Internal mammary lymph node biopsy guided by computed tomography

Abstract

SummaryInternal mammary lymph node enlargement may be demonstrated using computed tomography (CT), and a confirmatory tissue diagnosis of metastatic involvement may be obtained using fine needle aspiration biopsy with needle tip placement guided by the CT scanner. A case history is described to illustrate how a patient presented 9 years after mastectomy with an internal mammary lymph node metastasis and how cytopathological diagnosis of this metastasis was achieved by CT guided biopsy.
