Abstract
BACKGROUND

Hypoparathyroidism with basal ganglia calcification is clinically rare. Here, we report a case of Fahr’s syndrome due to hypoparathyroidism and review the literature in terms of etiology, clinical manifestation, diagnosis, and treatment.

CASE SUMMARY

A 62-year-old man experienced repeated twitching of both hands in recent 10 years. On July 28, 2017, the patient was admitted to our hospital due to slow response and speech difficulties. On medical examinations, he had a positive Chvostek sign, while no Albright’s hereditary osteodystrophy signs or history of neck surgery or radiation, and his family members had no similar medical history. Laboratory examinations revealed hypocalcemia, hyperphosphatemia, and low parathyroid hormone (PTH) levels. Computed tomography revealed basal ganglia calcification. Based on these investigations, a diagnosis of Fahr’s syndrome due to hypoparathyroidism was suggested. After receiving intravenous calcium gluconate to relieve symptoms, the patient continued to take oral calcium carbonate and calcitriol for treatment.

CONCLUSION

The possibility of hypoparathyroidism should be considered in patients with chronic hypocalcemia, recurrent tetany, and even neuropsychiatric symptoms. Hypoparathyroidism is a common cause of basal ganglia calcification. Therefore, it is recommended that blood calcium, phosphorus, and PTH levels should be measured in all individuals with basal ganglia calcification to exclude hypoparathyroidism.

Keywords: Hypoparathyroidism, Hypocalcemia, Fahr’s syndrome, Case report

Core tip: The clinical manifestations of hypoparathyroidism are complex and varied. Fahr's syndrome is diagnosed when basal ganglia calcification occurs. Fahr's syndrome is clinically rare. Here, we report a case of Fahr’s syndrome due to hypoparathyroidism and review the literature from etiology, clinical manifestation, diagnosis, and treatment. On the one hand, this case reflects the importance of standardized treatment and follow-up in patients with hypoparathyroidism. On the other hand, it is recommended that clinicians first consider the possibility of hypoparathyroidism when looking for the cause of basal ganglia calcification.
