Asymmetrical increased wall thickness due to tumoral infiltration is present in the distal sigmoid colon, causing colocolic intussusception. Mild surrounding fat stranding is also observed.
A few small calcified foci are seen at liver parenchyma, most consistent with healed granuloma.
The prostate gland is enlarged.
Case Discussion
The patient went to have a partial colectomy, and histopathology evaluation confirmed colon adenocarcinoma as the lead point of the intussusception.
Gastrointestinal malignancy, particularly colorectal cancer, is the most common cause of intussusception in adults, accounting for 65% of cases.
