At the site of swelling and pain pointed by the patient, there is an amorphous calcific deposit in the soft tissue involving the dorsum of the wrist. The calcification is located between tendons of 2nd extensor compartment and superficial to the carpal bone. There is a local hypervascularity. The extensor compartment tendons show normal echo pattern without tenosynovitis. The adjacent bone cortex does not show erosion.
The case shows the typical history and ultrasound findings of acute calcific periarthritis.
