Abstract
Introduction: Musculoskeletal soft tissue can be defined as the periskeletal non-epithelial connective tissue of the body exclusive of reticuloendothelial system. Various benign and malignant lesions are seen to arise from musculoskeletal soft tissue. Ultrasonography is usually performed as a first step in the assessment of musculoskeletal soft tissue masses. Using B-mode, Doppler ultrasonograghy and Spectral wave analysis we can differentiate benign from malignant musculoskeletal soft tissue masses. Aim: to study the role of b-mode, doppler ultrasonograghy and spectral wave analysis in differentiating benign from malignant musculoskeletal soft tissue masses. Methods: Fifty patients with musculoskeletal soft tissue masses (28 benign, 22 malignant) prospectively evaluated using B-mode, doppler ultrasonograghy and spectral wave analysis to assess their role in differentiating benign from malignant lesions. Later the findings obtained were confirmed by histopathological study of masses. Results and Discussion: B- Mode ultrasonography showed 47.5% sensitivity, 80.8% specificity, 78.3% positive predictive value, 62.3% negative predictive value and 62% accuracy in differentiating benign from malignant lesions. Color doppler and spectral wave analysis showed 76.4% sensitivity, 76.4% specificity, 76.1% positive predictive value, 83.7% negative predictive value and 76% accuracy in differentiating benign from malignant lesions. Our study showed that conventional sonography reliable for diagnosing malignancy, it has good accuracy, good specificity and good positive predictive value, however has equivocal sensitivity and negative predictive value. Color Doppler and spectral wave analysis are reliable tools and show good accuracy, sensitivity, specificity, positive predictive value and negative predictive value in diagnosing and differentiating benign from malignant soft tissue masses. Conclusion: Color and spectral Doppler assessment of musculoskeletal soft tissue masses might represent an important supplement to B-mode sonography and should always be performed when evaluating the same by ultrasonography.
