Congenital tuberculosis after in-vitro fertilisation.

A 6-week old infant who had been conceived through in-vitro fertilisation (IVF) presented with a skin lesion and enlarged lymph nodes, and developed severe respiratory distress. Mycobacterium tuberculosis was identified; his mother was the only potential source identified. To our knowledge, this is the first case of congenital tuberculosis after IVF reported in Australia and the second worldwide. It highlights the importance of adequate screening during investigation of infertility and the difficulties in diagnosing congenital tuberculosis.
