Review Case Reports
Radiation-induced spinal cord cavernous malformations associated with medulloblastoma: a case report and literature review.
Radiation-induced spinal cord cavernous malformations (CMs) are rare pathologies compared with radiation-induced cerebral CMs. We present a case of a radiation-induced spinal cord CM developed 31 years after radiation therapy for medulloblastoma. ⋯ Radiation-induced spinal cord CMs should be recognized as a possible late adverse effect in patients treated with radiation therapy for medulloblastoma.

Superior petrosal sinus (SPS) dural arteriovenous fistulas (DAVFs) are a common subtype of tentorial DAVFs that often require microsurgical treatment. We have noted a rare condition involving the presence of a coexisting normal superior petrosal vein (SPV) during surgery for SPS DAVFs; this condition has not been reported in the literature. Identification and preservation of coexisting normal veins are crucial to prevent venous complications. ⋯ An SPS DAVF can coexist with a normal functional SPV, which should be preserved. Use of indocyanine green video angiography is an efficient way to identify the normal SPV.

Comparative Study
Minimally Invasive Approaches to the Lateral Cavernous Sinus and Meckel's Cave: Comparison of Transorbital and Subtemporal Endoscopic Techniques.
Transorbital and subtemporal keyhole approaches have recently been proposed to approach lesions in the lateral wall of the cavernous sinus (CS) and Meckel's cave (MC). Our goal was to compare these approaches and suggest indications for each of them. ⋯ LTOA is a good option to biopsy a lesion in the lateral wall of the CS and LOWA increased the surgical corridor to work with microsurgical techniques. STA and STZA could be better options when wide exposure is necessary, but temporal lobe retraction should be taken into consideration.

With the increasing prevalence of obesity, there is a need to understand the impact of body mass index (BMI) on spine surgery outcomes. Previous literature has reported the influence of obesity in thoracolumbar surgery; however, the impact of obesity on postoperative complications after posterior cervical fusion (PCF) is unknown. ⋯ Our results corroborate that PCF surgery provides significant improvement in neurologic and radiographic outcomes at 12 months after surgery for degenerative cervical spinal disorders. Obesity is a factor to consider in the pre-operative risk assessment.

Distraction-based systems are the most common systems used in the treatment of early-onset scoliosis. In addition to its corrective and deformity progression preventive properties, its vertebral growth stimulation effect has been proved. Recently popularized magnetically controlled growing rods (MCGRs) showed superior results in terms of outcomes and decreased complication rate. Its vertebral growth stimulation effect has not been studied. The aim of the study is to evaluate the vertebral growth stimulation effect in patients treated with MCGR. ⋯ Frequent distractions stimulate longitudinal vertebral growth in vertebrae spanned by MCGR.
