Axial section of contrast-enhanced CT of the abdomen reveals a large heterogeneously enhancing mass with a small hyperenhancing component (asterisk). Foci of calcification are noted within the lesion (white arrow). A few hypoenhancing areas are also seen within the lesion, which might represent necrosis or scar formation. Incidentally, a ureteric calculus is seen on the right side (black arrow). Dilated ureter (u) is noted on the left side due to compression by the mass lower down. Note that the fat planes with the bowel and the retroperitoneal vessels are maintained.
