Multifocal circumscribed choroidal hemangioma: a rare occurrence

Area of Science:

• Ophthalmology
• Medical Imaging
• Vascular Oncology

Background:

• Choroidal hemangioma (CCH) is a benign vascular tumor of the choroid.
• CCH typically presents as a solitary lesion.
• Multifocal CCH is exceptionally rare, with limited literature documenting its occurrence.

Purpose of the Study:

• To report a unique case of multifocal circumscribed choroidal hemangioma (CCH).
• To describe the clinical presentation and diagnostic findings of this rare condition.
• To contribute to the limited literature on multifocal CCH.

Main Methods:

• Clinical presentation of a 32-year-old woman with painless vision loss.
• Fundus examination revealing multiple subretinal lesions.
• Diagnostic confirmation using Indocyanine green angiography and optical coherence tomography.

Main Results:

• Identification of a large, dome-shaped, orangish-red subretinal lesion at the macula and a smaller lesion on the superotemporal arcade in the left eye.
• Multifocal CCH diagnosis confirmed by angiography and OCT.
• Absence of Sturge-Weber syndrome features.

Conclusions:

• Multifocal CCH is an exceedingly rare presentation of choroidal hemangioma.
• Advanced imaging modalities are crucial for diagnosing multifocal CCH.
• This case expands the understanding of CCH variability and emphasizes the importance of thorough investigation for rare presentations.
