These foreign objects can present at various points post-surgery, with symptoms appearing anywhere from the early recovery phase to decades after the procedure. This uncommon complication often mimics the appearance of a tumor or mass, creating diagnostic difficulties and a higher risk for further complications.

A previously healthy 55-year-old female patient presented with an epileptic attack. The physical examination was unremarkable. Computed tomography showed multiple frontal lobe calcifications. Digital subtraction angiography revealed an isolated SSS DAVF fed by the bilateral middle meningeal and superficial temporal arteries and the right anterior cerebral artery, with cortical venous drainage (Cognard III classification). Endovascular treatment was performed as follows. Initially, the microcatheter was navigated through the left middle meningeal artery and across the sinus wall defect to access the isolated SSS segment, which was subsequently packed by coiling. Thereafter, transarterial embolization by Onyx casting via the bilateral middle meningeal arteries was conducted to achieve nearly complete obliteration of the isolated SSS DAVF. The postoperative course was unremarkable, with no new neurological deficits. Six-month follow-up angiography confirmed the resolution of the DAVF without epileptic events.
