CT demonstration of liquid intratumoral fat layering in a necrotic renal cell carcinoma.
We describe a case of clear-cell adenocarcinoma of the kidney with CT evidence of fat that contradicts the rule that radiologically demonstrable fat is absent in renal carcinoma. The cyst-like appearance, egg-shell parietal calcifications, and extrarenal development of the mass suggested a preoperatively incorrect diagnosis of teratoma.
