F Heran Dreyfus, O Galatoire, P Koskas, F Lafitte, E Nau, O Bergès
Orbito-palpebral vascular pathology represents 10% of all the diseases of this area. The lesion may be discovered during a brain CT scan or MRI, or because it causes clinical symptoms such as orbital mass, visual or oculomotor alteration, pain, proptosis, or acute bleeding due to a complication of the lesion (hemorrhage, thrombosis). We present these lesions using an anatomical, clinical, imaging and therapeutic approach. We distinguish four different entities. Vascular tumors have common imaging characteristics (hypersignal on T2 sequence, contrast enhancement, abnormal vascularization well depicted with ultrasound and Doppler, and possible bleeding)...

OBJECTIVES: Time-of-arrival (TOA) maps can be derived from high-resolution 4-dimensional (4D) contrast-enhanced magnetic resonance angiography (MRA) data sets to provide a quantitative description of contrast material arrival time in each voxel. This information can further be processed to create a compressed time evolution curve that virtually shortens the contrast bolus (virtual bolus [VB]). The purpose of this project was to determine whether TOA-enhanced 4D MRA and/or VB imaging improve the display of contrast kinetics in patients with vascular disease...

BACKGROUND: Hair collar sign (HCS) and hair tuft of the scalp (HTS) are cutaneous signs of an underlying neuroectodermal defect, but most available data are based on case reports. OBJECTIVE: We sought to define the clinical spectrum of HCS and HTS, clarify the risk for underlying neurovascular anomalies, and provide imaging recommendations. METHODS: A 10-year multicenter retrospective and prospective analysis of clinical, radiologic, and histopathologic features of HCS and HTS in pediatric patients was performed...

Arteriovenous malformation (AVM) of the head and neck is a rare and potentially life threatening entity due to massive haemorrhage. There are several indications for treatment, including age of the patient and location, extent and type of vascular malformation. Endovascular therapy can effectively cure most lesions with limited tissue involvement. Surgery can be used in selected cases in combination with embolization. Here we report the case of a young woman affected by a massive AVM on the left side of the mandible and submandibular region, and also review the literature on AVM with special attention to treatment strategies...

Aim of the Study mTOR inhibitors are showing promising results in the management of vascular anomalies. Although current controlled trials remain to be completed, many individual experiences are being published. We present our series of children with complex vascular anomalies treated with sirolimus. Patients and Methods A retrospective review of 41 patients treated with sirolimus between January 2011 and December 2015 was performed: 15% (n = 6) had vascular tumors (4 kaposiform hemangioendotheliomas, 1 PTEN) and 85% (n = 35) had malformations (13 generalized lymphatic anomalies/Gorham-Stout diseases [GSD], 1 kaposiform lymphangiomatosis [KLA], 11 large lymphatic malformations (LMs) in critical areas, 2 lymphedemas, 4 venous malformations, and 4 aggressive arteriovenous malformations [AVM])...

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...

In 1976 an infant boy initially presented with a choroidal vein of Galen malformation (cVOGM). Craniotomy and clipping of the anterior cerebral artery and posterior choroidal arteries was performed, which was reported in the literature 40 years ago. The patient remained asymptomatic until age 42 when he re-presented with an isolated intraventricular hemorrhage. Angiography demonstrated cVOGM with venous sinus occlusive disease leading to venous hypertension and subsequent intraventricular hemorrhage. The angiogram also demonstrated a 'pseudo-nidus' composed of multiple arterial-to-arterial anastomoses that had developed as a result of the original surgical treatment...

Arteriovenous malformation (AVM) is a structural vascular abnormality in which the arterial vasculature connects with the venous vasculature without capillary connections. AVM confined to the nasal cavity is considerably rare. Blurred vision can be one of the associated symptoms. A combined approach of complete surgical resection with prior superselective embolization is the treatment of choice. Following resection, the reconstruction of facial defects, particularly in the nasal area, is challenging. The present study reports the rare case of a patient with an AVM in the nasal cavity, in which embolization, resection and flap reconstruction were performed...

BACKGROUND: We aimed to improve management of extremity low-flow vascular malformations by analyzing the histology and imaging of venous malformations (VMs) not responsive to sclerotherapy. METHOD: We reviewed patient records of 102 consecutive patients treated with sclerotherapy for extremity VM in our institution to identify patients who had undergone surgery due to insufficient response. We semi-quantitatively analysed the tissue specimens and compared histological findings to those in preoperative imaging...

BACKGROUND: Traditional digital subtraction angiography (DSA) is currently the gold standard diagnostic method for the diagnosis and evaluation of cerebral arteriovenous malformation (AVM) and dural arteriovenous fistulas (dAVF). OBJECTIVES: The aim of this study was to analyze different less invasive magnetic resonance angiography (MRA) images, time-resolved MRA (TR-MRA) and three-dimensional time-of-flight MRA (3D TOF MRA) to identify their diagnostic accuracy and to determine which approach is most similar to DSA...

BACKGROUND: Arteriovenous Malformations (AVMs) are hypothesized to be static, congenital lesions developing as early as 4 weeks of fetal life. New literature has shown that AVMs may represent dynamic and reactive vascular lesions arising from cerebral infarction, inflammation, or trauma. A literature search reveals 17 previously reported cases of new AVM formation after previous negative imaging studies. This reactive development or "second hit" theory suggests that at a molecular level, growth factors may play a vital role in aberrant angiogenesis and maturation of an arterio-venous fistula into an AVM...

OBJECTIVES: To determine the basic biochemical features of microparticles (MP) in patients with venous malformation (VM) of the head and neck. METHODS: MP were isolated from peripheral venous blood of VM patients or healthy subjects and from lesional fluid of VM patients. Flow cytometry and real-time polymerase chain reaction were employed to determine the concentration, cellular origin and RNA expression of obtained MP. A functional coagulation test was applied to measure the coagulant activity of MP...

OBJECTIVE The goal of stereotactic radiosurgery (SRS) for arteriovenous malformation (AVM) is complete nidus obliteration, thereby eliminating the risk of future hemorrhage. This outcome can be observed within the first 18 months, although documentation of AVM obliteration can extend to as much as 5 years after SRS is performed. A shorter time to obliteration may impact the frequency and effect of post-SRS complications and latency hemorrhage. The authors' goal in the present study was to determine predictors of early obliteration (18 months or less) following SRS for cerebral AVM...

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...
