Click Renal Cell Carcinoma presenting as small bowel obstruction secondary to a metastatic ileal intussusception.
CT of the abdomen and pelvis, Phase: Plain, Plane: Axial, Slice width: 5 mm
Findings:
1. A large, irregular, mass measuring 10.1x7.8x7.5 cm (anteroposterior x mediolateral x superoinferior) noted arising from the lower pole of the left kidney. The mass is of soft tissue density with irregular hypodense areas centrally on the plain scan.
2. The small bowel loops are dilated. A soft tissue density endoluminal polypoidal mass lesion measuring 2.3x2.0x1.5 cm (anteroposterior x mediolateral x superoinferior) is seen at the lead point of an intussuecpetion in one of the distal ileal loops in the right lower quadrant of the abdomen.
3. Soft tissue density nodular lesions are seen in the posterobasal segment of the right lung and in the right gluteal muscles s/o metastases from the renal cell carcinoma.

CT of the abdomen and pelvis, Phase: Arterial, Plane: Axial, Slice width: 1 mm
Findings:
1. A large, irregular, avidly enhancing mass measuring 10.1x7.8x7.5 cm (anteroposterior x mediolateral x superoinferior) is noted arising from the lower pole of the left kidney which shows neovascularity on the arterial phase. The mass extended into the perinephric fat. Anteriorly, the gerota`s fascia was intact.
2. The small bowel loops are dilated. A heterogeneously and avidly enhancing endoluminal polypoidal mass lesion measuring 2.3x2.0x1.5 cm (anteroposterior x mediolateral x superoinferior) is seen at the lead point of an intussuecpetion in one of the distal ileal loops in the right lower quadrant of the abdomen which had few small non-enhancing necrotic areas within showing an enhancement pattern similar to that of the renal mass indicating metastastic intussusception.
3. Heterogeneously and avidly enhancing soft tissue density nodular lesions are seen in the posterobasal segment of the right lung and in the right gluteal muscles s/o metastases from the renal cell carcinoma.
