Imaging choroidal osteoma with the Deep Range Imaging Optical Coherence Tomography – a case report

Area of Science:

• Ophthalmology
• Medical Imaging
• Oncology

Background:

• Choroidal osteoma is a rare, benign choroidal tumor predominantly affecting young females.
• Accurate diagnosis is crucial, with differential considerations including amelanotic choroidal melanoma and metastatic tumors.
• Ophthalmoscopy, ultrasound, and advanced imaging are vital for diagnosis.

Observation:

• This case report details choroidal osteoma features visualized with Deep Range Imaging Optical Coherence Tomography (DRI-OCT).
• DRI-OCT imaging highlighted the tumor's lamellar and spongy bone structure.
• Key observed features included the sclero-choroidal junction, tumor transparency, and communicating canals.

Findings:

• The study identified characteristic lamellar and spongy bone patterns within the choroidal osteoma.
• DRI-OCT revealed parallel horizontal and vertical canals within the lesion.
• Both calcified and decalcified regions were discernible using this advanced imaging technique.

Implications:

• Deep Range Imaging Optical Coherence Tomography offers detailed insights into choroidal osteoma's internal architecture.
• This imaging modality aids in differentiating choroidal osteoma from other posterior pole tumors.
• Enhanced visualization may improve diagnostic accuracy and management strategies for this rare condition.
