April 2003. At last follow-up in 2011, there was no evidence of recurrence/relapse, as evidenced by negative PET-CT with conventional and delayed acquisition of the images 3 h after FDG injection (Figure 3), and by negative Em2+ ELISA serology (Bordier Affinity Products, Crissier, Switzerland). At that time, serology was also assessed by E. multilocularis western-blot (LD Bio, Lyon, France) in parallel on two sera: a sample frozen in 1987, and a freshly collected sample.
