Tendinitis calcificante del musculo largo del cuello: presentación de un caso clínico / Calcific tendinitis of the longus colli muscle: a case report / Tendinite calcificante do músculo longo do pescoço: apresentação de um caso clínico

La tendinitis calcificante del músculo largo del cuello es una patología subdiagnsoticada, de baja frecuencia, autolimitada. Se presenta clínicamente como una de las causas de odinofagia en la consulta médica. Se produce debido al depósito de cristales de hidroxiapatita en espacio retrofaríngeo, desencadenándose una respuesta inflamatoria local. En la TMLC el principal diagnóstico diferencial es el absceso retrofaríngeo, ya que puede presentarse clínicamente con odinofagia, disfagia , disminución de la movilidad del cuello y cervicalgia. En nuestro trabajo se analiza un caso clínico sobre dicha patología, en un hombre de 45 años; realizando un análisis de la sintomatología, diagnóstico y tratamiento de esta entidad.

Calcific tendinitis of the long neck muscle is an underdiagnosed, low frequency, self-limited pathology. It is clinically presented as one of the causes of odynophagia in the medical consultation. It occurs due to the deposit of hydroxyapatite crystals in the retropharyngeal space, triggering a local inflammatory response. On This patholgy, the main differential diagnosis is retropharyngeal abscess, since it can present clinically with odynophagia, dysphagia, decreased mobility of the neck, and neck pain. In our work, a clinical case of this pathology is analyzed, in a 45-year-old man; performing an analysis of the symptoms, diagnosis and treatment of this entity.

Tendinopatía cálcica: etiopatogenia y evaluación por imágenes / Calcific tendinitis: aetiopathogenesis and imaging evaluation

Resumen: La tendinopatía cálcica es causada por el depósito patológico de cristales de hidroxiapatita de calcio en los tendones y es una causa común de dolor en las articulaciones. Afecta más frecuentemente al hombro y la cadera, con hallazgos característicos en imágenes; sin embargo, cualquier tendón puede estar involucrado. Ocasionalmente, la tendinopatía cálcica puede simular patología agresiva, como infección o neoplasia, especialmente en RM. Fisiotpatológicamente, las calcificaciones provendrían de una diferenciación anormal de las células madre del tendón, que comienzan a producir calcio, aunque todavía no es del todo claro. Los radiólogos deben estar familiarizados con los hallazgos de las imágenes para distinguir la tendinopatía cálcica de procesos más agresivos. La aspiración y lavado guiado bajo ecografía es una técnica útil realizada por el radiólogo para el tratamiento de casos sintomáticos. La familiaridad con estos procedimientos y su apariencia en imágenes es un aspecto importante en el manejo de esta enfermedad. El propósito de esta revisión es analizar la etiopatogenia de la tendinopatía cálcica, la evaluación con imágenes en los sitios de presentación más comunes y también en los menos frecuentes, así como el papel que desempeña la ecografía en el tratamiento de la patología.

Abstract: Calcific tendinitis is caused by abnormal deposition of calcium hydroxyapatite crystals in tendons and is a common cause of joint pain. The disease typically affects the shoulder and hip, with characteristic imaging findings; however, any tendon can be involved. Occasionally, calcific tendinitis can mimic aggressive disorders, such as infection and neoplasm, especially on MRI. Apparently, the calcifications come from an abnormal differentiation of the tendon stem cells, which begin to produce calcium. Radiologists should be familiar with the imaging findings to distinguish calcific tendinitis from more aggressive processes. Image-guided percutaneous needle aspiration is a useful technique performed by the radiologist for the treatment of symptomatic cases. Being familiar with these processes and their imaging appearance is an important aspect in the management of this common disease. The purpose of this review is to analyze the pathogenesis of calcium tendinopathy, the evaluation of images in both the most common and less frequent presentation sites, as well as the role played by ultrasound in the treatment of pathology.

