Isoechoic Thyroid Nodule With Vascularity, Isoechoic nodules. 7. Thyroid nodule vascularity can With its complex embryological origin, the thyroid can be affected by various congenital, developmental, benign, and malignant pathologies. Although calcification can be seen in both benign and malignant processes, it is the ultrasound feature most closely associated with malignancy 1. Checking your browser before accessing pmc.
