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.

Sawing Through The Neck - A Case of Serrated Fish Bone Migrating to Prevertebral Space

@#Fish bone is the commonest pharyngeal foreign body, however migrating fish bone is a rare occurrence. We report a case of a 54-year-old male who had history of fish bone ingestion over a week and presented with odynophagia and worsening neck pain. Rigid esophagoscopy revealed tip of a fish bone which was embedded in granulation tissue. The fish bone migrated further with manipulation. Aided with computed tomography scan findings, the serrated fish bone was finally removed via transcervical approach without any complication. In conclusion, high index of suspicion and prompt removal of migrating fish bone with the aid of computed tomography imaging is necessary to avoid fatal complications.

Comparison of prevertebral soft tissue swelling and dysphagia between Zero-p and traditional cage and titanium plate for anterior cervical discectomy with fusion / 局解手术学杂志

Objective To explore the relationship among the prevertebral soft tissue swelling and dysphagia rate after anterior cervical diskectomy and fusion(ACDF),and to investigate the prevertebral soft tissue swelling and dysphagia rate after Zero-p or traditionaI cage and titanium plate for one-level lesion of cervical myelopathy.Methods The clinical data of 54 patients with one-level lesion (C5/6) of cervical myelopathy who undelwent anterior cenrical discectomy and fusion by Zero-p (n =25) or traditional cage and titanium plate (n =29) were analyzed.The postoperative prevertebral soft tissue swelling was measured by lateral radiographs.Patients were divided into the swelling group (n =24) and the non-swelling group(n =30) based on the degree of prevertebral soft tissue swelling and the incidences of dysphagia were analyzed.Patients were divided into the Zero-p group (n =25)and the Cage group (n =29) based on surgical treatment,the postoperative prevertebral soft tissue swelling and dysphagia rate were compared.Results The rate of dysphagia in swelling group was 45.8％,which was higher than 13.3％ in non-swelling group,the difference was significant(P ＜0.05).The postoperative prevertebral soft tissue swelling was 6.22 mm averagely after Zreo-p,which was less than that after traditional cage and titanium plate for anterior cervical discectomy with fusion(9.25 mm),the difference was significant (P ＜ 0.05).The incidence of dysphagia in Zero-p group was 12％,which was lower than 41.4％ in Cage group,and the difference was statistically significant (P ＜ 0.05).Conclusion It is a clinical significance to evaluate the degree of prevertebral soft tissue swelling by cervical lateral X-ray after ACDF,when the degree of prevertebral soft tissue swelling is greater,the incidence of complications such as dysphagia is higher.In addition,The Zero-p for the treatment of single one-level lesion of cervical myelopathy(C5/6) has a lower degree of prevertebral soft tissue swelling and dysphagia rate than the traditional Cage and titanium plate fusion.

A Case of Glomangiopericytoma in the Prevertebral Space / 대한이비인후과학회지

Glomanigiopericytoma is a rare vascular neoplasm with a perivascular myoid phenotype. It is rarely found in the neck but most commonly in the nose and paranasal sinuses. We experienced a case of 72-year-old man who presented a 5-year history of a right neck mass. The pathologic diagnosis was glomangiopericytoma. We removed the mass transcervically and the patient showed no postoperative problem. We report this case with a review of literature.

It can lead to life threatening airway obstruction and dysphagia requiring early diagnosis and proper management to prevent consequences. We present a case of 5 month child with tubercular prevertebral and epidural abscess who presented with dysphagia and stridor. Child responded dramatically to anti-tubercular therapy and surgical drainage of abscess. The child is doing well on follow up.

Effect of selective beta-adrenoceptor blockade and surgical resection of the celiac-superior mesenteric ganglion complex on delayed liquid gastric emptying induced by dipyrone, 4-aminoantipyrine, and antipyrine in rats

There is evidence for participation of peripheral β-adrenoceptors in delayed liquid gastric emptying (GE) induced in rats by dipyrone (Dp), 4-aminoantipyrine (AA), and antipyrine (At). The present study aimed to determine whether β-adrenoceptors are involved in delayed GE induced by phenylpyrazole derivatives and the role of the prevertebral sympathetic nervous system in this condition. Male Wistar rats weighing 220-280 g were used in the study. In the first experiment rats were intravenously pretreated with vehicle (V), atenolol 30 mg/kg (ATE, β1-adrenergic antagonist), or butoxamine 25 mg/kg (BUT, β2-adrenergic antagonist). In the second experiment, rats were pretreated with V or SR59230A 2 mg/kg (SRA, β3-adrenergic antagonist). In the third experiment, rats were subjected to surgical resection of the celiac-superior mesenteric ganglion complex or to sham surgery. The groups were intravenously treated with saline (S), 240 µmol/kg Dp, AA, or At, 15 min after pretreatment with the antagonists or V and nine days after surgery. GE was determined 10 min later by measuring the percentage of gastric retention (%GR) of saline labeled with phenol red 10 min after gavage. The %GR (means±SE, n=6) values indicated that BUT abolished the effect of Dp (BUT+Dp vs V+Dp: 35.0%±5.1% vs 56.4%±2.7%) and At (BUT+At vs V+At: 33.5%±4.7% vs 52.9%±2.6%) on GE, and significantly reduced (P<0.05) the effect of AA (BUT+AA vs V+AA: 48.0%±5.0% vs 65.2%±3.8%). ATE, SRA, and sympathectomy did not modify the effects of treatments. These results suggest that β2-adrenoceptor activation occurred in delayed liquid gastric emptying induced by the phenylpyrazole derivatives dipyrone, 4-aminoantipyrine, and antipyrine. Additionally, the released neurotransmitter did not originate in the celiac-superior mesenteric ganglion complex.