Tendinitis calcificante del longísimo del cuello / Acute calcific tendinitis of the longus colli muscles

RESUMEN La tendinitis calcificante prevertebral es una patología benigna y poco frecuente, con una incidencia anual de 0,5 casos por cada 100.000 habitantes. Se presenta un caso de una paciente de 52 años que consultó por cervicalgia, odinofagia y disfonía de 5 días de evolución. Tras una exploración otorrinolaringológica completa se sospechó ocupación del espacio retrofaríngeo, confirmada con pruebas de imagen. Ante estos hallazgos y con la sospecha de absceso retrofaríngeo, se decidió ingreso hospitalario para tratamiento intravenoso. Por discordancia entre la clínica, la TC y los hallazgos analíticos, se solicitó RM cervical, cuya imagen hizo sospechar una tendinitis aguda calcificante del longísimo del cuello. En este trabajo se ha realizado una revisión de la sintomatología, el diagnóstico y el tratamiento de esta entidad. Consideramos importante sospecharla dentro del diagnóstico diferencial de la ocupación del espacio retrofaríngeo para evitar realizar procedimientos innecesarios.

ABSTRACT Prevertebral calcific tendinitis is a benign and infrequent pathology, with an annual incidence of 0.5 cases per 100,000 habitants. We report the case of a 52-year-old woman that presented with a 5-day history of cervicalgia, odynophagia and dysphonia. Otolaryngological examination and radiological images showed occupation of the retropharyngeal space. The patient was admitted to the hospital for intravenous treatment. A cervical MRI was requested, suggesting an acute calcific tendinitis of the longus colli muscles. The authors provide a discussion of the clinical findings, diagnosis and treatment of this condition. We consider it to be an important differential diagnosis of a retropharyngeal space occupation, in order to avoid unnecessary procedures.

Functional Recovery of the Shoulder after Arthroscopic Treatment for Chronic Calcific Tendinitis

BACKGROUND: We investigated the resolution of pain and functional recovery of shoulder after arthroscopic removal of calcific deposits in patients with chronic calcific tendinitis. METHODS: We enrolled 39 patients who were treated arthroscopically for chronic calcific tendinitis that had been non-responsive to at least 6 months of conservative treatment. We evaluated clinical outcome in terms of the American Shoulder Elbow Surgeons (ASES), the Constant score, the visual analogue score (VAS) for pain. We used plain radiography to measure the size of the calcific deposits. We also analyzed the clinical outcomes in terms of whether or not a cuff repair was performed or the degree of removal of calcific deposits. RESULTS: We found that complete resolution of pain took on average 5.7 months after the arthroscopic treatment. The ASES and the Constant score significantly improved from the 3-month follow-up, however it took 6 months until the scores reached on average 80 points or above. We found that these clinical outcomes at the final follow-up did not significantly differ by whether or not cuff repair was performed. Similarly, we found that the clinical outcomes did not significantly differ by the degree of calcium removal. CONCLUSIONS: We found that arthroscopic removal of calcification leads to improved clinical outcomes in patients with chronic calcific tendinitis. However, our findings show it takes at least 6 months for the clinical improvement to become statistically significant. We also found that concomitant cuff repairs or the degree of removal of calcification does not affect the clinical outcome of the arthroscopic treatment.

Clinical and Imaging Features of Longus Colli Calcific Tendinitis: An Analysis of Ten Cases

