title: Delayed Tumor Seeding Along Axillary Lymph Node Biopsy Tract Visualized on FDG PET/CT.
abstract: A 59-year-old woman with right breast cancer underwent an ultrasound-guided core needle biopsy of a right axilla lymph node. Pathology results revealed metastases from breast cancer. The patient had serial FDG PET/CT scans for further workup and therapy assessment during the disease course. Hypermetabolic tumor seeding along the needle biopsy tract was not evident at FDG PET/CT scan performed 5 weeks after biopsy but became apparent at 10 weeks after biopsy and progressed subsequently.
