Percutaneous abscess drainage and percutaneous biopsy are effective and widely used
techniques in the diagnosis and treatment of patients with abdominal or pelvic abscesses
and lesions. Some abscesses and lesions can initially appear unsuitable for percutaneous
access for a variety of reasons. This article reviews the circumstances in which collections
or lesions may appear undrainable or inaccessible to percutaneous biopsy, and it describes
techniques for overcoming these circumstances.