BACKGROUND: Longus colli calcific tendinitis (LCCT) exhibits characteristic clinical features; thus, misidentification can be avoided once it is learned. There is a lack of reports on this disease. In this study, we analyzed the imaging and clinical features of LCCT in 10 patients. METHODS: We retrospectively reviewed the radiolographic findings, laboratory data and clinical features of 10 patients diagnosed with LCCT between January 2015 and June 2017. All patients were treated with medical treatment consisting of intravenous methylprednisolone 125 mg twice and oral nonsteroidal anti-inflammatory drug administration. RESULTS: On clinical findings, all 10 patients complained of severe posterior neck pain and cervical motion limitation. Odynophagia was present in nine patients. The mean time from symptom onset to hospital visit was 2.9 days. The mean time to symptom relief was 4.6 days. Of the 10 patients, three patients were admitted through the emergency room. There were five patients in the medical records who were transferred from another hospital. On the laboratory data, the mean value of C-reactive protein and erythrocyte sedimentation rate were 2.08 mg/dL (reference range, < 0.30 mg/dL) and 36.9 mm/hr (reference range, < 20 mm/hr), respectively. Leukocytosis was found in only two patients and fever was not present all patients. On radiographic findings, calcification was present on computed tomography images of all patients. The calcification was located at the lower part of the C1 arch, except for one case where calcification occurred in the anterolateral aspect of the C4–5 disc space. The mean value of the retropharyngeal space was 7.2 mm. CONCLUSIONS: LCCT, a rare disease, has characteristic radiographic findings and clinical features. Understanding such characteristics of this disease can prevent unnecessary testing and misdiagnosis.

Tendinitis cálcica del manguito rotador y su lavado por ultrasonido / Calcific tendinitis of the rotator cuff and its lavage using ultrasound

Purpose: The objective of this study is to describe the technique of lavage and aspiration of calcifications under ultrasound in patients affected by this entity and to evaluate their results in the short term. Experimental design: Retrospective, descriptive study, with approval from the Ethics Committee of the Institution. Material and Methods: We performed a retrospective search of patients who underwent lavage as well as shoulder aspiration under ultrasound for calcific tendinitis at the Clínica Alemana in Santiago. 94 patients were identified between the years 2011 and 2015, of which 23 were excluded due to incomplete data. The electronic clinical record was reviewed and the data was recorded in RedCap v6 and statistical analyzes were performed using StataSE v12. Results: The sample consisted of 71 patients, the median age being 50.1 years (IQR: 41.6-57.7) and 45.1% were women. 70.4% affected the right shoulder. The mean evolution of the symptoms was 5 months (IQR: 2-24 months). 22.5% received one or more previous infiltrations and 47.9% attended kinesiotherapy. The calcifications corresponded mainly to type 1 according to the Gartner and Heyer classification (73.3%), with a median size of 14 mm on their major axis (IQR: 10-18 mm). They affected one tendon in 74.7%, two tendons in 18.3% and three tendons in 7.0%, the supraspinatus being the tendon most frequently affected (90.1%). 85.9% presented complete or significant improvement of the symptoms, only 8.5% requiring surgical resolution with arthroscopy. The final improvement had no significant association with the Gartner and Heyer type (p= 0.3), size (p= 0.16), or with the evolution time of the symptoms (p= 0.7). Conclusions: Patients with calcific tendinitis who underwent lavage and aspiration under ultrasound had, in most cases, a significant or total resolution of the symptoms at two months follow-up, with only a minor percentage requiring arthroscopy. It was not possible to identify predictors of poor evolution for this procedure. Further studies are needed to determine its advantages over medical treatment.

