The liver was lobulated with a complex heterogeneous echotexture and irregular margins (Figure 1).

There was a concentric ring pattern in the transverse plane at the level of the ICCJ with wall thickening suggestive of a caecocolic intussusception (Figures 2 and 3).
Longitudinal ultrasound image of the caecocolic intussusception. On the left the ascending colon is seen. The small intestine cannot be visualised in this image

There was a concentric ring pattern in the transverse plane at the level of the ICCJ with wall thickening suggestive of a caecocolic intussusception (Figures 2 and 3).

There was a single 7 cm x 7 cm x 4 cm mass with an irregular nodular contour replacing the quadrate lobe of the liver (Figure 4).

TA-stapler (TA autosuture; Covidien). The caecum was inverted into the colon and was unable to be reduced (Figure 5).

The changes were consistent with a well-differentiated hepatocellular carcinoma with a trabecular growth pattern and cystic foci (Figure 6).
Histopathology of the caecal polyp with lymphoid follicles (arrowheads) and narrowing the caecal lumen (*). Haematoxylin and eosin stain (x 2 objective, bar = 1.3 mm)

The changes were consistent with a hyperplastic inflammatory polyp, moderate chronic typhlitis and regional caecal wall degenerative changes with early repair (Figure 7).
