MR imaging signs of shoulder adhesive capsulitis: analysis of potential differentials and improved diagnostic criteria.

To evaluate the prevalence of shoulder adhesive capsulitis (AC) signs on MR studies of patients with various common shoulder conditions. MR images of 316 patients were retrospectively evaluated. Patients were divided into three groups: controls (66 patients), clinical AC (63 patients), and study group (187 patients). The final diagnosis of AC was reached clinically. The study group was composed of patients with focal and massive rotator cuff tears, active hydroxyapatite deposition disease, fractures around the shoulder, and post-surgery. The following AC signs were evaluated: inferior glenohumeral ligament (IGHL) thickening; coracohumeral ligament (CHL) thickening; and hyperintensity of the inferior glenohumeral ligament, which was graded in four classes. The IGHL signal intensity was statistically higher in patients with fractures than in controls (P = 0.008). There was no statistically significant difference in IGHL signal between the AC group and patients with massive rotator cuff tears and active hydroxyapatite deposition disease (P > 0.1). IGHL thickness in patients with fractures, massive rotator ruptures, and active hydroxyapatite deposition disease was significantly higher compared to controls (P < 0.02) and significantly lower compared to the AC group (P < 0.0001). Based on these findings, a grading system for fibro-inflammatory capsular changes is proposed. MR AC signs are frequent in patients with shoulder conditions other than AC; however, in these patients, capsular changes are less prominent than in patients with clinical AC.

Hydroxyapatite deposition disease, an overlooked differential diagnosis in the emergency department: a case series and review of literature.

Hydroxyapatite crystal deposition disease (HADD) poses diagnostic challenges in the emergency department (ED) as it may clinically present similarly to infection and other musculoskeletal conditions. Misdiagnosis often leads to unnecessary treatments and resource over-utilization. This review article provides an overview of HADD in seven patients who presented to the ED secondary to an acute presentation of this disease process. HADD is a prevalent pathology, which commonly involves the shoulder, followed by the hip, elbow, wrist, and knee. Predisposing risk factors, such as diabetes and certain genetic factors, have also been identified. Clinical history and imaging, particularly radiographs, play a vital role in diagnosing HADD, with characteristic calcification patterns observed in different stages of the disease. Conservative nonsurgical therapy is the mainstay of treatment, providing effective symptom relief in over 90% of cases. By recognizing HADD as a crucial differential diagnosis for patients with acute or chronic pain, healthcare resource utilization can be optimized, leading to improved patient care in the ED.

Hydroxyapatite Deposition Disease: A Comprehensive Review of Pathogenesis, Radiological Findings, and Treatment Strategies.

Hydroxyapatite deposition disease (HADD) represents a multifaceted condition characterized by the accumulation of hydroxyapatite crystals in soft tissues, leading to subsequent inflammation and discomfort. The intricate etiology of HADD is the subject of this comprehensive review, which encompasses an in-depth analysis of the four proposed pathogenic mechanisms and a deliberation on the predisposing factors that instigate the development of this disease. In order to provide a thorough understanding of the disease's progression, this manuscript delineates the stages of HADD-those preceding calcification, occurring during calcification, and following calcification-in meticulous detail. This chronology forms the basis of a complete portrayal of the evolution of HADD. Moreover, this review encompasses an examination of the radiological findings associated with HADD, furnishing an extensive discourse on imaging characteristics. The potential of HADD to mimic other diseases, thereby posing diagnostic challenges, is also articulated. The discourse continues with an investigation of HADD's differential diagnosis. This section furnishes a robust framework for distinguishing HADD from other conditions based on imaging results. To enrich the understanding of this diagnostic process, case studies illustrating real-world applications are provided. An overview of treatment modalities for HADD, including both conservative and interventional approaches, forms the concluding discussion. The pivotal role of imaging specialists in the diagnosis and management of HADD is emphasized, highlighting their vital contribution to image-guided procedures and disease monitoring.

Hydroxyapatite deposition disease – Think beyond the shoulder!! A case series with unusual sites of involvement

Hydroxyapatite deposition disease (HADD) can affect any location of the body and present with a variety of clinical symptoms. Here, we describe three unusual sites of involvement of HADD around the hip as well as the wrist joint. Magnetic resonance imaging along with computed tomography correlation was performed in these cases, which demonstrated the calcific deposits as well as their associated soft-tissue inflammatory changes. Its imaging findings can look very aggressive and empowering, similar to infection or even malignancy. This makes this entity a great mimicker. Through these cases, we emphasize the need to think about HADD in places other than the classical shoulder girdle and always keep it on the differential list.

Calcific Tendinosis: What the General Radiologist Needs to Know

Hydroxyapatite deposition disease (HADD), or calcific tendinosis, is a common cause of atraumatic pain. Radiologists can be of great diagnostic assistance using imaging and clinical data to decipher HADD from other similar presenting pathologies such as infection, gout, trauma, and tumor. The radiologist should be aware of the various diagnostic imaging pitfalls and mimics of calcific tendinosis so that they may prevent further unnecessary workup and invasive procedures. In addition, radiologists should understand the role of percutaneous image-guided interventions as treatment options for HADD. The radiologist's understanding of the clinical presentation, imaging features, and treatment options of HADD will improve diagnostic accuracy and patient outcomes.

