Abstract

Fetal abdominal cysts are rare. The significance of antenatally discovered abdominal cysts can range from an innocuous finding to serious conditions needing surgery. It is often difficult to arrive at a correct diagnosis based on ultrasonography, as different types of cysts can have similar appearances. A more specific diagnosis is possible if fetal sex, age at appearance, location of the cyst, shape and appearance of the walls, and contents are considered. This review presents an extensive spectrum of fetal abdominal cysts. The common as well as the very rare causes that have only a few reports are discussed. Ultrasound images of confirmed cases are also presented. An algorithmic approach that enables a more specific diagnosis in many cases has been developed.
