Small intestinal vascular malformation bleeding: A case report with imaging findings

Figure 1 Skin, enteroscopy, abdominal vascular enhanced computed tomography, laparoscopy and pathological findings of the patient. A: Pathological analysis showed cavernous angioma on the right knee (× 400); B: Angioma was indicated by oral approach enteroscopy; C: Arterior-venous malformation at the branch of the superior mesenteric artery was shown by abdominal vascular enhanced computed tomography (CT); D: Contrast media remained in the arterior-venous malformation, as shown by abdominal vascular enhanced CT at the cross section; E: Contrast media remained in the arterior-venous malformation, as shown by abdominal vascular enhanced CT in a reconstruction of a coronal view; F: A small intestinal angioma was detected by a laparoscopic approach; the tissue in this image corresponds to B; G: Arterior-venous malformation was found by a laparoscopic approach; the tissue in this image corresponds to C-E; H: By pathological examination, the resected small intestinal arterior-venous malformation was shown to have a vessel wall that was irregular, distorted and dilated (× 400).