Clinical significance of X-ray lateral radiograph for evaluating the postoperative prevertebral soft tissue swelling after anterior cervical fusion / 局解手术学杂志

Objective To explore the relationship among the prevertebral soft tissue swelling, surgical extent, surgical segments, and complications and to investigate the clinical significance of lateral radiographs for evaluating the postoperative prevertebral soft tissue swelling. Methods 123 patients who underwent anterior cervical fusion with plate augmentation for cervical spondylosis were included in this study. The postoperative prevertebral soft tissue swelling was measured by lateral radiographs. The data were analysed according to surgical extent and surgical segments. Patients were divided into the swelling group (61cases, >9. 98 mm) and the non-swelling group (62 cases, <9. 98 mm) based on the degree of prevertebral soft tissue swelling. The incidences of complications, such as dyspnea and dysphagia, were ana-lysed. Results The rate of dyspnea was 21. 3% in swelling group, which was higher than 8. 1% in non-swelling group (P<0. 05). The rate of dysphagia was 83. 6% in swelling group, which was higher than 25. 8% in non-swelling group (P<0. 05). In addition, postoperative prevertebral soft tissue swelling was 8. 29 mm averagely after one-level fusion, which was less than that after two or more levels fusion (11. 55 mm and 10. 40 mm) (P<0. 05). Postoperative prevertebral soft tissue swelling was 10. 94 mm after high-level fusion (above C4), which was more than that low-level fusion (below C5) (8. 63 mm) (P<0. 05). Conclusion After anterior cervical fusion for cervical spondylosis, when the degree of prevertebral soft tissue swelling is greater the incidences of complications such as dyspnea and dysphagia might be higher. In addition, prevertebral soft tissue swelling increments are significantly greater in patients who had undergone multi-level or high-level fusion ( above C5 ) . Evaluation of prevertebral soft tissue swelling using lateral radiographs is a clinically meaningful procedure.

Anomalous Origin of Left Vertebral Artery Arising from the Arch of Aorta and Its Embryological Basis.

Background and Aim: Arterial disarrangements within the thorax are common and assume many diverse forms. The anatomic and morphologic variation of the origin and course of the prevertebral segment of the vertebral artery is necessary for vascular radiology, planning of aortic arch surgery or endovascular interventions. The present study is aimed at finding the origin and course of the left vertebral artery from the arch of aorta between left common carotid and left subclavian arteries. Materials and Methods: Present study was done on six formalin fixed cadavers during routine dissection allotted for the first year students of Kanyakumari Government Medical College Asaripallam, Nagercoil. The direct dissection method was used. A comparative analysis was done with previous studies. Result: Usually the vertebral artery arises from supero-posterior aspect of the first part of the subclavian artery. But in a 60 yrs old adult female cadaver showed a variation, that the arch of aorta gave off four branches in which the left vertebral artery arose as 3rd branch between the left common carotid and left subclavian arteries. Conclusion: Variation observed in the study is in par with variation observed in previous studies. The knowledge about the variant origin of left vertebral artery is necessary for interventional radiologists and surgeons to avoid complications in the head and neck region.

A 'pen' in the neck: An unusual foreign body and an unusual path of entry.

Penetrating injuries to head and neck region with varying objects have been reported in the literature. [1],[2],[3],[4],[5],[6],[7],[8],[9],[10] Majority of these injuries occur in interpersonal violence or bomb blasts or road traffic accidents. Despite the improvement in imaging technologies and surgical methods, penetrating injuries to head and neck with impacted foreign bodies are very challenging due to the proximity to vital structures and/or difficulties in accessing them for the removal. [1] Following injury the normal anatomy could be altered because of edema or tissue destruction, which makes the diagnosis or retrieval more difficult. [3] Parapharyngeal or prevertebral space is an unusual place for lodgment of foreign bodies and in these cases the usual point of entry is the oral cavity, cheek or neck. Here, we report a case of a ball point pen extending to the prevertebral region at the level of C1-C2 vertebrae from point of entry at the suprazygomatic region in the temporal fossa.

