Pseudohypoparathyroidism refers to end-organ resistance that primarily impairs the renal actions of parathyroid hormone (PTH), a key regulator of calcium homeostasis. Its diagnosis is complex because of the multiple variants of this entity, and more so because intravenous PTH is not available for the Ellsworth-Howard test. We report a symptomatic paediatric case of hypocalcaemia, the clinical features of which, and the course after treatment, suggest that it is most probably a case of pseudohypoparathyroidism type Ib.
