Parathyroid carcinoma is the rarest endocrine malignancy, and treatment options are limited. In some cases, treatment may be postponed due to misdiagnosis or delayed diagnosis. Most patients present with insidious symptoms of hypercalcemia only. We report a 74-year-old woman with parathyroid carcinoma who had an atypical presentation on a sestamibi (MIBI) parathyroid scan, which showed negative uptake in the primary parathyroid lesion but positive uptake in the metastasized right hilar lymph node. The definitive diagnosis was reached with the assistance of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) of the right hilar lymphadenopathy. This case report may serve to remind clinicians of the challenges and pitfalls in the diagnosis of occult parathyroid carcinoma and present an alternative approach to reaching a definite diagnosis via EBUS-TBNA.
