Intraparenchymal hemorrhage from dural metastasis of breast cancer is rare. A 54-year-old woman without a significant medical history showed altered consciousness and left hemiparesis. Radiological examination revealed an extra-axial mass in the right middle fossa with intraparenchymal hemorrhage and another mass invading the skull in the right parietal region. The pre-operative diagnosis was a sphenoid ridge meningioma presenting with intraparenchymal hemorrhage and another meningioma in the convexity. The tumors and hematoma were removed. Pathological findings of the tumors were compatible with adenocarcinoma. Systemic examination revealed breast cancer with metastasis to the spine. Although the radiological findings were similar to those of meningioma, a differential diagnosis of metastatic brain tumor with intraparenchymal hemorrhage should be taken into consideration.
乳腺癌硬脑膜转移引起的脑实质内出血较为罕见。一名54岁无重大病史的女性出现意识改变和左侧偏瘫。影像学检查显示右侧中颅窝有一个轴外肿块伴脑实质内出血，右侧顶叶区域有另一个肿块侵犯颅骨。术前诊断为蝶骨嵴脑膜瘤伴脑实质内出血以及凸面另一个脑膜瘤。切除了肿瘤和血肿。肿瘤的病理结果符合腺癌。全身检查发现乳腺癌伴脊柱转移。尽管影像学表现与脑膜瘤相似，但应考虑脑实质内出血性转移性脑肿瘤的鉴别诊断。
