Article Abstract
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.

View Article and Find Full Text PDFWe describe here a skin configuration present during tear duct probing in cases of canalicular and common internal punctal obstruction which we term the "wrinkle sign." The technique for eliciting the sign and the significance of its presence is described. Observation of the "wrinkle sign" is a useful adjunct to the standard technique of tear duct probing.
