Primary hyperparathyroidism in a dog: biochemical, bone histomorphometric, and pathologic findings
Journal of the American Veterinary Medical Association
|December 1, 1986
Summary
Primary hyperparathyroidism in a dog was diagnosed through clinical signs, biochemical findings, and bone analysis. Surgical removal of a parathyroid adenoma was attempted, but the dog succumbed to renal failure.
Area of Science:
- Veterinary Medicine
- Canine Endocrinology
- Comparative Pathology
Background:
- Hypercalcemia presents with diverse clinical signs in dogs, including inappetence, polyuria, polydipsia, and vomiting.
- Primary hyperparathyroidism is a rare endocrine disorder characterized by excessive parathyroid hormone production.
- Accurate diagnosis is crucial for effective management and improved patient outcomes.
Observation:
- An adult Keeshond exhibited clinical signs consistent with hypercalcemia.
- Blood biochemical analysis and urinary clearance studies supported a diagnosis of primary hyperparathyroidism.
- Histomorphometric analysis of bone biopsy revealed increased bone remodeling activity.
Findings:
- Surgical exploration identified a parathyroid gland adenoma, which was surgically excised.
- Histological examination confirmed the diagnosis of parathyroid gland adenoma.
- The dog experienced postoperative renal failure and expired on the eighth day.
Implications:
- This case report highlights the diagnostic approach to primary hyperparathyroidism in dogs.
- Understanding the clinical presentation and diagnostic markers can aid veterinary clinicians in identifying this condition.
- The report contributes to the veterinary literature by defining primary hyperparathyroidism in canine patients.
