Abstract BACKGROUND AND IMPORTANCE: We report a rare case of diffusion restriction caused by venous hypertension resulting from a dural arteriovenous fistula (DAVF) that completely reversed after successful embolization. CLINICAL PRESENTATION: A 54-year-old man presented with symptoms secondary to a DAVF. Magnetic resonance imaging (MRI) revealed left parieto-temporo-occipital diffusion restriction. The angiogram revealed a Cognard type III left lateral tentorial DAVF resulting in severe venous hypertension. Transarterial Onyx embolization was performed, resulting in angiographic cure of the fistula with normalization of the venous drainage in the left parieto-temporo-occipital region. A follow-up MRI examination performed 4 weeks after the embolization revealed resolution of the previously seen area of restricted diffusion. CONCLUSION: It is important to consider the possibility of diffusion restriction reversal, because misdiagnosis or the false assumption that irreversible cerebral infarction has occurred may inappropriately alter or delay the treatment of these aggressive lesions.

Progressive Weakness

We report a rare case of jugular foramen dural arteriovenous fistula (DAVF) with spinal venous drainage. A 48-year-old woman suffered from progressive weakness of lower extremities and incontinence of urine and feces for 14 days. Magnetic resonance imaging (MRI) revealed a tortuous posterior medullary vein at C2–T2 and ischemic signal at C2–C4 of the spinal cord. Brain MRI revealed an abnormal high signal near the left jugular foramen. Digital subtraction angiography of the spinal vascular was negative, while brain angiography showed a left jugular foramen DAVF with spinal perimedullary venous drainage. The patient recovered completely soon after endovascular embolization with Onyx-18. Diagnosis of a DAVF presenting with myelopathy is challenging. Early diagnosis and treatment are essential for a favorable outcome.

A 71-year-old woman presented with headache and dilated vessels on CTA. Angiography demonstrated a complex dural arteriovenous fistula with retrograde cortical venous hypertension, supplied by branches of internal and external carotids bilaterally into a fistulous pouch paralleling the left transverse and sigmoid sinuses, which was occluded at the jugular bulb. The patient refused treatment and was lost to follow-up, returning with sudden confusion and hemianopsia from left temporo-occipital hemorrhage. Transvenous endovascular embolization was performed using the dual-microcatheter technique with a combination of coiling and Onyx copolymer, completely occluding the sinus and fistula while preserving normal venous drainage.The video can be found here: http://youtu.be/u_4Oc7tSmDM.

A case of type V intracranial dural arteriovenous fistula (DAVF) is reported because of its unusual rapidly progressive paraparesis. Despite this clinical presentation, the diagnosis of DAVF was made and precocious endovascular treatment was instituted. Angiographic normalization was obtained after embolisation and the patient significantly improved within the first weeks, although at the six month control MRI there still was a hyperintense signal of the cord in T2 weighted images, but less extensive than originally.

Background and purpose We present a case of magnetic resonance imaging (MRI)-occult intracranial dural arteriovenous fistula (DAVF) with serious cervical myelopathy and review the pathophysiological background. Summary of case A 61-year-old man had suffered from progressive neurological deterioration. He had demonstrated swollen spinal cord with diffuse enhancement and no dilated vascularity on MRI. Finally, digital subtraction angiography revealed DAVF at the petrous ridge and it was successfully treated by embolization. Conclusion A slow flow DAVF is not readily recognizable on MRI. Whenever a patient presents with unexplainable progressive myelopathy, a possibility of vascular origin has to be considered.

Prompt Diagnosis

Abstract BACKGROUND AND IMPORTANCE: Prompt diagnosis of intracranial dural arteriovenous shunt (DAVS) with spinal venous drainage, classified as Cognard type V, is difficult. We investigated the angiographic and magnetic resonance imaging (MRI) characteristics of Cognard type V DAVS to determine the reason for the difficulty in early diagnosis. CLINICAL PRESENTATION: We systematically reviewed 54 published and 3 new cases of Cognard type V DAVS. The pattern of venous drainage was classified on the basis of relative dominance of the anterior and posterior spinal veins with the use of angiograms. T2-weighted sagittal MRIs were used to detect signal flow voids of enlarged spinal veins. Types of venous drainage were determined in 49 of the 57 cases. Twenty-eight and 8 cases showed a dominance of anterior and posterior spinal venous drainage, respectively. In 13 cases, venous drainage was equally distributed through the anterior and posterior spinal veins. Of 41 cases with an abnormally dilated anterior spinal vein, MRIs were available for 25 cases. Signal flow voids of enlarged anterior spinal veins were detected in 9 cases (36.0%), whereas dilatation of the posterior spinal veins was apparent in 9 of 16 cases (56.3%). Overall, MRI detected enlargement of either anterior or posterior spinal veins in 15 of 41 cases (36.6%). CONCLUSION: In Cognard type V DAVS, anterior venous drainage is dominant. Because the anterior spinal veins are located subpially, flow voids are less prominent on sagittal T2-weighted MRI. This may lead to difficulties in diagnosing. Evaluation with MR angiography may compensate for these limitations.

