Musculoskeletal ImagingPseudohypoparathyroidism
an endocrine abnormality in which patients have the phenotypic features characteristic of
hypoparathyroidism but in whom the
parathyroid glands are essentially normal. The typical clinical features include short stature, round face, short neck, and shortening of metacarpal bones with low serum calcium and high serum phosphorus levels. However, in pseudohypoparathyroidism
parathyroid hormone levels are elevated, perhaps owing to the ineffective hormone action at the kidney with secondary hyperphosphatamia and hypocalcaemia (
Fig.1 and
Fig.2).
