ROENTGENOGRAPHIC DIAGNOSIS OF THYROID CANCER IN THE PRESENCE OF ENDEMIC GOITER

Abstract
The value of soft tissue roentgenography of the neck in patients with thyroid disease from an endemic goiter area was studied. In 47 patients with thyroid carcinoma, 21 with nodular parenchymatous goiter, 5 with colloid goiter and 2 with bacterial thyroiditis, soft tissue roentgenography facilitated the differential diagnosis only in tumors more than 70 gm. of estimated weight (Grade III and IV). It was found to be more difficult to distinguish colloid goiter and thyroiditis than nodular goiter from carcinoma by roentgenologic signs alone. Invasion of the trachea, anterior displacement of the trachea, calcifications, and small lateral displacement of the trachea in the presence of a large cervical mass were of value in the differential diagnosis in this sequence.
