Abstract
Metastasis to the liver from thyroid cancer is a rare event with a reported frequency of 0.5%. Metastatic liver involvement from differentiated thyroid cancer (DTC) is nearly always multiple or diffuse and usually found along with other distant metastases (lung, bone and brain). The authors describe a patient with a solitary liver metastasis from Hürthle cell thyroid cancer, which appeared during long-term follow-up. The lesion was diagnosed by progressive increase of thyroglobulin in the serum and imaged with I-131 whole body scan, ultrasonography, magnetic resonance imaging (MRI) and F-18 fluoro-deoxyglucose positron emission tomography (FDG-PET) scan. For patients with a Tg level above some arbitrary limit, the administration of a large dose (3.7–5.5 GBq; 100–150 mCi) of I-131, in order to obtain a highly sensitive Tx whole body scan (WBS), remains the best diagnostic strategy. However, on very rare occasions, physiological enteric radioactivity can hide possible abdominal lesions and further indepth studies, such as FDG-PET scans, are sometimes necessary.
