ABSTRACT
The metastatic calcification is defined as the deposition of calcium salt in normal tissue with an abnormal serum biochemical environment, such as chronic kidney disease, hyperparathyroidism, and hypercalcemia related with malignancy. Although the metastatic calcification can develop in any organs and tissues, presenting its symptoms and complications are rare. Thus a few cases have been reported. This case shows the metastatic calcification of the small intestine without any peritoneal and mesenteric vascular calcification which was early diagnosed by computed tomography and mesenteric angiography in a patient with abdominal pain, receiving continuous ambulatory peritoneal dialysis due to end stage renal disease. The clinician should early consider the metastatic calcification as differential diagnosis when unidentified calcifications are noted in simple abdominal X-ray such as in the present case, and promptly confirm it by using appropriate diagnostic tests in order to prevent its complications and progression.
