[Parasigmoid abscess revealed by anaerobic osteomyelitis].

We report the case of a 66 year-old-patient, who profited by a laminectomy T4 to T7 for spinal cord compression due to an osteomyelitis. Bacteriological samples showed positives gram cocci and Bacteroides fragilis by the culture. The systematic research of a primitive source permitted to find a parasigmoidis abscess, which was treated by a sigmoidectomy with a colorectal anastomosis.
