Recurrence in colorectal cancer after surgical resection is common. The most common sites of recurrence are local recurrence, the liver, the lung, and the peritoneum. We present the rare case of a 57-year-old woman with rectal cancer who had undergone a radical proctectomy about 5 years earlier. Solitary recurrence in a right pulmonary hilar lymph node was detected on her follow-up F-18 FDG PET/CT. A pathology report confirmed a metastatic adenocarcinoma of colorectal origin.

大腸直腸癌術後的復發是很常見的。最常見復發的部位是局部復發、肝、肺和腹膜。本文報告一位57歲的女性，5年前因為直腸癌而進行直腸切除。追蹤正子掃描發現右肺門有唯一的淋巴結復發，病理報告證實是轉移性直腸癌。
