Undifferentiated carcinoma of the thyroid gland: sonographic findings.
We report high resolution sonographic (7.5 MHz) findings in four cases of undifferentiated carcinoma of the thyroid gland. Sonographic findings in these four cases included poorly marginated, hypoechoic masses associated with calcifications, and invasion of adjacent cervical structures. A knowledge of the sonographic features of undifferentiated carcinoma of the thyroid gland is of clinical importance, since the tumour has a grave prognosis, quite different from the relatively favourable prognosis of well differentiated thyroid carcinoma.
