth of white matter lesions. Clinical parameters included age, sex, and the presence of confounding variables (hypertension, diabetes, migraines, and/or vasculopathy). RESULTS FLAIR signal abnormality was present around 47.3% (35/74) of developmental venous anomalies in patients with MS, and 13.5% (10/74) of developmental venous anomalies in the control group (P < .001). The multivariate logistic regression model controlling for covariates (including migraines, hypertension, diabetes mellitus, vasculopathy, age, sex, and drainage direction of developmental venous anomalies) showed that the odds of FLAIR hyperintensity around developmental venous anomalies was 6.7-fold higher in patients with MS (relative risk MS = 6.68; 95% CI, 2.79-15.97; P < .001). CONCLUSIONS The association of developmental venous anomalies and FLAIR hyperintensities was more common in patients with MS, which suggests that the underlying demyelinating pathologic process of MS may be the cause of this propensity in patients with MS. Impaired venous drainage in the territory of developmental venous anomalies may predispose to development of these lesions, and an associated central vein is helpful in understanding an atypical location of MS plaques.

Abstract
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. Patient demographic data and clinical features were documented. RESULTS In case 1, a 29-year-old female presenting with parenchymal hemorrhage and left homonymous hemianopia was found to have a right parieto-occipital AVM fed from the anterior cerebral, middle cerebral, and posterior cerebral arteries, with major venous drainage to the superior sagittal sinus. In case 2, imaging in a 34-year-old female evaluated for night tremors and incontinence revealed a left parietal AVM with venous drainage to the superior sagittal sinus. Including our 2 cases, 22 cases of coexisting AVMs and DVAs have been reported in the literature. At presentation, 68% had radiographic evidence of hemorrhage. Stereotactic radiosurgery was performed in 7 cases, embolization in 6 cases, surgical resection in 4 cases, and multimodal therapy in 5 cases. Radiography at follow-up demonstrated successful AVM obliteration in 67% of cases (12 of 18). CONCLUSIONS Patients with coexisting AVMs and DVAs tend to have a hemorrhagic presentation. Contrary to traditional AVM management, in these cases it is important to preserve the draining vein via the DVA to ensure a safe, sustained circulatory outflow of the associated brain parenchyma while achieving safe AVM obliteration.

Abstract
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.

Abstract
Developmental venous anomalies (DVAs) are relatively common lesions, present in up to 3% of the population. The defining characteristic of these lesions is the confluence of radially oriented veins into a single dilated venous channel. DVAs are also known as cerebral venous angiomas, cerebral venous malformations, and cerebral venous medullary malformations. They are the most common type of cerebral vascular malformation found on autopsy studies, and they are often encountered as incidental findings on neuroimaging studies. DVAs are congenital lesions thought to arise from aberrations that occur during venous development, but continue to provide the normal venous drainage to the cerebral territory in which they reside. Although the natural history of DVAs is benign, they may be associated with cavernous malformations or other vascular abnormalities, which can lead to hemorrhage in the vicinity of the DVA. Surgical or endovascular obliteration of DVAs carries a significant risk of venous infarction; thus, conservative management is the treatment of choice for patients with these lesions.

Abstract
Background Developmental venous anomalies (DVAs) are rare vascular diseases becoming more frequently diagnosed. Most patients with DVAs have no clinical symptoms with the exception of a few patients with epilepsy, intracranial hemorrhage, or neuro-function deficit. There is still controversy with respect to treatment strategies for symptomatic DVAs. Material/Methods Forty-three cases of symptomatic DVAs from January 2006 to October 2015 were retrospectively reviewed and the imaging characteristics of DVAs by CT, MRI, and DSA and the treatment modalities for DVAs were studied. Results Typical imaging characteristics of symptomatic DVAs were wedge or umbrella-shaped collections of dilated medullary veins converging in an enlarged subependymal or transcortical collecting vein, draining to the superficial or deep vein system. Based on location and draining vein features, symptomatic DVAs were tentatively classified into six different subtypes. Of the 43 cases, 19 were treated by surgical methods and 24 were treated conservatively. Conclusions We concluded that the rate of accompanying abnormalities in cases of symptomatic DVAs was high. Intracerebral hemorrhage was usually attributed to associated CMs or AVMs. The associated lesions and the branches responsible for bleeding could be resected while preserving the collecting vein as far as possible.

