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.

    Ultrasonography is an ultrasound-based diagnostic imaging technique used to visualize subcutaneous body

    structures including tendons, muscles, joints, vessels and internal organs for possible pathology or lesions.

    Obstetric sonography is commonly used during pregnancy and is widely recognized by the public. There is a

    plethora of diagnostic and therapeutic applications practiced in medicine.
