Chronic pancreatitis is described in a 10-year-old boy with mitochondrial myopathy due to cytochrome c oxidase (complex IV) deficiency. There have been few reports of chronic pancreatitis associated with congenital metabolic diseases. Marked pancreatic calcifications and pseudocysts of the pancreatic head and tail were demonstrated by computed tomography of the abdomen and by endoscopic retrograde pancreatography, which were thought to be useful methods for morphological examination of the pancreas. In the patient, no possible etiological factors were identified, including anomalous pancreatobiliary ductal junction or biochemical abnormalities. The association between cytochrome c oxidase deficiency and chronic pancreatitis remains to be established.

In a case with chronic pancreatitis and pseudocysts related to muscular cytochrome-c oxidase deficiency, endoscopic ultrasonography (EUS) was performed to morphologically examine the pancreas for features that may have been missed by abdominal computed tomography and pancreatography. Conventional abdominal sonography had failed to show valuable diagnostic information of chronic pancreatitis in this case. EUS demonstrated several new findings. Parenchymal atrophy was remarkable, especially in the pancreatic tail, and a dilated pancreatic main or branch duct was clearly found in the region. Moreover, pancreatic stones in the main duct were also distinctly proved. EUS may become a useful new diagnostic method in pediatric gastroenterology, especially when sufficient findings are not obtained by conventional imaging techniques. However, an ultrasonographic endoscope with a shorter rigid portion and smaller caliber should be developed for pediatric patients.