Abstract
Background Past studies found that cerebral developmental venous anomaly (DVA) is often concurrent with cavernous malformation (CM). But the reason of the concurrency remains unknown. The purpose of this study was to confirm whether angioarchitectural factors relate to the concurrence and which angioarchitectural factors can induce the concurrency. Methods DVA cases were selected from the records of the same 3.0 T MR. The DVA cases was divided into two group which are DVA group and DVA concurrent with CM group. 8 angioarchitectural factors of the DVAs were selected and measured. Statistical analysis was performed by the Pearson chi-square statistic,analysis of variance (ANOVA) and multi-factor logistic regression analysis. Results Five hundred three DVA lesions were found and 76 CM lesions coexisting with DVA. In the single factor analysis, all the 8 angioarchitectural factors of DVA were related to the concurrency. In the multivariate analysis, 6 angioarchitectural factors. Result of multi-factor logistic regression analysis is Logit(P) = -4.858-0.932(Location) + 1.616(Direction) + 1.757(Torsion) + 0.237(Number) + 2.119(Stenosis rate of medullary vein)-0.015(Angle), goodness of fit is 90.1 %. Conclusions The angioarchitectural factors of DVA are related to the concurrency of DVA and CM. 6 angioarchitectural factors may induce the concurrency.

Abstract
Sono stati studiati con RM 29 pazienti con anomalie di drenaggio venoso in condizio-ni basali e dopo Gadolinio-DTPA; 24 sono stati sottoposti anche ad angio-RM. Nella valutazione dei risultati è stato assegnato un punteggio: 0 quando l'anomalia non era evidenziata; 1 per la rappresentazione del solo collettore; 2 per la dimostrazione del collettore e delle vene midollari; 3 per la dimostrazione del collettore, delle vene midollari e del tipo di drenaggio. È stata inoltre considerata la presenza di eventuali angiomi cavernosi associati e l'eventuale correlazione con la sintomatologia. Le sequenze SE Tl pesate dopo Gadolinio-DTPA in doppia dose sono risultate quelle con maggiore accuratezza diagnostica (score 77) sia rispetto alle sequenze basali (T1 score 12, T2 score 31) sia nei 24 pazienti sottoposti anche ad angio-RM (SE T1 dopo Gadolinio score 66, angio-RM score 61). L'angio-RM è risultata utile nell' evidenziare il tipo di drenaggio. In 5 casi l'anomalia di sviluppo venoso era associata ad un angioma cavernoso, in 4 casi le due malformazioni erano in stretto rapporto; solo in due casi però l'angioma cavernoso presentava il tipico aspetto a «pop-corn». In un solo paziente l'anomalia venosa si è presentata come evento emorragico, mentre in un altro caso era in stretto rapporto con un'area di basso segnale in T1 e T2, esito di una pregressa emorragia. Nel 34% i pazienti hanno presentato epilessia senza però una costante correlazione tra sede dell'ano-malia venosa e sede dell'anomalia elettroencefalografica.

