Ruptured Retinal Arterial Macroaneurysm Secondary to Toxoplasmic Kyrieleis Arteriolitis: A Case Report

PURPOSE: The aim of this report was to describe multimodal ocular imaging findings in a patient who presented with a ruptured retinal arterial macroaneurysm (RAM) associated with toxoplasmic Kyrieleis arteriolitis. METHODS: We report the case of a 64-year-old man with a history of systemic hypertens...

description PURPOSE: The aim of this report was to describe multimodal ocular imaging findings in a patient who presented with a ruptured retinal arterial macroaneurysm (RAM) associated with toxoplasmic Kyrieleis arteriolitis. METHODS: We report the case of a 64-year-old man with a history of systemic hypertension and dense amblyopia of the left eye who presented with decreased vision and new floaters in the left eye. Color fundus photography, spectral-domain optical coherence tomography, fluorescein angiography, and indocyanine green angiography were used as diagnostic imaging tools. RESULTS: No signs of hypertensive retinopathy were noted in the right eye. Multiple chorioretinal scars characteristic of previous toxoplasmosis were revealed in the left eye, with one covering most of the macula. Periarterial plaques or Kyrieleis arteriolitis were observed in retinal arteries surrounding the toxoplasmic retinal scars. Multiple RAMs were observed in these vessels, one of which was acutely ruptured. A perivenular plaque associated with a chronic branch retinal vein occlusion (BRVO) was noted along the same arcade at the arteriovenous crossing. CONCLUSION: RAM formation and BRVO can present as possible long-term complications of toxoplasmic Kyrieleis arteriolitis. This is the first reported case demonstrating an association between toxoplasmic Kyrieleis arteriolitis and RAM formation.
