Pediatric osteomyelitis commonly occurs in the long bones and has rarely been reported in small bones such as the vertebrae and ribs. Rib osteomyelitis occurs in approximately 1% or less of all cases of hematogenous osteomyelitis, and is usually caused by Staphylococcus aureus. We present a case of acute osteomyelitis in the rib of an otherwise healthy and afebrile 1-year-old infant that appeared as a lytic bone lesion on imaging studies and was mistaken for a tumor. Biopsy was needed to rule out malignancy and establish the diagnosis of osteomyelitis caused by group A Streptococcus. This is one of the few reported cases of pediatric rib osteomyelitis caused by this organism.
小儿骨髓炎常见于长骨，而在椎骨和肋骨等小骨中很少见报道。肋骨骨髓炎在所有血源性骨髓炎病例中发生率约为1%或更低，通常由金黄色葡萄球菌引起。我们报告一例1岁健康且无发热的婴儿肋骨急性骨髓炎病例，该病例在影像学检查中表现为溶骨性骨病变，曾被误诊为肿瘤。需要通过活检排除恶性肿瘤，并确诊为由A组链球菌引起的骨髓炎。这是少数几例由该病原体引起的小儿肋骨骨髓炎报道病例之一。
