There is an irregular mass in the distal sigmoid colon, with a tract extending from this mass into nearby rectosigmoid junction. Regionally there is an irregular, heterogeneous and enlarged lymph node. Colonic diverticulosis is present. No distant metastases are shown.
Conclusion:
Distal sigmoid carcinoma, fistulating into nearby rectosigmoid junction.

Tumor perforation can result in localized or peritoneal gas, as well as fistulation into nearby organs.
