Plain-English summary
An 8-year-old Yorkshire terrier suddenly fell into a coma and had seizures after hitting its head. The vet suspected bleeding in the brain and used magnetic resonance imaging (MRI) to find a round mass in the dog's brain, indicating an acute hemorrhage. Over the next several days, the vet monitored the mass with daily MRIs, noting changes in its appearance as the bleeding evolved. While the dog faced serious challenges, the imaging helped the vet understand the situation better.

Abstract
An 8-year-old Yorkshire terrier developed acute onset coma and seizure after cranial trauma. Intracranial hemorrhage was suspected from the clinical signs and history. Low-field magnetic resonance (MR) imaging revealed a round mass within the right cerebral hemisphere, compressing the right lateral ventricle and displacing the longitudinal fissure to the left. The lesion was hypointense on T1-weighted images and hyperintense on T2-weighted images, consistent with an acute hemorrhage. MR imaging was performed every 24 h for 6 days from 1 h after the injury, and then on day 14 of hospitalization. With time, the signal intensity changed to hyperintense on Ti-weighted images. On T2-weighted images the center of the mass changed to hypointense, and then to hyperintense with a hypointense rim. These changes of signal intensity were related to hemoglobin oxidation.
