The clinical information and imaging data from 27 patients with hematogenous pyogenic vertebral osteomyelitis were reviewed.All patients had roentgenographic and magnetic resonance imaging examinations.Seventeen patients had computed tomograms;17 had technetium Tc 99m medronate bone scans;and seven had gallium citrate Ga 67 scans.Magnetic resonance imaging,when used as a part of the initial radiologic evaluation,detected abnormalities consistent with osteomyelitis in all 27 patients.Magnetic resonance imaging also demonstrated paravertebral and/or epidural extension of infection in 14 patients,including seven patients who had neurologic signs of lower-extremity weakness.Roentgenograms,computed tomograms,techntium bone scans,and gallium scans had findings suggestive of the diagnosis in 48%,65%,71%,and 86%of the patients,respectively.We recommend magnetic resonance imaging as an important and perhaps critical imaging modality for detection of pyogenic vertebral osteomyelitis. |
