Prenatal Diagnosis of Omphalocele on Antenatal Sonography: A Case Report

A wide spectrum of anterior abdominal wall defects exist having varying outcomes, the most common being omphalocele and gastroschisis followed by bladder, cloacal exstrophy, Pentalogy of Cantrell and body stalk deformity. The final outcome of these defects is significantly affected by the presence of additional structural and / or chromosomal abnormalities, Hence, it is very important to accurately diagnose and classify these defects as they have different prognosis and management. The key features to differentiate these lesions are based on the-1) site of abdominal defect-midline, para midline, infraumblical, 2) umbilical cord insertion-normal, abnormal 3) size of the defect and organs eviscerated, 4) presence or absence of covering membrane and 5) any associated congenital/ chromosomal anomaly. Here we are reporting a case of omphalocele, which was diagnosed on routine antenatal ultrasonography and will be discussing the diagnostic algorithm to differentiate other entities of anterior wall defects
