The "Wrinkle Sign" in Time-of-Flight Magnetic Resonance Venography is a Hallmark of Idiopathic Intracranial Hypertension
WORLD NEUROSURGERY(2024)
摘要
Idiopathic intracranial hypertension (IIH) is usually caused by sinus stenosis, which manifests in magnetic resonance venography (MRV) as occlusion or intraluminal webbing. We present the case of a 27-year-old patient with IIH, and time-of-flight (TOF) MRV only exhibited a rare "wrinkle sign," which was eventually proved to indicate sinus obstruction. The patient received venting and recovered. The TOF MRV provides a nonradioactive approach to identify IIH patients who potentially need intervention.
