Challenges in diagnosing disseminated congenital tuberculosis in a neonate: outcome and maternal treatment opportunity.

In India, congenital tuberculosis (TB) accounts for 1%-3% of the TB burden. We present the case of a term neonate admitted with respiratory distress, hepatosplenomegaly and abnormal coagulation profiles. The neonate's condition rapidly deteriorated, progressing to respiratory failure within 72 hours of admission. Tuberculosis-specific tests (TB PCR and culture) in the neonate confirmed the diagnosis of disseminated congenital TB. However, the results arrived after the neonate succumbed to multiorgan failure following a brief hospital stay. Maternal chest imaging after these results revealed miliary TB and she was started on anti-TB treatment. Despite the concerning signs, congenital TB was not initially suspected due to the absence of relevant maternal history and the overlapping features with other infections. As a result, the initial differentials considered were bacterial sepsis, perinatal viral infections and immunodeficiency. This case underscores the need for earlier suspicion of congenital TB, particularly in TB-endemic areas, to avoid adverse outcomes.
