Intracranial dural arteriovenous fistula (DAVF) with perimedullary venous drainage may cause brainstem swelling and represent a diagnostic challenge. A 66-year-old man presented to the emergency room with recurrent vertigo, minimal truncal ataxia with a wide-based gait, and a slightly impaired tandem gait. Brain magnetic resonance imaging (MRI) revealed a hyperintense lesion in the left pontomedullary area on T2-weighted images (T2WIs) with partial gadolinium enhancement, but without increased signals on diffusion-weighted images.

Goal: Sporadic brain cavernous malformations commonly correlate with developmental venous anomalies; however, developmental venous anomalies may exist without cavernous malformations. Infratentorial location and specific angioarchitectural features of the developmental venous anomaly increase the odds of a concomitant malformation. Animal data also suggest chronic inflammatory disease, oxidative stress, and angiogenesis promote cavernous malformation development. Read More

Multi-factorial causes jeopardize brain integrity in β-thalassaemia. Intracranial parenchymal and vascular changes have been reported among young β-thalassaemia patients but conventional magnetic resonance imaging (MRI) findings are contradictory making early MRI and magnetic resonance angiography (MRA)/venography monitoring a matter of debate. This study prospectively investigated 75 neurologically asymptomatic β-thalassaemia patients (mean-age 35·2 ± 10·7 years; 52/75 transfusion-dependent; 41/75 splenectomised) using a 3T magnetic resonance scanner; clinical, laboratory and treatment data were also collected.

Background: Indocyanine green videoangiography (ICG-V) is used with increasing frequency in neurovascular surgery. ICG-V use in spinal dural arteriovenous fistulas (DAVFs) allows visualization of the hemodynamics of the fistula and to confirm its exclusion after ligation of the feeder. Here, we illustrate how ICG-V is useful for centering the surgical exposure during mini-invasive approaches to spinal DAVFs. Read More

Traumatic carotid cavernous fistula(CCF)is known to present a direct connection between the cavernous segment of the internal carotid artery(ICA)and the cavernous sinus(CS). In rare cases, the fistula is formed between the intradural internal carotid artery(ICA)and the cavernous sinus(CS)via a pseudoaneurysm(pAN), requiring appropriate management and aggressive surgical treatment. We describe a 58-year-old man who sustained a severe head injury diagnosed as traumatic CCF treated with an intradural pAN procedure and transarterial coil embolization combined with a Low-profile Visualized Intraluminal Support(LVIS)stent.

Congenital cerebrovascular anomalies in the pediatric age group are myriad with diverse etiologies. The purpose of this paper is to provide an imaging overview of congenital vascular malformations and vascular tumors, as these conditions are varied and the characteristic vascular abnormality may even suggest the underlying systemic condition in helping to guide further management. For example, the identification of an arterial anomaly such as agenesis/hypoplasia/duplication may warrant further evaluation for an associated syndrome. Read More

Pulmonary arteriovenous malformations (PAVMs) are rare, abnormal low resistance vascular structures that connect a pulmonary artery to a pulmonary vein, thereby bypassing the normal pulmonary capillary bed and resulting in an intrapulmonary right-to-left shunt. The spectrum of PAVMs extends from microscopic lesions causing profound hypoxemia and ground glass appearance on computed tomography (CT) but with normal catheter angiographic findings to classic pulmonary aneurysmal connections that abnormally connect pulmonary veins and arteries. These malformations most commonly are seen in hereditary hemorrhagic telangiectasia (HHT). Read More

Background: Brainstem cavernous malformations represent around 8%-22% of all intracranial cavernous malformations but exhibit a higher annual incidence of hemorrhage (2%-3%) compared with other cavernous angiomas and tend to be more symptomatic given their proximity to critical nuclei and fiber tracts. Recently, endoscopic endonasal techniques have been used for the removal of ventral skull base lesions, with significant improvement in operative morbidity and mortality compared with open approaches. Here we demonstrate the utility and feasibility of the endoscopic transclival approach for ventrally located pontine cavernomas in carefully selected patients. Read More

Arachnoid granulations are common incidentally detected small dural lesions which are usually asymptomatic and follow cerebrospinal fluid density/signal intensity on CT/MRI. Such lesions reaching a size of more than 1 cm are termed as giant arachnoid granulations (GAGs) which have been previously reported to cause venous hypertension and headaches. We report a case of GAG involving the proximal half of the superior sagittal sinus in a 45-year-old male patient which was associated with left temporal thrombosed dural arteriovenous fistula (AVF) whose thrombosed draining veins were seen converging towards the site of GAG.

Background: A carotid cavernous fistula is a rare type of arteriovenous (AV) fistula due to an abnormal communication between the cavernous sinus and the carotid arterial system. Normal venous return to the cavernous sinus is impeded as high-pressure arterial blood enters the cavernous sinus.

Purpose: To report percutaneous transcranial puncture, embolization and occlusion of a very symptomatic hypoglossal canal/anterior condylar vein dural arteriovenous fistula (DAVF) using syngo iGuide navigational software in a patient in whom transarterial and transvenous embolization and surgery had failed.

Methods: After unsuccessful arterial and venous embolization and surgical treatment of a symptomatic hypoglossal canal DAVF, a 47-year-old man was transferred for further management. With exquisite anatomic detail provided by C-arm cone-beam computed tomography (CBCT) equipment (Artis zee Biplane, Dyna CT VC21H, Siemens Healthcare GmbH, Germany) and syngo iGuide needle guidance navigational software (Siemens Healthcare GmbHy) for planning a safe direct approach, the hypoglossal/anterior condylar vein, the dominant outflow vein of the fistula, was needle punctured percutaneously at the hypoglossal foramen and occluded with ethylene vinyl alcohol copolymer liquid embolic agent (Onyx, Medtronic, Minneapolis, Minnesota, USA) after placing two anchoring platinum coils (Target detachable coils, Stryker Neurovascular, Fremont, California, USA).

Cortical venous drainage (CVD) increases the probability of intracranial hemorrhage and mortality rate of dural arteriovenous fistulas (DAVF). Although digital subtraction angiography (DSA) is the most accurate method to determine CVD in DAVFs, this modality has limitations due to its invasive nature and radiation issues. The purpose of this study was to evaluate the diagnostic utility of arterial spin-labeling perfusion-weighted images (ASL-PWI) to identify CVD in patients with DAVF. Read More