Severe Hydroxyapatite Deposition Disease in Binturongs (Arctictis binturong).

In a collection of 6 young binturongs (Arctictis binturong), 3 presented with anorexia, lethargy, and footpad swelling diagnosed by surgical biopsy as calcinosis circumscripta. Despite supportive care over the next 4 years, affected binturongs had progressive weight loss, hyperphosphatemia, and hyperkalemia and developed large radiodense deposits in tissues adjacent to appendicular joints, thoracolumbar vertebrae, and the sternum. Two binturongs died and necropsies showed severe periarticular mineral deposition with fibrosis and granulomatous inflammation. Additionally, binturongs had mineralization of distal renal tubules, mineralization of the renal interstitium, and marked mineralization of the pulmonary interstitium and peribronchiolar smooth muscle. Foot biopsies from the surviving binturong were evaluated by spectroscopic microanalysis and were positive for hydroxyapatite, Ca10(PO4)6(OH)2. Periarticular and footpad mineralization in these binturongs is consistent with hydroxyapatite deposition disease, which is rarely described in humans and animals as a primary familial condition or a secondary condition often associated with renal injury.

Hydroxyapatite deposition disease of the wrist with intraosseous migration to the lunate bone

Hydroxyapatite deposition disease (HADD) is a mostly uniarticular, self-limiting condition caused by deposition of hydroxyapatite (HA) crystals in tendons or in the peritendinous soft tissues. Commonly, the glenohumeral joint is affected. More rarely, the HA depot can be cause of a carpal tunnel syndrome due to an acute inflammatory reaction and space-occupying soft tissue oedema. We report a case of acute HA depot located at the volar site of the right wrist with affection of the deep flexor tendons and intraosseous migration into the lunate bone in a 50-year-old female. There are two main goals of this case report: First, to remind the diagnosis of HADD as a cause of wrist pain and also of carpal tunnel syndrome, as this entity being often misdiagnosed clinically, and second, to report a rare case of intraosseous migration of HA crystals into the lunate bone.

Mimickers of Hill-Sachs Lesions [Formula: see text

The purpose of this article is to describe the imaging appearance, etiology, clinical features, and treatment of rare presentations of common bone and joint diseases known to mimic Hill-Sachs lesions. Knowledge of uncommonly encountered manifestations of ankylosing spondylitis, rheumatoid arthritis, septic joint, hyperparathyroidism, hydroxyapatite deposition disease, malignant bone tumors, and benign bone cysts which mimic traumatic Hill-Sachs lesions is important for radiologists to guide the clinical care of patients who present with shoulder symptoms.

Calcium hydroxyapatite deposition disease: Imaging features and presentations mimicking other pathologies

ObjectiveCalcium hydroxyapatite depositional disease (HADD) is usually asymptomatic and self-limiting; however, when there is an associated inflammatory process or HADD occurs in an unusual location, it may mimic trauma, infection, or neoplasm. The purpose of this article is to review the imaging features of HADD and how to distinguish it from more worrisome entities that can have similar appearances. ConclusionAn understanding of the presentations of HADD is important to allow early and confident diagnosis. In particular, familiarity with presentations that resemble more ominous pathologies is essential to avoid costly and time-consuming workup or intervention.

Hydroxyapatite Deposition Disease- Spontaneous Resolution of Significant Post Treatment Deposit

Hydroxyapatite Deposition Disease- Spontaneous Resolution of Significant Post Treatment Deposit

MR Imaging and US of the Wrist Tendons.

The tendons of the wrist are commonly symptomatic. They can be injured, infected, or inflamed. Magnetic resonance imaging and ultrasonography are useful tools for evaluating the wrist. Pathologic conditions of the wrist tendons include de Quervain tenosynovitis, extensor carpi ulnaris tendinopathy, rheumatoid tenosynovitis, infectious synovitis, tendon tears, hydroxyapatite deposition disease, intersection syndrome, tenosynovial giant cell tumor, and fibroma of the tendon sheath. In this article, we review the normal appearance of the wrist tendons, discuss relevant anatomy, and give an overview of common pathologic conditions affecting the wrist tendons. Online supplemental material is available for this article. ©RSNA, 2016.

Hydroxyapatite deposition disease around the hip: outcomes of CT-guided treatment

Hydroxyapatite deposition disease (HADD) around the hip joint is a self-limiting condition usually treated conservatively. The aim of the present study is to directly compare the outcomes of CT-guided and conservative treatments in cases of refractory hip HADD. Two groups of patients with refractory hip HADD were prospectively constructed from a pool of 484 patients referred for greater trochanter pain syndrome, based on the presence of calcifications around the hip and the failure of conservative treatment. Study group included 22 hips, which underwent CT-guided barbotage and steroid injection treatment, whereas control group consisted of 28 hips that were treated conservatively. Evaluation of the outcome of both groups was performed over a one-year follow-up period with the use of a score measuring clinical improvement in terms of pain and functional impairment. Three weeks after the initiation of treatment, study group exhibited significantly higher scores compared with the control group (P < 0.001). Improvement scores of the control group were similar to the study group after three months of treatment (P > 0.1). CT-guided treatment provides relief of debilitating symptoms in the acute phase.

