Metastasis from extracranial tumor into an intracranial primary tumor is an uncommon event. A predominant tendency of meningioma to be the host tumor for breast carcinoma has been found. In the current report, three cases of breast carcinoma metastatic to intracranial meningiomas are described. In our cases, metastasis in meningioma was the first clinical manifestation of the occult primitive breast carcinoma. We review widely the literature concerning such rare occurrences and discuss all the postulated pathogenetic mechanisms. There are few cases reported in the literature on resonance magnetic imaging of metastatic carcinoma in meningioma. Two of our patients have been studied by MRI, but we do not find predictive radiological finding of this particular association.
颅外肿瘤转移至颅内原发性肿瘤是一种罕见事件。已发现脑膜瘤作为乳腺癌宿主肿瘤的主要倾向。在本报告中，描述了3例乳腺癌转移至颅内脑膜瘤的病例。在我们的病例中，脑膜瘤转移是隐匿性原发性乳腺癌的首发临床表现。我们广泛回顾了有关此类罕见情况的文献，并讨论了所有假定的发病机制。关于脑膜瘤中转移性癌的磁共振成像，文献报道的病例很少。我们的2例患者接受了MRI检查，但未发现这种特殊关联的预测性影像学表现。
