Abstract:
Objective To summarize the CT features of anaplastic thyroid carcinoma (ATC).Methods CT manifestations of 12 patients with ATC confirmed by surgery or biopsy were analyzed retrospectively.Results 1 1 (91.7%)patients had single lesion. The lesions appeared as low attenuation mass with cord-like,flocculent or patchy high attenuation areas.The lesions had mild to moderate enhancement in 1 1 cases (91.7%).Coarse calcifications were detected in 8 cases (66.7%),4 of them were incomplete rim or eggshell.11 cases (91.7%)showed invasion into adjacent structures,including trachea (6 cases,50%),esophagus (4 cases,33.3%),strap muscles (7 cases,58.3%),larynx (2 cases,1 6.7%),blood vessels (6 cases,50%).5 cases (41.7%)had tumor thrombus in the internal jugular vein.10 cases (83.3%)had lymph nodes metastasis.The enhancements of lymph nodes were divided into 3 types:mild homogeneous enhancement (4 cases,40%),mild enhancement with internal low-attenuation areas (7 cases,70%)and ring-like enhancement without internal enhancement (7 cases,70%).Conclusion CT features of ATC include low-density mass with cords,flocculent and patchy high-density areas,coarse calcification and mild to moderate enhancement,invasion to adjacent structure and lymph node metastasis with necrosis are common.
