Case ReportsSegmental dilatation of the jejunum resembling prenatal volvulus☆

Case report
Routine ultrasound scan in a 24-year-old woman (gravida 1) at 30 weeks' gestation showed mild polyhydramnios, a dilated small bowel loop, and scoliosis. Amniocentesis showed a normal karyotype.
Repeat ultrasonography at 37 and 38 weeks' gestation showed increasing polyhydramnios as well as a marked increase in diameter of the dilated bowel loop (Figs 1 and 2).
Discussion
Since the first description of segmental diltation of the colon by Swenson and Rathauser in 19593 several reports affecting the small and large bowel have been published. Common features include a single, dilated bowel segment without evidence of intrinsic or extrinsic obstruction or abnormal innervation. Gross appearance frequently includes enlarged and tortuous vessels, thick bowel wall, or, sometimes, a paper-thin walled intestinal segment.4, 5

Segmental dilatation of colon detected on prenatal ultrasound
2019, Journal of Pediatric Surgery Case ReportsCitation Excerpt :Other clinical presentations, including abdominal pain, gastrointestinal bleeding, and anemia, are nonspecific. Associated anomalies are found in more than 50% of patients with SDI, and include anorectal anomaly, malrotation, and omphalomesenteric duct [6,7,8,9]. SDI is difficult to diagnose not only prenatally but also antenatally, especially preoperatively.
Antenatal ultrasonographic features associated with segmental small bowel dilatation: An unusual neonatal condition mimicking congenital small bowel obstruction
2013, Pediatrics and NeonatologyCitation Excerpt :In some cases, association of Meckel diverticulum with SDI has been reported.2 SDI associated with prenatal ultrasonographic (US) findings, mimicking prenatal volvulus, cystic mass or bowel stenosis, has rarely been described.3–8 However, the diagnosis of SDI was confirmed at surgery in all cases.
