The ultrasound finding described as a flattened occiput and a strawberry-shaped skull is associated with which chromosomal condition?

• A. Strawberry shape
• B. Anencephaly
• C. Occipital horn dilation
• D. Microcephaly

Answer: (A)

A strawberry-shaped skull on fetal ultrasound is a classic sign pointing to Edwards syndrome (Trisomy 18). The description of a flattened occiput with small, rounded calvarial bones creates a contour that resembles a strawberry. This particular skull shape is strongly associated with Trisomy 18 and helps raise suspicion for that chromosomal condition during ultrasound examination. Other options describe different conditions or features that don’t produce the strawberry skull pattern, so they don’t fit this specific association.
