To our knowledge, this is a unique report of intraoperative magnetic resonance imaging (iMRI) of an intracranial cottonoid. The current literature describes images of cottonoids as a post-operative finding in the setting of an unintentionally retained foreign body; however, the iMRI images we present are important as the use of iMRI in the resection of complex tumors and epilepsy foci increases. This series of images was obtained during a craniotomy for tumor resection of a patient with dysembryoplastic neuroepithelial tumor. To determine both the degree of tumor resection and the amount of residual tumor, cottonoids were left in our patient's resection cavity and underwent iMRI. The ability to distinguish cottonoids in these images is important for intraoperative localization of resection margins and to prevent the retention of cottonoids.
据我们所知，这是一篇关于颅内棉片的术中磁共振成像（iMRI）的独特报告。目前的文献将棉片的图像描述为无意中残留异物情况下的术后发现；然而，随着iMRI在复杂肿瘤和癫痫病灶切除中的应用增加，我们展示的iMRI图像具有重要意义。这一系列图像是在为一名患有胚胎发育不良性神经上皮肿瘤的患者进行肿瘤切除开颅手术期间获得的。为了确定肿瘤切除的程度和残留肿瘤的数量，在我们患者的切除腔内留置了棉片并进行了iMRI检查。在这些图像中区分棉片的能力对于术中确定切除边缘的位置以及防止棉片残留非常重要。
