The management of intracranial dural arteriovenous fistulas (DAVFs) is complex and may require a combination of various treatment techniques. Endovascular embolization has recently emerged as the primary definitive treatment modality. However, an increasing body of literature has supported the use of stereotactic radiosurgery as the sole therapeutic modality or in combination with embolization and/or surgery. We review the rationale, results, and complications of stereotactic radiosurgery for intracranial DAVFs.

The impact of three-dimensional (3D) dose delivery accuracy of C-arm linacs on the planning target volume (PTV) margin was evaluated for non-coplanar intracranial stereotactic radiosurgery (SRS). A multi-institutional 3D starshot test using beams from seven directions was conducted at 22 clinics using Varian and Elekta linacs with X-ray CT-based polymer gel dosimeters. Variability in dose delivery accuracy was observed, with the distance between the imaging isocenter and each beam exceeding 1 mm at one institution for Varian and nine institutions for Elekta.

Introduction: Advances in modern therapies have improved outcomes for patients with melanoma brain metastases (MBM), though prognosis remains poor. The optimal treatment strategy for patients who do not meet clinical trial inclusion criteria is unclear.
Methods: This study included all patients with MBM diagnosed in Denmark between 2015 and 2022, identified through the Danish Metastatic Melanoma Database (DAMMED) and local surgical and radiotherapy records.

Purpose: Even with modern immobilisation devices, some amount of intrafraction patient motion is likely to occur during stereotactic radiosurgery (SRS) delivery. The aim of this work was to investigate how robustness of plans to intrafraction motion is affected by plan geometry and complexity.
Methods: In 2018, the Trans-Tasman Radiation Oncology Group conducted a multiple-target SRS international planning challenge, the data from which was utilised in this study.

Background: Stereotactic radiosurgery (SRS) is a well-established option for the management of intracranial tumors, including meningiomas. Although valued for its low invasiveness and precision, it still carries a risk of complications. Communicating hydrocephalus is a serious, albeit rarely reported, complication of SRS.

Background: Even a gross total resection of a benign epidermoid tumor (ET) carries a high risk of recurrence. The management strategy mostly involves redo surgical excision but at a significant cost of morbidity and mortality. The role of adjuvant radiation therapies in this scenario is still undefined.
