CRP and colonic neoplasm: On examination, there was right iliac fossa tenderness, and blood analysis was performed. Full-blood count and urea and electrolytes were all within normal range apart from a raised C-reactive protein (CRP) and mildly raised neutrophil count (Table 1). Computed tomography (CT) of the abdomen and pelvis showed circumferential thickening within the mid-transverse colon, which was concerning for colonic cancer (blue arrow, Figure 1).
