Abstract
PURPOSE: To report a case of subarachnoid hemorrhage-negative Terson syndrome following intracranial artery treatment with flow diverter stents. OBSERVATIONS: A 40-year-old Asian woman presented with floaters in her right eye after treatment of an intracranial aneurysm with flow diverter stents. Vitreous hemorrhage and sub-inner limiting membrane (sub-ILM) hemorrhage were present in her right eye. On fluorescein angiography, contrast perfusion and vascular occlusion were not noted. Magnetic resonance imaging (MRI) did not show any evidence of subarachnoid hemorrhage (SAH). We hypothesize that the bleeding was due to Terson syndrome associated with intracranial treatment with the flow diverter stents. During follow-up, the vitreous hemorrhage and sub-ILM hemorrhage disappeared, and the floaters in her vision improved. CONCLUSIONS AND IMPORTANCE: This is the first reported case of vitreous hemorrhage and sub-ILM hemorrhage that should be considered to be Terson syndrome, after flow diverter stents treatment in the absence of SAH.
