Zebra sign (cerebellum)

The zebra sign has been termed to describe the finding of layering of blood in amongst the folia of the cerebellum, particularly in the setting of supratentorial surgeries (temporal lobe resection), neuro-vascular neck surgeries, lumbar spinal surgeries possibly secondary to dural tear and interpreted as remote cerebellar hemorrhage 1-3.

This type of hemorrhage is characterized by a streaky pattern, like a zebra's stripes, due to blood spreading in the cerebellar sulci. 

The term zebra has also been used elsewhere in radiology, in the zebra stripe sign (bones).
