The remaining 2 sisters (aged 22 and 29 years) and the mother (aged 52 years) underwent a normal initial thyroid ultrasound scan, and then the yearly ultrasound surveillance was unremarkable. The father (aged 55 years) was found to have a thyroid nodule; however, he was reluctant to have FNAB until January 2018 at another institution where he was diagnosed with thyroid cancer, but we do not have any data about his follow-up there (see family pedigree in Figure 1).
