Scoliosis is a three-dimensional spinal deformity for which surgery may be indicated when patients experience severe pain, curve progression, or progressive disability. Operative treatment has conventionally involved extensive posterior stabilization, either alone or in combination with anterior release procedures. Anterior-only approaches have a more limited role, but they should be considered in the appropriate setting when addressing this disease. ⋯ Technological advances, including minimally invasive thoracic access as well as evolving instrumentation, may minimize the stated disadvantages and expand the scope of scoliosis cases that may be treated by anterior-only approaches. Hence, the enhanced corrective ability and biomechanical advantages of the anterior column can be used in the treatment of these patients. Although the indications for anterior-only strategies in scoliosis remain limited, such operations should be considered in the appropriate setting when addressing spinal deformity.

Predictors of peritumoral edema after stereotactic radiosurgery of supratentorial meningiomas.
Anecdotal evidence suggests that radiosurgical ablation of parasagittal meningiomas may be associated with increased risk of subsequent edema. Potential predictors of postradiosurgical peritumoral edema, including parasagittal tumor location, tumor size, and treatment dose, were evaluated. ⋯ Patients with parasagittal meningiomas are at greater risk of developing peritumoral symptomatic edema after SRS. Close follow-up after SRS may be particularly important in such patients. These results highlight the need to pursue strategies that could decrease the incidence of postradiosurgical edema in patients with parasagittal meningioma.

Congenital thoracolumbar spinal deformities are a common and frequent reason for referral to spine surgeons. Neurosurgeons also treat many neurological diagnoses which may result in a progressive spinal deformity, such as scoliosis. ⋯ Advances in the field of spinal deformity correction now allow us to better treat individuals with these types of deformities. It is important for the practicing neurosurgeon to be knowledgeable of surgical and nonsurgical treatments of patients with congenital thoracolumbar spinal deformities in order to better understand which patients will ultimately progress and necessitate surgical treatment.

Case Reports Comparative Study
Results of endovascular treatment of traumatic intracranial aneurysms.
To present results of early angiographic diagnosis and endovascular treatment of traumatic intracranial aneurysms (TICA). ⋯ Early angiographic diagnosis with immediate endovascular treatment provided an effective approach for TICA detection and management. Endovascular therapy is versatile and offers a valuable alternative to surgery, allowing early aneurysm exclusion with excellent results.

Radiological findings and clinical course of conus lipoma: implications for surgical treatment.
A significant variety in morphology of conus lipomas may underlie differences in clinical presentation of the patients and controversy in surgical management. We retrospectively studied 58 patients with conus lipomas at our institutions. The purpose of this study was to infer the clinical course from the radiological findings and to provide information for decision-making in planning for surgical treatment. ⋯ This study demonstrates that the location and morphology of conus lipomas influence the neurological presentation of the patients. Early prophylactic surgery is a reasonable treatment option if early deterioration is predicted by imaging studies.
