Lacrimal Gland involvement in systemic Sarcoidosis

Abstract

Lacrimal gland lesions generallypresent as palpable masses in thesuperolateral aspects of the orbits. Approximately 50% of lacrimalgland masses are inflammatory lesions, 25% are lymphoid lesions or lymphoma, and the other 25% are salivary gland type tumors. Although there are overlaps and exceptions, features such as laterality, portion of gland involvement, presence or absence of bony findings, enhancement pattern, andclinical presentation are valuable in differentiating among lacrimal gland lesions. The 3D ultrasound has been used to define lacrimal gland shape, size, density, structural features the pattern of blood supply, as well as the anatomic and topographic position in the orbit. The study was conducted in the B- and 3D-modes of ultrasonography with color and energy Doppler mapping on both sides.
