Summary
Optical coherence tomography (OCT) visualized the cavernous structure of a choroidal osteoma. This imaging technique is valuable for understanding choroidal osteoma evolution, especially with retinal pigment epithelium atrophy.
Area of Science:
- Ophthalmology
- Medical Imaging
Background:
- Choroidal osteomas are rare, benign tumors of the choroid.
- Understanding their cross-sectional structure is crucial for diagnosis and management.
Observation:
- A case report details the imaging of a choroidal osteoma in a 22-year-old woman.
- Fluorescein and indocyanine green angiography were performed alongside optical coherence tomography (OCT).
Findings:
- OCT revealed a creamy-white lesion with increased reflectivity and a cavernous structure.
- An adjacent orange lesion showed less reflectivity under intact retinal pigment epithelium.
- Higher reflectivity at the retinal pigment epithelium level obscured deeper tumor structures in some areas.
Implications:
- Optical coherence tomography (OCT) can depict the cavernous structure of choroidal osteomas.
- OCT is particularly useful in visualizing tumors during specific evolutionary stages, such as with retinal pigment epithelium atrophy and premature ossification.
