This case emphasizes the importance of not confusing extrinsic compression of a dural venous sinus by extradural hemorrhage with actual thrombus within the sinus. It is important to remember that skull fractures can be complicated by dural venous sinus thrombosis but one must be careful to distinguish thrombus within the vessel lumen itself from extrinsic compression.  Overcalling thrombosis in the setting of trauma may lead to unnecessary anticoagulation and risk of hemorrhage from other sites of trauma.
