Primary intestinal lymphangiectasia diagnosed by capsule endoscopy and double balloon enteroscopy

Figure 1 Capsule endoscopy shows diffuse edematous mucosae covered with enlarged and swollen villi in the jejunum (A), and diffuse finger-like elongated mucosa covered with enlarged whitish villi in the ileum (B).

Figure 2 Capsule endoscopic findings in the duodenum (A), jejunum (B) and ileum (C).

Figure 3 Double balloon enteroscopy was performed with biopsy forceps to obtain a small bowel specimen of polypoid mucosa covered with enlarged whitish villi (A); and additional double balloon enteroscopic findings (B, C).

Figure 4 Histology of mucosal tissue in the jejunum shows multiple dilated lymphatics. A: HE, × 40; B: HE, × 100.
