Core Tip
Core Tip: We report a case of non-infectious common variable immunodeficiency (CVID) patient associated bowel disease with non-specific clinical manifestations, which is characterized by B-cell dysfunction and reduced levels of serum IgG. The disease is rare and the etiology and pathogenesis remain unknown, making it difficult to diagnose, thus resulting in high mortality. Whole small intestinal double balloon enteroscopy is helpful for early diagnosis and reveals the involvement of the whole small intestinal mucosa. This case emphasizes that timely diagnosis, effective intervention and follow-up management are essential to improve the outcome of CVID patients.
