The majority of complications following (LITT) therapy occur in the early postoperative period, with few long-term complications being reported. ⋯ We hypothesize chronic gliosis following LITT therapy results in blood vessel sclerosis leading to blood-brain barrier-breakdown and delayed cyst formation. These findings support the need for long-term surveillance of patients treated with LITT.

The criterion standard for the treatment of newly diagnosed primary central nervous system lymphoma (PCNSL) remains high-dose chemotherapy in conjunction with palliative whole-brain radiotherapy; however, there may be a role for novel combined approaches in immunocompromised patients. ⋯ The criterion standard for treatment of newly diagnosed PCNSL remains high-dose chemotherapy in conjunction with palliative whole-brain radiotherapy; however, there may be a role for novel combined approaches using chemotherapy, HAART, and GKRS to have a positive impact on survival rates of PCNSL related to AIDS.

The supraorbital keyhole approach through an eyebrow incision has been a potentially less invasive approach as an alternative to the standard pterional craniotomy. We aimed to review procedures for anterior and middle cranial fossa lesions and identify lessons learned from addressing various pathologies through this approach. ⋯ The supraorbital keyhole approach may be safely used for various lesions within the anterior and middle cranial fossa. The effectiveness and limitations of this approach and possible complications are discussed. This is a valuable approach for selected patients.

Cervical stenosis with myelopathy caused by ossification of the ligamentum flavum is relatively rare. Surgical treatment is the preferred option. Previous surgical procedures usually require assisted internal fixation, and some problems may occur, such as large trauma, intraoperative bleeding, wound infection, and internal fixation failure. The aim of this paper is to introduce a new minimally invasive surgical procedure for the treatment of upper cervical spinal stenosis complicated with myelopathy. ⋯ PECLD is an effective method for treating cervical stenosis associated with myelopathy because of ossification of the ligamentum flavum. It has the advantages of smaller trauma, less bleeding, shorter postoperative hospital stay, and faster recovery. Taken together, this minimally technique can be considered as a good alternative to traditional open surgery.

The revised World Health Organization classification of central nervous system tumors, published in 2016, has recognized the H3 K27M mutation as a critical genetic signature defining a new group of infiltrative astrocytomas designated as diffuse midline glioma, H3 K27M mutant. Although most H3 K27M mutations arise in the setting of diffusely infiltrative tumors, there are rare reports of compact tumors with low-grade histologic features harboring this mutation. The prevalence and clinical significance of this mutation in pilocytic astrocytomas remain unclear. ⋯ Stereotactic biopsies may undergrade some adult thalamic pilocytic astrocytomas. Therefore, we recommend that all these tumors be evaluated for the H3 K27M mutation. Further, we think H3 K27M-mutant thalamic pilocytic astrocytomas require aggressive multimodality treatment and these treatments should be guided by the molecular findings, as opposed to the histologic ones.
