case_images: Physical examination (Figure 1) showed clubbed nails on all four limbs, pectus carinatum with lordosis, right lower abdominal tenderness, and no rebound pain.
case_images: Endoscopy showed (a and b) telangiectasias in the duodenum and stomach and (c

case_images: fig2-17562848221142913
case_images: Gastroscopy showed telangiectasia of the duodenum and fundus of the stomach [Figure 2(a) and (b)], and multiple colon polyps with a long, stalk-like and lobulated appearance [Figure 2(c) and (d)].
case_images: CTA of both lungs showed (a and b) obvious thickening, an arteriovenous
  anastomosis, forming a malformed vascular mass shadow, and "I-shaped"
  embolism nail. Abdominal enhanced CT showed (c and d) intussusception with
  significant thickening and enhancement of the local intestinal wall,
  suggesting multiple polyps.

case_images: Pulmonary artery computed tomography angiography (CTA) showed multiple pulmonary AVMs in both lungs (Figure 3(a) and (b)). Low-tension CT of the small intestine (Figure 3(c) and (d)) showed multiple polyps and right abdominal intussusception, and a right portal vein right hepatic vein fistula was considered.
