Munchausen syndrome by proxy: A new complication of central venous catheterization

A recent case of supposed gastrointestinal (GI) bleeding in a small child underscored the difficulty inherent in making the diagnosis of Munchausen syndrome by proxy. In this case, an indwelling Broviac central venous catheter was used by the mother to withdraw blood which was then arranged to feign blood loss from her son's upper and lower GI tract. Despite the mother/perpetrator's displaying the classic personality traits of Munchausen syndrome by proxy, diagnosis was not made for many weeks.
