[A case of brain abscess secondary to bisphosphonate-related osteonecrosis of the jaws in metastatic bone lesions from breast carcinoma].

Bisphosphonates have been used clinically as highly effective drugs in the treatment of hypercalcemia of malignancy, and bone metastasis of solid cancers. Despite these benefits, however, the emergence of bisphosphonate-related osteonecrosis of the jaws has become a growing and significant problem in a subset of patients receiving these drugs. We report a rare case of brain abscess secondary to BRONJ in metastatic bone lesions from breast carcinoma.
