Objective To explore the CT manifestations with corresponding pathologic results of the papillary thyroid carcinomas (PTC) and to improve the CT diagnostic accuracy. Methods The CT findings of 16 PTC patients which confirmed by pathology were retrospectively analyzed and compared with pathological findings. Results In 16 cases,13 cases were solid tumors, and 3 cases contained both solid and cystic components. The maximal diameters of tumors ranged from 0.75cm to 4.6cm (mean 3.3cm). Tumor density was lower than that of normal thyroid tissue both on plain and enhanced CT imaging. 6 cases (37.5%, 6/16) contained scattered round granular calcification inside tumors. The margins of tumors were blurry, and the edge of the thyroid around tumors discontinuous in 13 cases. The margins of tumors were distinct in 3 cases which were follicular subtype of PTC in pathology.The enhanced degree of the smaller tumors was significantly lower than the bigger ones in 4 cases. Conclusion Combined with the distribution and form of calcification and the clinical features, the unique CT characteristics of PTC could improve its iagnostic accuracy.
