The most clinically significant complication associated with stereotactic core needle biopsy of the breast is hematoma formation, which only occurs in less than 1% of biopsies and may require treatment. Cases of uncontrollable bleeding, refractory to repeated compression, resulting from biopsy are exceedingly rare. We present a case of catastrophic, uncontrollable bleeding and large hematoma formation resulting from stereotactic vacuum-assisted breast biopsy of a breast mass identified in screening mammography. Percutaneous embolization was planned and guided using 3D reconstructions from computed tomographic angiography, and bleeding was successfully controlled with micro-coil embolization.
