“…Several associated anomalies have been described, such as agenesis of corpus callosum, hemihypertrophy and frontoethmoidal encephalocele. If no associated anomalies are present, unilateral hydrocephalus has a good prognosis even when discovered in utero: adequate treatment of CSF disturbance usually allows good neurological outcome [ 7 , 8 ].…”

Congenital hydrocephalus and ventriculomegaly can be diagnosed reliably with prenatal ultrasound and Magnetic Resonance Imaging (MRI). Unilateral hydrocephalus is uncommon, and the prognosis depends on etiology and postnatal management. Here, we present a case of a 32-years-old woman with prenatal diagnosis of unilateral hydrocephalus associated with stenosis of the foramen of Monro. Unilateral hydrocephalus is an uncommon feature that can be detected prenatally on ultrasound and MRI. In case of isolated stenosis of the foramen of Monro prognosis is good.

“…Therefore, cranial sonography is a valuable tool which can aid in timely surgical interventions for cases of progressive ventriculomegaly. Previously, ventriculoperitoneal (VP) shunting was the preferred surgical strategy to alleviate symptoms of FOM occlusion (19). However, this procedure can result in complications such as mechanical malfunction and infection.…”

“…One study showed that most patients with shunt failure required re-shunting before reaching 2 years of age (21). In the past, isolated septum pellucidotomy was not a routine procedure, although it was sometimes performed together with foraminoplasty or in addition to third ventriculostomy (19). In current practice, minimally invasive endoscopic procedures are the commonly used management procedures.…”

BackgroundHydrocephalus is a brain abnormality frequently encountered in neonates. There are several known etiologies of hydrocephalus, which can be classified as either congenital or acquired. Occlusion of the foramen of Monro (FOM) is a cause of hydrocephalus and can be either congenital or secondary to various disorders. Idiopathic obstruction of the FOM presenting as prenatal ventriculomegaly is extremely rare but has been reported.Case presentationWe present the case of a preterm newborn with severe bilateral hydrocephalus due to FOM occlusion in the prenatal period. Although the neonate had normal head circumference and no clinical symptoms after birth, brain sonography revealed progressive ventriculomegaly. Further image revealed bilateral ventriculomegaly with normal-sized third and fourth ventricles. We suspected a complete obstruction of the right and a partial obstruction of the left of the FOM. The neonate underwent endoscopic septostomy and foraminotomy, resulting in improvement.ConclusionWe report a case of preterm FOM occlusion in the youngest and smallest neonate to date. Endoscopic septostomy and foraminotomy were performed in order to avoid ventriculoperitoneal shunt-related complications, highlighting the viability of endoscopic procedures which should be the primary treatment in preterm neonates with FOM occlusion.
