- Abstract
OBJECTIVE: To evaluate the frequency of hypervascularization by visualizing vascular structures inside or around bone metastases from renal cell carcinoma. MATERIALS AND METHODS: Magnetic resonance imaging studies of 13 untreated patients with diagnosis of renal cell carcinoma and 15 metastatic bone lesions were retrospectively evaluated. RESULTS: Signs of hypervascularization were found in 12 of the 15 bone lesions (80%), 6 of them localized in the lumbar spine, 3 in the hip, 3 in the thoracic spine, 1 in the ulna and 1 in the tibia. CONCLUSION: The high frequency of hypervascularization of bone metastases from renal cell carcinoma found in the present study may suggest that the renal etiology is a useful parameter in the evaluation of a usual clinical presentation of a single bone lesion with unknown primary neoplasm.
