45-year-old female presents for evaluation of a known thyroid nodule. RIGHT LOBE MEASUREMENTS: 5.1 x 2.2 x 2.6 cm.LEFT LOBE MEASUREMENTS: 4.9 x 1.7 x 1.7 cm.ISTHMUS MEASUREMENTS: 0.5 cm.RIGHT LOBE: There is a well-defined dominant hypoechoic nodule measuring approximately 2.4 x 2.1 x 2.1 cm with some spongiform components in the right mid pole of the thyroid. Otherwise, the parenchyma on the right appears mildly heterogeneous. LEFT LOBE : Mildly heterogeneous parenchyma without mass or nodule.ISTHMUS: Mildly heterogeneous parenchyma without mass or nodule.LYMPH NODES: No adenopathy noted.OTHER: No significant abnormality noted.
1. Nodule in the right lobe as described above. Although there are some spongiform characteristics, it is largely uniformly hypoechoic and amenable to biopsy.2. Mildly heterogeneous parenchyma raises the possibility of chronic thyroiditis.
