Neurology, Head and neck
Seizures and walking in circles. CT found a lesion in the brain
- Patient
- dog, Staffordshire Bull Terrier, male, 11 years
- Examination
- CT of the head, pre- and post-contrast
- Date
- August 2026
For the past month, an eleven-year-old dog had been having epilepsy-like seizures and turning in circles to the right. The vet recommended a CT scan of the head to look for the cause in the brain and skull.
In the right hemisphere of the brain, the CT found a lesion about two centimetres in size that was pressing on its surroundings: the falx, the natural dividing wall between the hemispheres, was pushed slightly to the left. On the right, the thin bone that separates the brain from the nasal cavity was damaged, but the change had not grown into the nose. The CT also picked up breakdown of the necks of two teeth in the right upper jaw, with bone loss around one of them.
