Bacteroides bacteremia - colorectal cancer

Case contributed by Dr Henry Knipe

Presentation

Bacteroides bacteraemia. Acute renal failure.

Patient Data

Age: 85 years
Gender: Male

Intravenous contrast withheld due to acute renal failure. 

Large pelvic mass lying between the bladder and rectum. Multiple hepatic masses. Left iliac chain and para-aortic lymphadenopathy. Small volume ascites and omental fat stranding. 

Left hydronephrosis. Left adrenal mass.  

Case Discussion

The imaging findings are suspicious for metastatic colorectal cancer, especially in the setting of a Bacteroides bacteremia. Bacteroides bacteremia has a high mortality rate (~25%) with malignancy, in particular, colorectal cancer, being a major association and is often the primary infection site. The patient died before a histological diagnosis was made.
