Clinical and imaging features of brain herniation in dogs and cats

Brain herniation refers to shifting of brain structures relative to their normal position within the calvarium. There are five recognized types of brain herniation with caudal transtentorial herniation (CTH) and foramen magnum (FMH) herniation being most clinically relevant. Herniation occurs secondary to various intracranial lesions, and, historically, diagnosis relied on clinical signs and evidence of herniation on post-mortem examination. Relying on necropsy is problematic in that removal of the skull might disrupt the ability to discern herniation, and a poor prognosis is inevitable.
