摘要

异柠檬酸脱氢酶突变型胶质瘤通常比野生型胶质瘤有更好的预后。复发一般在原发肿瘤床的放射场内。远端复发不常见，通常为实质内复发。已经观察到TP53突变体向更高级别的转化。胶质瘤表现为轴外病变是非常罕见的。文献中没有报道过远端颅内轴外复发的病例。我们描述独特的影像学发现在这个情况下，并试图制定可能的诊断。术中和病理结果证实了这种不寻常的复发模式。

Unusual Extra-Axial and Extracranial Recurrence in an IDH Mutant Astrocytoma: A Case Report

Abstract Isocitrate dehydrogenase mutant gliomas generally have a better prognosis than their wild-type counterpart. Recurrences are generally within the radiation field in the primary tumoral bed. Remote recurrence is uncommon and is usually intraparenchymal. Transformation to a higher grade has been observed with TP53 mutants. Presentation of glioma as an extra-axial lesion is extremely uncommon. No such cases of remote intracranial extra-axial recurrence have been reported in the literature. We describe the unique imaging findings in this case and attempt to formulate possible diagnoses. Intraoperative and pathological findings confirmed this unusual recurrence pattern.
