The authors report on a patient with a malignant papillary thyroid nodule that was "cold" with Tc-99mpertechnetate and evaluated by double-phase thyroid scintigraphy with Tc-99m sestamibi (MIBI). The images were taken at 15 minutes and 2 hours postinjection. Although nodular MIBI uptake on the early scan was present, it was less intense than the extranodular thyroid tissue. The delay image showed an inverse relation of uptake, being more intense in the nodular lesion. This scintigraphic pattern could be explained by a slower washout rate of the malignant lesion. However, deleayed tracer accumulation cannot be excluded
