Purpose:
To report a case of a perifoveal exudative vascular anomalous complex (PEVAC) resembling lesion in a patient with multiple myeloma.
Observations:
A 56-year-old male with multiple myeloma presented with sudden moderate vision loss in the right eye. Best-corrected visual acuity was 20/25 in his right eye. Fundus examination showed a vascular irregularity in the perifoveal region. Fluorescein angiography (FA) revealed an isolated perifoveal aneurysmal lesion with minimal leakage. On optical coherence tomography (OCT) examination, a large oval structure with a hyperreflective wall and exudation was visualised. Three weeks later, spontaneous improvement of the intraretinal fluid was observed on OCT without treatment. However, 3 months later the macular edema recurred. The appearance of the aneurysmal lesion is similar to a PEVAC lesion, which is an isolated well-defined perifoveal intraretinal vascular abnormality presenting on OCT as a round hyperreflective structure with a dark lumen containing variably reflective material and is commonly associated with cystic intraretinal fluid.
Conclusions And Importance:
PEVAC was originally described as occurring in healthy patients, but recent observations suggest that it also appears in association with other retinal/choroidal vascular abnormalities or underlying cardiovascular abnormalities. Our case supports this hypothesis by demonstrating a PEVAC resembling lesion in a patient with multiple myeloma.
