【摘要】：目的探討腮腺腺泡細(xì)胞癌(ACCP)的CT、MRI表現(xiàn)。方法搜集經(jīng)手術(shù)病理證實的20例ACCP患者的CT和MRI資料(14例CT檢查,6例MRI檢查),回顧性分析腫瘤的部位、大小、形態(tài)、邊緣、CT密度或MRI信號及強(qiáng)化形式,并與病理結(jié)果相對照。結(jié)果 20例均為單發(fā)腫瘤,16例位于腮腺淺葉,4例位于腮腺深葉。病灶最大徑3 cm者18例,呈邊緣光整、類圓形或橢圓形腫塊,病灶與周圍組織分界清晰;3 cm者2例,呈邊緣不光整、不規(guī)則分葉狀腫塊,病灶周圍脂肪間隙模糊,其中1例侵犯耳前皮膚,1例包繞下頜后靜脈。密度(信號)均勻4例,不均勻16例。14例CT平掃病灶呈稍低密度5例,等密度9例;6例MRI病灶信號T1WI呈等信號,T2WI呈混雜高信號。增強(qiáng)掃描病灶呈明顯強(qiáng)化15例,中度強(qiáng)化3例,輕度強(qiáng)化2例。結(jié)論 ACCP的影像表現(xiàn)不具有特征性,確診最終依靠病理,CT、MRI檢查可以準(zhǔn)確顯示病灶的范圍,為臨床制定治療方案提供客觀依據(jù)。
[Abstract]:Objective to investigate the CT and MRI findings of acinar cell carcinoma of parotid gland (ACCP). Methods CT and MRI findings of 20 patients with ACCP proved by operation and pathology were collected. The location, size, morphology, edge CT density or MRI signal intensity and enhanced form of the tumor were analyzed retrospectively in 6 patients with MRI. The results were compared with pathological findings. 16 cases were located in the superficial lobe of parotid gland, 4 cases were located in the deep lobe of parotid gland. 3 cm was found in 2 cases, with irregular lobular mass and blurred fat space around the lesion. One case involved the anterior ear skin in 1 case and surrounded the posterior mandibular vein in 1 case. The density (signal) was uniform in 4 cases. The CT plain scan showed slightly low density in 5 cases and isodensity in 9 cases. In 6 cases of MRI, the signal intensity of T1WI showed mixed hyperintense signal on T1WI, 15 cases showed obvious enhancement on enhanced T1WI, and 3 cases showed moderate enhancement on T1WI. Conclusion the imaging findings of ACCP are not characteristic. To provide objective basis for clinical treatment.

【正文快照】： 腺泡細(xì)胞癌(acinic cell carcinoma,ACC)是一種少見的涎腺上皮源性惡性腫瘤,占所有涎腺腫瘤的3.4%,涎腺惡性腫瘤的12%~17%,約83%發(fā)生在腮腺[1,2]。1953年由Foote和Frazell首次系統(tǒng)描述并命名,過去曾稱為腺泡細(xì)胞腺瘤、漿液腺泡腺瘤等,1972年在WHO涎腺腫瘤的分類中被列為獨立的
