Case report
A 38-year-old woman (G2P1) was referred to our antenatal unit at 32 weeks of her pregnancy. Her medical history was non-contributive. Our sonographic examination of the fetus revealed following findings:
-
Short forearm of the right upper limb with missing radius (Image 1);
-
Radial deviation of the right hand with only rudimentary thumb (Image 2, 3, 4, and 5);
-
Normal appearance of the left upper limb and spine.
Fetal karyotyping was normal (46, XX). A spiraled CT scan was also done and confirmed the finding (Image 6). The sonographic features were concordant with diagnosis of the radial ray aplasia.
The baby was delivered vaginally and the diagnosis was confirmed.
Images 1, 2: The image 1 compares normal left forearm (left half of the image - normal ulna can be seen) and the abnormal right forearm with missing radius (right half of the image - the ulna is shorter than the left one). The image 2 shows the left hand of the fetus with absent thumb.
