Findings was changed:

There is a well-defined septated cystic lesion measuring 5.0 x 6.7 cm at the upper pole of the right kidney. A few tiny, faint calcifications are seen within it.  Post The post-contrast study shows enhancement in the irregular septations as well as in the walls of the cyst. No No soft tissue or hemorrhagichaemorrhagic component is seen.

A few proximal jejunal loops show diffuse mural thickening and intense enhancement of the valvulae conniventes.

Impression: Multiseptatedmultiseptated cystic lesion at the upper pole of the right kidney, which is likely a Bosniak type 3 cyst. Diffusely thickened proximal jejunal loops with enhancingenhanced valvulae conniventes; inflammatory/infective enteritis
