Ultrasound images of placental pathology:

Subchorionic cyst of the placenta:

ultrasound image of chorionic cyst        sonographic image of placental cyst

The two sonographic images above show a cystic lesion of the placenta, just below the placental surface. Few mobile echoes were seen within the lesion. No other abnormalities were seen in the placenta and the fetus. This finding is generally considered to be clinically of little significance. However some reports suggest an association with fetal IUGR (Intrauterine growth retardation). Diagnosis: subchorionic cyst of the placenta. Also known as membranous cyst, chorionic cyst. It is believed to be due to deposition of fibrin in the subchorionic region of the placenta. Images courtesy of Dr. Gunjan Puri, Surat, India.

These ultrasound and color doppler images show the umbilical cord inserting into the placental membranes before reaching the placental tissue proper. This is the typical appearance on sonography, of velamentous insertion of the umbilical cord. Ultrasound images courtesy of Dr. Latha Natrajan, Bangalore, India.
