Fig. 1From: Anaplastic thyroid carcinoma with chondrosarcomatous differentiation: a case reporta. Computed tomography image showing a mass, 4.5 × 4.0 × 4.5 cm in size, with calcification in the left thyroid lobe and two smooth and homogeneous nodules in the right thyroid lobe. The trachea is compressed and deflected toward the right side. b. Neck MRI showed that the epicenter of the left lobe mass was in the thyroid gland and it did not originate from the surrounding thyroid cartilage (the red arrow shows the thyroid cartilage, and the blue box shows the main body of the tumor). c. Gross examination showed that a gray, lobulated mass occupied the majority of the left thyroid lobe. The cut surface appeared gray with hard consistency. d. Two homogeneous, oval nodules in the right thyroid lobe appeared gray with hard consistencyBack to article page
