TN can be triggered by many factors, with rare cases (< 0.05% of the general population) associated with vertebrobasilar dolichoectasia (VBD). Our study analyzes a 74-year-old male patient with 10 years of constant unbearable left-sided facial pain, unresponsive to medications and multiple glycerol rhizotomies, performed in other centers which prompted the patient to seek care at our clinic. The confirmation of left-sided VBD by magnetic resonance imaging, computed tomography angiography, and the patient's overall satisfactory health status favored open surgery with microvascular decompression (MVD). We performed a retrosigmoid suboccipital craniotomy to reach the cerebellopontine angle, ensuring that it is the dolichoectatic basilar artery applying compression to the trigeminal nerve. We inserted a shredded Teflon implant into the trigeminal cistern following its opening. Care was exercised to ensure that there were no remaining factors causing compression. Postoperatively, pain relief was achieved, sustained at an 8-month follow-up. Treating TN arising from VBD can be difficult. The patient's overall health status and assessment play a key role in determining the appropriate course of treatment. Opting for MVD is the optimal and most effective choice, regardless of age, according to the recent literature. In cases where surgery is not feasible, the treatment options will involve medications and less invasive therapeutic approaches such as peripheral rhizotomies or stereotactic radiosurgery.

{"title":"The Effect of Preoperative Cabergoline on Prolactinoma Fibrosis: A Case Series.","authors":"Isabella L Pecorari, Eros Qama, Nadeem Akbar, Patrick Colley, Christina H Fang, Vijay Agarwal","doi":"10.1055/s-0044-1786740","DOIUrl":"10.1055/s-0044-1786740","url":null,"abstract":"<p><p><b>Introduction</b>  Prolactinomas are a common intracranial neoplasm and constitute most pituitary tumors. Although patients can present with variable hormone dysregulation and symptom severity, the use of dopamine agonists remains a first-line treatment. While bromocriptine has been found to increase tumor fibrosis, the effect of cabergoline on collagen deposition has been disputed. The aim of this article is to understand the influence of cabergoline on tumor fibrosis prior to resection. <b>Case Presentations</b>  Four male patients who underwent prolactinoma resection were included in this report. The average age was 39.8 years (range: 26-52 years). Pre-treatment prolactin levels ranged from 957.8 to 16,487.4 ng/mL. Three patients received cabergoline for at least 1 month prior to surgery (treatment range: 1-6 months). One patient had surgery without prior cabergoline use. Pathology reports confirmed each tumor to be of lactotroph origin. For each sample, Masson's trichrome staining was performed and the percentage of sample fibrosis was quantified using an artificial intelligence imaging software. Among those who received preoperative cabergoline, the extent of tumor fibrosis was in the range of 50 to 70%. In contrast, specimen fibrosis was approximately 15% without cabergoline use. <b>Conclusion</b>  This report demonstrates that a short duration of preoperative cabergoline can cause significant prolactinoma fibrosis. Understanding the effect of cabergoline on tumor consistency prior to surgery is essential as increased fibrosis can lead to more difficult tumor removal, reduce the extent of resection, and increase surgical complications. Considering these effects, further studies regarding the use of surgery prior to cabergoline for prolactinoma management are warranted.</p>","PeriodicalId":44256,"journal":{"name":"Journal of Neurological Surgery Reports","volume":"85 2","pages":"e66-e73"},"PeriodicalIF":0.5,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11095984/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140945231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
