The content of uridine-diphosphate (UDP)-saccharides, such as UDP-glucose (UDPG) and UDP-N-acetylglucosamine (UDPAG) was examined in the meningiomas obtained at surgery. Typical, atypical, and anaplastic meningiomas were used. Biochemical data were compared with histological findings. The total level of UDP-saccharides (UDPG + UDPAG) in the meningiomas was demonstrated not to depend on the grade of anaplasia. A positive correlation was found between the UDPG/UDPAG ratio was from 1.73 in typical (benign) neoplasms to 6 or even higher in meningiomas with severe sings of malignancy (anaplastic meningiomas). The UDPG/UDPAG ratio seems to reflect the nature and rate of tumor growth.

Transcranial neurosurgery assisted by endoscopy and intraoperative ultrasound (IOUS) has become an effective approach for real-time visualization and guidance during tumor resection. This study explores the application of these techniques in falcine meningioma (FM) resection, assessing their feasibility and safety. Eleven FM patients underwent transcranial endoscopic resection with IOUS assistance.

Article Synopsis
- Pediatric intracranial tumors at the skull base are rare, challenging to treat due to complex anatomy, and lack substantial clinical evidence, prompting a study on surgical approaches and outcomes.
- The study involved 12 children under 18 who underwent skull base surgery from 2017 to 2023, analyzing demographics, tumor details, surgical methods, and survival rates.
- Results indicated a predominance of female patients, varying tumor locations and types, with 58.3% achieving gross or near-total resection; however, 33.3% of patients died from tumor progression within an average of 15 months.

Article Synopsis
- * A case study is presented about a 51-year-old woman with a Grade 2 meningioma that ultimately transformed into a Grade 1 meningioma after surgical intervention and follow-up.
- * The transformation from Grade 2 to Grade 1 meningioma is rarely documented and not well-understood, leading to insights on its natural progression and the importance of radiological and histopathological assessments in treatment planning.

Article Synopsis
- Grade 3 meningiomas are rare and linked to high morbidity and mortality, but the effects of surgical resection and radiation therapy on patient outcomes are still debated.
- A study was conducted on 65 patients with de novo anaplastic meningiomas, revealing a median progression-free survival of 23 months and an overall survival of 2 years, with certain treatments showing significant impact.
- The combination of gross-total resection and adjuvant radiotherapy improved progression-free survival, while tumor grade and age at diagnosis also affected outcomes.
