Calcifying bursitis is a special type of an affection of the bursa. It differs from the previous representatives of the presence of calcification in the X-ray picture. But a calcification of the tendon looks equally. The ultrasound examination can differ if there is the bursa affected with the calcification or the tendon. With regarding to a frequent finding of clinical mute calcifications, it is possible to verify during the dynamic ultrasound examination if the calcification is a causative agent of the patient's problems. If we can judge according to our experience, then most of the X-ray contrasting calcifications with a clear demarcation are not clinically important. Only X-ray calcifications, wreathing and little visible, evoked by hydroxyapatitic bursitis, which were not also important according to the roentgenologists, are clinically important. A localization of the calcification in this case corresponded to the place where the patient felt the biggest pains. In most cases, except mentioned hydroxyapatitic bursitis, it was not so.
