Introduction: The combination of hypokalemia and hypercalcaemia is uncommon but potentially lethal. In primary hyperparthyroidism hypokalaemia most commonly occurs due to incomplete distal renal tubular acidosis. We present the first case of simultaneous primary hyperparathyroidism with Gitelman’s syndrome resulting in profound electrolyte imbalance.Case: A 48-year old man, referred with hypokalaemia (2.5 mmol/l) presented with a short history of ex...

The medical management of cystic giant prolactinomas with dopamine agonists is controversial as the non-solid components of these aggressive tumours are believed to respond poorly to drug therapy. We present a case of a giant cystic invasive prolactinoma masquerading as a multilobular schwannoma that was successful...
