We report a case of atypical cerebral venous drainage in a 38-year-old woman with symptoms of benign paroxysmal positional vertigo. Thrombosis of the left internal jugular vein and sigmoid sinus was suspected on the basis of spin-echo and time-of-flight MR findings, but multisection CT angiograms showed a patent sigmoid sinus and predominant drainage via the emissary veins toward the vertebral plexus, with only a minor contribution of the jugular veins. This case illustrates the variability of the venous anatomy in the craniocervical region.
我们报告一例38岁患有良性阵发性位置性眩晕症状的女性非典型脑静脉引流病例。根据自旋回波和时间飞跃磁共振成像结果怀疑左侧颈内静脉和乙状窦血栓形成，但多层面CT血管造影显示乙状窦通畅，主要通过导静脉引流至椎静脉丛，颈静脉的引流作用较小。该病例说明了颅颈区域静脉解剖结构的变异性。
