A Case of Terminal Ileitis Caused by Ascaris lumbricoides / 대한소화기내시경학회지

The major causes of terminal ileitis are inflammatory bowel disease and NSAIDs but parasites such as Anisakis rarely induce ileitis. Ascaris lumbricoides, the most common intestinal helminth in Korea, may enter the pancreaticobiliary ducts and cause pancreatitis or cholangitis. However, no case of A. lumbricoides-associated terminal ileitis has been previously reported in Korea. We report a case of a 58-year-old woman who presented with epigastric discomfort and bloating, and was diagnosed with terminal ileitis due to A. lumbricoides detected during colonoscopy.
