[Bilateral choroidal osteoma in an aged patient]

Area of Science:

• Ophthalmology
• Medical Imaging
• Oncology

Background:

• Choroidal osteoma is a rare, benign bone tumor of the choroid.
• It typically affects young females, making this elderly male case atypical.
• Bilateral and multifocal presentations are uncommon.

Observation:

• Bilateral and multifocal choroidal osteoma was diagnosed in an elderly patient.
• Diagnostic tools included retinal fluoroangiography, ocular ultrasonography, Computerized Axial Tomography (CAT), orbit Nuclear Magnetic Resonance (RNM), and electroretinography.
• Ocular ultrasonography and CAT scans were crucial in identifying the osseous nature of the tumor.

Findings:

• Ultrasound revealed dense opacities and decreased echo amplitude in the retrobulbar area.
• A-scan showed high reflectivity peaks, while CAT detected calcified areas.
• Follow-up imaging showed no significant changes, except for a slight increase in the right eye's central lesion.

Implications:

• The patient's age and sex challenge existing hypotheses on osteogenesis inhibiting factors and endocrine stimulation.
• This case highlights the importance of advanced imaging in diagnosing atypical presentations of choroidal osteoma.
• Further research is needed to understand the pathogenetical factors in elderly patients with this condition.
