PURPOSE
To highlight the computed tomography (CT) and magnetic resonance imaging (MRI) characteristics of lacrimal gland adenoid cystic carcinoma.
METHODS
We reviewed the clinical records and imaging findings of 17 patients who were histopathologically diagnosed with primary adenoid cystic carcinoma of the lacrimal gland between August 1998 and November 2010. Orbital CT scans were performed in 17 patients and MRI scans were obtained in 13 patients.
RESULTS
On the CT scans, out of 4 cases of adenoid cystic carcinoma, 3 showed characteristic features of a soft tissue mass with poorly enhancing areas representing cystic changes, and 4 of 17 cases had contiguous bony erosion. On the MRI scans, all cases had mixed signal intensity on T2-weighted images, and 6 cases showed poorly enhancing areas.
CONCLUSIONS
Enhanced CT and MRI (including T2-weighted) are helpful in the diagnosis of primary adenoid cystic carcinoma of the lacrimal gland.
目的
强调泪腺腺样囊性癌的计算机断层扫描（CT）和磁共振成像（MRI）特征。
方法
我们回顾了1998年8月至2010年11月期间17例经组织病理学诊断为原发性泪腺腺样囊性癌患者的临床记录和影像学表现。17例患者进行了眼眶CT扫描，13例患者进行了MRI扫描。
结果
在CT扫描中，4例腺样囊性癌患者中，3例表现为软组织肿块的特征性表现，强化不佳区域代表囊性改变，17例中有4例伴有相邻骨质侵蚀。在MRI扫描中，所有病例在T2加权图像上均表现为混合信号强度，6例显示强化不佳区域。
结论
增强CT和MRI（包括T2加权）有助于泪腺原发性腺样囊性癌的诊断。
