CT and angiographic correlates: surgical image of renal mass lesions.
Twenty-three consecutive patients with surgically proved renal mass lesions were examined preoperatively by means of computerized tomography (CT) and renal angiography. Histopathology of the 23 renal masses included the following: hypernephroma (17), transitional cell carcinoma (3), oncocytoma (2), benign cyst (1). Computed tomography was correct in the preoperative diagnosis of 21 of 23 masses (91 per cent); angiographic diagnosis was correct in 18 of 23 consecutive masses (78 per cent). Correlation of the findings on CT and angiography resulted in correct diagnosis in 22 of the 23 lesions (96 per cent). Independently, CT and angiography each contribute essential information for diagnosis and preoperative planning. CT discloses anatomic detail, tissue consistency, organ system relationships, and relatively precise estimates of tumor bulk. Angiography remains a necessary complement providing a surgical image of tumor vascularity and vessel origins.
