A cold nodule is a thyroid nodule that does not produce thyroid hormone. On a radioactive iodine uptake test a cold nodule takes up less radioactive material than the surrounding thyroid tissue. A cold nodule may be malignant or benign. On scintigraphy cold nodules do not show but are easily shown on ultrasound. Figure 1 illustrates the basic anatomy of the thyroid gland. The case shown in Figure 4 shows a cold nodule quite emphasized representation of the thyroid. The investigation was carried out due to a goiter rating of 3. Striking was the discrepancy between the magnification sonographically depicted the thyroid lobe and the findings in the scintigraphy; the lower part of the right lobe and the lateral part of the left missing in the bone scan, although demonstrably thyroid tissue is

| - العقيدة الباردة (بالإنجليزية: Cold nodule) هي عقيدة درقية لا تُنتِج هرمونات درقية. في اختبار قبط اليود المشع، تمتص العقيدات الباردة مادة مشعة أقل من أنسجة الغدة الدرقية المحيطة. قد تكون العقيدة الباردة خبيثة أو حميدة. لا تظهر العقيدات الباردة في التصوير الومضاني ولكن يمكن رؤيتها بسهولة باستخدام الموجات فوق الصوتية. 5-10% من العقد الباردة تكون خبيثة.

- Ein „Kalter Knoten“ ist ein szintigrafischer Befund (hypofunktioneller Bezirk/Knoten) an der Schilddrüse. Die Bezeichnung „kalter Knoten“ bezieht sich auf die reduzierte oder nicht vorhandene Fähigkeit des Gebiets, radioaktives („heißes“) Jod oder Technetium aufzunehmen. Kalte Knoten produzieren wenig oder keine Schilddrüsenhormone Trijodthyronin (T3) und Thyroxin (T4).(Hauptartikel: Schilddrüsenszintigraphie)

Striking was the discrepancy between the magnification sonographically depicted the thyroid lobe and the findings in the scintigraphy; the lower part of the right lobe and the lateral part of the left missing in the bone scan, although demonstrably thyroid tissue is present there sonographically. This imperfective representation for thyroid tissue is the characteristic of "cold node". "Cold nodule" in older women usually benign and 15-20% Malignant. And in Men or child cancer until proven otherwise.
