Diverse phenotypic manifestations of small intestinal mucosa in non-infectious common variable immunodeficiency bowel disease: A case report

Figure 3 Whole-small bowel double-balloon enteroscopy. A: Multiple segmental longitudinal mucosal lesions in the ileal segment; B-D: Mucosal lesions after indigo carmine staining at a distance and close up: Some of the villi on the surface were detached, there was no white moss or exudation at the base, and the mucosal swelling at the edge of the base was obvious as a nodule-like bulge, and the ileal villi around the lesion were flattened and atrophied.
