Clinical features of the fetus. (A) Ultrasonography showed that there were echoes of the sixth toe on the lateral side of the little toe of both feet and the lateral side of the little finger of both hands, with a size of about 0.6*0.4 cm, and no obvious bony structure in them. (B) MRI showed a finger-like signal shadow on the outside of the right little finger, while the number of fingers on the left hand was not clear due to the position of the fetus. Six toe-like signal shadows were seen on both feet.
