Ectopic parathyroid is found in 16% of patients with hyperparathyroidism. 2% of ectopic parathyroid adenomas are not accessible to standard cervical excision. In such cases, video-assisted thoracoscopic resection is the recommended definitive treatment. We present a case of mediastinal parathyroid adenoma localized preoperatively by injecting methylene blue within a branch of the internal mammary artery that is supplying the adenoma. Intra-arterial methylene blue injection facilitated visualization and resection of the adenoma. The preoperative intra-arterial infusion of methylene blue appears to be an effective and safe method for localization of ectopic mediastinal parathyroid adenomas and allows rapid identification during thoracoscopic resection.
