title: Asymptomatic adult Wilm's tumor (nephroblastoma) incidentally detected by CT.
abstract: Wilms' tumor (nephroblastoma), the most common renal neoplasm in children, is rarely found in adults. A 73-year-old woman with asymptomatic adult Wilms' tumor, incidentally detected by CT, is reported. CT and MRI showed a small mass with homogeneous enhancement after the administration of contrast medium. Ultrasonography demonstrated a well-defined echogenic mass with a halo-like, peripheral hypoechoic area. Selective angiography showed no tumor vessels. Although renal cell carcinoma should be considered in the differential diagnosis, it is still difficult to distinguish from small Wilms' tumor like this case.