Propósito: El objetivo de este estudio es describir la técnica de lavado y aspirado de calcificaciones bajo ultrasonido en pacientes afectados por esta entidad y evaluar sus resultados a corto plazo. Diseño experimental: Estudio retrospectivo, descriptivo, con aprobación del Comité de Ética de la Institución. Material y Métodos: Se realizó una búsqueda retrospectiva de los pacientes sometidos a lavado más aspirado de hombro bajo ultrasonido por tendinitis cálcica en Clínica Alemana de Santiago. Se identificaron 94 pacientes entre los años 2011 y 2015, de los cuales 23 fueron excluidos por presentar datos incompletos. Se revisó la ficha clínica electrónica y los datos fueron registrados en RedCap v6 y los análisis estadísticos se realizaron usando StataSE v12. Resultados: La muestra se compuso por 71 pacientes, siendo la mediana de edad de 50,1 años (Rango Intercuartil, RIC: 41,6-57,7) y un 45,1% correspondió a mujeres. El 70,4% afectó el hombro derecho. La evolución media de los síntomas fue de 5 meses (RIC: 2-24 meses). Un 22,5% recibió una o más infiltraciones previas y 47,9% asistió a kinesio-terapia. Las calcificaciones correspondieron principalmente al tipo 1 según la clasificación de Gartner y Heyer (73,3%), con una mediana de tamaño de 14 mm en su eje mayor (RIC: 10-18 mm). Afectaron un tendón en 74,7%, dos tendones en 18,3% y tres tendones en 7,0%, siendo el tendón más frecuentemente afectado el supraespinoso (90,1%). El 85,9% presentó mejoría completa o significativa de los síntomas, requiriendo resolución quirúrgica con artroscopía tan sólo un 8,5%. La mejoría final no tuvo asociación significativa con el tipo de Gartner y Heyer (p= 0,3), tamaño (p= 0,16), ni con el tiempo de evolución de los síntomas (p= 0,7). Conclusiones: Los pacientes con tendinitis cálcica que son sometidos a lavado y aspirado bajo ultrasonido tuvieron en su mayoría una resolución significativa o total de los síntomas a los dos meses de seguimiento, requiriendo artroscopia en un porcentaje menor. No se lograron identificar factores predictores de mala evolución de este procedimiento. Se requieren de más estudios para determinar sus ventajas por sobre el tratamiento médico.

Needling Procedures for Calcific Tendinitis Performed by Orthopedic Surgeons

BACKGROUND: Common and effective treatments for calcific tendinitis involve needling procedures. However, it has been widespread practice to refer patients with calcific tendinitis, which is a predominantly orthopedic condition, to radiology department. The purpose of this study was to compare clinical and radiological outcomes after ultrasound-guided needling for calcific tendinitis between the orthopedics and radiology department. METHODS: Seventy-seven shoulders (Group 1) and 38 shoulders (Group 2) treated in the radiology and orthopedic department, respectively. A fellowship-trained orthopedic surgeon and a musculoskeletal radiologist each performed the procedure of ultrasound-guided needle decompression with subacromial steroid injection. Clinical outcomes was evaluated using the visual analogue scale for pain (pVAS) and the American Shoulder and Elbow Surgeons (ASES) shoulder score before treatment and at each follow-up. The pre- and post-needling size and shape of the calcific deposits were compared between the two groups. RESULTS: We analyzed a total of 56 shoulders for Group 1 and 32 shoulders for Group 2. The mean age and sex ratio of the patients no significantly different. We found that the mean decrease in the diameter of calcification between pre- and post-needling was 9.0 mm for Group 1 and 13.1 mm for Group 2; the difference was significantly larger in Group 2 than in Group 1. Both groups showed improved pVAS and ASES scores after needling but the extent of these improvements did not differ with the type of operator. CONCLUSIONS: Needling decompression performed by orthopedic surgeons could a viable option for the treatment of calcific tendinitis.

