What does the markedly hyperdense material represent?
Successful glue embolization. Note the contrast and air filled cavity which was seen on angiography.
At the inferior pole of the left kidney the a fat-containing soft tissue mass measuring 8.7 x 11.2 x 11.9 is again demonstrated. There is a new curvilinear hyperdense focus within the fat-containing lesion representing sequelae of interval vascular glue embolization. The HU within the soft tissue attenuating peripheral component is approximately 66, probably representing residual hemorrhage.
The proximal ureter is displaced anteromedially resulting in hydronephrosis and proximal hydroureter.
