Brain metastasis frequently develops in non-small-cell lung cancer (NSCLC). Here, we report a patient who developed brain metastasis from -positive NSCLC which mimicked brain abscess. He was admitted for suspected obstructive pneumonia nine months after curative lung resection. Head magnetic resonance imaging revealed a cavitary lesion, which was compatible with brain abscess but rare in brain metastasis. However, after treatment with antibiotics, the brain lesion increased in size. Aspiration of the liquid content of the brain lesion revealed cancer cells. When a brain lesion suggestive of abscess develops in a patient with -positive NSCLC, aspiration may be necessary to differentiate metastasis from abscess.
脑转移在非小细胞肺癌（NSCLC）中经常发生。在此，我们报告一例来自阳性NSCLC的脑转移患者，其表现类似脑脓肿。他在根治性肺切除术后9个月因疑似阻塞性肺炎入院。头部磁共振成像显示一个空洞性病变，这与脑脓肿相符，但在脑转移中罕见。然而，抗生素治疗后，脑病变大小增加。对脑病变的液体内容物进行抽吸发现了癌细胞。当阳性NSCLC患者出现提示脓肿的脑病变时，可能需要进行抽吸以区分转移瘤和脓肿。