Abstract
Purpose Venous angioma (VA) is the most common congenital abnormality of the intracranial vasculature. This study aimed to investigate the relationship between VA and epilepsy and to identify the characteristics of children with VA and epilepsy. Methods The records of all patients aged less than 18 years who underwent brain magnetic resonance imaging (MRI) at Pusan National University Hospital were retrospectively reviewed. Patients with isolated VA and patients with normal MRI were compared in terms of the prevalence of epilepsy. Results In total, 2,385 pediatric patients who underwent brain MRI were enrolled. Isolated VA was identified in 26 patients (VA group). Among the patients with normal MRI findings, 225 age- and sex-matched patients to the VA-group were assigned to the control group. Nine patients in the VA group (9 of 26, 34.6%) and 27 patients in the control group (26 of 225, 11.5%; P<0.001) had epilepsy. In the VA group, 20 patients (76.9%) had the VA in the cerebral hemispheres, and 6 patients (23.1%) had the VA in the brainstem and cerebellum. The latter showed a higher prevalence of epilepsy (5 of 6, 83.3%) than the former (4 of 20, 20.0%; P=0.004). Among the nine patients who had epilepsy with VA, patients whose VA involved the brainstem and cerebellum showed a significantly higher frequency of abnormal Electroencephalographic findings than patients whose VA involved the cerebral hemispheres (P=0.016). Conclusion VA, especially in the brainstem and cerebellum, might be associated with epilepsy.

Abstract
Developmental venous anomalies (DVAs), previously called venous angiomas, are the most frequently encountered cerebral vascular malformations. However, DVA is considered to be rather an extreme developmental anatomical variation of medullary veins than true malformation. DVAs are composed of dilated medullary veins converging centripetally into a large collecting venous system that drains into the superficial or deep venous system. Their etiology and mechanism are generally accepted that DVAs result from the focal arrest of the normal parenchymal vein development or occlusion of the medullary veins as a compensatory venous system. DVAs per se are benign and asymptomatic except for under certain unusual conditions. The pathomechanisms of symptomatic DVAs are divided into mechanical, flow-related causes, and idiopathic. However, in cases of DVAs associated with hemorrhage, cavernous malformations (CMs) are most often the cause rather than DVAs themselves. The coexistence of CM and DVA is common. There are some possibilities that DVA affects the formation and clinical course of CM because CM related to DVA is generally located within the drainage territory of DVA and is more aggressive than isolated CM in the literature. Brain parenchymal abnormalities surrounding DVA and cerebral varix have also been reported. These phenomena are considered to be the result of venous hypertension associated with DVAs. With the advance of diagnostic imagings, perfusion study supports this hypothesis demonstrating that some DVAs have venous congestion pattern. Although DVAs should be considered benign and clinically silent, they can have potential venous hypertension and can be vulnerable to hemodynamic changes.

Abstract
Developmental venous variations (DVVs) are anatomic variations of normal transmedullary veins which are often discovered incidentally. Although they are accepted as benign compensatory venous drainage systems, they may become symptomatic or clinically significant due to flow-related causes. The fragile venous drainage systems increase vulnerability to in-out flow alterations. Increased inflow or decreased outflow causes rise in venous pressure, which may subsequently produce ischemic symptoms. Obstruction or stenosis of the collector vein is the most common cause of decreased outflow of a DVV. However, in the absence of collecting vein stenosis, venous hypertension may still exist due to volume overload. In case of multiple DVVs with single combined drainage pathway, functional outflow restriction may occur due to diminished capability of the vessel to adapt to pressure changes. In this report, we present a case with bilateral thalamic DVVs, which cause parenchymal amorphous calcification and drain into the left internal cerebral vein. A review of the literature on DVVs with outflow restriction including pathophysiological mechanisms is also discussed.

