Parathyroid adenomas (PAs) are the most common cause of primary hyperparathyroidism. Presentations can range from the classic bone pain, depression, fatigue, renal calculi, and gastrointestinal tract symptoms to asymptomatic calcium level elevation detected on a serum chemistry panel. They are benign tumors that are not generally thought to cause recurrent laryngeal nerve paralysis.
