Acute neck pain in the ED: Consider longus colli calcific tendinitis vs meningitis

Calcific Tendinopathy Atypically Located Outside the Rotator Cuff: A Systematic Review

BACKGROUND AND PURPOSE

Calcific tendinopathy is a common cause of painful shoulder easily identified with ultrasound or conventional radiography. Although the rotator cuff is by far the most common location of the disease and diagnostic or treatment strategies are well known in clinical practice, a lack of awareness characterizes the assessment of the other sites affected by this condition; consequently, the risk of underestimating the prevalence of atypical non-rotator cuff calcific tendinopathy is high. This may lead to expensive or invasive diagnostic exams and/or inappropriate treatment, whereas the condition is usually self-limited. The present study aims at analysing the frequency of calcific tendinitis in uncommon sites, in order to fill a gap in knowledge and awareness regarding non-rotator cuff calcific tendinopathy, thus avoiding improper clinical choices and helping to identify this condition.

METHODS

This systematic review was conducted following the PRISMA guidelines. We performed a search on Pubmed and Scopus databases concerning atypically sited extra-rotator cuff calcific tendinopathy published since 1950.

RESULTS

The research found a total of 267 articles and 793 non-rotator cuff cases of calcific tendinopathy registered. The spine (213 – 26.86%), foot and ankle (191 – 23.95%), and hip (175 – 22.06%) appeared to be the most common sites of calcific tendinopathy after the rotator cuff, whereas the longus colli C1-C2 (204 – 25.72%), Achilles (173 – 21.81%), and rectus femori (61 – 7.69%) were the most commonly affected tendons.

CONCLUSION

A better awareness of this condition in several different sites of the body than the rotator cuff could avoid unnecessary choices both in assessment and treatment.

Acute Calcific Tendonitis of the Longus Colli: An Uncommon Cause of Neck Pain in the Emergency Department

The longus colli muscle has three major parts that originate and insert in the upper cervical and thoracic spine. It is a weak flexor of the neck, and when contracted also serves to rotate the neck to the ipsilateral side. It is innervated by the anterior rami of the C2-C6 spinal nerves and receives its blood supply from the anterior cervical and inferior thyroid arteries. In a post motor vehicle collision (MVC) patients presenting weeks later, the physician has to ensure there is no subacute fracture. Clinically, these patients present with severe anterior neck pain that will often be described as a deep pain.

A 43-year-old female with a past medical history of diabetes and prior surgical history of a tonsillectomy and uvulectomy presented with sudden onset of sore throat that woke her up from sleep at 3:00 am. Associated with the sore throat, she had hoarseness of her voice, difficulty breathing and felt that her throat was closing. She forced herself to vomit and then felt better. She denied any fevers or chills. Later, the patient mentioned that she had chronic neck pain from a prior accident and had been told that she has C5-C6 stenosis. About a week prior, she had been involved in another MVC and had some neck pain after that. Significantly, she was also on lisinopril for her hypertension (HTN). She was tolerating secretions, protecting her airway and no gross inflammation was noted on physical exam. On labs, there was no leukocytosis noted. Soft tissue neck X-ray showed reversal of the cervical lordosis, degenerative and erosive changes at C4-C5 and C5-C6, and thickening of the prevertebral soft tissues. She obtained a CT of the neck and cervical spine that showed osteophyte complexes at C4-C5 and C5-C6, as well as calcific tendonitis of the longus colli with a moderate amount of prevertebral free fluid. Neurosurgery was consulted from the ED who recommended getting an MRI of the neck, and consulting ENT as well. ENT happened to be in the ED and performed a bedside laryngoscopy that showed edema of the left arytenoid with full functionality of the vocal cords, and no signs of airway compromise. The patient was started on steroids, antibiotics, H2 blockers, and the ACE-inhibitor was discontinued due to suspected angioedema per ENT. She was also admitted to the ICU for airway monitoring. The MRI of the neck again showed calcific tendonitis of the longus colli with moderate prevertebral fluid. Meanwhile, the patient had complete resolution of her symptoms in 24 hours and she was cleared from both neurosurgery and ENT to be discharged. Acute calcific tendonitis is due to the deposition of calcium hydroxyapatite, which can cause significant pain and edema. In terms of calcific tendonitis of the longus colli muscle, this condition is frequently misdiagnosed and continues to be a challenge, especially in the emergency department. The differential diagnosis is diverse in etiology and severity, ranging from meningitis and retropharyngeal abscess to vertebral fracture and muscle strain.

