Abstract:
A case of intraorbital ectopic lacrimal gland was evaluated with various radionuclides. CT and MRI with contrast enhancement showed a soft-tissue mass in the orbit. The lesion was gallium-avid, but 18F-FDG PET demonstrated very faint uptake. On early and delayed 201Tl-Cl images, mildly increased uptake and mild retention were observed. Technetium-99m-(V)-DMSA SPECT showed intense accumulation on both the early and delayed images. Technetium-99m-pertechnetate SPECT, demonstrating marked uptake in the lesion, was useful for the differential diagnosis between intraorbital malignancy and this benign lesion. These scintigraphic variations played an important role in the tissue characterization of this uncommon lesion.
