Background. To report an atypical case of a transient choroidal mass lesion with spontaneous resolution. Case Presentation. A solitary choroidal mass with an overlying neurosensory retinal detachment was seen in an otherwise healthy 31-year-old female. General physical examinations and serum chemistry were unremarkable. The patient had spontaneous resolution two weeks after initial examination without treatment. Conclusions. Inflammatory choroidal masses may be self-limited, but complete diagnostic measures must always be performed in these patients to distinguish between important causes such as tuberculosis, sarcoidosis, and tumors.
