Plain-English summary
A group of dogs with brain tumors were studied to see how these tumors affected their neurological health. Out of 153 dogs, 54 showed signs of brain herniation, which can happen when a mass pushes brain tissue out of its normal position. Interestingly, many dogs had significant brain shifts without obvious symptoms like eye movement problems. This means that even if a dog seems fine, there could still be serious issues going on in the brain. Treatment options would depend on the specific case, and early detection is crucial for better outcomes.

Abstract
Retrospective analysis of magnetic resonance imaging and clinical findings in a referral population of dogs was used to determine the relationship between rostrotentorial space-occupying lesions and the development of secondary neurological signs. Brain herniation was detected in 54/153 cases of uni-focal rostrotentorial space-occupying lesions; of these 30 had caudal transtentorial herniation (CTH) and 24 had both transtentorial and foramen magnum herniation (CTH/FMH). Masses associated with herniation were larger and situated more dorsally and caudally within the cranial vault. Clinical signs classically associated with CTH, e.g., oculomotor nerve palsy, were seen in only one case of isolated CTH and seven (14%) of all herniation cases. Deficits in caudal cranial nerve function were detectable in 39% of cases with FMH. We conclude that severe shifts in brain parenchyma can exist in the absence of detectable localising signs.
