Streptococcal skeletal infections: observations in four infants.

The radiographic findings and clinical presentations of four patients with group B beta hemolytic streptococcal osteomyelitis and pyoarthritis are described. Radiographic features, though not specific, are similar in these patients and others reported in the literature. The combination of radiographic patterns and clinical presentations in children of this age group should alert clinicians and radiologists to the possibility of infection with this organism.