Negative Pressure Pulmonary Edema Associated with Anterior Cervical Spine Surgery

We report a very rare case of negative pressure pulmonary edema (NPPE) that occurred immediately after anterior cervical discectomy and fusion (ACDF). The patient was a 25-year-old man who sustained a facet fracture-dislocation of C5 during a traffic accident. After ACDF, he developed NPPE and needed mechanical ventilation. Fortunately, he recovered fully within 24 hours. NPPE is a rare postoperative complication that may occur after cervical spine surgery. The aims of this report are to present information regarding the diagnosis and emergent treatment of NPPE, and to review the previous literature regarding this serious complication.

Comparative Study of Clinical and Radiological Outcomes of a Zero-Profile Device Concerning Reduced Postoperative Dysphagia after Single Level Anterior Cervical Discectomy and Fusion

OBJECTIVE: This study analyzed clinical and radiological outcomes of a zero-profile anchored spacer (Zero-P) and conventional cage-plate (CCP) for single level anterior cervical discectomy and fusion (ACDF) to compare the incidence and difference of postoperative dysphagia with both devices. METHODS: We retrospectively reviewed our experiences of single level ACDF with the CCP and Zero-P. From January 2011 to December 2013, 48 patients who had single level herniated intervertebral disc were operated on using ACDF, with CCP in 27 patients and Zero-P in 21 patients. Patients who received more than double-level ACDF or combined circumferential fusion were excluded. Age, operation time, estimated blood loss (EBL), pre-operative modified Japanese Orthopaedic Association (mJOA) scores, post-operative mJOA scores, achieved mJOA scores and recovery rate of mJOA scores were assessed. Prevertebral soft tissue thickness and postoperative dysphagia were analyzed on the day of surgery, and 2 weeks and 6 months postoperatively. RESULTS: The Zero-P group showed same or favorable clinical and radiological outcomes compared with the CCP group. Postoperative dysphagia was significantly low in the Zero-P group. CONCLUSIONS: Application of Zero-P may achieve favorable outcomes and reduce postoperative dysphagia in single level ACDF.

Prognostic impact of MRI-detected prevertebral space involvement in nasopharyngeal carcinoma / 中华放射肿瘤学杂志

Objective To evaluate the prognostic impact of MRI-detected prevertebral space involvement in nasopharyngeal carcinoma (NPC) treated with radiotherapy and chemotherapy.Methods A retrospective analysis was performed on the clinical data of 333 patients who had newly diagnosed biopsyproven NPC without distant metastasis from 2005 to 2007.All patients underwent MRI scans of the nasopharynx and neck and were treated with two-and three-dimensional radiotherapy without or without chemotherapy.The Kaplan-Meier method was used to calculate overall survival (OS),distant metastasis-free survival (DMFS),and locoregional relapse-free survival (LRFS),and the log-rank test was used for survival difference analysis;the Cox proportional hazards regression analysis was used to assess the prognostic value of prevertebral space involvement.Results The follow-up rate was 95.2％.Prevertebral space involvement was seen in 139(41.7％) of these patients.The patients with prevertebral space involvement had significantly higher T stage and clinical stage than those without prevertebral space involvement (x2 =90.41,P =0.000;x2 =54.03,P =0.000).The 5-year OS,DMFS,and LRFS for NPC patients with and without prevertebral space involvement were 58.8％ vs.77.5％ (x2 =11.95,P =0.000),77.8％ vs.85.0％(x2=2.56,P=0.110),and 88.3％ vs.91.8％ (x2=1.51,P=0.220),respectively.After adjusting for N stage,a significant difference was still seen between the two groups with regard to 5-year OS (x2 =9.93,P =0.002).The multivariate analysis showed that prevertebral space involvement was not the independent prognostic factor for OS,DMFS,and LRFS (x2 =0.43,P =0.512 ; x2 =0.08,P =0.783 ; x2 =0.00,P =0.971).Conclusions The frequency of prevertebral space involvement is very high in NPC.The OS for the patients with prevertebral space involvement is significantly lower than those without prevertebral space involvement.But prevertebral space involvement is not the independent prognostic factor in NPC patients.

We report here a case of dyspnea due to an extensive prevertebral hematoma by soft tissue injury without cervical vertebral fracture and/or dislocation and a review the relevant literature.

