Abstract: 目的: 探讨腮腺淋巴上皮病的影像学表现.方法:选取临床手术病理证实的 8例腮腺淋巴上皮病病例,采用 SIEMENS SOMATOM PLUS4螺旋 CT机和 SHIMADZU 4500T CT机,作平扫和增强扫描, 3例作延时扫描.结果:肿块 6例,强化明显,为均匀强化,或外周强化、中央次强化区.合并腮腺肿大 4例. 2例为单纯腮腺肿大.均表现为腮腺体积的增大和密度增高,并可见有点状、小囊状低密度影.和 (或 )伴有细小的结石或钙化影 2例.合并两侧泪腺肿大 1例.合并咽淋巴环增厚 2例.鼻咽淋巴组织增生 1例.伴颈部或颌下淋巴结肿大 5例.结论:非类肿瘤型腮腺淋巴上皮病结合临床特点大多数可以作出诊断.而类肿瘤型腮腺淋巴上皮病在临床和影像上均缺乏特征.良、恶性淋巴上皮病在影像上鉴别困难.针吸活检仍是目前最可靠的术前诊断手段.