Isolated Ruptures of the Infraspinatus: Clinical Characteristics and Outcomes

BACKGROUND: Isolated infraspinatus tear is very rare and clinical features are not as well known, therefore the purpose of this study was to evaluate clinical characteristics and outcomes of isolated infraspinatus tear that authors experienced. METHODS: Authors reviewed 288 cases of full-thickness rotator cuff tear involving infraspinatus between 2010 and 2015, and retrospectively analyzed six cases of isolated infraspinatus tear. Perioperative clinical characteristics, postoperative functional outcomes of 6 months were investigated. Functional evaluation included visual analogue scale (VAS), range of motions, American Shoulder and Elbow Surgeons (ASES) score, and Constant score. RESULTS: Calcific tendinitis was accompanied in 4 cases (66.7%). Three of them received steroid injection or aspiration or extracorporeal shockwave therapy. Mean preoperative pain VAS was 7.1 (range, 5–9), and mean postoperative pain VAS at 6 months later was 1.6 (range, 0–5). Preoperative muscle strength by isokinetic muscle performance test showed 52% deficit of abduction and 37.6% deficit of external rotation. All 6 patients had arthroscopic repair of the infraspinatus tendon. All the patients at the 6 months follow-up exhibited clinical improvement in the Constant score (67.8 [range, 45–77] to 89.3 [range, 81–100], p=0.029), and ASES score (52.3 [range, 30–77] to 90.0 [range, 80–100], p=0.002). There was no healing failure on imaging. CONCLUSIONS: Isolated infraspinatus tendon tear was frequently accompanied by calcific tendinitis, but pathophysiologic relationship should need more study. To rule out neurogenic etiology, magnetic resonance imaging and electromyography would be helpful. Arthroscopic infraspinatus tendon repair and supraspinatus debridement showed relatively good result in painful shoulder.

Isolated Infraspinatus Tear and Suprascapular Nerve Neuropathy after Barbotage and Steroid Injection of Calcific Tendinitis / 대한스포츠의학회지

Isolated rupture of infraspinatus after barbotage for calcific tendinitis has not been reported in the literature. We report on a case of isolated infraspinatus rupture and suprascapular nerve neuropathy after steroid injection and barbotage of calcific tendinitis in rotator cuff. At 6-month follow-up after surgery, satisfactory clinical and radiological outcomes were observed with daily activity level. The author reports this case and review the literature.

Misconceived Retropharyngeal Calcific Tendinitis during Management of Myofascial Neck Pain Syndrome

Differential diagnosis of posterior neck pain is very challenging based on symptoms and physical examination only. Retropharyngeal calcific tendinitis is a rare and frequently misdiagnosed entity in various causes of neck pain. It results from calcium hydroxyapatite deposition in the longus colli muscle which is characterized by severe neck pain, painful restriction of neck movement, dysphagia, and odynophagia. We herein report a case of a patient with acute retropharyngeal calcific tendinitis, who complained of posterior neck pain, initially diagnosed and treated as a myofascial neck pain syndrome.

Atypically Large Calcific Tendinitis of the Shoulder: A Case Report

Calcific tendinitis of the shoulder joint is common disease causing acute pain, mainly involving the supraspinatus or infraspinatus muscle, and less frequently the teres minor or subscapularis muscle. This study reports on the satisfactory arthroscopic removal of calcium deposits as well as infraspinatus and supraspinatus muscle repair without relapse via minimal incision using suture anchors. This was a case of atypically extensive calcific tendinitis involving the infraspinatus muscle, with a bursal side partial rupture of the supraspinatus muscle in a 61-year-old female whose chief complaint was chronic pain of the right shoulder exacerbated by limited movement.

Characterizing the Progression of Varying Types of Calcific Tendinitis around Hip / 대한고관절학회지

PURPOSE: To assess the progression of clinical symptoms and disease course of calcific tendinitis in the hip region according to types of calcification. MATERIALS AND METHODS: Among patients with the hip pain, 28 patients (21 males and 7 females; mean age 51 years, range 32-74 years) showing calcified lesions in simple radiography without other possible sources of pain were analyzed retrospectively. Twelve patients displayed a symptom duration of less than three weeks (acute; average=1+/-0.9 week) and 16 displayed greater than three weeks (chronic; average=21.0+/-19.5 weeks). Lesions were classified as nodular (11, 39.3%), nodular-fragmented (13, 46.4%), or amorphous (4, 14.3%). Initial symptoms, progression of clinical features, radiological findings and prognosis were investigated and analyzed according to calcification type. RESULTS: In 15 patients (53.6%), lesions were located superior to the great trochanter. On average, the acute group was younger (44.58 vs. 55.44 years, P=0.006), suffered more (mean pain Numeric Rating Scale [NRS], 6.3 vs. 3.8; P<0.001), and recovered more (difference between initial and follow-up NRS, 5.1 vs. 2.63; <<0.001) than the chronic group. The mean length of initial lesions was longer in the acute group than the chronic group (15.8 vs. 9.1 mm, P=0.008). When compared to patients with distinctive margins (15, 53.6%), those with nondistinctive margins showed better improvement (difference between initial and follow-up NRS, 4.7 vs. 2.8; P=0.01) and more significant decrease in lesion size (difference between initial and follow-up length, 10.8 vs. 2.6 mm; P=0.003). CONCLUSION: Calcific tendinitis occurring in the hip area displayed a variety of characteristics. Although complaining of more severe pain in the initial phase, patients with acute pain or calcific lesions with nondistinctive margins showed better symptom improvement when compared to their counterparts.

