摘要
目的研究腮腺腺淋巴瘤（以下简称腺淋巴瘤）在唾液腺。^99mTco^4-显像中的形态、功能等影像学特点，探讨唾液腺显像诊断腺淋巴瘤的应用价值。方法选取临床拟诊断腺淋巴瘤患者44例，分别进行唾液腺动静态显像及彩色B超检查，同时与病理结果做对照，评判唾液腺显像对腺淋巴瘤的诊断价值。所得数据用统计学软件SPSS16．0处理，四格表Х^2检验。结果术后病理证实腺淋巴瘤32例，多形性腺瘤10例、绒毛状腺瘤l例、腮裂囊肿1例；核素显像发现阳性病例32例（分泌相“热结节”），病灶46个，单发22例，多发10例；12例阴性结果（包括1例“冷结节”，11例“温结节”）；灵敏度96．88％（31／32），特异性91．67％（11／12），阳性预测值96．88％（31／32），阴性预测值91．67％（11／12），准确性95．45％（42／44）。B超检查44例患者中，20例为阳性结果，24例为阴性结果；与病理对照，灵敏度46．88％（15／32），特异性54．55％（6／11），阳性预测值75．00％（15／20），阴性预测值25．00％（6／24），准确率47．72％（21／44）。两种方法差异有统计学意义（P〈0．05）。结论唾液腺显像诊断腺淋巴瘤敏感性及特异性都显著高于彩色B超，诊断符合率好，为术前定性及定位提供良好的诊断价值。
Objective To stuty the imaging characteristics of papillary cystadenoma lymphomatosum on technetium-99m （ Tc-99m ） pertechnetate scintigraphy and to explore the value of ^99mTco^4-salivary gland scintigraphy on the diagnosis of papillary cystadenoma lymphomatosum. Methods 44 patients with clinically diagnosed papillary cystadenoma lymphomatosum received dynamic/static salivary gland scintigraphy and Doppler uhrasonography. The detection results were compared with the pathological findings. And the diagnostic value of salivary gland scintigraphy for papillary cystadenoma lymphomatosnm was evaluated. The obtained data were analyzed by the statistical software SPSS16.0 and tested by ,Х^2 test. Results Papillary cystadenoma lymphomatosum in 32 patients, pleomorphic adenoma in 10, villous adenoma in one, and branchial cleft cyst in one were confirmed by postoperative pathological examinations. The radionu- clide imaging revealed positive findings （ ＇hot nodules＇ at the secretory phase ）were in 32 patients, lesions in 46, single lesion in 22 and multiple lesions in 10, and negative findings in 12 （ including one case of cold nodule and 11 cases of warm nodules ）, with a sensibility of 96.88% （ 31/32 ）, a specificity of 91.67% （ 11/12 ）, a positive predictive value of 96.88% （ 31/32 ）, a negative predictive value of 91.67% （ 11/12 ）, and a accuracy of 95.45% （ 42/44 ）; Doppler uhrasonography showed 20 patients had positive findings and 24 had negative findings; as compared with pathological examination, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 46.88% （ 15/32 ）, 54.55% （6/11）, 75.00% （ 15/20 ）, 25.00% （ 6/24 ）, and 47.72% （21/44）, respectively. Statistical significance was found between the two methods. Conclusions The sensitivity and specificity of salivary gland scintigraphy in the diagnosis of papillary cystadenoma lymphomatosum are remarkably higher than those of Doppler uhrasonography. Scintigraphy has a higher coincident rate of diagnosis and has a better diagnostic value for preoperative localization and differential diagnosis.
