Importance of the Ultrasonography in Diagnosis of Ileal Duplication Cyst

Abstract

Gastrointestinal duplication cysts are rare congenital anomalies that can be seen in anywhere of the gastrointestinal system from the mouth to the anus. These are prenatally diagnosed through antenatal ultrasonography. However, attention must be paid since these formations might be confused with ovarian or mesenteric cysts. Our patient, who had been diagnosed with ovarian cyst on the ultrasonography performed in another center and with mesenteric cyst based on the abdominal MRI carried out at fifth month of life, presented to our clinic with the only complaint of constipation at 9th month of life. The diagnosis was set through double wall appearance of duplication cyst on the abdominal ultrasonography. The patient's cyst was resected.

Enteric duplication in children: A case series

“…They mostly present in paediatric age group. [4] The first case of duplication cyst was reported by Calder in 1733. [5] Previously, EDs had been called as giant diverticula, enterogenous cysts, giant thoracis cysts, duplication and unusual Meckle's diverticula.…”

Abdominal ultrasonography of the pediatric gastrointestinal tract

“…Gastrointestinal duplication cyst is an additional segment of fetal gut that can occur from the esophagus to the rectum, most commonly at the terminal ileum [14][15][16][17] . Gastrointestinal duplication cysts demonstrate a connection with the gastrointestinal (GI) tract by a common wall of serous and muscle membrane, usually without luminal communication, and may contain ectopic pancreatic tissue [15][16][17] .…”

“…Gastrointestinal duplication cysts demonstrate a connection with the gastrointestinal (GI) tract by a common wall of serous and muscle membrane, usually without luminal communication, and may contain ectopic pancreatic tissue [15][16][17] . Complications include ulceration, hemorrhage, perforation, and inflammation [15] .…”

“…On ultrasound, gastrointestinal duplication cysts are fluid-filled structures, typically with a central anechoic component [15] . The mucosal and submuscosal layers are echogenic, and the shared muscularis layer is hypoechoic [15,17] ( Figure 2C). Rarely, other abdominal cysts may have a "pseudo gut signature", including mesenteric cysts and teratomas; high-resolution transducers should delineate multiple bowel wall layers in true duplication cysts [18,19] .…”

Unusual Case of Jejunal Duplication in A64-Year-Old Female

“…There are several theories explaining the duplication process, and these including the aberrant luminal recanalization theory, the diverticular theory, and the notochordal split theory which consists on neurenteric duplications associated with vertebral anomalies [11]. Duplications may be cystic, tubular, or mixed and can occur in any part of the gastrointestinal tract, but the terminal ileum is more commonly affected.…”
