Small Bowel Intussusception Secondary to Peutz-Jeghers Polyp

Clinics in diagnostic imaging (159)

“…Spontaneous mutations give rise to some cases. (1)(2)(3)(4) Lip and buccal mucosae are common locations for mucocutaneous pigmentations. The eyelid, dorsal aspect of the fingers and sole of the foot are less common locations.…”

“…Other rare sites that develop polyps include the kidneys, ureter, nasal passages and bronchial tree. (4,6,7) Imaging usually shows multiple polyps and it is unusual to see only a solitary polyp. Large polyps have a lobulated appearance.…”

“…coiled-spring sign) due to barium outlining the oedematous mucosal folds of the returning limb of the intussusceptum. (4,11) US typically reveals a 'pseudokidney' or 'doughnut' appearance, which consists of inner hyperechoic mesenteric fat that is dragged inside, between the entering and returning limbs of the intussusceptum and the outer hypoechoic rim, due to the oedematous wall of the intussuscipiens. (4,12) CT shows a 'bowelwithin-bowel' appearance of the intussusceptions, seen as a sausage-shaped mass along the longitudinal axis of the bowel and a target-shaped mass perpendicular to the long axis of the bowel (Fig.…”

“…3b). (4,13) Patients with Peutz-Jegher syndrome have an increased risk of GIT malignancies, with an estimated risk of 2%-20%. The stomach, duodenum and colon are the most common locations.…”

Adult Intussusception in Patients with Peutz-Jeghers Syndrome: Case Series and Review of Literature

“…Pelvic, testicular, and pancreatic US screening should also be considered. Gastrointestinal tract screening can be performed with upper and lower endoscopy in combination with small bowel capsule endoscopy [16]. We designed this study to analyze the clinical characteristics, preoperative diagnosis, and surgical management of PJS associated-intussusception in adults.…”
