It may be genetic or occur sporadically.Cerebral vasospasm: Cerebral vasospasm is the prolonged, intense vasoconstriction of the larger conducting arteries in the subarachnoid space which is initially surrounded by a clot.Subarachnoid hemorrhagePlatybasiaArnold–Chiari malformationEchoencephalographyIntracranial pressure monitoringSyringomyeliaClivus (anatomy): The clivus (Latin for "slope") is a part of the cranium at the skull base, a shallow depression behind the dorsum sellæ that slopes obliquely backward. It forms a gradual sloping process at the anterior most portion of the basilar occipital bone at its junction with the sphenoid bone.CisternaHydrocephalusFascioloides magna: Fascioloides magna, also known as giant liver fluke, large American liver fluke or deer fluke, is an important parasite of a variety of wild and domestic ruminants in North America and Europe.

These include domestic cat (both house cats and feral), of the species Felis catus; medium-sized wild cats from the genus Lynx; and big cats from the genera Puma and Panthera.Cerebral softeningNew Zealand rabbitLow-voltage electron microscope: Low-voltage electron microscope (LVEM) is an electron microscope which operates at accelerating voltages of a few kiloelectronvolts or less. While the low voltage electron microscopy technique will never replace conventional high voltage electron microscopes, it is quickly becoming appreciated for many different disciplines.
