Peutz-Jeghers syndrome: CT and US demonstration of small bowel polyps

A family affected with Peutz-Jeghers syndrome is reported with an emphasis on radiological findings. A patient showed extensive pigmentation around the lips, buccal mucosa, and nose. Another showed prolonged transient intussusception of a jejunal loop on barium meal examination, and massive rectal bleeding. In this patient, small bowel polyps could also be seen on ultrasonography (US) and computed tomography (CT). On CT several polyps, up to 3 cm in size, were detected along with a carpeting pattern of several loops presumably caused by multiple small polyps.
