The scan revealed nonvisualization of the bilateral femur bones [Figure 1].
Antenatal ultrasound at 18-20 weeks at the level of the legs shows normal-appearing bilateral tibia and fibula of the right side (arrow).

The bilateral tibia and fibula were within normal limits as per gestational age [Figure 2]. 3D and 4D ultrasounds also clearly demonstrated the same abnormality [Figure 3].

The bilateral tibia and fibula were within normal limits as per gestational age [Figure 2]. 3D and 4D ultrasounds also clearly demonstrated the same abnormality [Figure 3].
3D ultrasound image at the level of lower limbs clearly demonstrates nonvisualized thigh (asterisk) with a normally developed leg (arrow).

Fetal MRI was performed, which also showed similar findings [Figure 4].
Another 3D ultrasound image at the level of lower limbs demonstrates normally developed both legs (tibia and fibula, denoted by thin arrows) directly articulating with the pelvis (asterisks) with nonvisualization of bilateral thighs (femurs). Note is made of right-sided club foot (bold arrow).

The antenatal findings were confirmed postnatally both clinically [Figure 5] as well as with an X-ray infantogram [Figure 6].
Fetal MRI has done at 32-33 weeks at the level of the fetal pelvis, shows nonvisualization of femur with the tibia and fibula (arrow) in close proximity with the acetabulum (asterisk).
