In an extended case report, we discuss four cases with masses in the lacrimal fossa representing the most important entities in this region (lymphoma, pleomorphadenoma, inflammatory pseudotumor, and malignant epithelial tumor). The different indications for CT and MRI are explained. For the differential diagnosis of lacrimal gland lesions, the following imaging parameters are important: the shape of the lacrimal gland, the inner structure, the degree of contrast enhancement, and the surrounding bony structures. In the evaluation of the expansion of lacrimal gland lesions, CT in thin slices with multiplanar reconstructions is equal to MRI. However, the contrast-enhancement of lacrimal glands is better evaluated with MRI than with CT. The bony structures are better visualized on CT than on MRI.
在一篇扩展病例报告中，我们讨论了4例泪腺窝肿物病例，这些肿物代表了该区域最重要的病变类型（淋巴瘤、多形性腺瘤、炎性假瘤和恶性上皮性肿瘤）。文中解释了CT和MRI的不同适应证。对于泪腺病变的鉴别诊断，以下影像学参数很重要：泪腺的形态、内部结构、对比增强程度以及周围骨质结构。在评估泪腺病变的范围时，薄层CT多平面重建与MRI效果相当。然而，MRI对泪腺对比增强的评估优于CT。骨质结构在CT上的显示优于MRI。
