The case report describes an unusual case of the resistance of the neck caused by bleeding into the parathyroid adenoma. A 72-year-old female patient was examined for resistance of the neck, differential diagnosis was a thyroid tumor.
At the same time, primary hyperparathyroidism was confirmed by the patient. During surgery, a rigid node corresponding to the haemorrhagically altered parathyroid adenoma was removed from the cervical incision.
Although the cause of the resistance of the neck is rarely the parathyroid adenoma, the endocrinologist or surgeon should think of it.