Abstract
BACKGROUND AND PURPOSE Abnormal signal in the drainage territory of developmental venous anomalies has been well described in adults but has been incompletely investigated in children. This study was performed to evaluate the prevalence of brain parenchymal abnormalities subjacent to developmental venous anomalies in children and young adults, correlating with subject age and developmental venous anomaly morphology and location. MATERIALS AND METHODS Two hundred eighty-five patients with developmental venous anomalies identified on brain MR imaging with contrast, performed from November 2008 through November 2012, composed the study group. Data were collected for the following explanatory variables: subject demographics, developmental venous anomaly location, morphology, and associated parenchymal abnormalities. Associations between these variables and the presence of parenchymal signal abnormalities (response variable) were then determined. RESULTS Of the 285 subjects identified, 172 met inclusion criteria, and among these subjects, 193 developmental venous anomalies were identified. Twenty-six (13.5%) of the 193 developmental venous anomalies had associated signal-intensity abnormalities in their drainage territory. After excluding developmental venous anomalies with coexisting cavernous malformations, we obtained an adjusted prevalence of 21/181 (11.6%) for associated signal-intensity abnormalities in developmental venous anomalies. Signal-intensity abnormalities were independently associated with younger subject age, cavernous malformations, parenchymal atrophy, and deep venous drainage of developmental venous anomalies. CONCLUSIONS Signal-intensity abnormalities detectable by standard clinical MR images were identified in 11.6% of consecutively identified developmental venous anomalies. Signal abnormalities are more common in developmental venous anomalies with deep venous drainage, associated cavernous malformation and parenchymal atrophy, and younger subject age. The pathophysiology of these signal-intensity abnormalities remains unclear but may represent effects of delayed myelination and/or alterations in venous flow within the developmental venous anomaly drainage territory.

Abstract
Developmental venous anomaly (DVA), formally known as venous angioma, is a congenital anatomic variant of the venous drainage of the brain. Although they typically have a benign clinical course and a low symptomatic rate, thrombosis of a drainage vein may occur, leading to potentially debilitating complications. We report a unique case of spontaneous thrombosis of a posterior fossa developmental venous anomaly with cerebellar infarct in a 61-year-old man who presented with acute onset cerebellar ataxia. DVA thrombosis was well-depicted on CT and MR studies. Patient was put on anticoagulant therapy and complete recanalization was seen on follow-up imaging.

Abstract
BACKGROUND AND PURPOSE Developmental venous anomalies are the most common intracranial vascular malformation. Increased signal-intensity on T2-FLAIR images in the areas drained by developmental venous anomalies are encountered occasionally on brain imaging studies. We evaluated diffusion and perfusion MR imaging findings of the abnormally high signal intensity associated with developmental venous anomalies to describe their pathophysiologic nature. MATERIALS AND METHODS We retrospectively reviewed imaging findings of 34 subjects with signal-intensity abnormalities associated with developmental venous anomalies. All subjects underwent brain MR imaging with contrast and diffusion and perfusion MR imaging. Regions of interest were placed covering abnormally high signal intensity around developmental venous anomalies on fluid-attenuated inversion recovery imaging, and the same ROIs were drawn on the corresponding sections of the diffusion and perfusion MR imaging. We measured the apparent diffusion coefficient, relative cerebral blood volume, relative mean transit time, and time-to-peak of the signal-intensity abnormalities around developmental venous anomalies and compared them with the contralateral normal white matter. The Mann-Whitney U test was used for statistical analysis. RESULTS The means of ADC, relative cerebral blood volume, relative mean transit time, and TTP of signal-intensity abnormalities around developmental venous anomalies were calculated as follows: 0.98 ± 0.13 10(-3)mm(2)/s, 195.67 ± 102.18 mL/100 g, 16.74 ± 7.38 seconds, and 11.65 ± 7.49 seconds, respectively. The values of normal WM were as follows: 0.74 ± 0.08 10(-3)mm(2)/s for ADC, 48.53 ± 22.85 mL/100 g for relative cerebral blood volume, 12.12 ± 4.27 seconds for relative mean transit time, and 8.35 ± 3.89 seconds for TTP. All values of ADC, relative cerebral blood volume, relative mean transit time, and TTP in the signal-intensity abnormalities around developmental venous anomalies were statistically higher than those of normal WM (All P < .001, respectively). CONCLUSIONS The diffusion and perfusion MR imaging findings of the signal-intensity abnormalities associated with developmental venous anomaly suggest that the nature of the lesion is vasogenic edema with congestion and delayed perfusion.

