A patient who had been treated for bilateral breast carcinoma subsequently developed a metastatic breast lesion in a meningioma. Although it is not uncommon for more than one tumor to occur in the same patient, metastases from one tumor into another tumor are rare (''tumor to tumor'' phenomenon). Meningiomas are the most common primary, intracranial tumors to harbor metastases, the majority of which arise from breast and lung carcinomas. Patients with a history of breast cancer and a solitary, intracranial mass with radiological features consistent of meningioma should be evaluated surgically. The lesion may be a primary cerebral malignancy, a metastatic lesion, or a meningioma with or without a metastatic lesion.
一名曾接受双侧乳腺癌治疗的患者，随后在脑膜瘤中出现了转移性乳腺病变。虽然同一患者出现不止一种肿瘤并不罕见，但肿瘤从一种肿瘤转移到另一种肿瘤的情况很少见（“肿瘤至肿瘤”现象）。脑膜瘤是最常见的发生转移的原发性颅内肿瘤，其中大多数转移瘤起源于乳腺癌和肺癌。有乳腺癌病史且有一个具有与脑膜瘤一致的放射学特征的孤立性颅内肿块的患者，应接受手术评估。该病变可能是原发性脑恶性肿瘤、转移性病变，或伴有或不伴有转移性病变的脑膜瘤。
