A young cat with insulinoma, a rare pancreatic tumor, experienced prolonged survival after surgical removal. This case highlights successful treatment for feline insulinoma, offering hope for similar conditions.

Area of Science:

  • Veterinary Medicine
  • Comparative Oncology
  • Endocrinology

Background:

  • Insulinoma, a rare pancreatic neuroendocrine tumor, can cause life-threatening hypoglycemia in cats.
  • Most reported feline insulinomas are malignant and occur in older cats.
  • This case presents a unique instance of insulinoma in a younger cat.

Observation:

  • A 14-year-old domestic shorthair cat presented with severe hypoglycemia and seizures.
  • Diagnostic workup revealed hypoglycemia with normal insulin levels, suggesting insulin resistance or an insulin-secreting tumor.
  • Surgical exploration identified a solitary pancreatic mass consistent with insulinoma.

Findings:

  • Histopathological analysis confirmed the pancreatic mass as an islet cell carcinoma (insulinoma).

  • The cat underwent surgical resection of the insulinoma.
  • Postoperative recovery included management of pancreatitis, with no signs of recurrence observed for over 32 months.
  • Implications:

    • This case demonstrates the potential for successful surgical management and prolonged survival in feline insulinoma, even in younger animals.
    • The apparent lack of recurrence and metastasis in this case contrasts with previous reports of malignant feline insulinomas.
    • Further research into feline insulinoma is warranted, particularly regarding prognostic factors and long-term outcomes.
