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.

Calcific Deposits

Abstract 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.

Retropharyngeal calcific tendonitis (RCT) is an aseptic inflammatory process of the superior oblique tendons of the longus colli muscle caused by the deposition of calcium hydroxyapatite crystals. We reported a 23-year-old woman who presented with a sudden onset of neck pain with odynophagia after waking up from sleep. Physical examination showed paracervical point tenderness with limited neck movement in all directions. Prior to surgery, further imaging was requested to aid in diagnosis, which in turn revealed RCT. It is important to be aware that RCT presentation may mimic other severe conditions such as retropharyngeal space abscess or meningitis.

The benefit of adding sonography to the examination of patients suffering from shoulder pain, was examined in this retrospective evaluation. A patient suffering from shoulder pain consults generally his family physician, who sends his patient first to a radiography and not to sonography. In 75% of the patients examined by sonography, shoulder lesions were diagnosed, demonstrated in only 33% of radiographs. Most patients had more than one lesion: 38% had partial or full-thickness tears of the supraspinatus tendon, about one third bicipital tendonitis, 18% irregularities of the humeral greater tuberosity, 10% subdeltoid bursitis and about 10% calcified tendonitis. In about a quarter of the patients, no pathology was found. Many patients had more than one lesion. In conclusion, clinicians encountering shoulder pain should not be content with conventional radiography and are encouraged to make sonographic examinations part of the early diagnostic protocol.

Milwaukee shoulder syndrome (MSS) is a rare destructive, calcium phosphate crystalline arthropathy. It encompasses an effusion that is noninflammatory with numerous aggregates of calcium hydroxyapatite crystals in the synovial fluid, associated with rotator cuff defects. We describe a patient that presented with recurrent shoulder pain and swelling with characteristic radiographic changes and MSS was confirmed on aspiration of the synovial fluid.

Benign Process

Limited cases of rotator cuff tears with acromioclavicular (AC) degeneration in association with cystic swelling or ganglion cyst have been described till date. The “geyser radiographic sign” was originally described by Craig in 1984. Its significance was to document a tear in the articular capsule of the AC joint in the setting of a chronic full-thickness tear of the rotator cuff, which gave the appearance of a geyser arising from the subacromial bursa as radiographic contrast tracked through the AC joint to project superiorly from the shoulder. An 82-year-old male presented with pain on rest in the left shoulder and with difficulty in overhead abduction from last few months. MRI showed near complete full-thickness tear of supraspinatus tendon with retraction of the tendon and reduced bulk of the supraspinatus muscle with associated superior subluxation of humerus with AC arthropathic changes causing ganglion cyst and incidental finding of superior labrum anterior and posterior tear. AC cysts are further divided into Type 1 and Type 2. Repeated aspirations of these masses are not advised, as they often recur and repeated attempts at aspiration may lead to formation of a draining fistula. MRI geyser sign is highly suggestive of a benign process, which suggests underlying rotator cuff pathology.

Pictorial Essay

Abstract More than half of patients over 50 years of age have had at least one focal renal lesion detected as an incidental finding during an ultrasound, computed tomography, or magnetic resonance imaging examination. Although the majority of such lesions can be easily detected and correctly characterized, misdiagnoses may occur and are often related to methodological limitations, inappropriate imaging protocols, or misinterpretation. This pictorial essay provides recommendations on how to recognize benign and malignant renal processes that can be potentially missed or mischaracterized in imaging studies.
