Development of renal scars on CT after abdominal trauma: does grade of injury matter?
Grades I and II renal injuries heal completely, whereas higher grades of renal trauma result in permanent parenchymal scarring. Hence, incidentally discovered renal scars in patients with a history of minor renal trauma should be attributed tentatively to other causes that may or may not require additional investigation.
In addition to known risk factors, age independently predicts the risk of SLN metastasis in breast cancer. Angiolymphatic invasion seems to be a more powerful predictor of SLN metastasis in older patients.