Successful Treatment of Rectus Femoris Calcification with Ultrasound-guided Injection: A Case Report

Painful periarticular calcification most commonly occurs within the rotator cuff of the shoulder and rarely around the elbow, hip, foot, and neck. As acute inflammatory reaction develops, severe pain, exquisite tenderness, local swelling, and limitation of motion with pain occur. In case of calcific tendinitis of the shoulder, it can be easily diagnosed according to the symptoms and with x-ray. However, in lesions of the hip, as it is a rare location and usually involves pain in the posterolateral aspect of the thigh, which can simulate radicular pain from a lumbar intervertebral disc, it could be difficult to diagnose. Hence, physicians usually focus on lumbar lesions; therefore, misdiagnosis is common and leads to a delayed management. Here, we report the case of a 30-year-old female patient with calcific tendinitis of the rectus femoris that was successfully managed with ultrasound-guided steroid injection. This study offers knowledge about the rectus femoris calcification.

The Effect of Extracorporeal Shock Wave Therapy for Calcific Tendinitis of the Shoulder / 대한스포츠의학회지

To evaluate the functional and radiologic outcomes of extracorporeal shock wave therapy (ESWT) in shoulders with chronic calcific tendinitis. We report a retrospective study to compare the outcome after ESWT (group l, 15 cases) with the effect of medication treatment (group 2, 15 cases) in patients with chronic calcific tendinitis. Patients were aged 42 to 58 years, mean of 48 years and treated with extracorporeal shock waves or medication from September 2012 to May 2014. The ESWT was performed six cycles of shock waves, weekly treatment for the three cycles and the rest cycles after 2 weeks of pause. In the same period, there were 12 women and 3 men treated with medication treatment for calcific tendinitis. The clinical outcomes were evaluated according to Constant and Murley score and pain visual analogue scale. Radiologic evaluation was performed to confirm disintegration of calcific deposits 3 months and 6 months after treatment. Clinical outcomes were significantly improved in ESWT group, and there was significant difference between ESWT group and medication group. In radiographic evaluation, the calcific deposit was significantly decreased in ESWT group. ESWT therapy is more effective to achieve functional improvement and to alleviate pain in the patients with calcific tendinitis of the shoulder.

Complete Resolution of a Case of Calcific Tendinitis of the Longus Colli with Conservative Treatment

Acute calcific tendinitis of the longuscolli is a self-limiting inflammatory condition caused by calcium hydroxyapatite deposition in the longuscolli tendon. Although several case reports have described its radiological presentation, few reports provide detailed chronological accounts through symptomatic and radiologic resolution. A 59-year-old woman presented with severe neck pain and stiffness of a few days duration as well as moderate discomfort when swallowing. Lateral radiographs revealed a large calcium deposit anterior to the C1.C2 joint and swelling of the prevertebral soft tissue from C1 to C5. CT and magnetic resonance imaging showed fluid in the retropharyngeal gap.A soft collar and non-steroidal anti-inflammatory drug were prescribed, without antibiotics. At 4 months after presentation, the calcium deposit and all symptoms had resolved completely. Although this disease is comparatively rare, physicians should keep it in mind when a patient presents with acute severe neck pain.