We report the endovascular treatment of a 40-year-old woman with bilaterally thrombosed transverse sinuses and a dural arteriovenous fistula (DAVF) causing cortical venous reflux by recanalization, angioplasty and stent deployment of the occluded sinus segment followed by occlusion of the DAVF by stent deployment in the fistulous segment. By recanalization of the occluded sinus we re-established normal anterograde venous drainage and eliminated the venous hypertension and cortical venous reflux. After the procedure, the patient was treated with aspirin and clopidogrel for three months. A follow-up examination showed total occlusion of the DAVF, patency of the sinus and a complete resolution of the clinical symptoms.

Spinal Dural Arteriovenous Fistulas

We describe a unique case of bilateral cervical spinal dural arteriovenous fistulas mimicking an intracranial dural arteriovenous fistula near the foramen magnum. We review its detection via MRI and digital subtraction angiography and subsequent management through surgical intervention. Pitfalls in diagnostic angiography are discussed with reference to accurate location of the fistula site. The venous anastomotic connections of the posterior midline spinal vein to the medial posterior medullary vein, posterior fossa bridging veins, and dural venous sinuses of the skull base are discussed with reference to problem-solving in this complex case. The mechanism of myelopathy through venous hypertension produced by spinal dural fistulas is also emphasized.

Abstract OBJECTIVE To describe the use of perfusion computed tomography (PCT) in the study of hemodynamic disturbances associated with a case of a cerebral dural arteriovenous fistula (DAVF) with leptomeningeal venous drainage presenting with focal signs. CLINICAL PRESENTATION A 79-year-old man presented because of loss of strength in the right arm. On examination, he presented mild right-side hemiparesis. Magnetic resonance imaging showed the presence of a left frontoparietal hyperintense lesion on T2-weighted images. Magnetic resonance angiography and digital substraction angiography (DSA) showed a convexity Borden type III DAVF. The DAVF was embolized with bucrylate, and control DSA showed complete obliteration of the malformation. The patient improved from his clinical presentation and 6 months after treatment was asymptomatic. TECHNIQUE Perfusion computed tomography was performed before and after treatment. All imaging studies were performed on a 6-slice spiral computed tomography scanner. Each series studied a 2.4-cm slide of brain at the level of the cerebral convexity where the DAVF was located. Quantitative perfusion data were obtained from significant regions of interest of both hemispheres, and an interhemispheric ratio (IR) was calculated. Pretreatment PCT showed an increase in mean transient time (IR = 2.2) and time to peak (IR = 1.15), with an increase in cerebral blood volume (IR = 1.9) in the left frontal areas related to a similar area in the contralateral hemisphere. Six months after treatment, perfusion maps did not show any interhemispheric difference. CONCLUSION Perfusion computed tomography could help to identify the hemodynamic disturbances associated with DAVFs with leptomeningeal venous drainage.

Tentorial Sinus

Cranial dural arteriovenous fistula (cDAVF) may rarely lead to parkinsonism and rapid cognitive decline. Dysfunction of the extrapyramidal system and the thalamus, due to venous congestion of the Galenic system with subsequent parenchymal edema, is likely to represent an important pathophysiological mechanism. Here, we report a case of a 57-year-old man with a cDAVF of the straight sinus (Borden type III; DES-Zurich bridging vein shunt [BVS] type with direct, exclusive, and strained leptomeningeal venous drainage [LVD]) and subsequent edema of both thalami, the internal capsule, the hippocampi, the pallidum, and the mesencephalon. Several attempts at venous embolization were unsuccessful, and the neurological condition of the patient further deteriorated with progressive parkinsonism and intermittent episodes of loss of consciousness (KPS 30). A suboccipital mini-craniotomy was performed and the culminal vein was disconnected from the medial tentorial sinus, achieving an immediate fistula occlusion. Three-month follow-up MRI revealed complete regression of the edema. Clinically, parkinsonism remitted completely, allowing for tapering of dopaminergic medication. His cognition markedly improved in further course. The purpose of this report is to highlight the importance of rapid and complete cDAVF occlusion to reverse venous hypertension and prevent progressive clinical impairment. The review of the literature underlines the high morbidity and mortality of these patients. Microsurgical disconnection of the fistula plays an important role in the management of these patients and, surprisingly, has not been reported so far.
