Cerebral venous sinus thrombosis (CVST) related to intracranial tumors has most commonly been recognized as an operative complication related to local operative factors such as retraction or direct venous injury. CVST may also be caused by tumor-related factors such as local mass effect but rarely occurs geographically remote from the site of the tumor. We report 6 cases treated at our institution of intracranial supratentorial tumors associated with CVST. In each case, the CVST was remote from the surgical site. In 3 cases CVST was noted at the time of resection, and 3 cases occurred in a delayed fashion. Each case is discussed in detail, and the utility of intraoperative magnetic resonance imaging in the early diagnosis of this complication is highlighted.
