    Abstract A mature cystic teratoma is a mass with heterogeneous appearance, consisting of adult tissue with two or three layers: endoderm, mesoderm, and ectoderm. It is a rare, benign transformation of somatic tissue most commonly found in the sacrococcygeal region and may resemble an uncomplicated spina bifida on prenatal ultrasonography. In this case report, we describe a female newborn with an extremely rare mature cystic teratoma in the thoracolumbar region. She presented prenatally with a preliminary diagnosis of meningomyelocele, diastematomyelia, and Chiari II malformation and a possible teratoma. However, a mass containing solid glandular tissues and bony calcifications approximately 3 × 4 cm in size was observed in the thoracolumbar region upon birth. During surgical resection, no nerve roots were found in the associated meningocele. The patient retained full lower body function postoperatively following surgical excision of the thecal sac and teratoma.

    Abstract A previously healthy male presented at age 5 years with recurrent abdominal pain that occurred diffusely. The pain was severe enough to cause episodic screaming, especially at night with spontaneous resolution. The patient was initially treated for constipation but when motor symptoms began to develop, imaging revealed the cause of his pain to be a spinal cord mass. The tumor was treated with steroids, and biopsy confirmed a grade II spinal cord astrocytoma. We describe this unusual presentation of a pediatric spinal cord astrocytoma and review the literature.

    Abstract Aggressive hemangioma is a rare vertebral lesion in pediatric patients which can present with deteriorating neurological function. It can mimic malignancy on imaging, particularly as it regularly has an extrasosseous soft tissue component. We present a case of a 13-year-old male who presented with a three month history of lower extremity weakness that was found to have an infiltrative mass at T10 with associated cord compression from epidural extension of the lesion. In this report we review the characteristic imaging findings associated with aggressive hemangioma, including its appearance on read-out segmented diffusion-weighted images. It is imperative that radiologists who interpret studies of children be aware that this lesion exists and what it looks like, as it can be associated with massive hemorrhage if encountered unexpectedly during surgery.

    Abstract Objective: Myelomeningocele is a defect that typically is repaired surgically within the first few days of life in developed countries to minimize the risk of meningitis. If left unrepaired, these children may survive to have their meningocele sac epithelialize. The surgical reduction and closure of an epithelialized myelomeningocele represents a unique challenge for the neurosurgeon because it requires a modification of the typical closure technique.
    Methods: Our 10 years' experience in 97 patients with the delayed (>6 months) repair of myelomeningoceles formed the basis of this report.
    Results: We present repair techniques in a child with a myelomeningocele that was not repaired at birth and presented a surgical challenge.
    Conclusion: Delayed closure of myelomeningoceles is facilitated by lessons learned from our surgical experience during a medical missions to Guatemala.

    Abstract Craniosynostosis affecting the lambdoid suture is uncommon. The definition of lambdoid craniosynostosis solely applies to those cases demonstrating true suture obliteration, similar to other forms of craniosynostosis. In patients presenting with posterior plagiocephaly, true lambdoid craniosynostosis must be differentiated from the much more common positional molding. It can occur in a unilateral form, a bilateral form, or as part of a complex craniosynostosis. In children with craniofacial syndromes, synostosis of the lambdoid suture most often is seen within the context of a pansynostotic picture. Chiari malformations are commonly seen in multisutural and syndromic types of craniosynostosis that affect the lambdoid sutures. Posterior cranial vault remodeling is recommended to provide adequate intracranial volume to allow for brain growth and to normalize the skull shape. Although many techniques have been described for the correction of lambdoid synostosis, optimal outcomes may result from those techniques based on the concept of occipital advancement.

    Abstract Objectives: The aim of this study is to provide an overview of each device, discuss conditions that may predispose to the requirement of both devices, and consider pre- and post-operative issues arising from the co-existence of advanced technologies. In addition, relevant surgical anatomy and technique in the placement of both cochlear implant (CI) after ventriculoperitoneal shunt (VPS) and VPS after CI are reviewed.
    Methods: Review of literature.
    Results: Issues relevant to CI and VPS include predisposing conditions, magnetic resonance imaging compatibility, infectious risk, surgical technique, complication management, and a host of other issues.
    Discussion: Patients with hydrocephalus and severe-to-profound hearing loss are a unique patient population with unique pre-, intra-, and post-operative issues. Thorough understanding of the indications, radiology, anatomy, technology, and potential complications can allow for these patients to achieve the full benefit of these lifechanging surgeries.

    Abstract Background: Patients frequently present to the emergency department (ED) for evaluation of cerebrospinal fluid (CSF) shunt malfunction, often requiring urgent management. A typical evaluation in the emergency room setting includes a thorough history and physical examination, noncontrasted head computed tomography (CT), shunt series, and occasionally a ventricular shunt tap.
    Case description: We present the case of a 53-year-old male who initially presented to the ED in acute status epilepticus. His history was notable for seizures and multiple craniectomies and cranioplasties with subsequent placement of a ventriculoperitoneal shunt secondary to traumatic brain injury. Imaging in the ED suggested possible shunt failure. No previous imaging was available for comparison, and therefore a ventricular shunt tap was attempted. Initially, the tap could not be performed, as the shunt was not palpable secondary to the thickness of his scalp and location of the reservoir near his complex cranial reconstruction site. We report, for the first time, the utility of emergency ultrasound (EUS) to aid in such an encounter.
    Conclusion: EUS revealed the exact location of his shunt reservoir, and therefore enabled the shunt tap, which ultimately led to the discovery of the patient's proximal shunt failure in a setting that may have otherwise been missed. The patient underwent urgent shunt revision with a good outcome.

    Abstract Purpose: Desmoplastic fibromas are primary bone tumors that seldom occur in the cranial bones. Furthermore, reports of desmoplastic fibromas of the skull in children are exceedingly rare. Although desmoplastic fibromas are histologically benign, they are locally aggressive and have a propensity to reoccur. Their radiographic appearance may mimic other more common central nervous system and bone neoplasms. There are only 19 reported cases of desmoplastic fibroma of the cranium in the literature, and only seven occurred in the pediatric age group. We present a case report of an 11-year-old female patient with a desmoplastic fibroma of the parieto-occipital region and review the literature.
    Case report: An 11-year-old female presented to the craniofacial clinic complaining of intermittent pain and a soft mass in the occipital region. There was a distant history of trauma to the region that did not require medical intervention. Computed tomography imaging revealed a lytic bone lesion overlying the sagittal sinus in the parieto-occipital region. Surgical resection with wide margins and immediate autologous reconstruction was performed. Pathological analysis revealed a desmoplastic fibroma. At 4 months of follow-up, no recurrence has been noted.
    Conclusion: Desmoplastic fibroma of the cranium is rare. Complete surgical resection with careful follow-up is the treatment of choice.
