PURPOSE: Nuclear medicine imaging can provide a noninvasive means of distinguishing inflammatory mass lesions from oncologic intraocular tumors.
OBSERVATION: We report a case of paraneoplastic ocular sarcoidosis with choroidal mass lesions that was initially concerning for choroidal metastasis of a primary carcinoid tumor. PET CT was utilized with two different tracers to characterize the choroidal mass as being FDG-avid, consistent with a sarcoid-like lesion, and lacking the Gallium (Ga-68) DOTATAE uptake of carcinoid tumor metastases.
CONCLUSIONS AND IMPORTANCE: Functional imaging is valuable to distinguish clinically similar inflammatory verses oncologic intraocular pathology.
