On ultrasound (MSKUS) scans, calcific deposits of calcific tendinopathy most commonly appear hyperechoic. Three types have been described, based on the percentage of calcium in the deposits:
•Type 1 calcifications are rich in calcium and correspond to the formative and resting phases;
MSKUS shows them as hyperechoic structures with well-defined acoustic shadowing.
•Type 2 calcifications are hyperechoic but show a faint acoustic shadow.
•No acoustic shadow is seen in Type 3 calcifications.
Types 2 and 3 generally correspond to the resorptive phase in which the calcium deposit appears poorly defined. Type 3 calcifications may be isoechoic to tendons, an appearance that may be misleading for novice sonographers and lead to under detection of the calcifications.
