Figure 2.
Images in a 51-year-old male with bilobar liver metastases of colorectal cancer (T2N1M1) show partial response after selective internal radiation therapy (SIRT). The patient then became eligible for a hepatic resection, which was subsequently successfully undertaken. (a) Pre-treatment contrast-enhanced CT image shows 42 × 36-mm target lesion in Segments II, III and IV with irregular borders (arrow). (b) Selective digital subtraction angiogram obtained during SIRT reveals the hypervascularity of the lesion (arrows). (c) Contrast-enhanced CT image after SIRT shows partial response of liver metastases (arrow). (d) CT image after liver resection shows fluid area at the resection margin (arrow). (e) Contrast-enhanced transverse CT image 3 years after liver resection. There is no evidence of recurrent disease (arrow).
