Increased wall thickness suggestive of tumoral infiltration is present at the rectosigmoid, causing long segment intussusception. Pericolic fat stranding and several regional enlarged lymph nodes with SAD less than 10 mm are also observed.
At least three small hypodense lesions less than 10 mm are seen in the liver, which show no frank enhancement on delayed images most consistent with cysts.
A few nonenhanced simple cortical cysts are seen in both kidneys.
A 75×60 mm cystic lesion without enhancing solid component is present at the right adnexa.
Evidence of DHS insertion is present at the proximal of the left femur causing beam hardening artifact.
Long segment rectosigmoid intussusception due to pathology proved adenocarcinoma.
Gastrointestinal malignancy, particularly colorectal cancer, is the most common cause of intussusception in adults, accounting for 65% of cases.
