While single-fraction Gamma Knife radiosurgery (GKRS) has shown efficacy in managing vestibular schwannomas (VSs), some concerns have been raised regarding its safety profile, particularly in the context of hearing preservation. Hypofractionation has emerged as a promising approach to improving the safety profile. This retrospective, single-institution study evaluated patient outcomes following hypofractionated GKRS (hf-GKRS) for treatment-naïve Koos grade IV VSs.

- MRI is a crucial tool for planning stereotactic radiosurgery (SRS), but it often contains distortions that can affect treatment outcomes.
- This study analyzed 26 MRI datasets for metastatic brain tumors and used software to correct distortions, finding notable discrepancies between uncorrected and corrected tumor volumes.
- The results emphasized the importance of using corrected MRI for SRS plans, as even small distortions can lead to significant treatment inaccuracies.
Background: Eagle syndrome, an uncommon condition, causes symptoms due to neural and/or vascular compression from an elongated styloid process or calcified stylohyoid ligament and can also complicate other planned surgical procedures.
Observations: A 42-year-old female with loss of balance, dizziness, and ataxic gait underwent cranial magnetic resonance imaging (MRI), revealing a right-sided Koos grade IV vestibular schwannoma. Initially, a retrosigmoid craniotomy for tumor resection was planned.
Glossopharyngeal neuralgia (GPN) is an unusual disorder causing severe, brief pain episodes in the areas supplied by the glossopharyngeal nerve. Initial treatment involves medications like carbamazepine, but if these are ineffective or cause side effects, interventional pain management techniques or surgery may be considered. Gamma Knife radiosurgery is becoming popular in managing GPN due to its lower risk of complications than surgical interventions like microvascular decompression or rhizotomy.

- Meningiomas in children are rare and have different characteristics compared to adults, with limited existing research on stereotactic radiosurgery (SRS) for this group.
- A study was conducted on 57 pediatric patients treated with single-fraction SRS, evaluating tumor control, complications, and neurological outcomes over a median follow-up of 69 months.
- Results showed high tumor control rates (85.9%) with minimal new neurological deficits (3.5%) and some adverse radiation effects, indicating that SRS is a promising treatment option for difficult-to-treat pediatric meningiomas.
Background: The management of craniopharyngiomas is challenging, usually requiring multidisciplinary care. Gamma Knife radiosurgery (GKRS) is an essential technique for residual/recurrent craniopharyngiomas.
Objective: To evaluate the efficacy of frameless hypofractionated GKRS (hfGKRS) for craniopharyngioma and factors which affect tumor control and complications.
