Free intraperitoneal air (better seen on wide windows), multiple low attenuation liver lesions with a very large lesion in segment 2/3, abnormally thickened short segment jejunal loop in the mid abdomen and several in the pelvis, pericolonic inflammation about the sigmoid colon with a probable perforated diverticulum as the cause evidenced by multiple small locules of air in that location (seen best on the wide window and coronal images), and a small amount of nonspecific pelvic fluid.
