I had two "soft" markers on my 16 week level 2 ultrasound; choroid plexus cyst and an absent pinky bone. Echogenic intracardiac focus (EIF) is a relatively common sonographic observation that may be present on an antenatal ultrasound scan. Partial callosal dysgenesis, interhemispheric glioependymal cyst, and cortical dysplasia (microscopic findings). Confirmation of the initial diagnosis requires histopathological confirmation of the glioependymal nature of the membrane structure and exclusion of malignant or infectious cysts. Aside from advanced maternal age, two of the most common reasons for referral for a genetic sonogram are fetal choroid plexus cysts (CPCs) and echogenic intracardiac foci (EIFs). In about 1 to 2 percent of normal babies - 1 out of 50 to 100 - a tiny bubble of fluid is pinched off as the choroid plexus forms.
