Acquired toxoplasmic chorioretinitis.
A patient developed an acquired toxoplasmic chorioretinitis 11 days after exposure to infected animals. As systemic manifestations of the disease, the patient had rhinitis, sore throat, muscular pains, fatigue, cervical lymphadenopathy, and cardiac symptoms, with highly elevated Toxoplasma antibody titers. During treatment with prednisone, the chorioretinal lesion progressed to the macular area, but improvement was seen when pyrimethamine and sulfonamide therapy was started. The importance of this case relates to the unusual occurrence of acquired infection with systemic manifestations in toxoplasmic chorioretinitis and to the possibility of the transmission of toxoplasmosis by trophozoites in excretions.
