Abstract

The present study aimed to investigate the use of ultrasound and differential diagnosis to diagnose a fetal abdominal cyst. A retrospective analysis of 41 cases of fetal abdominal cyst, which included ovarian cysts, choledochal cysts, intestinal duplication and mesenteric cysts, was performed. Imaging characteristics of various types of cysts were summarized, compared and discussed. Among 41 fetal abdominal cyst cases, there were 21 cases of ovarian cysts, 11 cases of bile duct cyst, six cases of intestinal duplication and three cases of mesenteric cyst. Each type of fetal cyst had its own distinctive characteristics on abdominal ultrasound examination. Ovarian cysts were located at one side of the bladder, round‑shaped and observed in female fetuses; choledochal cysts were located in the hilar, were oblong- or oval‑shaped and connected to the bile duct; intestinal duplication was located in the middle of abdomen, close to the intestine, and presented as an intestinal wall‑like structure; mesenteric cysts were round‑shaped with thin tensionless wall, presented with multiple chambers, and were easily deformable on compression. The findings of the present study demonstrated that a comprehensive analysis of the association between the cyst and its adjacent location, shape, wall thickness, motility and other aspects of dynamic changes via ultrasonography may provide a differential diagnosis of different types of fetal abdominal cysts.
