Abstract

Pseudohypoparathyroidism
is characterized by hypocalcemia, hyperphosphatemia, increased serum
parathyroid hormone values and insensitivity to the biological activity of
parathyroid hormone. Pseudohypoparathyroidism is often associated with a
characteristic phenotype known as Albright‘s hereditary osteodystrophy.
Pseudohypoparathyroidism usually presents at an early age. We describe a 50-year-old man who
presented with seizure
due to hypocalcemia. He has typical features of Albright's
hereditary osteodystrophy, which include a round face, short neck and
stature.  Diffuse
calsifications were seen on the bilateral cerebellum, putamen and
dentate nucleus in computerized tomography. The patient is treated successfully by calcium
carbonate and calcitriol supplementation
This case was reported in order to remind pseudohypoparathyroidism in patients
with hypocalcemic seizures.
