Double maternal seroconversion to cytomegalovirus and Toxoplasma gondii.

BACKGROUND

We report the first case of a double maternal seroconversion for Toxoplasma gondii (TG) and cytomegalovirus (CMV) diagnosed during pregnancy.

CASE

One case is reported of a female patient referred for seroconversion in response to TG in the 27th week of gestation. A search for foetal involvement revealed signs of non-specific foetal infection without any TG-related lesions. Tests were carried out for another foeto-maternal infectious disease and maternal seroconversion in response to CMV was discovered with virus in the amniotic fluid. The foetus developed hydrocephalus and intracranial calcifications and the pregnancy was terminated at the parents' request. CMV-induced multiple organ involvement without any signs of Toxoplasma gondii-related involvement were noted in the foetus.

CONCLUSIONS

This case indicates that a search should be made for another infectious disease likely to involve the foetus when non-specific signs of infection in the foetus are present, even though maternal seroconversion has been recognized.
