Objective To explore the manifestations and features of multi-slice spiral CT (MSCT) in the diagnosis
of papillary thyroid carcinoma (PTC).
Methods Preoperative MSCT data of 35 cases of PTC proved by operation and pathology in our hospital form May. to Jun. in 2013 were observed retrospectively, to analyze the manifestations and characteristics of MSCT for it.
Results Of 35 patients with PTC, MSCT totally showed 48 lesions, 68.6% (24/35) of patients with single lesion, 31.4% (11/35) of patients with 2-3 lesions, and 62.9% (22/35) of patients with lymph node metastasis. Of the 48 lesions, 29.2% (14/48) of lesions located in the left lobe, 70.8% (34/48) of lesions located in the right lobe;the lesions’ maximum diameter were 0.4-5.8cm, with the average maximum diameter of 1.3cm. There were 39.6% (19/48) of lesions with uneven density, 25.0% (12/48) of lesions with irregular shape, 47.9% (23/48) of lesions with blurred edges, 18.8% (9/48) of lesions had papillary enhanced tumor nodules, 10.4% (5/48) of lesions had peritumoral incomplete enhanced ring sign, 22.9% (11/48) of lesions invaded surrounding tissue or organs. There were 35.4% (17/48) of lesions had calcification, in which 76.4% (13/17) of lesions were fine granular calcification, 11.8% (2/17) of lesions were mixed calcification, and 11.8% (2/17) of lesions were coarse calcification.
Conclusion MSCT manifestations of PTC have certain characteristics, which can provide imaging basis for clinical treatment options.
