Congenital rubella syndrome with death from interstitial pneumonia.

There was a rubella epidemic in Japan in 2012-2013, which led to an increased number infants being born with congenital rubella syndrome (CRS). Symptoms of CRS are varied and include cataracts, congenital heart disease, and hearing impairment, but case reports of CRS complicated by interstitial pneumonia are rare. We report the case of a patient with CRS who died of respiratory failure caused by interstitial pneumonia. Thrombocytopenia had been present for approximately 1 month after birth, and the patient presented with sudden lung hemorrhage at 64 days old. Thereafter, respiratory condition deteriorated, and the patient died at 107 days old. Given that infants with CRS who have thrombocytopenia and interstitial pneumonia have a high risk of death, they should be monitored carefully for potential complications.
