Female 31 years old; Reason: History of enlarging mass on neck, history of nodule/1.3 cm on L now with enlarging thyroid b/l, assess for thyroiditis vs mass vs other RIGHT LOBE MEASUREMENTS: 4.2 x 2.9 x 7.8 cm (previously 3.9 x 2.5 x 9.0 cm)LEFT LOBE MEASUREMENTS: 3.5 x 2.6 x 6.6 cm (previously 3.4 x 2.7 x 8.3 cm)ISTHMUS MEASUREMENT: 0.37 cm (previously 0.47 cm)RIGHT LOBE: The thyroid is enlarged and heterogeneous. A nodule in the posterior aspect of the gland measures 1.0 x 0.8 x 1.1 cm, is mixed solid/cystic with no significant vascular flow and may have been present on the previous ultrasound although difficult to measure.LEFT LOBE: The thyroid is large and heterogeneous. In the left lower pole a mixed solid/cystic nodule is again seen which measures 1.2 x 0.7 x 1.0 cm (previously 1.3 x 1.0 x 1.3 cm). A second nodule more superiorly in the midpole is mixed solid/cystic and measures 1.2 x 0.6 x 1.0 cm.ISTHMUS: No significant abnormality noted.LYMPH NODES: A right level 2 lymph node measures 2.4 x 1.1 x 2.5 cm with a fatty hilum and lobular contour.
1.Diffusely large and heterogeneous thyroid gland compatible with thyroiditis.2.Dominant predominantly solid left lower pole thyroid nodule has decreased in size.3.Two nodules on the right may have been present on the previous study but were not as clearly visualized and may represent colloid nodules.4.Enlarged right level 2 lymph node has a benign appearance and is likely reactive, may be seen in setting of thyroiditis.
