Management challenges in a child with hyperinsulinemic hypoglycemia.

Area of Science:

• Pediatric Oncology
• Endocrinology
• Surgical Gastroenterology

Background:

• Malignant insulinoma is an exceptionally rare tumor in pediatric populations.
• Hyperinsulinemic hypoglycemia in infants can be caused by various conditions, including rare pancreatic tumors.

Purpose of the Study:

• To report the youngest known case of malignant insulinoma with metastatic disease in a child.
• To highlight the diagnostic and management challenges of pediatric malignant insulinoma.

Main Methods:

• Case presentation of an 18-month-old child with recurrent hyperinsulinemic hypoglycemia.
• Diagnostic imaging including Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) scan.
• Surgical management (enucleation and subtotal pancreatectomy) and histopathological confirmation with immunostaining.

Main Results:

• The patient presented with hyperinsulinemic hypoglycemia, initially treated with tumor enucleation and later subtotal pancreatectomy.
• Despite surgical interventions, metastatic insulinoma to the liver was confirmed.
• This case represents the youngest reported instance of metastatic malignant insulinoma in a child.

Conclusions:

• Malignant insulinoma, though rare, should be considered in pediatric cases of persistent hyperinsulinemic hypoglycemia.
• Early and accurate diagnosis, coupled with aggressive management, is crucial for pediatric patients with malignant insulinoma.
• Metastatic potential underscores the need for vigilant monitoring and advanced imaging in affected children.
