Benign hepatic neoplasms: an update on cross-sectional imaging spectrum.

abstract：:Two cases of thyroid-related papillary adenocarcinoma are presented. Both patients had clinically benign neck masses that were clearly separated from the thyroid gland. In both cases the thyroid gland was normal to clinical evaluation, CT, and 99mTc scanning. One patient had an occult thyroid carcinoma with a solitary...
