Abstract
MALT lymphoma of the thyroid is uncommon, comprising
approximately 4% of all extranodal MALT lymphomas and
commonly arises in a setting of Hashimoto thyroiditis. A 57-yearold
female with Hashimoto thyroiditis was studied with Tc-99m
pertechnetate thyroid scan to evaluate thyroid function. Radionuclide
thyroid scan with Tc-99m pertechnetate revealed a medium
sized, cold nodule in the enlarged left thyroid lobe. Preoperative
contrast enhanced CT of the neck revealed a large focal area with
less enhancing in the same area. The histologic examination was
reported to be a lymphoproliferative lesion, extranodal marginal
zone B-cell lymphoma (MALT lymphoma) with Hashimoto thyroiditis.
A cold nodule of the thyroid gland is a nonspecific finding, and
the possibility of MALT lymphoma should be considered.
Key Words: MALT lymphoma, Hashimoto thyroiditis, cold
nodule, Tc-99m O4
