ABSTRACT

The case is a female, 50s. She presented to our hospital because of her intestinal obstruction. A CT scan at her visit showed wall thickening of her ascending colon. Colonoscopy revealed type 2 advanced cancer in the ascending colon. The pathological examination was a diagnosis of adenocarcinoma. Laparoscopic right hemicolectomy was performed for cT3N1M0, cStage Ⅲb ascending colon cancer. The pathological result was pT3N1M0, Stage Ⅲb. Contrast-enhanced CT was performed 10 months after the operation. As a result, she was found to have recurrent multiple liver metastases. A laparoscopic partial hepatectomy was performed at the site of recurrence. The pathological result was adenocarcinoma. It was a diagnosis of metastasis recurrence from colorectal cancer. A CT scan 16 months after primary surgery revealed enlarged cardiodiaphragmatic lymph nodes. A PET-CT scan revealed an accumulation of SUVmax 3.0 in the same area. She was diagnosed with lymph node recurrence of colorectal cancer and underwent resection. Histopathological result was adenocarcinoma. It was diagnosed as metastasis from ascending colon cancer.
