Core Tip
Core tip: The computerized tomography (CT) imaging appearance of renal cell carcinoma recurrence mimics the appearance of the primary tumor. Just as a majority of renal cell carcinomas are hypervascular, recurrences tend to be hypervascular and are best seen on arterial phase. This paper demonstrates this tendency by giving case examples which review both common and uncommon sites of recurrence. Knowledge of their appearances on CT will help the radiologist in lesion detection and diagnosis, limiting delays in treatment and avoiding unnecessary biopsies.
