A Doberman Pinscher experienced dysequilibrium due to a cerebellomedullary pontine angle lesion. Histopathology revealed this mass was a choroid plexus cyst, offering insights into canine neurological conditions.

Area of Science:

  • Veterinary Neurology
  • Comparative Pathology
  • Neuroimaging

Background:

  • Dysequilibrium in canine patients can indicate central nervous system abnormalities.
  • Accurate lesion localization is crucial for diagnosing neurological disorders in dogs.
  • Cerebellomedullary pontine angle lesions require detailed investigation due to proximity to vital structures.

Observation:

  • A 6-year-old Doberman Pinscher presented with a 2-month history of dysequilibrium.
  • Computed tomography revealed a well-defined, circular, hypoattenuating mass (4 x 8 mm) at the cerebellomedullary pontine angle.
  • The lesion exhibited peripheral ring enhancement post-contrast administration and was isoattenuating to cerebrospinal fluid.

Findings:

  • Histopathological examination confirmed the mass as a choroid plexus cyst.

  • The imaging characteristics were consistent with a cystic lesion in the cerebellomedullary pontine angle.
  • The cyst's location correlated with the observed clinical signs of dysequilibrium.

    • Implications:

    • This case highlights choroid plexus cysts as a potential cause of neurological deficits in dogs.
    • Neuroimaging findings, particularly contrast enhancement patterns, aid in differentiating cystic lesions.
    • Understanding such pathologies contributes to the diagnostic and therapeutic strategies for canine neurological diseases.
