Figure 2. Imaging of the three cases. (A) Initial localization of I-PA was achieved by ultrasound (US) and 18F fluorocholine PET/CT. Pre- and post-operative contrast-enhanced US demonstrated the complete treatment of the lesion. During follow-up, I-PA showed strong hypoechogenicity. (B) Initial localization of I-PA was achieved by US and scintiscan. Pre- and post-operative contrast-enhanced US demonstrated the complete treatment of the lesion. During follow-up, I-PA showed strong hypoechogenicity. (C) I-PA was initially suspected at thyroid US. FNA-PTH was then performed and the results did not indicate for further imaging procedure. One month later, US and US and contrast-enhanced US demonstrated good the RF efficacy.
