A rare case of sever primary hypoparathyroidism presented with amnesia and basal ganglia calcification.

OBJECTIVES

The aim of this study was to describe clinical findings in a 45-year-old man with history of two sided cataract surgery, convulsions and progressive memory impairment.

METHODS

The patient presented to the neurology department because of having progressive memory impairment over the past two years. After taking necessary examinations the patient was referred to the endocrine center because of hypocalcemia in laboratory tests. Brain CT scan and MRI was also done.

RESULTS

Brain CT scan of patient showed extensive and symmetric calcification of basal ganglia, thalami and cerebellum. On Brain MRI, abnormal signal foci in the both sided paraventricular regions, basal ganglia and cerebellar hemisphere were depicted. Laboratory investigations were notable for low serum calcium (5.4 mg/dl, reference range: 8.2-11.2), high serum phosphorus (7.6 mg/dl, reference range: 2.7-4.5), vitamin D deficiency (25-OH D3: 14.5 ng/ml) and low parathyroid hormone (IPTH: 3.7 pg/mL, reference range: 10-62).

CONCLUSIONS

This patient presented with amnesia which is a rare presentation of hypoparathyroidism.
