Grisel's Syndrome Induced by Mycobacterium tuberculosis

Challenges in Grisel's Syndrome Management in a Two-Month-Old Infant

Grisel's syndrome (GS) is a rare neurosurgical condition involving nontraumatic rotatory subluxation of the atlantoaxial joint. This case report presents a two-month-old infant girl, the youngest reported case of this syndrome based on our literature review to the date of this publication. The infant was initially referred to our hospital as a case of the arachnoid cyst but was subsequently neuroradiologically diagnosed with GS, which was believed to be secondary to a retropharyngeal abscess. After developing weakness and developmental delay as well as failing conservative management for two years, the infant underwent C1 laminectomy and occipitocervical sublaminar wire fusion with favorable outcomes. GS should be considered a differential even if the patient does not present with typical signs such as torticollis and neck pain. If not identified early and treated effectively, it can result in severe neurological damage. The management plan largely depends on the Fielding-Hawkins grade of subluxation and the timing of diagnosis.

A case of adult-onset Grisel's syndrome

Aim: Grisel's syndrome is a non-traumatic subluxation of the atlanto-axial joint that occurs after infection or inflammation in the otolaryngological area, primarily in children.Method: This report describes the clinical characteristics of an extremely rare case of adult-onset Grisel's syndrome.Result: A 77-year-old woman presented with neck and bilateral shoulder pain and stiffness. Her temperature was 37.6 °C. Blood testing revealed a mildly elevated inflammatory response, although blood cultures were negative. Computed tomography (CT) showed atlanto-axial subluxation and joint destruction. T2-weighted magnetic resonance imaging (MRI) displayed high signals in the soft tissues in the anterior space of the atlas and axis, posterior wall of the pharynx, and interspinous ligament, indicating spinal cord compression at the C1 level. Differential diagnoses of inflammation and diseases causing atlanto-axial subluxation included rheumatoid arthritis, amyloidosis, pyogenic spondylitis due to posterior pharyngeal abscess, and crowned dens syndrome. After the systematic elimination of each condition, we considered Grisel's syndrome and began non-surgical treatment with intravenous antibiotics and a Philadelphia neck collar. Her inflammatory response and neck pain gradually decreased. Six months later, there was no progression of instability. She was able to walk unaided and live normally with the use of a neck collar as needed.Conclusion: Grisel's syndrome occurs predominantly in children, but can also afflict adults. Since early diagnosis and treatment can improve symptoms in some cases and prevent progressive atlanto-axial instability, prompt evaluation of the atlanto-axial joint using CT or MRI is advised in patients with neck pain and limited range of motion.

Grisel's syndrome associated with mumps: A case report

Grisel's syndrome (GS) is defined as atlantoaxial rotatory subluxation/fixation not associated with trauma or bone disease, usually following head and neck infection/inflammation or ear, nose, and throat (ENT) surgery. Many conditions could lead to Grisel's syndrome, of which mumps is rarely to be seen. This report discusses a case of GS in children with Type I atlantoaxial joint subluxation and previously diagnosed mumps. A 6-year-old boy who had cervical pain and torticollis for 2 weeks was admitted to our hospital. There was no trauma and he had not had ENT surgery but was diagnosed with mumps 2 weeks previously due to swelling of the left cheek and cervical lymph node. Physical examination and computed tomography confirmed a diagnosis of Grisel's syndrome with an ADI (atlanto-dens interval) of 1.6 mm. The patient then received occipito-mandibular traction for 6 days and recovered. No recurrence was observed at 1 year follow-up. Physicians should raise awareness of this rare complication of mumps to avoid life-threatening neurological impairments owing to Grisel's syndrome.

Magnetic Resonance Imaging as the Primary Imaging Modality in Children Presenting with Inflammatory Nontraumatic Atlantoaxial Rotatory Subluxation

Inflammatory nontraumatic atlantoaxial rotatory subluxation (AAS) in children is an often-missed diagnosis, especially in the early stages of disease. Abscess formation and spinal cord compression are serious risks that call for immediate surgical attention. Neither radiographs nor non-enhanced computed tomography (CT) images sufficiently indicate inflammatory processes. Magnetic resonance imaging (MRI) allows a thorough evaluation of paraspinal soft tissues, joints, and ligaments. In addition, it can show evidence of vertebral distraction and spinal cord compression. After conducting a scoping review of the literature, along with scientific and practical considerations, we outlined a standardized pediatric MRI protocol for suspected inflammatory nontraumatic AAS. We recommend contrast-enhanced MRI as the primary diagnostic imaging modality in children with signs of torticollis in combination with nasopharyngeal inflammatory or ear nose and throat (ENT) surgical history.

Grisel's Syndrome in an Adult After Endoscopic Nasopharyngectomy

Background

Grisel's syndrome is rare in adults, and is characterized by nontraumatic atlanto‐axial subluxation secondary to infection. Here, we report a case of Grisel's syndrome occurring after endoscopic nasopharyngectomy.

