Intracranial Calcification With Congenital Rubella Syndrome in a Mother With Serologic Immunity

Abstract

We report a case of an infant with congenital rubella. The mother had received rubella vaccine at the age of 13 years. Rubella serology was performed on day 34 of pregnancy and the result was interpreted as being a positive titer. The patient was a girl born by cesarean section owing to intrauterine growth retardation and fetal distress after 37 weeks' gestation. A computed tomographic scan at 4 days of age showed several cortical low-density areas and calcifications of the periventricular area and basal ganglia. Magnetic resonance imaging (MRI) performed at 4 weeks of age showed almost similar findings. The infant had serum IgG and IgM antibodies against rubella. Rubella virus ribonucleic acid (RNA) was detected from the serum, urine, and cerebrospinal fluid of the infant. At 2 months of age, the patient showed severe bilateral hearing loss. At 12 months of age, she had mild mental retardation and developmental delay. (J Child Neurol 2003;18:296—297).
