Volvulus secondary to cystic ileal duplication: Importance of prenatal imaging and prompt post-natal intervention

Duplications of the alimentary tract are rare malformations, and ileum is the most involved intestinal tract. During fetal life, they are usually occasional findings and may be asymptomatic until adulthood. We present the clinical case of volvulus on ileal cystic duplication diagnosed by ultrasound during prenatal follow-up.Case report: Diagnosis of cystic ileal duplication was made by ultrasound at our center at 23 weeks of gestational age, which was confirmed with fetal MRI. During follow-up, at 36 + 4 weeks, the presence of dilated loops with reduction of peristalsis was shown by ultrasound, so that, despite stable fetal parameters, an emergency caesarean delivery was programmed for suspected volvulus. After being stabilized, the patient underwent to laparotomy that revealed ileal volvulus at 2 cm from the ileo-cecal valve on a cystic duplication. Cyst and necrotic loop (10 cm) was resected and was performed an anastomosis. Patient started feeding on VII post-operative day, and was discharged on the X day. Patient is on follow up and present good conditions.Discussion: Diagnosis of intestinal cystic mass in prenatal period requires a close follow-up because the risk of a volvulus. According to the literature, even in the presence of stable fetal parameters, the presence of dilated loops and the absence of peristalsis are signs that must suspect the presence of a mechanical occlusion for which timely treatment is necessary to reduce mortality and morbidity.
