Abstract

This study describes a unique case of single mucin-rich brain metastasis in a patient with breast cancer, mimicking the T2-fluid attenuation inversion recovery (FLAIR) mismatch sign and masquerading as an isocitrate dehydrogenase-mutant astrocytoma. This case highlights the importance of considering mucin-rich lesions in the differential diagnosis of intracranial tumors exhibiting T2-FLAIR mismatch. Clinicians must recognize the potential convergence in imaging characteristics between these metastases and gliomas to guarantee prompt and accurate patient care.

T2-fluid attenuation inversion recovery (이하 FLAIR) mismatch sign은 isocitrate dehydrogenase-mutant 성상세포종을 시사하는 영상 소견으로 알려져 있다. 이 증례 보고에서는 유방암 환자의 뇌에 생긴 점액성 뇌전이암이 T2-FLAIR mismatch sign처럼 보이는 사례를 소개한다. 특히 비조영증강 MRI에서 T2-FLAIR mismatch sign을 보이는 경우, 성상세포종 뿐만 아니라 뇌전이암을 감별진단에 염두에 두어야 한다.
