【摘要】：目的:分析腮腺腺泡細(xì)胞癌的MRI圖像特點,進(jìn)一步提高該病在MRI上的診斷水平。方法:回顧性分析11例經(jīng)手術(shù)病理確診的腮腺腺泡細(xì)胞癌患者的MRI表現(xiàn)及臨床特點。MRI分析內(nèi)容包括腫瘤數(shù)目、部位、大小、形態(tài)、邊界、包膜、信號特點、增強掃描病灶強化特點、頸部淋巴結(jié)腫大情況等。臨床分析包括患者的年齡、性別及隨訪情況等。結(jié)果:11例患者均單側(cè)腮腺單發(fā),共11個腫瘤,右側(cè)腮腺7個,左側(cè)腮腺4個;腫瘤平均最大長徑(2.66±0.99)cm;7個腫瘤有分葉,4個呈類圓形;8例未見假包膜,3例顯示不完整假包膜。T1WI:腫瘤以等高信號為主;T2WI:腫瘤以高信號為主。增強掃描,明顯均勻或不均勻強化。結(jié)論:當(dāng)腮腺內(nèi)腫瘤未見包膜(或包膜顯示不完整)、有分葉、內(nèi)有小囊變以及明顯強化時,可能提示腮腺腺泡細(xì)胞癌,確診仍需結(jié)合臨床病理檢查。
[Abstract]:Objective: to analyze the MRI features of parotid acinar cell carcinoma and to improve the diagnostic level of the disease on MRI. Methods: the MRI findings and clinical features of 11 patients with parotid acinar cell carcinoma confirmed by operation and pathology were retrospectively analyzed. Enhanced scanning focus enhancement features, cervical lymph node enlargement and so on. Clinical analysis included age, sex, and follow-up. Results all the 11 cases were unilateral parotid gland with 11 tumors, 7 in the right parotid gland and 4 in the left parotid gland. The mean maximum length of tumor was (2.66 鹵0.99) cm, 7 tumors were lobulated, and 8 cases had no pseudocapsule. 3 cases showed incomplete pseudocapsule. T1WI: the tumor was characterized by isobaric signal and hyperintense. Enhanced scanning, obviously uniform or uneven enhancement. Conclusion: the diagnosis of parotid acinar cell carcinoma should be combined with clinicopathological examination when there is no capsule (or incomplete appearance of capsule), lobulation, small cystic degeneration and obvious enhancement of parotid gland acinar cell carcinoma.
