Toxoplasmosis transmitted to a newborn from the mother infected 20 years earlier.
OBJECTIVE
To present a case of congenital toxoplasmosis in a newborn whose mother had a 20-year history of a chorioretinal macular scar and positive serology for toxoplasmosis.


METHODS
Case report. SETTING/RESULTS: A 38-year-old woman who had been treated for ocular toxoplasmosis 20 years earlier delivered a newborn who presented with a focal necrotizing retinochoroiditis characteristic of toxoplasmosis, as well as positive immunoglobulin (Ig) G and M serology for toxoplasmosis. The workup was negative for other entities.


CONCLUSIONS
This case suggests that women with old retinal scars due to toxoplasmosis and long-standing IgG antibodies to toxoplasmosis are also at risk of transmitting this disease to the fetus.
