A case of septic arthritis diagnosed by combined 99m Tc-phosphate and 67Ga imaging, which preceded positive cultures of the infecting organism, is presented. A previously healthy 10-year-old girl complained of pain in her left hip with persistent fever. Initial laboratory studies showed a normal white cell count and negative blood cultures. A septic process was not confirmed. Blood flow studies and bone images with 99mTc-phosphate showed markedly increased perfusion in the left hip joint without extension to bone. Subsequent 67Ga images revealed a marked increase in radioactivity in the same region, indicating the presence of a septic process. Serial blood cultures and arthrocentesis showed Staphylococcus aureus. The patient improved on antibiotics.
本文介绍了一例通过99m锝磷酸盐和67镓联合显像诊断的化脓性关节炎病例，该病例在感染病原体培养呈阳性之前就已确诊。一名此前健康的10岁女孩抱怨左髋疼痛并持续发热。初步实验室检查显示白细胞计数正常且血培养阴性。未确诊为化脓性疾病。99m锝磷酸盐的血流研究和骨显像显示左髋关节灌注明显增加，且未蔓延至骨骼。随后的67镓显像显示同一区域放射性明显增加，表明存在化脓性病变。系列血培养和关节穿刺显示为金黄色葡萄球菌。患者使用抗生素后病情好转。