Longus Colli Tendinitis: The Lost Twin of Retropharyngeal Abscess

Longus colli calcific tendinitis is a rare condition which mimics the alarming condition, retropharyngeal abscess. Clinically, the patient presents which acute cervical pain, dysphagia and fever. Since this condition is little known to otorhinolaryngologists, it is usually misdiagnosed as a retropharyngeal abscess which is more common. This is a case report of a 52 year old female who presented with complaints of neck pain and difficulty in swallowing along with fever which were acute in onset. Clinically, the symptoms overlapped with those of a retropharyngeal abscess. The diagnosis was confirmed as longus colli calcific tendinitis. Longus colli calcific tendinitis is a rare entity which can be diagnosed solely based on radiological investigation. The knowledge of this disease is crucial to otorhinolaryngolists as it avoids over treatment, unwarranted chance surgical exposure.

Vertigo caused by longus colli tendonitis: A case report and literature review

RATIONALE

Tendinitis of the longus colli muscle is an aseptic inflammatory process leading to acute posterior neck pain, neck stiffness, and dysphagia or odynophagia. We present a patient exhibiting an infrequent symptom, vertigo. This is the first description of the occurrence of vertigo symptoms caused by longus colli tendinitis.

PATIENT CONCERNS

A 38-year-old man was diagnosed with vertigo, presenting with a 1-month history of dizziness, palpitations, and numbness in the hands.

DIAGNOSIS

Longus colli tendinitis. The diagnosis was established using magnetic resonance imaging fat-suppression sequences.

INTERVENTIONS

Treatment with corticosteroid injections and acupotomy.

OUTCOMES

The symptoms relieved immediately after the treatment and complete resolution of the symptoms was observed after 1 week.

LESSONS

Longus colli tendinitis with vertigo is an under-reported condition in the literature and physicians should be aware of its existence. A lack of familiarity with the anatomy of the prevertebral space and its variable radiographic appearance makes the diagnosis of longus colli tendinitis clinically difficult. Misdiagnosis of this condition may lead to unnecessary interventions in vertigo.

Case reports about an overlooked cause of neck pain: calcific tendinitis of the longus colli: Case reports

STUDY DESIGN

Case description.

OBJECTIVE

Acute calcific tendinitis of the longus colli muscle is a rare clinical entity that causes severe neck pain. This entity is not well recognized due to its nonspecific presentation such as acute neck pain, neck stiffness, and odynophagia. The importance of this disease with a review of the literature is presented.

SUMMARY OF BACKGROUND DATA

Acute calcific tendinitis of the longus colli muscle is an inflammatory condition caused by deposition of calcium hydroxyapatite in the superior oblique tendon fibers of the longus colli muscle. It can be misdiagnosed as other life-threatening conditions including retropharyngeal abscess, resulting in unnecessary medical or surgical interventions.

METHODS

We retrospectively reviewed the clinical data, radiological features, and laboratory reports of 8 patients who were diagnosed with acute calcific tendinitis of the longus colli muscle and seen at our institution between April 2008 and March 2015 in this article. We describe the clinical presentation, diagnosis, and treatment of acute calcific tendinitis of the longus colli muscle.

RESULTS

There were 5 men and 3 women who ranged in age from 41 to 49 years (mean age: 44.5 years). The associated symptoms included neck pain, stiffness, odynophagia, and headache. The duration of symptoms varied from 2 days to 1 week. All patients showed calcific deposition inferior to the anterior arch of the atlas, and prevertebral effusion extending from C1 to C4. All patients were treated with NSAIDs and immobilization with a cervical brace, and most patients showed complete resolution of symptoms within 1 week.

CONCLUSION

We report 8 cases of acute calcific tendinitis of the longus colli, and describe the symptoms and radiological findings in detail. Awareness of this rare, benign, and self-limiting disease entity with characteristic radiologic findings is essential for early diagnosis and to avoid unnecessary medical and surgical interventions.
