[A Case of Brain, Lung, and Adrenal Metastasis from Colorectal Cancer Controlled by Loco-Regional Surgery].

: A 64-year-old man presented with the chief complaint of weakness in the left half of his body. He fell down on the road while riding a bicycle and was transported to the emergency room. A contrast-enhanced brain MRI revealed a 28mm ringshaped mass in the right frontal lobe. A craniotomy was performed 14 days later. The histopathological diagnosis showed the tumor as a well-differentiated tubular adenocarcinoma. Postoperative examination revealed a rectal cancer and a left lung mass. A low-anterior resection was performed 1 month after the craniotomy, and a partial lung resection was performed 2 months after the rectal excision. Metachronous solitary metastasis of the left adrenal gland was noticed 10 months after the removal of the lung metastasis and we subsequently performed a left adrenalectomy. The patient is not undergoing any active treatment 13 months after the adrenalectomy, but has no signs of recurrence. The loco-regional surgery was enabled for local control of multi-relapsed lesions from rectal cancer.
