Introduction: Dural arteriovenous fistula (DAVF) is a vascular malformation. Although rare, DAVFs can represent a potentially reversible cause of dementia. Bilateral white matter changes can be detected on the magnetic resonance imaging of patients with DAVFs. Familiarity with symptoms of DAVFs can reduce the incidence of misdiagnosis of dementia syndrome. This study aimed to explore the clinical manifestation, imaging characteristics, and prognosis of dementia with bilateral white matter changes caused by DAVFs. Case Report: A 56-year-old man presented with memory deterioration, tinnitus, and weakness in both lower limbs for over 2 months. Magnetic resonance imaging of the brain revealed white matter signal changes in the bilateral ventricles and centrum semiovale, which manifested as low signal on T1-weighted imaging, high signal on T2-weighted imaging, fluid-attenuated inversion recovery, and diffusion-weighted imaging. Digital subtraction angiography revealed DAVFs along the lateral sinus. The patients’ condition improved significantly after endovascular embolization of the DAVFs. Conclusions: DAVFs presenting with dementia are rare and cases with bilateral white matter alterations can be easily misdiagnosed as other diseases. If the patient has dementia and bilateral alterations in the white matter, a DAVF should be considered. This type of dementia is reversible and may be associated with venous hypertension caused by arteriovenous fistulas. Early digital subtraction angiography is important to reduce misdiagnoses.

Progress in research on intracranial multipleï¿½duralï¿½arteriovenous fistulas (Review)

Intracranial multiple dural arteriovenous fistulas (MDAVFs) are rare lesions that are difficult to treat. The key factors involved in the development of MDAVFs remain unknown. At present, the majority of reports on intracranial MDAVFs are confined to case reports and small case series, and thus understanding of MDAVFs is limited. The current review assesses the available literature to date with the aim of reviewing the progress in research on intracranial MDAVFs. Intracranial MDAVFs may be divided into two types: Synchronous and metachronous. While the exact pathogenesis of MDAVFs is unknown, a number of possible mechanisms are considered relevant. The first is that MDAVFs develop following recanalization of a large sinus thrombosis that involves several sinuses. The second possibility is that a pre-existing DAVF may induce sinus thrombosis or venous hypertension, resulting in a new MDAVF. The third is that MDAVFs are caused by increased angiogenic activity, which may induce the development of MDAVFs. Intracranial MDAVFs have a malignant clinical course, and their symptoms generally rapidly progress following onset. It is therefore important to identify intracranial MDAVFs at an early stage. A number of imaging technologies, including computed tomography (CT), magnetic resonance imaging (MRI), digital subtraction angiography (DSA) and single-photon emission computed tomography (SPECT), may be used to detect MDAVFs. Of these, CT and MRI provide information on brain morphology, SPECT provides brain blood flow information, and DSA is the gold standard that may be used to identify angioarchitecture and hemodynamics. MDAVFs require timely and aggressive treatment, which may include endovascular embolization, surgical resection, radiosurgery and conservative treatment, and in some cases, combined treatments are required. Appropriate and aggressive treatment regimens can markedly improve neurological deficits and cognitive function in patients with MDAVFs.

Resumen: Los casos clínicos son un género propio de las comunidades de profesionales de la salud que se basa en la experiencia clínica de uno o unos pocos pacientes. A diferencia de otros autores, consideramos que tienen una naturaleza principalmente narrativa y que, por lo tanto, se pueden caracterizar por una estructuración en los cinco apartados canónicos de la narración: situación inicial, nudo, (re)acción o evaluación, desenlace y situación final. Verificamos la presencia de estos componentes en un caso clínico prototípico del campo de la neurología, comparándolos con sus análogos en textos provenientes del género reconocidamente narrativo de los cuentos clínicos.Abstract: Clinical case reports are a genre developed within the communities of healthcare professionals and based on the clinical experience of one or a few patients. Unlike other authors, we consider that they have a mainly narrative nature and, therefore, can be characterized by a structure following the five canonical sections of the narrative: initial situation, node, (re) action or evaluation, denouement and final situation. We verify the presence of these components in a prototypical clinical case report from the field of neurology, comparing them with analogous samples of another genre that is widely recognised as narrative: clinical tales.
