Brain metastasis of colorectal cancer is infrequent, and isolated brain metastases are more infrequent. Thus, when neurological symptoms, such as paralysis or disturbance of consciousness appear, there is a high probability that the cancer has spread to other organs.
Here, we present a 64-year-old man with a progressive headache, decreased motivation, and aphasia who was diagnosed with a brain tumor in the left frontal region. He underwent a craniotomy, and the brain tumor was diagnosed as adenocarcinoma. We performed a colonoscopy and diagnosed rectal cancer without other distant metastases. After whole-brain radiotherapy (WBRT), low anterior resection for primary rectal tumor was performed using a robotic system. The patient was discharged in good condition and received postoperative adjuvant therapy for rectal cancer. He showed no signs of recurrence after 1 year of follow-up.
We described a rare case of rectal cancer that was diagnosed after resection of isolated brain metastasis. A good prognosis was achieved with surgery and WBRT.
结直肠癌脑转移并不常见，孤立性脑转移更为罕见。因此，当出现诸如瘫痪或意识障碍等神经症状时，癌症扩散至其他器官的可能性很高。
在此，我们报告一名64岁男性，患有进行性头痛、动力减退和失语症，被诊断为左额叶脑肿瘤。他接受了开颅手术，脑肿瘤被诊断为腺癌。我们进行了结肠镜检查，诊断为直肠癌且无其他远处转移。在全脑放疗（WBRT）后，使用机器人系统对原发性直肠肿瘤进行了低位前切除术。患者出院时情况良好，并接受了直肠癌术后辅助治疗。随访1年后未出现复发迹象。
我们描述了一例罕见的直肠癌病例，该病例在孤立性脑转移切除术后被诊断出来。通过手术和WBRT取得了良好的预后。
