Giant Intracranial Cyst Reduction after Shunting

A male newborn was admitted with in utero diagnosed giant intracranial cyst. The cyst was located in the left cerebral hemisphere. In utero ultrasound findings suggested extreme ventriculomegaly of the left lateral ventricule. At admission, the newborn had discrete right-sided motor weakness and macrocephaly (haed circumference at the 98th percentile) with diastasis of coronal, sagittal and lambdoid sutures. The MR images show a giant cyst of the left cerebral hemisphere with a very thin cerebral mantle over the frontal, parietal and temporal lobes, a minimal rightward shift and expansion of the left side of the calvaria, unusually low positioned basal ganglia, herniation of the ventricle into the posterior fossa and compression with caudal displacement of the vermis and cerebellar hemispheres. After insertion of a cystoperitoneal shunt (medium pressure valve)successive ultrasound controls revealed good regression of the cyst volume. A CT scan performed 1 year after shunting showed good position and function of the inserted shunt with excellent recovery of the cerebral mantle over the cyst wall. At 1 year of age, the child has no visible neurogical deficits.
