Tumor-to-tumor metastasis (T2Tmets) is an established entity but often overlooked and underdiagnosed. Merely 84 such cases are reported in literature till date. The authors here describe a 65-year-old man presenting with first episode of focal seizure and incidentally turned out to be a case of adenocarcinoma of lung metastatic to a meningioma. The diagnosis of T2Tmets was based solely on histopathological criteria. Recent advent of brain imaging revolutionized its diagnosis and it has moved from the realm of thologists to that of radiologists. In our case, diagnosis was also established by immunohistochemistry.
肿瘤-to-肿瘤转移（T2Tmets）是一种已被确认的实体，但常常被忽视和漏诊。迄今为止，文献中仅报道了84例此类病例。本文作者描述了一名65岁男性，首次出现局灶性癫痫发作，经偶然发现，原来是一例肺腺癌转移至脑膜瘤的病例。T2Tmets的诊断完全基于组织病理学标准。脑成像技术的最新进展彻底改变了其诊断方式，它已从病理学家的领域转移到放射科医生的领域。在我们的病例中，免疫组织化学也确立了诊断。
