Abstract / Description of output

A ten-month-old male Yorkshire terrier dog was evaluated on CT four months after traumatic brain injury. Cranial CT scans showed dilated ventricles associated with a peripheral crescent-shaped collection of blood near the right parietal bone with a mineralized area. The visceral layer of the hematoma was hyperattenuating before contrast and underwent contrast enhancement after administration of intravenous iodinated contrast. No fractures were identified in the calvarium. These findings were compatible with acute-on-chronic calcified subdural hematoma, which have been described with more detail in humans. This is the first report to include the description of the imaging findings related to this condition using computed tomography in dogs.
