Percutaneous needle biopsies are frequently used to evaluate focal lesions of the liver. Needle-tract implantation of @entity96 has been described in case reports, but the true risk for this problem has not been clearly defined. We retrospectively reviewed 91 cases of @entity96 during a 4-year period from 1994 to 1997. Data on diagnostic studies, therapy, and outcome were noted. Of 91 @entity1 with @entity96 , 59 @entity1 underwent percutaneous needle biopsy as part of their diagnostic workup for a @entity409 . Three @entity1 (5.1%) were identified with needle-tract implantation of @entity5 . Two @entity1 required en bloc chest wall resections for implantation of @entity96 in the soft tissues and rib area. The third @entity1 , who also received percutaneous @entity1068 injection of his @entity5 , required a thoracotomy and lung resection for @entity96 . Percutaneous needle biopsy of suspicious @entity99 should not be performed indiscriminately because there is a significant risk for needle-tract implantation. These biopsies should be reserved for those lesions in which no definitive surgical intervention is planned and pathological confirmation is necessary for a nonsurgical therapy.

Needle-tract implantation from XXXX : is needle biopsy of the liver always necessary?
