From: Localized subacute thyroiditis presenting as a painful hot nodule
Initial thyroid ultrasound scanning and 99 m-Technetium scintiscan. A. Thyroid ultrasonography revealed a dyshomogeneous and hypoechoic nodule (15 × 0.8 mm) with an irregular and poorly defined border in the left thyroid lobe (indicated by a white arrow). B. Thyroid scintigraphy with 99 m-Tc showed a focal accumulation of radiotracer uptake in the lower lobe of the left thyroid, which represents the palpable tender nodule (indicated by a black arrow).
