Extracolonic malignancy: Axial (a and b) and coronal (c) contrast-enhanced computed tomography images in a 73-year-old man presenting with weight loss and worsening left upper quadrant abdominal pain demonstrate a heterogeneous mass arising from the pancreatic tail which is contiguously infiltrating the splenic flexure of colon (arrow in a). There is marked distension of ascending and transverse colon and splenic flexure (asterisk) with decompressed descending colon (arrows in b and c). The large bowel obstruction resulted from contiguous infiltration of the splenic flexure from pancreatic tail cancer.
