Abstract:
To report the clinical, imaging and pathological feature of a case of primary hyperparathyroidism(PHPT) with multiple brown tumors whose complain was repeated epistaxis, and to conduct a retrospective analysis with relevant literatures. A postmenopausal middle-aged woman, with a history of joint pain, fracture, and kidney stone which were neglected due to the lack of specificity of symptoms for years, went to hospital due to repeated epistaxis. Laboratory results showed high blood calcium, hypophosphatemia, alkaline phosphatase(ALP), and parathyroid hormone(PTH) levels, as well as increased urinary calcium. Imaging examination showed systemically multiple brown tumors and extensive osteoporosis. Meanwhile an abnormal mass was found behind the right thyroid. Taking all findings into account, the diagnosis was made with PHPT, and the histopathology further confirmed that the lesion was a parathyroid adenoma. This case seems to be a rare case of multiple brown tumor caused by parathyroid adenoma, which compressed and destructed nasal blood vessels, thus induced a repeated nasal discharge. After resection of parathyroid adenoma, the patient experienced a transient hypocalcemia and PTH level elevation. After 5-month follow up, part of the brown tumors spontaneously regressed, bone density increased, and her clinical symptoms were mostly relieved.
