Cervical osteomyelitis due to i.v. heroin use: radiologic findings in 14 patients.

We reviewed the radiographs of 14 patients who had cervical osteomyelitis and were IV heroin users. Eleven were men and three were women. Their age range was 33-48 years (mean, 39 years). Eleven regularly used the jugular vein access, and three alternated between the jugular and femoral veins. Initial radiographs of the cervical spine in 13 patients showed destruction of two or more vertebral bodies and the adjacent intervertebral disk, as well as a prevertebral soft-tissue mass. In one patient, findings on initial radiographs were normal, but marked destruction at two contiguous intervertebral levels and a large prevertebral abscess were identified 2 weeks later. All the patients had positive results on cultures of joint aspirates or bone biopsy materials (10 patients) or blood (four patients). Ten grew Staphylococcus aureus; two, Staphylococcus epidermidis; one, Streptococcus viridans; and one, Pseudomonas aeruginosa. CT in nine patients showed inflammatory reaction adjacent to the carotid sheath resulting from the repeated jugular injections and delineated the extent of prevertebral abscess and bone destruction. Scintigrams were of minimal value in establishing the diagnosis. Advanced vertebral body destruction, disk space infection, prevertebral abscess, and anterior cervical inflammatory reaction appear to be typical findings on radiographs in heroin abusers with cervical osteomyelitis.
