Congenital toxoplasmosis rarely occurs in infants born to mothers with evidence of prior immunity. We report the case of a preterm infant with severe ocular and neurological manifestations of congenital toxoplasmosis, despite maternal seropositivity (IgG+/IgM–) during pregnancy. This case highlights the potential for reactivation or reinfection with virulent strains and reinforces the need for vigilance and preventive strategies throughout pregnancy.
