[Echography and percutaneous fine needle biopsy]

Echography, even if it is a procedure widely used in numerous protocols, is not devoid of diagnostic inaccuracy. However, when fine needle percutaneous biopsy is associated to echography, the diagnostic accuracy raises to 88%. This combined procedure is easily carried out, it is inexpensive, without discomfort to the patient and devoid of major complications. When it is performed, other more invasive techniques, such as arteriography or laparotomy may be useless. Methods of application and case-reports are illustrated.
