Prenatal Diagnosis of Circumvallate Placenta and Pregnancy Outcomes

INTRODUCTION: The objective of this study was to determine pregnancy-related outcomes associated with circumvallate placenta identified on ultrasonography among women referred to a large tertiary fetal diagnostic center. METHODS: A nested case–control analysis was conducted among referrals to the University of California–San Diego Fetal Care and Genetics Center between January 2003 and July 2012. Cases of circumvallate placenta were diagnosed in the first or second trimester and matched one-to-two with consecutively selected women in a control group based on maternal age, parity, and gestational age at diagnosis. RESULTS: Between January 2003 and July 2013, 81 singleton cases of circumvallate placenta were identified. Of these cases, 19 (23%) were diagnosed in the first trimester. Outcome data were available for 65 patients. No significant difference between low birth weight, preterm delivery, or 5-minute Apgar score was seen between groups. CONCLUSION: The clinical significance of circumvallate placenta remains unclear. Larger cases series are needed to determine its effect on obstetric outcomes.

Sonographic detection of an infected maternal urachal cyst during pregnancy

Infection of a maternal urachal cyst during pregnancy is rare; Sonography is an important diagnostic tool that can help minimize maternal and fetal complications. We describe the case of a 35‐year‐old multiparous woman presenting in the third trimester with 2 weeks of fever, abdominal pain, and urinary symptoms. Imaging showed a 5‐cm complex anterior midline mass, found intraoperatively to be eroding into the uterus. Sonographic imaging aided in the diagnosis and management of the urachal cyst, and antepartum sonographic measurements of the lower uterine segment helped to counsel regarding a trial of labor. Following treatment, the patient stabilized and had an uncomplicated vaginal delivery.
