From: Inactivated COVID-19 vaccine induced acute stroke-like focal neurologic symptoms: a case series
Vascular imaging features in patients with focal neurological symptoms after inactivated COVID-19 vaccination. Panel A-C, time-of-flight (TOF) magnetic resonance angiography (MRA) of the brain shows multifocal luminal irregularity and narrowing of bilateral posterior cerebral arteries (A) and subsequent imaging show reversion of the narrowing on day 3 (B) and day 28 (C). Panel D-F, TOF-MRA show multifocal narrowing of M3 segment of right middle cerebral artery (MCA) and focal narrowing of A3 segment of right anterior cerebral artery on day 0 (D) and later reversion on day 3 (E) and day 14 (F). Panel G-I, computed tomography angiography (CTA) of the brain shows focal narrowing of M2 segment of left MCA (G) and subsequent imaging show reversion of angiographic abnormality on day 4 (H) and new focal narrowing on day 28 (I)
