Summary
Routine toxoplasmosis screening missed congenital infection in a fetus. Early diagnosis and frequent serological testing are crucial for timely treatment to prevent severe infant complications like cerebral calcifications.
Area of Science:
- Medical Science
- Infectious Diseases
- Maternal-Fetal Medicine
Background:
- Congenital toxoplasmosis screening is vital for preventing severe neonatal outcomes.
- Early gestation screening for toxoplasmosis may yield false negatives.
- Timely diagnosis is critical for effective treatment of congenital infections.
Observation:
- A pregnant patient initially tested negative for toxoplasmosis at 13 weeks gestation.
- A subsequent test at 32 weeks gestation was positive, indicating infection.
- The infant presented with severe congenital toxoplasmosis lesions despite maternal chemotherapy.
Findings:
- Infection likely occurred between 17-24 weeks gestation, undetected until 32 weeks.
- Infant's severe lesions (cerebral calcifications, chorioretinitis) did not respond to treatment.
- Delayed diagnosis precluded effective intervention, highlighting a critical window for treatment.
Implications:
- Increased frequency of serological screening for toxoplasmosis is recommended after an initial negative result.
- Earlier detection of congenital toxoplasmosis is essential for improved infant prognosis.
- This case underscores the need for vigilant monitoring in suspected congenital infections.
