Case report

A 32-year-old primigravida (G1P0) patient was referred to our department at 30 weeks for a suspected anomaly of the fetal head. Her history was unremarkable.

An examination was done with a Voluson I.

Our examination revealed the following findings:

Images 1,2: Ultrasound Images show, in the axial section of the cranium, a midline pear-shaped, well-defined fluid-filled structure measuring 28 x 16 mm (indicated by arrows). Behind the mass revealed a tubular anechoic prolongation. Doppler shows blood flow within the mass.

Images 3-5: Tomographic Ultrasound Images, in the axial section,  show ectasia of the vein of Galen (EvG), third ventricle (3v)  and septum pelicidum (SP)

Images 6,7: The following images 3D reconstruction and power Doppler, In the coronal section, show ectasia of the vein of Galen (EvG), located posteriorly above the thalamus, and straight sinus (StrS), confluence of the sinuses (CS), vermis (vc).

Image 8:  Tomographic Ultrasound Images with power Doppler shows arterio - venous connections (arrows) between the circle of Willis and vein of Galen ectasia.

Images 9-14: The 3D Power Angio reconstruction demonstrates connection feeder and draining vessels (arrows)  of the vein of Galen ectasia and sinuses of brain (ts – transverses sinus, sps – superior petrosal sinus) We did not detect any other associated findings.

The newborn was delivered at 39 weeks (male, 2298 g, 50 cm, 4020 g, 55 cm, Apgar score: 7, 8). Postnatal course of the newborn was normal.  The infant was alive in 3 month (then we lost contact with his parents).
