Intermittent melena and refractory anemia due to jejunal cavernous lymphangioma: A case report

Figure 1 Different sections of abdominal contrast-enhanced computed tomography image showing nonenhancing masses on diseased jejunal mesentery (orange arrow). A: Sagittal plane image; B: Coronal plane image; C: Transverse plane image.

Figure 2 Representative images of single-balloon enteroscopy. A: Characteristic endoscopic manifestations of edematous white-yellow mucosa accompanied by hemorrhagic red spots (white arrow); B and C: Images demonstrate multiple active bleeding lesions (white arrow).

Figure 3 Microscopic features of the biopsy specimens. A: The mucosal lamina propria and submucosa exhibited variably sized cysts, which were filled with lymphatic fluid and contained red blood cells and lymphocytes within the lumen (hematoxylin–eosin staining); B: Positive immunohistochemical staining for D2-40 was observed.

Figure 4 Intraoperative findings and resection specimen. A: Numerous cystic and hemorrhagic masses of varying sizes were observed on the mesentery; B: The length of the diseased jejunum exceeded 10 cm. Longitudinal gross dissected specimens revealed that various sizes of nodular eminence were distributed on the lumen surface.
