A Wandering Abdominal Mass in a Neonate: An Enteric Duplication Cyst Mimicking an Ovarian Cyst

Abstract

Enteric duplication cysts are rare congenital anomalies that are prenatally diagnosed through antenatal ultrasonography (US). In female patients, however, attention must be paid since these formations might be confused with ovarian cysts. Herein, we present a case of a low birth weight female infant with an enteric duplication cyst. A cystic lesion was detected in the right abdomen of the fetus on antenatal US and magnetic resonance imaging (MRI). Serial US and MRI examinations performed after birth showed a single cyst that wandered from side to side in the abdomen; the initial diagnosis was thought to be an ovarian cyst. During laparotomy, however, it was found to be an enteric duplication cyst with volvulus. To our knowledge, there has been no report of an enteric duplication cyst presenting as a wandering abdominal mass. Our experience indicates that early intervention is necessary for patients who have a wandering abdominal mass to avoid complications and urgent surgery, whether it is an ovarian cyst or an enteric duplication cyst.

Rare Case of an Isolated Enteric Duplication Cyst in a Teenager

“…[6] MRI findings can support the sonographic findings, but may not give additional information on characterizing the cysts. [13] Histopathological examination confirms the clinical diagnosis of an enteric duplication cyst. The three essential histological microscopic features are: (1) a well-developed smooth muscle coat;…”

Prenatal imaging features and perinatal outcomes of foetal volvulus–A literature review

“…In 23 (26.1%) cases, 2,3,11,14,15,18,20,24,25,29–31,33–35,45,49–52 a variety of abnormal foetal heart rate patterns (reduced variability, lack of accelerations and decelerations) were present. Four infants 20,53–55 underwent antenatal MRI with findings of mesenteric mass, ovarian cyst, meconium cyst, and intraluminal intestinal haemorrhage.…”

“…Of the 66 cases 2,3,5–9,11–16,18–22,24–27,29–35,42,43,45–49,51–53,55,57–61,63–68 that reported the sex of the infant, 37 (56.1%) 2,6,8,9,12,13,19–22,25,26,29,31–35,42,47,51,52,58,60,63,66,67 were males. Seven (8.0%) infants 12,14,17,29,48,51,54 were part of a dichorionic diamniotic twin pregnancy whilst one (1.1%) infant 4 was from a monochorionic diamniotic pregnancy.…”

“…In all cases of multiple pregnancy only one twin was affected. Birth weight was reported for 61 infants 2,3,5–9,11,12,14,16,18–22,24–27,29–35,42,43,45–49,51–54,57–59,63–68 —the mean birthweight was 2400.2 g (SD 628.4). Of these, 11/61 (18.0%) 16,19,24,46–48,51,53,57 were classified as SGA.…”

“…Three (3.4%) foetuses 29,43,52 underwent prenatal paracentesis for foetal ascites, and 1 (1.1%) 27 underwent diagnostic cordocentesis. Following delivery, 71 (80.7%) cases 2–4,6–9,12–15,17–22,24–27,29–31,33–35,42–49,51–54,56–61,63–66 had recorded timeframes for treatment of volvulus. Fifty‐three (53/71, 74.6%) of these infants 2,4–8,14–17,19–21,24–26,30,31,33–35,42–47,49,51,52,54–59,63 were treated immediately after birth or within 24 h of age.…”