Methods

A 67‐year‐old man complained of fever and neck pain with reduced lateral rotation after an endoscopic nasopharyngectomy for recurrent nasopharyngeal carcinoma. Flexion and extension X‐rays of the cervical spine demonstrated atlanto‐axial subluxation, and magnetic resonance imaging showed infective changes with cervical osteomyelitis. A diagnosis of Grisel's syndrome with cervical spine osteomyelitis was made. A later computed tomography (CT) scan demonstrated subluxation of C1 on C2, as well as the occipital‐C1 joint.

Results

The patient was treated with intravenous antibiotics and offered surgery for spinal stabilization, but declined. He remained well 15 months post‐op on a cervical collar with minimal pain and no neurologic deficits.

Conclusion

A high index of suspicion for Grisel's syndrome is suggested in patients who have neck pain with reduced range of motion postnasopharyngectomy, and imaging is useful in clinching the diagnosis.

Grisel's syndrome caused by Mycoplasma pneumoniae infection: a case report and review of the literature

BACKGROUND

Grisel's syndrome is a non-traumatic subluxation of the atlantoaxial joints, which is caused by an inflammatory process involving the upper neck. Torticollis, neck pain, and reduced neck mobility are the main clinical signs of presentation. Predisposing factors are trauma, hyperlaxity of the transverse and alar ligaments of the atlantoaxial joints, and surgical interventions carried out in this area. Several viral and bacterial pathogens have been reported as causative events of Grisel's syndrome, including Epstein-Barr virus, Kawasaki disease, Streptococcus pyogenes, Staphylococcus aureus, and other infectious agents. Grisel's syndrome linked to Mycoplasma pneumoniae infection as the trigger has not previously been reported. Mycoplasma pneumoniae is a small prokaryotic microbe and a frequent etiologic factor of respiratory tract infections and, less frequently, of extrapulmonary body organs. The recognition of the Grisel's syndrome is based on clinical and neuroradiological investigations, and early diagnosis and specific treatment are crucial to the successful outcome of the disease.

RESULTS

We report the case of an 8-year-old girl with Grisel's syndrome caused by an upper respiratory tract infection due to Mycoplasma pneumoniae. Diagnostic suspicion and treatment of Grisel's syndrome were established quickly by anamnestic and clinical data and confirmed by radiological findings. The girl was immediately treated with specific antibiotic therapy and cervical immobilization, thus preventing the most dangerous complications of the disorder.

CONCLUSION

Mycoplasma pneumoniae, among the other infectious agents, may be cause of scute torticollis and Gresel's syndrome.

Grisel's Syndrome: Non-traumatic Atlantoaxial Rotatory Subluxation-Report of Five Cases and Review of the Literature

BACKGROUND

In children, when unresponsive neck rigidity and distress are observed after ear, nose and throat (ENT) surgical treatment or nasopharyngeal inflammation, Grisel's syndrome should be suspected. This is a rare syndrome involving non-traumatic rotatory subluxation of the atlantoaxial joint. Conservative management with external cervical orthoses and empirical antibiotic, muscle relaxant and analgesic therapy should be the first choice of treatment. Surgical stabilization is indicated when high-grade instability or failure of stable reduction are observed. The instability is graded according to the classification system devised by Fielding and Hawkins. Several recommendations for treatment are available in the literature, but there are no common guidelines. In this paper, the authors discuss the need for prompt diagnosis and treatment considerations.

CASE DESCRIPTION

Five children with Fielding type I-III rotatory subluxation are reported. Three patients were treated with a cervical collar, and one patient was treated with skull traction and sternal-occipital-mandibular immobilizer (SOMI) brace application. Surgical treatment was necessary for one patient after failure of initial conservative management. The intervals between the onset of torticollis and radiological diagnosis ranged from 12 to 90 days. A relationship between an increased grade of instability and delayed diagnosis was observed.

CONCLUSION

In children with painful torticollis following ENT procedures or nasopharyngeal inflammation, Grisel's syndrome should always be suspected. Cervical magnetic resonance imaging (MRI) allows prompt and safe diagnosis, and a three-dimensional computed tomography (CT) scan provides better classification of the instability. Surgery, which is indicated in cases of high-grade instability or failure of conservative treatment, may be avoided with prompt diagnosis.

Grisel Syndrome in Otolaryngology: A Case Series with Literature Review

Grisel's syndrome is non traumatic atlanto axial subluxation usually associated with inflammatory conditions of head and neck region. Non traumatic atlanto axial joint subluxation is a rare entity for an unsuspecting otolaryngologist. The condition if missed and not treated properly can have serious implications with possible neurological deficit. We attempt to review the existing literature on the disease condition and also to highlight the proper management of the condition. Retrospective analysis of hospital record of last five years and an internet based literature survey on the current concepts and management of the condition. We have come across five cases of Grisel's syndrome over the last five years. The clinicopathological and radiological features are described. Grisel syndrome may remain undiagnosed at initial presentation if not suspected. Delayed diagnosis may result in life long morbidity for the patient and the need for surgical intervention. Many of the early cases can be treated successfully by conservative approach.
