During regular dissection classes, we came across tripled falx cerebelli in a male cadaver. The main (middle) falx cerebelli was large and was attached to the internal occipital crest. It contained the occipital sinus. There were two smaller folds (right and left), one on either side of the falx cerebelli. There were two aberrant venous sinuses; each one connecting the ipsilateral sigmoid and transverse sinuses with each other. The complex dural-venous variation reported here is seldom reported in the literature. Knowledge of such variation is important for neurosurgeons and neuroradiologists as these aberrant folds could cause haemorrhage during suboccipital approaches or may lead to erroneous interpretation during imaging of the posterior cranial fossa.
在常规解剖课上，我们在一具男性尸体中发现了小脑镰三联征。主要（中间）小脑镰较大，附着于枕内嵴，内含枕窦。在小脑镰两侧各有一个较小的皱襞（右侧和左侧）。存在两条异常静脉窦，每条都将同侧乙状窦和横窦相互连接。本文报道的这种复杂硬脑膜 - 静脉变异在文献中很少见。了解这种变异对于神经外科医生和神经放射科医生很重要，因为这些异常皱襞可能在枕下手术入路时导致出血，或者在颅后窝成像时导致错误解读。
