Crohn's disease patient with right lower quadrant abdominal pain for 20 years due to an appendiceal neuroma (Fibrous obliteration of the appendix).

摘要

Primary tumors of the appendix are uncommon and are usually not included in the differential diagnosis when a patient with inflammatory bowel disease (IBD) presents with either acute or chronic right lower quadrant abdominal pain.1'2 Appendiceal neuromas are proliferations of neural tissue and are categorized as one of the causes of fibrous obliteration of the appendix.3"7 We present a patient with left-sided colonic Crohn's disease (CD) who also had 20 years of intermittent severe right lower quadrant pain; the pain was thought to be due to CD involving the terminal ileum, but was due to an appendiceal neuroma (fibrous obliteration of the appendix).
