    Meningiomas are the most common intracranial tumors, with subtotal resections occurring in over 25% of cases, leading to postoperative remnants.

  • 2

    Established predictors of remnant progression include high histological grades, proliferative indices, peritumoral edema, and large preoperative tumor sizes.

  • 3

    The study investigates how environmental attachments, particularly to dura mater, influence the progression of meningioma remnants after subtotal resection.

  • 4

    Imaging techniques, including MRI, are utilized to assess remnant volume, intensity ratios, and attachment sites to predict remnant growth behavior.

  • 5

    Novel radiological predictors may enhance intraoperative decision-making and help identify patients at higher risk for recurrence of meningioma remnants.
