Ultrasound-guided aspiration and barbotage of acute calcific tendonitis in unusual locations

Acute calcific tendonitis is an excruciatingly painful condition occurring due to the deposition of calcium, that is, calcium hydroxyapatite crystals within the tendons with subsequent rupture into the peritendinous tissues. The most common sites of calcific tendonitis are rotator cuff tendons, followed by the gluteal tendons in the hip. However, calcific tendonitis can occur in any tendons in the body. In this article, we present three unusual sites of acute calcific tendonitis with peritendinous rupture as diagnosed on high-resolution ultrasound (HRUS), along with its ultrasound-guided management. We should be familiar with these unusual sites and their management so that immediate relief and early recovery can be provided to the patient.
