Abstract
Background  In surgery for primary hyperparathyroidism, preoperative localization together with intraoperative parathyroid hormone assay
is important when minimal invasive operations of the parathyroid glands are intended. In cases of reoperation, correct localization
of the abnormal parathyroid glands is extremely instrumental. Computed tomography (CT)–99mTc-sestamibi (MIBI)–single photon emission computed tomography (SPECT) image fusion allows for a virtual exploration of the

Background: Autoimmune diseases have been implicated in the genesis of MALT lymphoma of various localizations. The development of thyroidal MALT lymphoma has been described as an adverse event in patients suffering from long-standing chronic autoimmune thyroiditis (CAT, Hashimoto's thyroiditis). The percentage and possible association between CAT and extrathyroidal MALT lymphoma, however, have not been assessed so far.
