Insulinoma with six islet cell tumors associated with severe hypoglycemia.
A 43-year-old woman was admitted to hospital due to loss of consciousness. Her fasting plasma glucose and serum immunoreactive insulin levels were 14 mg/dL and 5 microU/mL, respectively. She needed continuous glucose infusion to avoid hypoglycemia. A dynamic abdominal CT scan revealed two hypervascular tumors in the pancreas. A pancreatectomy was performed and her blood glucose level was normalized. The pathological examination revealed six insulinomas but we could not find either parathyroid tumors or obvious pituitary tumor, which denied the possibility of multiple endocrine neoplasia type I. However, long-term follow-up will be necessary for monitoring the development of other tumors.