Abstract
Background Some studies reported that cerebral developmental venous anomaly (DVA) is often concurrent with cavernous malformation (CM). But there is lack of statistical evidence and study of bulk cases. The factors associated with concurrency are still unknown. The purpose of this study was to determine the prevalence of concomitant DVA and CM using observational data on Chinese patients and analyze the factors associated with the concurrency. Methods The records of all cranial magnetic resonance imaging (MRI) performed between January 2001 and December 2012 in Beijing Tiantan Hospital were reviewed retrospectively. The DVA and CM cases were selected according to imaging reports that met diagnostic criteria. Statistical analysis was performed using the Pearson chi-square statistic for binary variables and multivariable logistic regression analysis for predictors associated with the concurrent CM. Results We reviewed a total of 165,230 cranial MR images performed during the previous 12 year period, and identified 1,839 cases that met DVA radiographic criteria. There were 205 patients who presented concomitant CM among the 1,839 DVAs. The CM prevalence in DVA cases (11.1%) was significantly higher than that in the non-DVA cases (2.3%) (P<0.01). In the multivariate analysis, we found that DVAs with three or more medullary veins in the same MRI section (adjusted OR = 2.37, 95% CI: 1.73-3.24), infratentorial DVAs (adjusted OR = 1.71, 95% CI: 1.26-2.33) and multiple DVAs (adjusted OR = 2.08, 95% CI: 1.04-4.16) have a higher likelihood of being concomitant with CM. Conclusions CM are prone to coexisting with DVA. There is a higher chance of concurrent CM with DVA when the DVA has three or more medullary veins in the same MRI scanning section, when the DVA is infratentorial, and when there are multiple DVAs. When diagnosing DVA cases, physicians should be alerted to the possibility of concurrent CM.

Abstract
We report here a rare case of focal multiple venous malformations (VMs) in the white matter, via a draining vein arising from each VM, connecting with an ipsilateral cerebral surface venous varix. The male teen was asymptomatic neurologically. A diagnostic process using of MRI/MRDSA in this extremely rare entity is important as the more incidental discovery is expected with increasing opportunities of performing brain CT/MRI for various indications.

Abstract
A spinal intradural extramedullary venous angioma is extremely rare and has not been previously reported. In this paper, the authors report on this entity with morphological and immunohistochemical evidence, and discuss the surgical strategy for its treatment. A 54-year-old woman presented to Nagoya University Hospital complaining of left-sided pain in the hip, thigh, and inguinal and perianal regions, with progressive worsening during the previous 2 weeks. Lumbar spine MRI showed an intradural extramedullary cyst at the level of T12–L1, which extended from the conus medullaris to the cauda equina. The cyst wall was not enhanced on T1-weighted MRI with Gd. Intraoperatively, a midline dural opening allowed the authors to easily visualize a dark-reddish cyst behind the spinal nerve rootlets in the cauda equina adjacent to the conus medullaris. The cyst was believed to originate from one of the spinal nerve rootlets in the cauda equina and a cluster of veins was identified on the cyst wall. The cyst was resected with the affected nerve rootlet. The surgery left no detectable neurological deficit. Based on the morphological and immunohistochemical evidence, the lesion was diagnosed as a venous angioma. No tumor recurrence was confirmed based on MRI at the time of the 2-year follow up. This is the first report of an intradural extramedullary cystic venous angioma that was successfully resected.

