ABSTRACT

Objective To explore the imaging features and clinical significance of solitary costal hot spots on bone scintigraphy (BS). Methods Eighty-four patients with single costal hot spots were enrolled in the study. The sites of lesions were classified into four types junction betweenaor rib. The shapes of hot spots were classified into three forms Punctiform, clumping and strip. The above data were respectively analyzed. Results Single hot spots were mainly showed in the punctiform and strip shapes, and the distribution of punctiform spots were mainly in the sites of junction between costal cartilage and rib and frontal ribs, also mainly due to costal fractures (42/61, 68.85%). The majority of spots in strip shape were costal metastases(18/19, 94.74%). Hot spots in posterior ribs were also mainly costal metastases (24/29,82.76%). Conclusion Useful imaging features can be obtained from BS with al diagnosis of benign and malignant lesions.
