Abstract
A dog with acute neurological signs consistent with head ptosis, stooped posture, neck pain and tonic seizure showed increased white blood cells and C-reactive protein in a blood cell count and serum bio-chemistry. An MRI revealed intracranial and extracranial lesions with the contrast-enhancing ring-shaped effect characteristically seen in abscesses, connected to each other, which extended to the dorsal of the hard palate. A large number of neutrophils on smear preparation and γ-Streptococcus with bacteria culture were detected in the extracranial lesions. Based on these findings, the dog was diagnosed with an intracranial abscess, probably derived from periodontitis. We successfully treated the intracranial abscess using antibiotics, without surgical treatment. In an MRI on the 50th day, the ring-shaped lesions had completely disappeared.