Abstract
BACKGROUND AND PURPOSE Association between developmental venous anomalies is well known, but remains unexplained. Our aim was to study possible hemodynamic differences around developmental venous anomalies with and without cavernous malformations. MATERIALS AND METHODS In this prospective study approved by the institutional review board, PWI was performed in 24 patients with 25 DVAs (10 with and 15 without CMs) who consented to participate. We calculated relative cerebral blood volume, relative cerebral blood flow, and relative mean transit time for the brain surrounding the DVA tributaries in reference to contralateral mirror image locations. Corresponding control values (cCBV, cCBF, and cMTT) were generated in a similar fashion for remote ipsilateral regions with normal venous drainage, also in reference to contralateral mirror image locations. Perfusion parameters for DVAs and control regions were tested for differences between groups with the t test for independent or paired samples (or the nonparametric equivalents). Similar testing was done for perfusion parameters for DVAs with and without CMs. RESULTS Normal-appearing brain surrounding DVAs showed increased rCBV (median = 2.98; range = 1.39-6.61), increased rCBF (median = 2.00, range = 0.79-4.43), and increased rMTT (mean = 1.46; 95% confidence interval, 1.32-1.59). These were significantly higher than median cCBV (0.99; 95% confidence interval, 0.89-1.06; P < .01), median cCBF (1.00; 95% confidence interval, 0.94-1.27; P < .01), and mean cMTT (1.00; 95% confidence interval, 0.98-1.02; P < .01), respectively. Mean rMTT (1.70; 95% confidence interval, 1.46-1.93) for DVAs with CMs was higher than mean rMTT (1.29; 95% confidence interval, 1.19-1.40; P < .01) for DVAs without CMs. CONCLUSIONS DVAs are strongly associated with altered hemodynamics. Significant differences in these hemodynamic alterations for DVAs with and without CMs suggest their possible role in the formation of CMs.

Abstract
BACKGROUND AND PURPOSE The risk of hemorrhage in the context of developmental venous anomaly is considered to be very low, but it has never been evaluated by susceptibility-weighted MR imaging at 3T. The goal of the present study was to evaluate the prevalence of hypointense foci (ie, microhemorrhage or cavernous malformation) associated with DVA on phase-sensitive MR imaging, on the basis of principles similar to those of susceptibility-weighted MR imaging, and to evaluate the relationship between the hypointense foci and several factors, such as white matter hyperintense lesions adjacent to DVA on T2-weighted imaging, DVA morphology, and clinical symptoms. MATERIALS AND METHODS This study retrospectively evaluated 61 lesions in 59 consecutive patients with DVA who underwent MR imaging including phase-sensitive MR imaging. Two neuroradiologists independently assessed for the presence of hypointense foci and other factors such as DVA location, depth, size, direction of draining vein on phase-sensitive MR imaging, and white matter hyperintense lesion on T2-weighted imaging. Clinical symptoms were also assessed. RESULTS Hypointense foci were observed in 62.3% (38/61) of lesions. White matter hyperintense lesion was more frequently observed in patients with hypointense foci (26/38) than in patients without hypointense foci (7/23) (P < .01). There was no significant association between hypointense foci and other factors. CONCLUSIONS Our results support the hypothesis that microhemorrhage or cavernous malformation can be related to venous congestion caused by abnormal venous drainage. We conclude that phase-sensitive MR imagingis useful for the detection of microhemorrhage or cavernous malformation in patients with DVA, especially when associated with white matter hyperintense lesion.

Abstract
OBJECTIVE We report a rare case of hydrocephalus following aqueductal stenosis caused by developmental venous anomaly (DVA). METHODS Four years after the incidental discovery of asymptomatic DVA, the 10-year-old boy presented with symptoms of hydrocephalus. Enhanced computed tomographic scans and magnetic resonance images showed supra- and infratentorial DVAs with caput medusae appearances in the right basal ganglia and cerebellum. Three dilated collector veins in the right basal ganglia, floor of the third ventricle, and floor of the fourth ventricle gathered together to drain into the great vein of Galen. Three-dimensional fusion images showed that the serpentine dilated vein from the posterior fossa coursed in the aqueduct and caused the aqueductal stenosis, which was confirmed by operative endoscopy. RESULTS Endoscopic third ventriculostomy was performed and the hydrocephalus was relieved. CONCLUSIONS Although aqueductal stenosis caused by DVA is rare, it is important to be considered in the differential diagnosis of hydrocephalus. Three-dimensional reconstruction and fusion images are very useful.

