PA is associated with low bone mineral density and osteoporosis. Hypocalcaemia is known to occur in 35-65% of decompensations, however the underlying pathophysiology remains unclear. PTH resistance has previously only been described in one case of hypocalcaemia in PA and we report the first use of ...
