Cervical myelomeningoceles (CMMC) are a less common but distinct subgroup of myelomeningoceles. Their embryology and clinical characteristics vary from the more common thoracolumbar variant. Only a few small series have been published addressing this lesion in the literature with the largest one of them addressing nine patients. The authors present one of the largest series of cervical myelomeningoceles, review their embryology, clinical features, and their management strategies. ⋯ Cystic dysraphisms of the cervical differ embryologically, clinically, and structurally from thoracolumbar meningomyelocele and have a more favorable outcome. A good pre operative evaluation is recommended to assess any associated anomalies and identify the internal structures. Surgery excision of these lesions with intradural exploration of the sac to release any potential adhesion bands as well as other associated anomalies is recommended.

The authors present the case of a 5-year-old child with severe traumatic brain injury in whom decompressive hemicraniectomy was performed for progressive increased intracranial pressure (ICP) unresponsive to medical treatment. Data from ICP and cerebral tissue oxygenation monitoring in the contralateral hemisphere were recorded, which demonstrated the immediate and delayed mechanical and physiological changes occurring after bony and dural decompression. ⋯ The role of the procedure and that of the monitoring approach are discussed.

Surgical revascularization for moyamoya disease prevents cerebral ischemic attacks by improving cerebral blood flow (CBF). It is undetermined, however, how rapid increase in CBF affects ischemic brain at acute stage, especially in children. ⋯ We demonstrated, for the first time, that delayed focal neurological deficit after STA-MCA anastomosis can be caused by focal hyperperfusion in childhood moyamoya disease.

We evaluated whether the presence of lacunar skull deformity (LSD) with myelomeningocele is a predictive factor for subsequent hydrocephalus development. ⋯ Adding to the ventriculomegaly at birth, the presence of LSD alerts to the necessity to monitor these infants closely to determine the necessity for VPS placement.

Antibiotic-impregnated shunt (AIS) systems have been designed to prevent the colonization of shunt components by skin flora that occurs at surgery. Although such systems may decrease the incidence of early shunt infections (those occurring within 6 months of shunt placement), it is unclear if such exposure to prolonged antibiotics leads to an increased incidence or virulence of late shunt infections (those occurring later than 6 months after shunt placement). In this study, the authors evaluate the incidence of late shunt infection after the introduction of an AIS system in a pediatric hydrocephalus population. ⋯ Although concern exists that AIS systems may delay shunt infections or even increase the rate or virulence of such infections, introduction of such catheters into a pediatric hydrocephalus cohort does not significantly increase incidence of late CSF shunt infection compared to historic controls.
