cerebellar veins cerebellar veins the cerebellar veins are veins which drain the cerebellum. they consist of the superior cerebellar veins and the inferior cerebellar veins (dorsal cerebellar veins). the superior cerebellar veins drain to the straight sinus and the internal cerebral veins. the inferior cerebellar veins drain to the transverse sinus, the superior petrosal sinus, and the occipital sinus. cerebellar veinscorresponding arterial circulation of the cerebellum (aica and pica).veins and plexa of the cerebellum seen.detailsdrains fromcerebellumdrains todural venous sinusesarteryanterior inferior cerebellar artery (aica), posterior inferior cerebellar artery (pica)identifierslatinvenae cerebellita98a12.3.06.056ta24935fma70879anatomical terminology structure the superior cerebellar veins pass partly forward and medialward, across the superior cerebellar vermis. they end in the straight sinus, 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. additional images diagram of the arterial circulation at the base of the brain. sagittal section of the cerebellum, near the junction of the vermis with the hemisphere.
