Isoechoic Thyroid Nodule With Microcalcifications, Hyperechoic or Isoechoic (1 point): Increased or similar echogenicity relative to thyroid parenchyma. Microcalcifications within a nodule are small flecks of calcification 1 mm or less in size that appear bright on an ultrasound image. Longitudinal (left) and transverse (right) planes. ncbi. Incidental thyroid nodules are being diagnosed with increasing frequency in the recent years with the use of newer and highly sensitive imaging techniques. For this reason, these nodules are carefully evaluated for other features that suggest a higher risk, such as suspicious calcifications or an irregular shape. Images from ultrasound exams performed on different patients show (a) a hypoechoic nodule, (b) a hyperechoic nodule, (c) an isoechoic nodule, (d) a heterogeneous solid nodule with both hyperechoic and hypoechoic solid portions, and (e) a mixed cystic and solid nodule in which the solid component is isoechoic to the parenchyma. For nodules with suspicious ultrasound features, such as hypoechogenicity combined with irregular margins or microcalcifications, a fine needle aspiration (FNA) biopsy is often recommended.
