左边(图右侧)为肺癌的脑转移。转移大多数出现在大脑中动脉分布区的灰质和白质的分界处,如图所示。
At the left is seen a metastasis from a lung carcinoma. Metastases most often appear at the border of the grey and white matter in the distribution of the middle cerebral artery, as in this case, because that is where the blood flow (vascular distribution) is most likely to take metastases.
