He had anemia and jaundice in physical exam .His abdominal pain was after eating and we evaluated upper and lower parts of gastrointestinal and we didn't find any clue. All of the other imagings incuding,small bowel follow through,abdominal C.T. angiography and magnetic resonance enterography were normal. Finally,serum lead levels were measured and were 1961 mic/ dl [normal range of 10 mic/dl] elevated;Therefore established diagnosis was lead poisoning.
