PURPOSE: This study reports the sonographic features of the pancreas in children who have dengue hemorrhagic fever (DHF) with epigastric pain, evaluates pancreatic abnormalities as the source of this pain, and relates sonographic findings, DHF status, and serum levels of amylase and lipase. METHODS: Over 3.5 years, real-time sonographic examination of the pancreas was prospectively performed in 148 children (age range, 5 months-14 years) who had DHF with epigastric pain. The DHF diagnosis was confirmed by serologic examination and viral isolation. RESULTS: Of the 142 children included in this study, 72 had mild DHF (grade I or II) and 70 had severe DHF (grade III or IV). An enlarged pancreas was found in 41 patients (29%), 10 (14%) of whom had mild DHF and 31 (44%) of whom had severe DHF. The pancreas was hyperechoic relative to the liver in 36 patients (25%), isoechoic in 98 (69%), and hypoechoic in 8 (6%). CONCLUSIONS: The majority of patients with DHF and epigastric pain do not have an enlarged pancreas, different echogenicity of the pancreas compared with the liver, or a dilated pancreatic duct. Thus, pathologic changes of the pancreas cannot be the only cause of epigastric pain in DHF patients. Increased serum levels of amylase and lipase are commonly seen in patients with severe DHF and an enlarged pancreas.
