Reason: MYH-associated polyposis associated with increased risk thyroid cancer; mother with thyroidectomy History: surveillance; none RIGHT LOBE MEASUREMENTS: 5.8 x 2.3 x 2.4 cm.LEFT LOBE MEASUREMENTS: 4.9 x 1.8 x 1.9 cm.ISTHMUS MEASUREMENTS: 0.5 cm.RIGHT LOBE: Right mid pole nodule is heterogeneous and predominantly solid and measures 1.5 x 1.0 x 0.9 cm. No internal vascularity or microcalcifications.Right inferior pole nodule demonstrates similar characteristics, measuring 1.7 x 1.3 x 1.8 cm. No internal vascularity or microcalcifications.LEFT LOBE: The left thyroid is heterogeneous with numerous nodules which are predominantly cystic without internal vascularity or calcifications. Reference nodule measures 0.8 x 0.5 x 0.9 cm.ISTHMUS: Hypoechoic nodule in the junction of the stenosis in the left medial thyroid lobe measures 1.1 x 0.8 x 0.9 cm. This nodule is more solid with punctate hyperechoic foci which could be secondary to motion artifact, as on subsequent images it has a more spongiform appearance. Close attention on follow-up examinations is recommended. No significant internal vascularity.PARATHYROID GLANDS: Not visualized.LYMPH NODES: No significant abnormality noted. No cervical lymphadenopathy.OTHER: No significant abnormality noted.
Nodule at the junction of the isthmus and the left medial thyroid lobe warrants attention on follow-up examinations as described above. Other bilateral nodules without definite suspicious features.
