A right-sided thyroid gland lobe expansile, mixed pattern nodular lesion with cystic and solid mural parts with the solid area demonstrating an eccentric configuration and isoechoic reflectivity to the rest of the normal thyroid glandular parenchyma is noted. Peripheral borders of the mural part are gently lobulated, however, with acute angling at the nodular pedicle.
Colour flow Doppler mapping yields a centripetal flow pattern and, accompanying mid-level echoes is appreciated within the fluid-filled cystic expanse. The nodule is relatively retrosternal extended into the thoracic inlet as well. The isthmus body and the left thyroid lobe was unremarkable, with initial ultrasound findings given TIRADS category 3 assessment.
