目的研究超声在甲状腺良性钙化性结节(BCNS)和恶性钙化性结节(MCNS)鉴别诊断中的价值。方法回顾经病理证实的392例464枚甲状腺钙化性结节的超声表现,分析微钙化、粗钙化、环状钙化、混合钙化、微钙化+混合钙化在BCNS和MCNS中的分布。结果 464枚甲状腺钙化性结节中,382枚BCNS,82枚MCNS,微钙化、微钙化+混合钙化及粗钙化在二者之间具有统计学差异,微钙化及微钙化+混合钙化更常见于MCNS中,粗钙化更常见于BCNS中;环状钙化及混合钙化在二者之间无统计学意义。结论微钙化有利于MCNS的诊断,粗钙化提示BCNS的诊断,尽管混合钙化在二者之间无统计学意义,但将其并入微钙化,可明显提高MCNS诊断的灵敏度和阴性预测值,减少MCNS漏诊的发生率。关键词
Objective To study the value of ultrasound in differential diagnosis of benign thyroid calcified nodules (BCNS) and malignant calcified nodules (MCNS). Methods The pathologic findings of 464 thyroid calcified nodules were retrospectively analyzed. The distribution of microcalcifications, coarse calcifications, annular calcifications, mixed calcifications, microcalcifications and mixed calcifications in BCNS and MCNS were analyzed. Results Of 464 thyroid calcified nodules, 382 BCNS, 82 MCNS, microcalcification, microcalcification + mixed calcification and coarse calcification were statistically different between the two groups. Microcalcifications and microcalcifications + mixed calcification were more common in In MCNS, coarse calcification was more commonly found in BCNS; cyclic calcification and mixed calcification were not statistically significant between the two. Conclusions Microcalcifications is helpful for the diagnosis of MCNS. Coarse calcification indicates the diagnosis of BCNS. Although mixed calcification is not statistically significant, the combination of microcalcification and microcalcification can significantly improve the sensitivity and negative predictive value of MCNS diagnosis and reduce the incidence of MCNS Misdiagnosis of the incidence.
