Female 43 years old; Reason: r/o cystic structure. assess size. r/o adenopathy, growth of lesion History: h/o thyroid cancer. Had small cystic structure in neck, biopsied and mostly drained. Low Tg level, but atypical cells seen. This is a follow up study to see if cyst still visible, and for any other changes RIGHT LOBE MEASUREMENTS: Status post thyroidectomy.LEFT LOBE MEASUREMENTS: Status post thyroidectomy.ISTHMUS MEASUREMENT: Status post thyroidectomy.RIGHT LOBE: Subcentimeter hypoechoic focus in the right thyroid bed measures 0.4 x 0.3 x 0.2 cm (previous 0.3 x 0.3 x 0.3 cm).LEFT LOBE: No evidence of disease recurrence.ISTHMUS: No evidence of disease recurrence.LYMPH NODES: Hypoechoic focus in the left lateral neck level IV region which was previously aspirated is redemonstrated and currently measures 0.3 x 0.2 x 0.3 cm (previously 0.6 x 0.6 x 0.6 cm).
1.Persistent cystic structure in the left level IV region is smaller in size than on the prior ultrasound. Again, adequate tissue sampling would be difficult due to the cystic composition.2.No evidence of recurrence in the thyroid bed.
