Area of Science:

  • Endocrinology
  • Oncology
  • Gastroenterology

Background:

  • Insulinomas are rare neuroendocrine tumors of the pancreas that secrete excess insulin.
  • These tumors can lead to hypoglycemia, causing symptoms like fainting and weight gain.

Observation:

  • A 40-year-old male presented with recurrent fainting spells and a 2-year history of weight gain.
  • His lab results showed fasting hypoglycemia (50 mg/dl) and an insulin-to-glucose ratio of 0.6.
  • Abdominal CT revealed a solitary pancreatic body tumor.

Findings:

  • Surgical exploration confirmed a solitary tumor in the pancreatic body.
  • Microscopic examination identified the tumor as a benign insulinoma.
  • The postoperative recovery was uneventful.

Implications:

  • Benign insulinomas require prompt diagnosis and surgical management to prevent hypoglycemic episodes.
  • While surgical outcomes are generally favorable, potential complications like pulmonary embolism must be considered.
  • This case highlights the importance of investigating unexplained hypoglycemia with imaging and biochemical tests.
