Review Case Reports
A Case of Primary Sellar Paraganglioma: Immunohistochemistry Resource and Review.
Differential diagnosis of sellar masses includes adenoma, meningioma, craniopharyngioma, and metastasis. Primary paraganglioma is seldom considered. We present a case of this unique pathology, review the relevant literature, and compile a compendium of immunohistochemical characteristics for use as a resource. ⋯ Paraganglioma is a rare but potential differential diagnosis to consider when evaluating sellar masses.

Review Case Reports
Lipoma with agenesis of the corpus callosum: about 02 cases with literature review.
Intracranial lipomas are extremely rare fat-containing lesions, comprising 0.1-0.5% of all primary brain tumors. Lipoma of corpus callosum, the commonest variety of all intracranial lipomas (40%-50%), is associated with varying degrees of dysgenesis of corpus callosum and generally remains asymptomatic. ⋯ Lipomas of the corpus callosum are rare, fat-containing asymptomatic lesions, mostly associated with dysgenesis of the corpus callosum. Diagnosis accidentally occurs during diagnostic procedures in case of an encephalic disorder. Magnetic resonance imaging is the most useful modality for a differential diagnosis. Prognosis and symptoms depend on associated malformations. Surgical treatment is mostly not indicated and should be avoided.

To evaluate long-term outcome and reoperation rate for microsurgical bilateral decompression via unilateral approach of lumbar spinal stenosis, a common degenerative spinal disease of the lumbar spine. ⋯ Bilateral decompression via unilateral approach for lumbar spinal stenosis allowed a sufficient and safe decompression of the neural structures, resulting in a highly significant reduction of symptoms and disability, acceptable reoperation rate, and improved health-related quality of life.

Brainstem arteriovenous malformations (AVMs) represent ∼5% of all intracranial AVMs and carry a higher risk of hemorrhage than their supratentorial counterparts. There is a high and near-uniform mortality with initial and recurrent episodes of hemorrhage. Brainstem AVMs may also present symptomatically with focal neurologic deficits or hydrocephalus. ⋯ Embolization may also be used effectively as stand-alone monotherapy for small lesions with 1 or 2 arterial feeders not supplying eloquent parenchyma. Although an extensive evidence base exists for clinical usefulness of stereotactic radiosurgery as monotherapy or in combination with other therapeutic modalities, only a few studies have reported specifically on obliteration and complication rates with monotherapeutic embolization in the treatment of brainstem AVMs. The potential role of embolization as monotherapy for brainstem AVMs is reviewed and discussed.

Meta Analysis
Magnetically Controlled Growing Rod for Early Onset Scoliosis: A Systematic Review and Meta-Analysis.
The goal of the current systematic review and meta-analysis was to explore the utilization of a magnetically controlled growing rod (MCGR) for the treatment of early-onset scoliosis based on eligible studies demonstrating efficacy. ⋯ We demonstrated that MCGR significantly reduced the Cobb angle and thoracic kyphosis while markedly increasing T1-T12 and T1-S1 distances. However, a close comparison of MCGR with CGR reveals more high-quality randomized control trials with a larger sample size and long-term follow-ups are necessary to gather more robust evidence on the efficacy of MCGR for early-onset scoliosis.
