Abstract

Intrabiliary metastasis from carcinoma colon is a rare entity. The incidence of intrabiliary metastasis from carcinoma rectum is 12-15% (2). About 5% of intrabiliary metastasis is attributed to hereditary colorectal cancers; Lynch syndrome being the most common. We herein present a case of a 35-year-old male patient with intrabiliary metastasis. This patient is a known case of carcinoma rectum that underwent low anterior resection and hepatic metastatectomy at the age of 20. After 15 years, he presented with a metachronous malignancy in descending colon with abdominal lymph nodal metastasis. He also had rising bilirubin levels and was found to have intrabiliary infiltrates on MRI. The final diagnosis was confirmed on spy bite cholangioscopic biopsy. This discussion highlights rare occurrences of intrabiliary metastasis from carcinoma colon.
