Plain-English summary
A 56-year-old woman who rides horses and has a lot of contact with dogs and wild animals was found to have a yellow mass in her eye that raised concerns. Doctors examined her eye and found a thick, elevated area that looked unusual but did not show signs of fluid buildup. They tested her for various infections related to animals, but all results came back negative. After monitoring her condition for six months, the mass remained stable, suggesting that it is not causing any immediate problems.
Abstract
PURPOSE: To describe solitary idiopathic choroiditis in the setting of extensive animal exposure. METHODS: A 56-year-old asymptomatic female equestrian with an extensive history of exposure to horses and dogs and a trapper of wild animals and rodents was discovered to have an amelanotic choroidal mass in the macular region and referred for suspicious atypical nevus. RESULTS: Funduscopy revealed a deep yellow mass with overlying retinal pigment epithelial thinning and without visible subretinal fluid or lipofuscin. Mild hyperautofluorescence represented unmasking of scleral autofluorescence. Ultrasonography showed a 1.8-mm-thick echodense lesion. Enhanced depth imaging-optical coherence tomography disclosed a dense, elevated scleral mass with "volcanic" configuration, demonstrating choroidal compression and trace overlying subretinal fluid. These features were consistent with solitary idiopathic choroiditis/scleritis. Systemic evaluation for standard cat-related bartonellosis, tuberculosis, sarcoidosis, and syphilis were negative. Horse-, dog-, and rodent-related bartonellosis testing was not available. Observation was advised, and the findings remained stable at 6 months. CONCLUSION: Solitary idiopathic choroiditis is best imaged on enhanced depth imaging-optical coherence tomography as a scleral lesion with "volcanic" configuration and often secondary to previous Bartonella infection. Serologic positivity for cat-related Bartonella decays over time, and testing for horse-, dog-, or rodent-related Bartonella is not commonly used.
