Review Case Reports
Stage IV neuroblastoma with metastatic spread to the mandible in an infant: case report and review of the literature.
Infants and young children with neuroblastoma (NB) may present with metastases. The primary tumor most commonly originates in the abdomen and metastasizes to lymph nodes, liver, and bone marrow. Infants and young children presenting with multiple skull metastases are rare. ⋯ Infants and young children with neuroblastoma rarely present with metastatic lesions to the skull. Even large lesions involving the skull base may be successfully treated with chemotherapy. The use of myeloablative busulfan/melphalan consolidation after induction chemotherapy can decrease the overall metastatic tumor burden. Craniofacial specialists should be aware of treatment options for these young children.

Review
A bibliometric study of the most cited papers in central nervous system arteriovenous malformations.
We performed a bibliometric analysis of studies reporting cases of brain and spinal arteriovenous malformations (AVMs). ⋯ Brain and spinal AVM research was centralized in the United States, has been mainly reported in specific neurosurgical journals, and has been more often related to treatment and natural history and/or clinical features. It is possible that high impact AVM research has been decreasing recently. Because the best approach to these pathological entities remains controversial, research stimulation within this field should be encouraged.

Review Case Reports
Pediatric Rhabdoid Meningioma with extension to the heart, a first case report and literature review.
Meningiomas are the most common benign intracranial neoplasms in adults, but they have a lower incidence in children. Rhabdoid meningioma is a rare subtype of meningioma and is classified as World Health Organization grade III. ⋯ Rhabdoid meningioma is a malignant subtype of meningioma that occurs very rarely in pediatric patients. Additionally, rhabdoid meningioma, when it does occur in pediatric patients, has a high tendency to recur. Radical surgical resection with adjuvant radiotherapy is essential to prolonging survival. This is the first case with extracranial extension to the mediastinal veins and heart.

To analyze the three-dimensional relationships of the operculoinsular compartments, using standard hemispheric and white matter fiber dissection and review the anatomy of association fibers related to the operculoinsular compartments of the Sylvian fissure and the main white matter tracts located deep into the insula. The secondary aim of this study was to improve the knowledge on this complex region to safely address tumor, vascular, and epilepsy lesions with an integrated perspective of the topographic and white matter fiber anatomy using 2D and 3D photographs. ⋯ Complementing topographic anatomy with detailed study of white matter fibers and their integration can help the neurosurgeon to safely approach lesions in the insular region, improving postoperative results in the microsurgical treatment of aneurysmal lesions, insular tumors, or epilepsy surgery.

No widely accepted gold standard for diagnosis of shunt infection exists, with definitions variable among clinicians and publications. This article summarizes the utility of commonly used diagnostic tools and provides a comprehensive review of optimal measures for diagnosis. ⋯ The definition of shunt infection is variable across studies, with CSF culture and/or symptomatology being the most commonly utilized parameters.
