Abstract

Introduction: Brown tumors are uncommon osteolytic lesions directly related to the increased osteoclastic activity due to hyperparathyroidism.

Case report: A 37-year-old woman presented with hypercalcemia related to primary hyperparathyroidism. Multiple and bilateral maxillary osteolytic lesions showing intense fluorodesoxyglucose (FDG) uptake were noted in a positron emission tomography computed tomography (PET-CT). Diagnosis of maxillary brown tumors was discussed and confirmed by both orthopantomogram and magnetic resonance imaging. Left inferior parathyroid adenoma was detected by both cervical ultrasonography and parathyroid scintigraphy, and then surgically treated with consequent improvement of hyperparathyroidism.

Conclusion: Our case emphasizes the necessity of a multidisciplinary diagnostic approach to optimize the interpretation of the available imaging, especially in unusual and unrecognized pathology as brown tumors.
