“…Jiang et al [ 11 ] also reported the use of occipitocervical fusion in 6 patients (1.7%) after cervical laminectomy and facetectomy. As regards intraoperative neuromonitoring adjuncts, monitoring on the lower cranial nerves (IX-XII) was used in 22 patients (6.2%) [ 35 , 36 , 37 , 38 , 39 , 40 , 41 ], monitoring of the somatosensory evoked potentials in 17 patients (4.8%) [ 11 , 21 , 42 , 43 , 44 ], monitoring of the motor evoked potential in 16 patients (4.5%) [ 11 , 21 , 42 , 45 , 46 ], and monitoring the brainstem evoked potential in 1 patient (0.3%) [ 38 ]. Similarly, microdoppler assistance was used only by Oichi et al [ 26 ] to detect the relationship of the tumor and the surgical resection to the proximal arterial and venous structures in 1 patient (0.3%).…”

Background: Craniovertebral junction (CVJ) schwannomas are rare, with surgery and stereotactic radiosurgery (SRS) being effective yet challenging options. We systematically reviewed the literature on CVJ schwannomas. Methods: PubMed, Scopus, Web-of-Science, and Cochrane were searched following the PRISMA statement to include studies reporting CVJ schwannomas. Clinical features, management, and outcomes were analyzed. Results: We collected 353 patients from 101 included articles. Presenting symptoms were mostly neck pain (30.3%) and headache (26.3%), with most cranial neuropathies involving the XII (31.2%) and X (24.4%) nerves. Most tumors originated from C2 (30.9%) and XII (29.4%) nerves, being extracranial (45.1%) and intradural-extradural (44.2%). Erosion of C1–C2 vertebrae (37.1%), the hypoglossal canal (28.3%), and/or jugular foramen (20.1%) were noted. All tumors were operated, preferably with the retrosigmoid approach (36.5%), with the far-lateral approach (29.7%) or with the posterior approach and cervical laminectomy (26.9%), far-lateral approaches (14.2%), or suboccipital craniotomy with concurrent cervical laminectomy (14.2%). Complete tumor resection was obtained most frequently (61.5%). Adjuvant post-surgery stereotactic radiosurgery was delivered in 5.9% patients. Median follow-up was 27 months (range, 12–252). Symptom improvement was noted in 88.1% of cases, and cranial neuropathies showed improvement in 10.2%. Post-surgical complications occurred in 83 patients (23.5%), mostly dysphagia (7.4%), new cranial neuropathies (6.2%), and cerebrospinal fluid leak (5.9%). A total of 16 patients (4.5%) had tumor recurrence and 7 died (2%), with median overall survival of 2.7 months (range, 0.1–252). Conclusions: Microsurgical resection is safe and effective for CVJ schwannomas. Data on SRS efficacy and indications are still lacking, and its role deserves further evaluation.

“…Meningioma is the most common primary intracranial neoplasm, with a prevalence rate of 14.3% to 19% (Ichwan et al, 2023). About 70% to 80% of all meningiomas are benign tumours (WHO grade 1), while 20% to 30% are atypical or borderline (WHO grade 2), and 1% to 2% are malignant WHO grade 3 tumours (Ji et al, 2015).…”

The incidence of meningiomas in the United States of America and the world has reached 1.28/100,000 and 70.7/10,000, respectively (Ichwan et al, 2023). According to the Central Brain Tumor Registry in the United States (CTBRUS), meningioma is America's most frequent primary brain tumour (Ichwan et al, 2023).…”

Meningioma is the primary central nervous system tumour with the highest recorded prevalence. Research on meningiomas has shown an association with hormone receptor expression, but the underlying pathophysiologic mechanisms remain unclear. This systematic review presents the available information on the role of progesterone and estrogen in meningioma’s pathogenesis, prognosis, and treatment. The study used the Preferred Reporting Items for Systemic Review and MetaAnalysis (PRISMA) 2020 guidelines. The authors searched and downloaded relevant published articles from the following databases; PubMed, PubMed Central (PMC), MEDLINE, the Cochrane Library, and Google Scholar. The downloaded articles were screened using set eligibility criteria and appropriate quality appraisal tools and subsequently relevant data was extracted using standardized questionnaires. Based on the papers reviewed, progesterone receptor expression in meningioma is associated with significantly more favourable prognostic factors and treatment outcomes while a negative correlation exists between overall survival and the presence of estrogen receptors. In conclusion, analysing hormone receptor expression in meningioma appears necessary for targeted hormonal and endocrine therapy. A suitable reference population must also be defined in future extensive prospective multi-centre and multi-national clinical studies

“…2 Accordingly, they may lead to brainstem compression and progressive cranial nerves dysfunction. [2][3][4] Given the relatively frequent recurrences after partial resections, the goal of surgery is gross total resection with preservation of lower cranial nerves function. 2,5,6 Adequate exposure is the key to total surgical removal with preservation of the vital neurovascular structures.…”
