This article, published in the Journal of Neurological Surgery, explores the use of intraoperative prolactin (PRL) levels as a predictor for remission in patients with prolactin-secreting adenomas. The study involved 12 patients who underwent trans-sphenoidal surgery (TSS) for their adenomas. The results showed that normalization of intraoperative PRL levels was associated with postoperative remission, suggesting that this measurement could be used as an additional factor to predict remission. The authors believe that this method could complement other preoperative and postoperative factors in predicting remission in patients with PRL-secreting adenomas. [Extracted from the article]

This article, titled "Gamma Knife Radiosurgery for Patients with Petroclival Meningiomas: Cohort Study," discusses the use of Gamma Knife radiosurgery (GKR) as a treatment option for petroclival meningiomas (PCM). The study, conducted from 2006 to 2022, retrospectively reviewed the experiences of 36 patients who underwent GKR for PCM. The results showed that GKR was effective and safe, with high tumor control and a low incidence of complications. The study suggests that GKR can be a viable treatment option for selected patients with PCM. [Extracted from the article]

Background: Intraventricular cavernous malformations are unusual intracranial vascular malformations; their deep anatomical location complicates their surgical management. Microsurgical approaches are the gold standard approaches for the resection of ventricular lesions, however, they imply considerable neurovascular risks., Case Description: A 51-year-old patient presented with acute headache, diplopia, vertigo, blurred vision, and a depressed level of consciousness. A ventricular hemorrhage was treated with a ventriculostomy and the patient was discharged without hydrocephalus. After 11 days, he developed ataxia, diplopia, and a depressed level of consciousness. The patient was diagnosed with hydrocephalus secondary to the previous third ventricle hemorrhage. An endoscopic exploration using a 30° rigid ventricular endoscope was performed; after the third ventriculostomy, an intraventricular cavernous malformation located on the floor of the third ventricle and the aqueduct of Sylvius was resected., Conclusions: Three days after the surgery, magnetic resonance imaging demonstrated a gross total resection and adequate third ventriculostomy flow. One year after the surgery, the patient was asymptomatic. Neuroendoscopy has evolved towards minimally invasiveness, and in selected cases is an equally effective surgical approach to ventricular lesions. It provides minimal cerebral cortex disruption and vascular manipulation., Competing Interests: There are no conflicts of interest.
