title: MR imaging of recurrent colorectal carcinoma versus fibrosis.
abstract: Locally recurrent cancer can be difficult to distinguish from postoperative and radiation fibrosis on most imaging modalities. We report a case in which magnetic resonance imaging suggested the presence of both fibrosis and recurrent tumor in a patient following abdominoperineal resection for colorectal carcinoma, and demonstrate its role for precise needle placement when percutaneous biopsy is recommended.
