Abstract
Purpose
To report a case series of 3 patients with choroidal granulomas due to Bartonella henselae infection in order to raise awareness about this etiology in the differential diagnosis of choroidal granulomas.
Methods, patients
A retrospective case series of patients with choroidal granulomas due to Bartonella henselae infection who consulted between 2018 and 2020. Data were collected from the medical records (demographics, visual acuity (VA), laboratory tests, treatment, imaging).
Results
Patients were a 48-year old man, a 14-year old girl and a 31-year old man. They all had a choroidal granuloma seen on optical coherence tomography (OCT) and angiography. The laboratory work-up revealed a positive serology for Bartonella henselae in all patients.
Conclusion
On multimodal imaging choroidal granulomas in B Henselae appeared as single or multiple, uni or bilateral round yellowish lesions. Fluorescein and indocyanine green angiography of the granuloma showed respectively a late staining and a hypofluorescence. On EDI-OCT choroidal granuloma appeared as a round hyporeflective lesion in the choroid with a retinal elevation. The exclusion of other diagnosis, the natural course and the serology must lead the ophthalmologist to evoke the diagnosis.
