“…In Pereira's study, follow-up information was available in five subjects: two of which underwent arthroscopic surgery after the failure of conservative therapy [9]. Vinanti et al reported to have treated this disease surgically in one patient [11]; Wang et al treated one patient with an intramuscular calcification of the subscapularis through ultrasound guided needling [12]. In the case report presented by Mileto et al the patient was treated conservatively [10].…”

Calcific tendinopathy of the shoulder is a common condition caused by calcium hydroxyapatite crystals, affecting the tendons of the rotator cuff. Among uncommon complication, one is the migration of the calcium in the subacromion-subdeltoid bursa. More rare is the intraosseous migration. We present four cases of an even more rare condition, not well described in literature yet, the intramuscular migration of calcium.Keywords Calcific tendinopathy Á Intramuscular migration Á Shoulder pain Á Ultrasound Á Calcium hydroxyapatite crystal deposition disease Á Rotator cuff Riassunto La tendinopatia calcifica della spalla è una condizione comune causata da cristalli di idrossiapatite di calcio, che colpisce i tendini della cuffia dei rotatori.

“…Rotator Cuff is the most affected site, in particular the supraspinatus tendon, followed by the infraspinatus, the subscapularis and the teres minor [11]. Despite its high prevalence in the rotator cuff, any tendon may be affected, with similar pathogenetic mechanisms and appearance.…”

Imaging of calcific tendinopathy in atypical sites by ultrasound and conventional radiography: A pictorial essay

Calcific tendinopathy (CT) is a very common condition caused by the deposition of calcium hydroxyapatite crystals in tendons and it can be an incidental finding or associated with severe pain. CT can be easily detected by first level exams such as traditional radiography and ultrasound (US), which provide information on the site, extent and composition of the calcific formation. Classically, the most affected site is represented by the rotator cuff tendons, in particular the supraspinatus tendon. In this pictorial essay we illustrate various unusual localizations of CT detected by US and plain radiography, in order to provide an overview with the aim of preventing diagnostic delays and consequently CT complications.

“…It has been described from case series and case reports as calcific opacities at plain radiographs or as inhomogeneous hyperechoic mass at US located along the anterior aspect of the proximal third of the biceps brachii muscle [ 66 , 67 ]. Calcifications at the origin of long head of the biceps, such as biceps anchor or biceps labral complex, have been less described in literature and generally present an ovoid shape, with their position close to the upper glenoid being unchanged during external or internal rotation of the humerus [ 66 , 68 , 69 ]. However, it is unlikely these represent real calcific tendinopathy but rather calcific apposition over degenerated tendons.…”

Imaging of calcific tendinopathy around the shoulder: usual and unusual presentations and common pitfalls

et al. 2020

Rotator cuff calcific tendinopathy (RCCT) is a very common condition, characterized by calcium deposition over fibrocartilaginous metaplasia of tenocytes, mainly occurring in the supraspinatus tendon. RCCT has a typical imaging presentation: in most cases, calcific deposits appear as a dense opacity around the humeral head on conventional radiography, as hyperechoic foci with or without acoustic shadow at ultrasound and as a signal void at magnetic resonance imaging. However, radiologists have to keep in mind the possible unusual presentations of RCCT and the key imaging features to correctly differentiate RCCT from other RC conditions, such as calcific enthesopathy or RC tears. Other presentations of RCCT to be considered are intrabursal, intraosseous, and intramuscular migration of calcific deposits that may mimic infectious processes or malignancies. While intrabursal and intraosseous migration are quite common, intramuscular migration is an unusual evolution of RCCT. It is important also to know atypical regions affected by calcific tendinopathy as biceps brachii, pectoralis major, and deltoid tendons. Unusual presentations of RCCT may lead to diagnostic challenge and mistakes. The aim of this review is to illustrate the usual and unusual imaging findings of RCCT that radiologists should know to reach the correct diagnosis and to exclude other entities with the purpose of preventing further unnecessary imaging examinations or interventional procedures.
