Ambiguous genitalia:

3D ultrasound image

 Ultrasound images of this 23 week fetus reveal prominent labia (or small scrotum) and a large clitoris (or a small penis). The labia appeared partially fused. Fetal karyotyping is required in such cases along with serum 17- Hydroxy progesterone level assay. Fetuses with ambiguous genitalia may be genetic females (XX chromosome) or genetic males (XY chromosome).

Fetal intra-abdominal cyst:

sonographic image of fetal abdominal cyst

 Ultrasound images of this fetus reveal a large cystic lesion in the abdomen. It appears to be separate from the fetal kidneys as well as the stomach bubble. The cystic mass also does not appear to arise from the urinary bladder. It lies in the right lumbar region of the fetal abdomen. The possibilities include fetal mesenteric cyst or enteric duplication cyst. Images courtesy of Dr. Vikas Arora, Ferozepur, India.

Occipital encephalocele:

These ultrasound images show occipital encephalocele in a 19 week old fetus. The encephalocele is produced by a defect in the occipital calvarium and upper cervical region of the fetal spine. The typical “cyst within a cyst” appearance is also well seen. The occipital mass in such cases would contain dystrophic cerebellum and possibly the upper part of spinal cord.

Cyst of the umbilical cord:

B-mode image of cord cyst

 

These B-mode and color Doppler ultrasound images show a cystic mass of the umbilical cord. Color Doppler sampling of the cord shows absence of flow within the cyst, which suggests it is non-vascular. This rules out the possibility of umbilical cord varix (a cystic dilatation of the umbilical vein). The possibilities that now need to be considered include:                    

a)       True cyst of the cord

b)      Pseudocyst of the cord or false cysts.

Unlike true cysts, pseudocysts do not have an epithelial lining.

The images show the cyst to be located near the fetal end of the cord.

As both of these types of cysts are associated with fetal anomalies, karyotyping and level 2 sonography may be needed.

3-D ultrasound images of Macroglossia:

 The ultrasound images above show the hypertrophied fetal tongue (macroglossia), protruding outside the oral cavity, beyond the alveolar ridge, in this 29 week old fetus. Macroglossia may be associated with a number of other fetal congenital anomalies, including Beckwith-Wiedman syndrome, omphalocele, nephromegaly, cystic kidneys and
placentomegaly.

3D-ultrasound images of anencephaly:

3D ultrasound image showing fetus with anencephaly

sonography of anencephaly

These are 3-D sonographic images which show anencephaly in a 2nd trimester fetus, with its typical features. The cranial vault is absent with rudimentary brain tissue. The surface rendering of 3-D sonography, reveals prominent eyeballs and a typical frog-like appearance, due to the absent cranium.

On the lighter side:

Here are some 3-D images by Dr. Arun Mahajan which depict various moods of the normal fetus:
