Solid – Isoechoic and Hypoechoic
This 37 year old female presents with single nodule in the left lobe of the thyroid. Ultrasound of the mass in sagittal (a) and transverse view (b) reveals a complex mass with isoechoic and hypoechoic nodular components. The normal thyroid tissue is seen superiorly in image a and medically in image b. In the sagittal view there also appears to be a small shadowing macrocalcification (arrow). The halo is seen partly around the superior aspect on the sagittal view and shows no definite irregularity. The Doppler study shows mostly a peripheral pattern but some prominent central vessels are shown. There are no definite criteria to suggest malignant disease but in view of the size, age and vascular pattern biopsy was performed and showed a follicular adenoma.
