摘要

Purpose

To report a case of idiopathic vortex vein dilatation diagnosed using multimodal imaging, including indocyanine green angiography (ICGA), sodium fluorescein angiography (FFA), wide-angle color fundus photography, fundus autofluorescence (FAF), and ocular ultrasound.

Methods

Vortex vein dilatation is a clinically rare phenomenon, often incidentally detected during imaging. Its characteristic fundus appearance can mimic choroidal tumors or vascular lesions, potentially leading to unnecessary intervention. Current literature lacks sufficient reports of idiopathic cases and detailed descriptions of their imaging characteristics. We describe a 51-year-old male patient with an abnormal fundus finding in the left inferotemporal quadrant during routine examination. Multimodal imaging (color fundus photography, ocular ultrasound, FFA, and ICGA) excluded secondary causes, confirming a diagnosis of idiopathic cystic vortex vein dilatation.

Conclusion

Idiopathic vortex vein dilatation exhibits distinctive multimodal imaging features. These findings provide diagnostic criteria to assist clinicians in achieving an accurate diagnosis and avoiding misdiagnosis.
