Summary
Sclerochoroidal calcifications can mimic choroidal masses. Enhanced depth imaging optical coherence tomography (EDI-OCT) reveals unique features of these calcifications, aiding diagnosis.
Area of Science:
- Ophthalmology
- Medical Imaging
Background:
- Bilateral retinal lesions in an 85-year-old patient were initially suspected to be metastases.
- Diagnostic evaluation included slit-lamp biomicroscopy, funduscopy, fluorescein angiography, B-scan ultrasonography (U/S), and enhanced depth imaging optical coherence tomography (EDI-OCT).
Observation:
- B-scan U/S showed bilateral echo-dense choroidal consolidations with acoustic shadowing.
- EDI-OCT visualized hyper-reflective lesions with posterior decreased reflectivity.
Findings:
- The observed features were consistent with sclerochoroidal calcifications.
- EDI-OCT provided unique imaging characteristics of these lesions.
Implications:
- Sclerochoroidal calcifications should be considered in the differential diagnosis of choroidal masses.
- EDI-OCT is a valuable tool for identifying the characteristic appearance of sclerochoroidal calcifications.
