Other studies, including brain CT scan and ophthalmologic examination for cataracts, revealed no abnormal metastatic calcifications. The results of other paraclinical tests-including liver and renal function tests, fasting blood glucose, calcium, phosphorus, prothrombin and partial thromboplastin times, thyroid function, alfa feto protein, beta-HCG level, tuberculin skin test, serology for brucella infection, hepatitis B and C, anti-cytomegalovirus IgM and IgG, human immunodeficiency virus, serology for toxoplasma infection, and workup for hydatid cyst and amebic and fungal infections, revealed no abnormalities.
Diffuse metastatic calcifications caused by secondary hyperparathyroidism.
* Metastatic calcification is caused by a disturbance in calcium metabolism.
Beerens AJ and stel HV5, in 1999 reported a patient with end stage renal disease who had a subacute swelling of the membranous nasal septum, caused by the calcium phosphate depositions, fallowing these there have been many reports of metastatic calcification in the septum on the true vocal cords in patients with end stage renal disease.
Metastatic calcification usually results from a deposition of calcified products in otherwise normal tissues as a result of hyperphosphataemia with or without hypercalcaemia.
In addition the use of vitamin D analogs to decrease PTH may increase calcium levels and may indirectly perpetuate metastatic calcifications. In this group of patients, one third of the population was using calcium acetate binders and one half, vitamin D analogs.
