"Tumor-to-tumor" metastasis is a rare event; meningioma has been reported as the most common primary intracranial tumor to harbor cancer metastases. Several hypotheses have been previously proposed to explain this occurrence, but the exact mechanism by which these metastases develop into meningiomas is not yet understood. Magnetic resonance imaging and spectroscopy have been valuable diagnostic tools, but preoperative diagnosis of metastasis to meningioma remains highly difficult. We present a case report of a metastasis of non-small cell lung cancer into an intracranial meningioma.
“肿瘤-to-肿瘤”转移是一种罕见事件；脑膜瘤已被报道为最常见的发生癌症转移的原发性颅内肿瘤。此前已提出几种假说来解释这种现象，但这些转移瘤发展为脑膜瘤的确切机制尚不清楚。磁共振成像和光谱学一直是有价值的诊断工具，但脑膜瘤转移的术前诊断仍然非常困难。我们报告一例非小细胞肺癌转移至颅内脑膜瘤的病例。
