Thus far, previous studies on the incidence of these anomalies and variants of venous PT have notable limitations; they used small sample sizes and did not include several recently described venous PT anomalies, such as a dehiscent sigmoid plate and petrosquamosal sinus.
5 mm; [sup][12] (7) petrosquamosal sinus, embryologic emissary vein running along the petrosquamosal Fissure; [sup][15] and (8) sinus thrombosis, signs of thrombosis were noted, including the empty ™-sign or an irregular filling defect.
sup][2],[27] The vascular anomalies and variants detected in this study are all factors potentially capable of changing normal perfusion (such as a dehiscent sigmoid plate, lateral sinus stenosis, sigmoid sinus diverticulum or jugular bulb diverticulum, large emissary vein, petrosquamosal sinus, and sinus thrombosis) or sound transmission (such as a dehiscent sigmoid plate and dehiscent jugular bulb).
