Three phase radionuclide bone imaging procedures are used to differentiate cellulitis and osteomyelitis. Acute cellulitis is shown only as increased radioactivity in the blood flow and blood pool images; a persistent area of high activity in a delayed image is usually diagnosed as acute osteomyelitis. We present a patient with Charcot's joint secondary to diabetes mellitus whose three-phase bone imaging as well as radiographic studies revealed a consistent picture of acute osteomyelitis. In the appropriate clinical setting, Charcot's joint, along with several other etiologies (including bone tumors, leukemia, trauma, recent surgery, Paget's disease, and malunion of fracture), should be included in the differential diagnosis.
三相放射性核素骨显像检查用于鉴别蜂窝织炎和骨髓炎。急性蜂窝织炎仅在血流和血池图像上表现为放射性增强；延迟图像上持续的高活性区域通常被诊断为急性骨髓炎。我们报告一例继发于糖尿病的夏科氏关节患者，其三相骨显像以及影像学检查均显示出符合急性骨髓炎的表现。在适当的临床情况下，夏科氏关节以及其他几种病因（包括骨肿瘤、白血病、创伤、近期手术、佩吉特病和骨折不愈合）应纳入鉴别诊断。
