Abstract
Ultrasonography is usually the first investigation to distinguish between solid and cystic renal masses and to further characterize these lesions. The role of needle aspiration to confirm the diagnosis is limited. Color flow Doppler sonography is a reliable means of differentiating between benign and malignant renal masses. Power Doppler sonography is a better measure of tissue perfusion. Twenty-three patients with renal masses were studied with power and color Doppler sonography and imaging diagnoses were correlated with final histopathological reports (benign or malignant). All the twenty-three cases were subjected to histopathological examination. It was found that the radiological diagnosis was correct in 22 (95%) of 23 cases. One case with Grade III vascularity was diagnosed as malignant on color Doppler sonography but as inflammatory mass on histopathology.
