Fibroadenoma and fibroadenosis of breast:

On http://www.ultrasound-images.com/breast.htm
I have just posted some nice sonographic images of a rather gray area in the field of breast imaging. There is almost no radiological literature on the subject of fibroadenosis of the breast, both on the internet and in print. At the link above are ultrasound images of both fibroadenoma and fibroadenosis of breast. What I have gathered is that fibroadenosis is a more or less "normal" nodularity of the breast which is usually self limiting (can disappear over a period of a few weeks to months). Clinically fibroadenosis may cause a little tenderness in the breast, with or without palpable nodules (which may be visualized on sonography). However, fibroadenoma of breast is a well established clinical and radiological entity. Fibroadenoma presents as a palpable (often "slippery") small nodule, well seen on ultrasound.
Here is a typical image of fibroadenoma.... (see above).

Another case of ectopia cordis:

This is one of the best cases of ectopia cordis I have seen. The short ultrasound (sonographic) video of ectopia cordis shows the pulsating heart, outside the thoracic cavity, in both B-mode and Color Doppler imaging. Ultrasound video courtesy of Dr. Dilraj Gandhi, MD, India.

Placental calcification

Calcification of placenta is a sign of normal degenerative changes taking place in the placenta. This usually happens in the 3rd trimester and is usually of little or no clinical significance. However, if seen earlier (2nd trimster) it might signify placental aging and abnormal degenerative changes. In the ultrasound video attached, there is extensive calcium deposition of the placenta on the maternal surface, (or basal part). Such calcific changes of the placenta do not indicate any placental pathology. See: sonography of placenta for more images and cases.

Hydrocephalus in fetus: aqueductal stenosis:

Hydrocephalus is a common disease during intrauterine life. Almost 20 % of fetal hydrocephalus is caused by aqueductal stenosis. In the ultrasound image and sonographic video of the fetal head, above, the lateral ventricles and the upper part of the aqueduct of Sylvius (or cerebral aqueduct) are markedly dilated. The 4th ventricle does not appear to be enlarged suggesting obstruction to CSF flow at the level of the cerebral aqueduct. This is called aqueductal stenosis. Other causes of hydrocephalus include Dandy Walker malformation. Ultrasound image and video of aqueductal stenosis are courtesy of Dr. Martin Horenstein, Argentina.

Sonography in cervical insufficiency:

This ultrasound image of gravid uterus shows the cervix measuring 1.1 cms. in length (shortening) with dilatation (3mm.) of the internal os. The image was taken using the transvaginal route, using a Toshiba Xario ultrasound system. Dilatation with effacement of the cervix are diagnostic of cervical insufficiency. The management in this case would mean cervical cerclage.

From the virtual 3D image to real life size models of the fetus

Just saw this interesting link: http://www.dailymail.co.uk/sciencetech/article-1195703/The-stunning-new-technology-allows-parents-hold-life-size-model-unborn-child.html
It seems a PhD student Jorge Lopes has found a method to create 3D life size plaster models of the fetus as seen on 3D Ultrasound and MRI imaging. The replicas can help the mother identify and bond more intensely with the baby in the womb. Maybe, in the not too distant future, we may see Obstetricians and radiologists prepare plaster models, as easily as thermal print images of the fetus!!
