Cause in Alphabetical Order

Differential Diagnosis

In alphabetical order. [1] [2]

osteolysis must be differentiated from other causes of hypercalcaemia

Differential diagnosis of hyperparathyroidism on the basis of hypercalcemia
Disorder Mechanism of hypercalcemia Clinical features Laboratory findings Imaging & diagnostic modalities
PTH Calcium Phosphate Other findings
Hyperparathyroidism Primary hyperparathyroidism Increase in secretion of parathyroid hormone (PTH) from a primary process in parathyroid gland. Parathyroid hormone causes increase in serum calcium.
  • Usually asymptomatic
  • Hypercalcemia detected on routine biochemical panel
↓/Normal Normal/↑ calcitriol Findings of bone resorption:

Preoperative localization of hyperfunctioning parathyroid gland:

Predicting post-operative success:

Secondary hyperparathyroidism Increase in secretion of parathyroid hormone (PTH) from a secondary process. Parathyroid hormone causes increase in serum calcium after long periods. ↓/Normal --
Tertiary hyperparathyroidism Continuous elevation of parathyroid hormone (PTH) even after successful treatment of the secondary cause of elevated parathyroid hormone. Parathyroid hormone causes increase in serum calcium. --
Familial hypocalciuric hypercalcemia This is a genetic disorder caused my mutation in calcium-sensing receptor gene.
  • A benign condition
  • Does not require treatment
Normal/↑ Normal/↑ -- --
  • Urinary calcium/creatinine clearance ratio
Malignancy[3] Humoral hypercalcemia of malignancy[4][5][6] Tumor cells secretes parathyroid hormone-related protein (PTHrP) which has similar action as parathyroid hormone. -- ↓/Normal PTHrP

Normal/↑ calcitriol

Osteolytic tumors Multiple myeloma produces osteolysis of bones causing hypercalcemia. Osteolytic metasteses can cause bone resorption causing hypercalcemia. -- --
Production of calcitirol Some tumors has ectopic activity of 1-alpha-hydroxylase leading to increased production of calcitriol. Calcitriol is active form of vitamin D and causes hypercalcemia. -- -- Calcitriol
Ectopic parathyroid hormone[7] Some tumors leads to ectopic production of parathyroid hormone. ↓/Normal Normal/↑ calcitriol
Medication induced Lithium[8] Lithium lowers urinary calcium and causes hypercalcemia. Lithium has been reported to cause an increase in parathyroid hormone and enlargement if parathyroid gland after weeks to months of therapy. -- --
Thiazide diuretics Thiazide diuretics lowers urinary calcium excretion and causes hypercalcemia. -- -- -- --
Nutritional Milk-alkali syndrome Hypercalcemia is be caused by high intake of calcium carbonate. -- -- --
Vitamin D toxicity Excess vitamin D causes increased absorption of calcium from intestine causing hypercalcemia. -- -- Vitamin D (calcidiol and/or calcitriol) --
Granulomatous disease Sarcoidosis[11] Hypercalcemia is causes by endogeous production of calcitriol by disease-activated macrophages. -- -- Calcitriol
