“…Pulsatile exophthalmos may result from other causes, such as traumatic and nontraumatic CCF,1718 aortic regurgitation,19 intracranial20 and intraosseous21 arteriovenous malformations, and sphenoid wing dysplasia with temporal lobe herniation in neurofibromatosis 22. A CT angiogram, as performed in one of our patients, can be obtained to rule out CCF.…”

Traumatic orbital roof fractures are rare and are managed nonoperatively in most cases. They are typically associated with severe mechanisms of injury and may be associated with significant neurologic or ophthalmologic compromise including traumatic brain injury and vision loss. Rarely, traumatic encephalocele or pulsatile exophthalmos may be present at the time of injury or develop in delayed fashion, necessitating close observation of these patients. In this article, we describe two patients with minimally displaced blow-in type orbital roof fractures that were later complicated by orbital encephalocele and pulsatile exophthalmos, prompting urgent surgical intervention. We also suggest a management algorithm for adult patients with orbital roof fractures, emphasizing careful observation and interdisciplinary management involving plastic surgery, neurosurgery, and ophthalmology.

“…We assume that AVFs mostly develop in the dura mater because it is comprised of vascular-rich tissues and possibly susceptible to infection and/or inflammation, which triggers thrombosis and the angiogenesis of vasculatures within it, inducing the formation of an AVF. Osseous AVFs, except for AC-AVFs, have been reported in other locations: the posterior condylar vein, [44][45][46] the diploic vein in the parietal bone, 47) within the sphenoidal bone, [48][49][50] the petrous bone, 14,51) and occipital bone. 14,52) Authors of previous studies assumed that these osseous lesions are acquired lesions and that thrombosis in the osseous vein induced by paranasal sinus inflammation or the skull base infective process trigger the formation of the osseous AVF, 48) which is consistent with our theory.…”

The anterior condylar arteriovenous fistula (AC-AVF) is a relatively rare AVF that affects the vasculatures adjacent to the hypoglossal canal. We aimed to discuss the etiology and definition of the AC-AVF from the viewpoint of the osseous venous anatomy. Our recent study, which used modern imaging technology (CT digital subtraction venography and cone beam CT reconstructed from 3D rotational angiography), elucidated the intraosseous venous anatomy in this region and the precise fistulous locations of AC-AVFs. Those findings suggest that the AC-AVF is a group of "osseous" AVF that involves the anterior condylar vein and jugular tubercle venous complex (JTVC), and the osseous veins connected to them. The AC-AVF develops in osseous veins adjacent to the hypoglossal canal, and it is one of the most common subtypes of osseous AVFs. The angioarchitectures and etiology of AC-AVFs discussed herein are essential to understand this clinical entity.

“…Transvenous endovascular approaches have been described to treat intraosseous AVF. [ 10 ] In this case, the decision of taking the transvenous approach was because of the convergence of multiple feeders from different arteries into the venous sac. In the present case, obliteration of AVF was achieved with minimal use of a long and wide coil (ED coil ∞; Kaneka Medics, Osaka, Japan).…”

Background: Intraosseous arteriovenous fistula (AVF) is a rare clinical entity that typically presents with symptoms from their effect on surrounding structures. Here, we report a case of intraosseous AVF in the sphenoid bone that presented with bilateral abducens palsy. Case Description: A previously healthy man presented with tinnitus for 1 month, and initial imaging suspected dural AVF of the cavernous sinus. Four-dimensional digital subtraction angiography (4D-DSA) imaging and a three-dimensional (3D) fused image from the bilateral external carotid arteries revealed that the shunt was in a large venous pouch within the sphenoid bone that was treated through transvenous coil embolization. His symptoms improved the day after surgery. Conclusion: This is a case presentation of intraosseous AVF in the sphenoid bone and highlights the importance of 4D-DSA and 3D fused images for planning the treatment strategy.
