Hypercalcaemia is uncommon among patients with pulmonary tuberculosis
in Hong Kong, possibly because of the low dietary calcium intake in th
is population. We report here a case of severe hypercalcaemia in a pat
ient with miliary tuberculosis and impaired renal function. We suggest
that tuberculosis should be excluded in any febrile patient with hype
rcalcaemia, particularly in countries where it is still a common condi
tion and an important cause of hypercalcaemia.
