Malignant seeding of the tract after thin-needle aspiration biopsy

Radiology. 1979 Feb;130(2):345-6. doi: 10.1148/130.2.345.


Fine-needle aspiration biopsy is an established technique for cytodiagnosis of malignant neoplasms, yielding a high rate of positive tissue with negligible local sequelae. The authors report the first instance known to them of needle tract seeding following this biopsy technique in a patient with an unresectable pancreatic carcinoma. Because of the rarity of this occurrence, the procedural indications remain unaltered.
