A 51-year-old man without notable medical history presented with acute onset of left-sided weakness in the arm, facial palsy, and dysarthria. The symptoms lasted for 15 minutes before apparent recovery. The neurological examination revealed effacement of the nasolabial fold without any other focal deficits. Blood pressure, electrocardiographic results, and cardiac monitoring findings were normal. Computed tomography (CT) showed hypodense areas in the vascular territory of the right medial cerebral artery, indicating cerebral infarctions. These findings were confirmed by subsequent magnetic resonance imaging denoting diffusion restriction to the corresponding areas with a high T2 signal, swelling, and subtle cortical enhancement. Additional CT angiography (CTA) showed a small focal irregularity on the posterior wall of the right carotid bulb, suspicious for a carotid web (CW) (Figure 1).
