The cerebellar veins are veins which drain the

cerebellum The cerebellum (Latin for "little brain") is a major feature of the hindbrain of all vertebrates. Although usually smaller than the cerebrum, in some animals such as the mormyrid fishes it may be as large as or even larger. In humans, the cere ...

. They consist of the superior cerebellar veins and the inferior cerebellar veins (dorsal cerebellar veins). The superior cerebellar veins drain to the

straight sinus The straight sinus, also known as tentorial sinus or the , is an area within the skull beneath the brain. It receives blood from the inferior sagittal sinus and the great cerebral vein, and drains into the confluence of sinuses. Structure The s ...

and the internal cerebral veins. The inferior cerebellar veins drain to the transverse sinus, the superior petrosal sinus, and the occipital sinus.

Structure

The superior cerebellar veins pass partly forward and medialward, across the superior cerebellar vermis. They end in the

, and the internal cerebral veins, partly lateralward to the transverse and superior petrosal sinuses. The inferior cerebellar veins are larger. They end in the transverse sinus, the superior petrosal sinus, and the occipital sinus.

Clinical significance

The cerebellar veins may be affected by infarction or thrombosis. They may be the draining site of abnormal fistulas.