A Case of Bilateral Acute Calcific Tendinitis of the Gluteus Medius, Treated by Ultrasound-guided Needle Lavage and Corticosteroid Injection.

Calcium hydroxyapatite deposition disease is a common pathology, most frequently located in the rotator cuff tendons of the shoulder, for which different therapeutic approaches are used. Ultrasound guided needle lavage and injection of anesthetic/corticosteroid is a well-known and extensively described treatment for calcific tendinits of the rotator cuff. We present a case of bilateral calcific tendinitis of the gluteus medius tendon, both sides successfully treated using ultrasound guided needle lavage of the deposits and injection of an anesthetic and corticosteroid. We propose to not only use this approach for rotator cuff tendons, but also for calcific tendinitis at other locations.

The role of radiology in the evolution of the understanding of articular disease.

Both the clinical practice of radiology and the journal Radiology have had an enormous effect on our understanding of articular disease. Early descriptions of osteoarthritis (OA) appeared in Radiology. More recently, advanced physiologic magnetic resonance (MR) techniques have furthered our understanding of the early prestructural changes in patients with OA. Sodium imaging, delayed gadolinium-enhanced MR imaging of cartilage, and spin-lattice relaxation in the rotating frame (or T1ρ) sequences have advanced understanding of the pathophysiology and pathoanatomy of OA. Many pioneering articles on rheumatoid arthritis (RA) also have been published in Radiology. In the intervening decades, our understanding of the natural history of RA has been altered by these articles. Many of the first descriptions of crystalline arthropathies, including gout, calcium pyrophosphate deposition, and hydroxyapatite deposition disease, appeared in Radiology.

Humeral Lateral Epicondylitis Complicated by Hydroxyapatite Dihydrite Deposition Disease: A Case Report

ObjectiveThe aim of this case report is to differentiate the recovery timeline expected for patients with simple lateral epicondylitis from an abnormal recovery period, in which case an underlying condition should be suspected. Clinical featuresA 49-year-old woman presented to a chiropractic clinic with posterolateral right elbow pain. The history included chronic recurrent lateral elbow pain, followed by a traumatic event leading to sustained pain and disability. Intervention and outcomesFollowing a trial of conservative therapy including activity restrictions, soft tissue therapy, joint mobilizations, and therapeutic ultrasonography that led to no significant improvement, the patient was referred for diagnostic imaging that revealed hydroxyapatite dihydrite deposition disease. ConclusionThis report describes a case for which lateral epicondylitis symptoms failed to resolve because of an underlying condition (hydroxyapatite dihydrite deposition disease). This case emphasizes that primary care practitioners treating lateral epicondylitis should consider referral for further investigations when positive results are not achieved.

An Unusual Cause of Neck Pain: Acute Calcific Tendinitis of the Longus Colli

Calcific tendinitis of the longus colli muscle is a rare, but probably underrecognized form of calcium hydroxyapatite deposition disease. Patients present with severe neck pain, neck stiffness, odynophagia and mildly elevated inflammatory markers. This self-limited condition can easily mimic other serious diseases, such as retropharyngeal abscess, meningitis, infectious spondylodiscitis or cervical fracture. It is therefore important to promptly recognize this benign disease to avoid unnecessary and invasive tests and procedures. We present the case of a 34-year-old woman who developed acute calcific tendinitis of the longus colli following a tick bite to the neck. J Med Cases. 2014;5(3):171-173 doi: http://dx.doi.org/10.14740/jmc1600w

Tumoral Calcinosis Form of Hydroxyapatite Deposition Disease in Related Red-Bellied Short-Necked Turtles, Emydura subglobosa

Ten of 12 red-bellied short-necked turtles from a single clutch presented at 9 months of age with multiple white to tan nodules on their feet. Histologically, the nodules were composed of large periarticular deposits of mineralized crystalline material that extended into the joint spaces of interphalangeal joints and was surrounded by granulomatous inflammation and fibrosis. Crystallographic analysis determined the material to be apatite (calcium phosphate hydroxide) consistent with the tumoral calcinosis form of hydroxyapatite deposition disease (HADD). HADD has previously been described in aquatic turtles and rarely lizards and must be differentiated from gout in reptiles. A cause for the tumoral calcinosis lesions in these turtles could not be determined; however, based on previous reports in this species, a species-specific predilection, in conjunction with unknown environmental factors, is suspected. The use of the terms HADD, pseudogout (calcium pyrophosphate crystal deposition disease), and calcinosis circumscripta has been inconsistent, creating confusion in the literature.
