Concurrent bacteremia and colorectal adenocarcinoma with metastasis to the brain - A Case Report.

There is a known relationship between bacteremia and colorectal malignancies. is a gram-positive, anaerobic, spore-forming bacterium that can survive the acidic colorectal tumor microenvironment, where it is thought to enter the blood by tumor-mediated epithelial tissue damage. While in circulation, can release exotoxins which may lead to life-threatening sepsis. The patient in this case presented with a mild fever, abdominal pain, and left hand weakness. Imaging of the head and abdomen revealed a right frontal lucency and wall thickening of the ascending colon. Two colonic adenocarcinomas were found and removed via an exploratory laparotomy and right hemicolectomy. The blood culture was positive for . Brain MRI confirmed a right frontal mass concerning for metastasis. Here, we discuss the relationship between colonic cancers and bacteremia.
