RESUMO
¹⁸F-DOPA PET/CT is commonly done in patients with persistent hyperinsulinemic hypoglycemia of infancy (PHHI) to look for any focal lesion in the pancreas.We present the findings in a 20-day-old neonate with PHHI who underwent ¹⁸F-DOPA PET/CT. The scan showed diffuse uptake in the pancreas with no focal lesion, physiologic excretion into the genito-urinary system, and interestingly tracer accumulation was seen in the inferior vena cava and ilio-femoral veins which is a non-physiological site for tracer accumulation. The uptake corresponded to a large venous thrombus which was confirmed by a venous Doppler.

PURPOSE: Persistent hyperinsulinemic hypoglycemia of infancy(PHHI), which is characterised by inappropriate insulin secretion in spite of hypoglycemia, needs urgent treatment to prevent cerebral hypoglycemic damage. Although pancreatectomy is the treatment of choice for PHHI, there are several complications which follow treatment. We suggest that aggressive medical therapy, when effective, is preferable to partial pancreatectomy. METHODS: We evaluated 8 patients with PHHI admitted to the Department of Pediatrics, Samsung Medical Center from November 1996 to January 1999. Children with hypoglycemia in the range of 3-50mg/dl were included. Octreotide was administered at dosage of 100-150 microgram/day. When the patients did not respond to octreotide, diazoxide and nifedipine were given in addition. RESULTS: In four of eight patients, octreotide was discontinued after 15 to 165 days. One patient was given diazoxide instead. The remaining 3 patients are still being treated with octreotide. CONCLUSION: We believe that maximum effort should be made to attain euglycemia with medication, and pancreatectomy should be reserved for patients in whom these measures fail to restore normoglycemia.
