Ocular Toxoplasmosis: No Stranger to the Masquerade Ball

Purpose: This article illustrates multiple atypical manifestations of ocular toxoplasmosis masquerading as acute retinal necrosis and vitreoretinal lymphoma. Methods: Two case presentations are discussed, and the body of pertinent literature is reviewed and discussed. Results: In these cases, an extensive workup and attention to history lead to the correct diagnosis and management. Conclusions: Aggressive cases of ocular toxoplasmosis may present in a variety of phenotypes that may mimic other vision- and potentially life-threatening conditions, particularly in a milieu of inadequate endogenous and exogenous antimicrobial defenses.
