Association of sex of the fetus in isolated fetal choroid plexus cysts

We sought to determine if an association exists between sex of the fetus an d the finding of isolated fetal choroid plexus cysts. Of 131 fetuses, 62 we re male (47.3%) and 69 were female (52.7%). No statistically significant di fferences were found in the maternal demographic parameters studied (age, r ace, gravidity, parity, sonogram timing) or descriptive cyst information ob tained (location, number, dimensions, resolution), although bilaterality wa s more common in male fetuses. The determination that isolated choroid plex us cysts are seen equally frequently in male and female fetuses adds to bas ic information about such a common sonographic finding.
