We report on an Italian boy, born to normal and nonconsanguineous parents with a prenatal diagnosis of ventriculomegaly and subependymal glial heterotopias. At birth bilateral macrostomia was diagnosed without other evident facial anomalies. Magnetic resonance imaging (MRI) showed triventricular hydrocephalus and aqueductal stenosis and confirmed the nodules of glial heterotopia. The bilateral macrostomia was surgically corrected with the vermilion square flap method and W-plasty technique and follow up MRI at 6 months showed mild increase of ventricular dilatation without signs of active hydrocephalus. The association between macrostomia and hydrocephalus has been reported only in rare cases of complex malformative syndromes but never with isolated macrostomia.

Craniosynostosis is defined as the process of premature fusion of one or more of the cranial sutures.  It is a common condition that occurs in about 1 to 2,000 live births. Craniosynostosis may be classified in primary or secondary. It is also classified as nonsyndromic or syndromic. According to suture commitment, craniosynostosis may affect a single suture or multiple sutures. There is a wide range of syndromes involving craniosynostosis and the most common are Apert, Pffeifer, Crouzon, Shaethre-Chotzen and Muenke syndromes. The underlying etiology of nonsyndromic craniosynostosis is unknown. Mutations in the fibroblast growth factor (FGF) signalling pathway play a crucial role in the etiology of craniosynostosis syndromes. Prenatal ultrasound`s detection rate of craniosynostosis is low. Nowadays, different methods can be applied for prenatal diagnosis of craniosynostosis, such as two-dimensional (2D) and three-dimensional (3D) ultrasound, magnetic resonance imaging (MRI), computed tomography (CT) scan and, finally, molecular diagnosis. The presence of craniosynostosis may affect the birthing process. Fetuses with craniosynostosis also have higher rates of perinatal complications. In order to avoid the risks of untreated craniosynostosis, children are usually treated surgically soon after postnatal diagnosis.

Rhombencephalosynapsis (RES) is a rare cerebellar malformation characterized by congenital fusion of the hemispheres and absence of the vermis. This condition is associated with developmental delay, seizures and involuntary head movements. Although the clinical and imaging aspect of this condition have been thoroughly investigated in the adult, prenatal diagnosis remains still a challenge in the modern Fetal-Maternal Medicine. Here we report our experience with 3 cases and review the current literature as well, focusing specifically on the obstetric imaging as well as on the prenatal diagnosis and management of this rare condition. RES should be considered in the differential diagnosis when absence of the vermis in the Posterior Fossa (PF) is suspected at prenatal Ultrasound Sonography (US), especially when ventriculomegaly or other Central Nervous System (CNS) anomalies are detected. A complete anatomical workup is necessary in these cases. Magnetic Resonance Imaging (MRI) remains to be the imaging modality of choice in confirming the diagnosis.
