CT – normal brain and ventricular system in a 7 year old FS Shih Tzu dog with seizures

 This 7 year old FS ShihTzu dog presented to RDVM a couple of weeks ago for apparent severe neck pain.  This morning started having seizure-like activity, circling, horizontal nystagmus,  progressing to alligator rolling with rapid horiz. nystagmus. She does not lose consciousness during these episodes, but they do appear to be focal seizures. Happening approximately every 15-20 minutes.

Physical Exam: horizontal nystagmus, alligator rolling.

Image Interpretation

CT of the skull, plain and post contrast- There is no evidence of mass pathology within the brain or surrounding structures.
The cerebral hemispheres exhibit symmetric vasculature and ventricles. No evidence
of abnormal parenchymal contrast enhancement is identified at any level within the
cerebral cortical anatomy. The brainstem and cerebellum are normal. No abnormalities
are identified in the limited included portions of the cranial cervical spine. The
tympanic bullae are normal. There is mild enlargement of the left medial
retropharyngeal lymph node. The mandibular lymph nodes are mildly thickened. No
abnormalities are identified in the nasal passages. The orbits are normal. There are
resorptive horizontal and vertical bone ch

DX

1. Normal brain parenchyma and ventricular system. 2. Periodontal disease. 3. Mild lymphadenopathy, most likely reactive/inflammatory, mandibular and medial retropharyngeal regions. These likely result of periodontal infectious disease.

Outcome

There is no evidence of structural brain disease. Seizure activity is not explained.
Careful oral cavity evaluation for additional assessment of the observed dental lesions
is suggested, including intraoral high-resolution radiographic assessment of dental
arcade anatomy.
