RESUMEN
The optimal endovascular management of high-grade dural arterial-venous fistulae (dAVF) can be technically challenging in cases where the involved venous sinus segment is inaccessible through the traditional percutaneous approach. In this report, we describe our experience with the transcranial endovascular approach for the treatment of a high-grade dAVF. We also provide a literature review of other reports of transcranial endovascular dAVF embolization. We propose that transcranial endovascular embolization of high-grade dAVF appears to be safe and effective in cases where the fistula is inaccessible to percutaneous routes alone.
RESUMEN
In this report, we share the case of a 65-year-old male with a remote history of brain concussion who presented to the emergency department for evaluation of transient amnesia that lasted 30 minutes to one hour. He was found to have spontaneous intracerebral hemorrhage of the fornix as a cause of his amnesic episode. To date from the creation of this case report (January 2023), spontaneous hemorrhage of the fornix resulting in transient amnesia has not been previously described in the literature. The fornix is an unusual location for spontaneous hemorrhage to occur. The differential diagnosis of transient amnesia is broad and includes, but is not limited to, transient global amnesia, traumatic injury, hippocampal infraction, and various metabolic derangements. Determination of the etiology of transient amnesia can result in changes in treatment decisions. Because of this unique patient presentation, we propose that spontaneous hemorrhage of the fornix should be considered in patients who present with transient amnesia.
RESUMEN
The causes of syncope are diverse and extensive; carotid body tumors are an extremely rare cause of syncope. These rare neoplasms represent less than 0.5% of all head and neck tumors. The authors present a case of a woman with syncope who was found to have a right-sided carotid body tumor. After surgical resection was performed, she did not have any additional syncopal or near-syncopal events. The authors provide a review of the literature on the natural history, presentation, and preferred management of carotid body tumors. With modern diagnostic tools and treatment options, most patients with this diagnosis can expect to recover fully.

Moyamoya disease is a chronic, progressive occlusion of the circle of Willis arteries that leads to the development of characteristic collateral vessels seen on imaging, particularly cerebral angiography. The disease may develop in children and adults, but the clinical features differ. Moyamoya disease occurs predominantly in Japanese individuals but has been found in all races with varying age distributions and clinical manifestations. As a result, moyamoya disease has been underrecognized as a cause of ischemic and hemorrhagic strokes in Western countries. At this time, there is no known cure, and existing treatment options are controversial. The authors describe the case of a 44-year-old African American woman with a history of hypertension, cervical cancer, breast cancer, and stroke who was diagnosed as having moyamoya disease. A review of the literature for the various facets of this condition is also provided.
