title: Existence of cotton granuloma after removal of a parasagittal meningioma: clinical and radiological evaluation -a case report-.
abstract: Hemostatic agents, routinely used in neurosurgery to achieve intraoperative hemostasis may cause foreign body reaction. These may produce clinically symptomatic and radiologically apparent mass lesions. It should be kept in mind that retained cotton or rayon materials may mimic the appearance of a tumor or an abscess on MRI scan, especially at sides of previous craniotomies. Here we report a case of intracranial foreign body granuloma which occurred due to remained cottonoid after removal of a parasagittal meningioma. This entity was also documented by MR imaging technics included diffusion weighted, flair and ADC mapping.