Abstract
Venous angiomas are a developmental anomaly in which embryonic venous drainage is still present into adulthood. They are usually asymptomatic and benign course but they can cause seizures and less commonly bleeding, usually associated to cavernous malformation. Normally, treatment is not necessary although bleeding, severe clinical and lesions in which it is possible a favourable approach, we can consider treatment. We show a case of a 11 years old boy with acute decrease level of consciousness. We observed hematoma in the right cerebellar hemisphere with radial tubular structures consistent with developmental venous anomaly. The hematoma was evacuated without a demonstrable other reason justifying the bleeding.

Abstract
Perfusion-CT (PCT) of the brain is a rapidly evolving imaging technique used to assess blood supply to the brain parenchyma. PCT is readily available at most imaging centers, resulting in steadily increasing use of this imaging technique. Though PCT was initially introduced and still most widely used to evaluate patients with acute ischemic stroke, a wide variety of other pathologic processes demonstrate abnormal perfusion maps. Therefore, it is important for the radiologist to recognize altered perfusion patterns observed in diseases other than typical ischemic stroke. The goal of this article is to show the perfusion maps and review the perfusion patterns observed in some subtypes of atypical stroke and in neurological entities other than stroke, so that they are recognized and not confused with the PCT patterns observed in patients with typical ischemic stroke.

Abstract
Magnetic resonance angiography (MRA) of the brain obtained at 3 T imaging has made a significant clinical impact. MRA benefits from acquisition at higher magnetic field strength because of higher available signal-to-noise ratio and improved relative background suppression due to magnetic field strength-related T1 lengthening. Parallel imaging techniques are ideally suited for high-field MRA. Many of the developments that have made 3 T MRA of the brain successful can be regarded as enabling technologies that are essential for further development of 7 T MRA, which brings additional challenges.

Abstract
With the widespread use of brain imaging studies, neurosurgeons have seen a marked increase in the number of incidental intracranial lesions, including vascular abnormalities. Specifically, the detection of incidentally discovered aneurysms, arteriovenous malformations, cavernous angiomas, developmental venous anomalies, and capillary telangiectasias has increased. The best management strategy for most of these lesions is controversial. Treatment options include observation, open surgery, endovascular procedures, and radiosurgery. Multiple factors should be taken into account when discussing treatment indications, including the natural history of the disease and the risk of the treatment. In this article, the authors focus on the natural history of these lesions and the risk of the treatment, and they give recommendations regarding the most appropriate management strategy based on the current evidence in the literature and their experience with intracranial vascular abnormalities.

Abstract
O uso de sinais ou analogias na interpretação de imagens na radiologia médica é prática comum e antiga entre os radiologistas. Comparação entre achados de imagem com animais, alimentos ou objetos se faz de modo natural. Muitos sinais são bastante específicos e em alguns casos patognomônicos. Independentemente do grau de especificidade, sinais auxiliam a prática radiológica. Vários sinais já foram descritos em neurorradiologia. Neste artigo os autores demonstrarão 15 sinais neurorradiológicos. Serão abordados as principais características de cada um, a sua importância na prática clínica e os seus achados de imagem.

Abstract
The brain vascular system develops in such a way that it continuously adapts the supply of oxygen and other nutrients to the needs of the parenchyma. To accompany the developing brain vesicles, it evolves in several steps: superficial meningeal network first; intraventricular choroid plexuses which determine the arterial pattern; penetrating capillaries from the surface to the ventricular germinal matrix forming simple transcerebral arteriovenous loops; cortical capillaries last, mainly in the last trimester. The venous return becomes connected to both the surface and to the choroidal veins, so forming distinct meningeal and subependymal venous drainage systems, while the arteries are on the surface only. While the arterial system was determined early (week 8), the venous system is continuously remodeled by the morphological changes of the base of the skull and the expansion of the brain vesicles. Until late in gestation, the vascular system is made of simple endothelial channels in which the arterial or venous fate is determined primarily by the direction of flow.

