A 59 year-old patient had lumbago and pain in hip joints, knees, and ribs of long duration. Severe hypophosphatemia and high serum ionized calcium were found in spite of normal level of total serum calcium. The serum parathyroid hormone and alkaline phosphatase levels were elevated, and diffuse demineralization of the bones and renal stones were found by x-ray examination. Parathyroid adenoma was diagnosed from the subtraction image of the 99mTc O-4 and 201Tl-Cl2 scintigrams. Osteomalacia was demonstrated by bone biopsy at the right iliac crest. A right lower parathyroid adenoma of 2.0 X 1.8 cm, weighing 4.0 g was removed. The long standing phosphate depletion and hypophosphatemia, due to hyperparathyroidism causing renal damage with nephrocalcinosis and reduced synthesis of active vitamin D, and milk tolerance due to gastroduodenostomy were probably responsible for producing the clinical picture of normocalcemic hyperparathyroidism complicated with osteomalacia.

A 14 year old girl with bilateral genu valgum of 6 years duration was brought for evaluation of primary hyperparathyroidism. She had clinical features of rickets such as frontal bossing, rachitic rosary, lumbar lordosis and fixed adduction deformity of the left leg. She had undergone osteotomy earlier for correction of these deformities without benefit. Laboratory investigations showed hypercalcaemia and hypophosphataemia, with elevated alkaline phosphatase and parathyroid hormone levels. A skeletal survey showed generalized decreased density of bone and brown tumours and, coincidentally, a right renal calculus. A computerized tomography scan of the neck and thallium-technetium subtraction scan delineated an adenoma of the left superior parathyroid gland, which was surgically removed. Parathyroid adenoma manifesting with bone deformities, especially genu valgum, is very rare in children. Early diagnosis and prompt treatment is essential to prevent such deformities.

Parathyroid adenoma can cause primary hyperparathyroidism. Too much parathyroid hormone effects on bone, kidney and small intestine, which can cause parathyroid hormone, serum calcium, urine calcium and serum alkaline phosphatase elevated, while serum phosphate decreased. Clinical manifestations of osteoporosis, kidney stones, high calcium crisis and a serise of performance. There were 2 cases suffered from parathyroid adenoma and parathyroid hyperfunction in our hospital from December 22,2010 to March 11,2011. Surgical operation is the best treatment method.
