title: Sebaceous lymphadenoma demonstrated by CT and MRI.
abstract: Sebaceous differentiation in normal salivary gland tissue is known to occur, but primary sebaceous neoplasms of the salivary gland are extremely rare. To the best of our knowledge, very few studies have described thin-section computed tomography (CT) and magnetic resonance (MR) imaging results in patients with sebaceous lymphadenomas. We describe a 75-year-old man with a sebaceous lymphadenoma of the right salivary gland. Thin-section CT images revealed a well-defined, inhomogeneous, low-density mass with scattered fat density areas, whereas dynamic MR images revealed a mass with fat intensity areas with an early enhanced and delayed washout pattern and an enhanced capsule.