Abstract
Stenosis of a DVA may result in chronic venous ischemia. We present 6 patients (3 men, 3 women; age range, 30-79 years; mean age, 53 years) with unilateral calcification of the caudate and putamen on noncontrast CT. This calcification typically spared the anterior limb of the internal capsule. No patient presented with symptoms referable to the basal ganglia or had an underlying metabolic disorder or other process associated with calcium deposition. All patients subsequently underwent gadolinium-enhanced MR imaging and/or CTA or conventional angiography demonstrating the presence of an adjacent DVA. We hypothesize that chronic venous ischemia in the drainage territory of the DVA causes the abnormal mineralization. Greater recognition of this entity will prevent misinterpretation of this finding as acute hemorrhage and will prevent unnecessary and sometimes invasive evaluation in such patients. Furthermore, this entity should be considered in the differential diagnosis of unilateral basal ganglia hyperattenuation.

Abstract
INTRODUCTION Cerebral developmental venous anomalies (DVAs) are the most frequently encountered cerebral vascular malformation. As such, they are often observed incidentally during routine CT and MRI studies. Yet, what DVAs represent from a clinical perspective is frequently not common knowledge and DVAs, therefore, still generate uncertainty and concern amongst physicians. This article reviews our current understanding of developmental venous anomalies. RESULTS In the majority of cases, DVAs follow a benign clinical course. On rare occasions, DVAs become symptomatic generally due to an underlying associated vascular malformation such as cavernous malformations or thrombosis of the collecting vein. Rare forms of DVAs include arterialized DVAs and DVAs involved in the drainage of sinus pericranii, which warrant additional investigation by digital subtraction angiography. Cerebral abnormalities such as atrophy, white matter lesions and calcifications within the drainage territory of asymptomatic DVAs, are often identified on CT or MR imaging studies and likely represent secondary changes due to venous hypertension. There is increasing evidence that DVAs have a propensity for developing venous hypertension, which is thought to be the cause of associated cavernous malformations and parenchymal abnormalities. CONCLUSIONS DVAs represent variations of the normal cerebral venous angioarchitecture and by enlargement follow an uneventful clinical course. Complications can, however, occur and their management requires a thorough understanding of the nature of DVAs, including their frequent coexistence with other types of vascular malformation, and the existence of more complex but rare forms of presentation, such as the arterialized DVAs.

Developmental venous anomalies: appearance on whole-brain CT digital subtraction angiography and CT perfusion. Neuroradiology 2010; 53:331-41. [PMID: 20652805 PMCID: PMC3077751 DOI: 10.1007/s00234-010-0739-9] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2010] [Accepted: 06/23/2010] [Indexed: 12/02/2022]
Abstract
Introduction Developmental venous anomalies (DVA) consist of dilated intramedullary veins that converge into a large collecting vein. The appearance of these anomalies was evaluated on whole-brain computed tomography (CT) digital subtraction angiography (DSA) and CT perfusion (CTP) studies. Methods CT data sets of ten anonymized patients were retrospectively analyzed. Five patients had evidence of DVA and five age- and sex-matched controls were without known neurovascular abnormalities. CT angiograms, CT arterial-venous views, 4-D CT DSA and CTP maps were acquired on a dynamic volume imaging protocol on a 320-detector row CT scanner. Whole-brain CTP parameters were evaluated for cerebral blood flow (CBF), cerebral blood volume (CBV), time to peak (TTP), mean transit time (MTT), and delay. DSA was utilized to visualize DVA anatomy. Radiation dose was recorded from the scanner console. Results Increased CTP values were present in the DVA relative to the unaffected contralateral hemisphere of 48%, 32%, and 26%; and for the control group with matched hemispheric comparisons of 2%, −10%, and 9% for CBF, CBV, and MTT, respectively. Average effective radiation dose was 4.4 mSv. Conclusion Whole-brain DSA and CTP imaging can demonstrate a characteristic appearance of altered DVA hemodynamic parameters and capture the anomalies in superior cortices of the cerebrum and the cerebellum. Future research may identify the rare subsets of patients at increased risk of adverse outcomes secondary to the altered hemodynamics to facilitate tailored imaging surveillance and application of appropriate preventive therapeutic measures.
