Percutaneous drainage of a tuberculous liver abscess

The authors describe the management by percutaneous drainage of a rare solitary tuberculous liver abscess in a 37-year-old woman. Open surgical drainage of such abscesses can be avoided using percutaneous drainage combined with transcatheter infusions of antituberculous agents. For the safe and successful use of this method three criteria must be met: the abscess should be unilocular, there must be a safe access route and a previously sterile compartment must not be contaminated. In addition a small (22 or 23 gauge) needle should be used for the initial puncture.
