Abstract
Purpose
The aim of our study was to describe the clinical presentation of an unusual evanescent, exudative, choroidal pseudo-tumor with acute painful onset, and propose a pathogenesis.
Methods
We carried out a retrospective, observational study using the case series of three patients presenting with an evanescent, exudative, choroidal pseudo-tumor with acute painful onset. Ultra-widefield fluorescein and indocyanine green angiography (ICGA) using the Heidelberg Retina Angiograph and the Staurenghi 230 SLO Retina Lens were used to propose a pathogenesis of this unusual entity.
Results
In all three cases, acute ocular pain led to discovery of an exudative, partially hemorrhagic choroidal mass (thickness 2.4 mm–4.1 mm on ultrasound) that quickly regressed within weeks. In the subacute phase, all patients showed choroidal circulation abnormalities on dynamic wide-field ICGA in the affected quadrant, with delayed arterio-venous filling in two patients, and a poorly-defined vortex vein in the third. The choroidal circulation abnormalities resolved within 8–12 weeks, simultaneously with the spontaneous resolution of the choroidal pseudo-tumor. The findings evoked a self-resolving vortex vein occlusion in the corresponding quadrants with acute, painful choroidal exudation.
Conclusions
An evanescent, exudative, hemorragic choroidal pseudo-tumor with acute painful onset may be caused by a vortex vein occlusion. Future patients need to be studied with ICGA in the acute phase to confirm this hypothesis.
