Review Case Reports
Rosette-forming glioneuronal tumor originating from the spinal cord: report of two cases and literature review.
Rosette-forming glioneuronal tumor (RGNT) is a recently recognized and rarely encountered tumor occurring in the fourth ventricle. RGNT was first described as a new entity for the distinct clinicopathologic features by Komori et.al. in 2002. Histologically, it is composed of 2 distinct features: a glial component, resembling pilocytic astrocytoma, and a neurocytic component forming neurocytic rosettes and/or perivascular rosettes. ⋯ Surgery is the preferred treatment for RGNT. We do not recommend to implement adjuvant radiotherapy and chemotherapy in these patients except the invasive or recurrent tumors. Further examination and routine follow-up should be recommended to estimate the long-term prognosis.

To evaluate the diagnostic value and safety of stereotactic biopsy in acquired immune deficiency syndrome (AIDS) patients with intracranial lesions via meta-analysis. ⋯ Stereotactic biopsy is a safe and effective way of diagnosing intracranial lesions in patients with AIDS. It is helpful for the differential diagnosis and for choosing a suitable therapy. The 4 most common intracranial lesions in patients with AIDS are lymphoma, PML, TE, and HIV encephalitis.

Conventional craniotomy approaches involve substantial soft tissue manipulation that can cause complications. The transciliary supraorbital keyhole approach was developed to avoid these complications. The aim of this review is to evaluate the safety and the effectiveness of the transciliary supraorbital keyhole approach. ⋯ This approach may represent a safe, effective, and less invasive alternative to conventional craniotomies in experienced hands and for a well-selected subset of patients. However, higher-level evidence is needed to confirm this hypothesis.

Pyogenic cerebral ventriculitis is a debilitating form of intracranial infection with an unfavorable outcome as a result of lack of experience in surgical management. ⋯ The results suggest a relatively favorable outcome for management of pyogenic cerebral ventriculitis by NES. The techniques and strategies are practical and should be applied more extensively.

Anterior lumbar interbody fusion (ALIF) and lateral lumbar interbody fusion (LLIF) are commonly used approaches for lumbar spine fusion surgery, each with their own unique advantages and disadvantages. ALIF requires mobilization of the great vessels and peritoneum, and dissection of the psoas muscle in the LLIF technique is associated with postoperative neurologic complications in the proximal lower limb. The anterior-to-psoas (ATP) or oblique lumbar interbody fusion (OLIF) technique is the proposed solution to accessing the L1-L5 levels without the issues encountered with ALIF and LLIF. In this review, the technical nuances, operative outcomes, and complications with the ATP/OLIF technique in the current literature are summarized. ⋯ Early results on the ATP/OLIF technique are promising and warrant further investigation with well-designed prospective randomized studies to provide high-level evidence of the potential advantages over the ALIF and LLIF approaches.
