Multinodular goiter with anterior mediastinal extension in a 40-year-old female. Contrast-enhanced computed tomography demonstrating a soft tissue mass with cystic areas and specks of calcifications in anterior mediastinum (
 A 
). Contrast axial (
 B 
) and coronal reformatted images (
 C 
) showing heterogeneous enhancement of the mass extending from neck into the anterior mediastinum. Histopathology (
 D 
) proved the mass to be multinodular goiter. Note the collections of variably sized and shaped follicles forming irregular lobules. The follicles are distended with colloid.