Efficacy of Postoperative Radiograph for Evaluating the Prevertebral Soft Tissue Swelling after Anterior Cervical Discectomy and Fusion

BACKGROUND: After surgery for degenerative spinal disease by the anterior approach, the degree of soft tissue swelling can be assessed simply using plain radiographs. However, there are little studies according to the surgical methods or extent of surgery, and no study had addressed the clinical meaning of swelling determined by plain radiography. The purpose of this study was to evaluate the clinical significance of prevertebral soft tissue swelling (PSTS) after anterior cervical fusion with plate fixation for the treatment of degenerative cervical spinal disorders. METHODS: One hundred and thirty-five patients that underwent anterior cervical fusion with plate augmentation for degenerative cervical spondylosis were included in this study. PSTS differences were analyzed with respect to numbers of fusion segments and location of fusion. Cases were divided into two groups based on the amount of PSTS, and incidences of dyspnea, dysphagia, dysphonia were evaluated. RESULTS: PSTS increments were significantly greater in patients that had undergone multi-level or high-level fusion. Complications of dyspnea, dysphagia and dysphonia were found more frequently in patients with marked PSTS group. CONCLUSIONS: Increments of PSTS after anterior cervical fusion for degenerative spinal disorders are greater and incidences of complications are higher in patients that undergo multi-level or high-level fusion. Thus, measurement of PSTS using consecutive cervical lateral radiographs after anterior cervical surgery is clinically meaningful procedure.

Aspectos de imagem na tendinite calcária pré-vertebral / Imaging findings in acute calcific prevertebral tendinitis

A tendinite calcária aguda pré-vertebral é uma condição benigna e rara que apresenta calcificação das fibras do músculo longo do pescoço com reação inflamatória local, sendo esta uma das formas de apresentação menos frequentes da doença por deposição de hidroxiapatita de cálcio. Manifesta-se com dor cervical aguda e/ou odinofagia, podendo ser erroneamente diagnosticada como abscesso retrofaríngeo, espondilodiscite ou alteração decorrente de trauma. Os achados radiológicos na tendinite calcária pré-vertebral são patognomônicos. O conhecimento de tais achados é muito importante, pois o correto diagnóstico possibilita a resolução precoce dos sintomas e evita intervenções desnecessárias em um paciente que apresenta afecção com boa resposta ao tratamento conservador.

Acute calcific prevertebral tendinitis is a benign and rare condition that presents calcification of the superior oblique fibers of longus colli muscle with local inflammatory reaction. Such condition is one of the less common presentations of calcium hydroxyapatite deposition disease. Clinical signs are usually acute neck pain and odynophagia, and it may be misdiagnosed as retropharyngeal abscess, spondylodiscitis or traumatic injury. The imaging findings in calcific prevertebral tendinitis are pathognomonic. The knowledge of such findings is extremely important to avoid unnecessary interventions in a patient presenting a condition with a good response to conservative treatment.

Spontaneous Retropharyngeal Hematoma: A Case Report

Spontaneous retropharyngeal hematoma is rare and difficult to diagnosis early. A 23-year-old male spontaneously developed acute onset of neck pain, limitation of neck motion, and mild dysphagia. Magnetic resonance imaging demonstrated blood products in prevertebral space from C2 to C4, suggesting a diagnosis of retropharyngeal hematoma. We report a rare case of spontaneous retropharyngeal hematoma causing neck pain.

Airway Obstruction Caused by Prevertebral Soft Tissue Swelling after Anterior Cervical Discectomy and Fusion: A Case Report / 대한구급학회지

Acute airway obstruction after anterior cervical surgery is rare, but does occur. Airway obstruction due to prevertebral soft tissue swelling is unpredictable, but potentially lethal. We managed a 67-year-old male who developed acute airway obstruction caused by marked prevertebral soft tissue swelling on the first day after anterior cervical discectomy and fusion at the C4-C5 level.

The effects of local anesthetic distribution on symptoms using ultrasound image after stellate ganglion block / 대한마취과학회지

BACKGROUND: The aim of this study is to evaluate the effects of local anesthetic distribution on symptoms using ultrasound image after C6 stellate ganglion block (SGB). METHODS: Twenty-six patients underwent SGB via an anterior paratracheal approach at the sixth cervical level using 6 ml of 1% mepivacaine. We divided the patients into two groups by local anesthetic distribution using ultrasound image after SGB. In the group 'sub', injected local anesthetic was beneath the prevertebral fascia. In the group 'supra', some of injected local anesthetic was above the prevertebral fascia. The occurrence of Horner's syndrome, warm sensation on the face and hand, brachial plexus block, hoarseness, and foreign body sensation in the throat were evaluated. The skin temperature of the bilateral thumbs was measured pre and post SGB. RESULTS: The occurrence of hoarseness and the foreign body sensation in the throat was significantly reduced in the group 'sub' than the group 'supra' (P<0.05). The skin temperature of the ipsilateral thumb significantly increased in both groups compared to the pre SGB values, and the change of the skin temperature significantly increased in the group 'sub' than the group 'supra' (P<0.05). CONCLUSIONS: Subfascial distribution of local anesthetic under ultrasound image after SGB reduces the typical complications. It is more effective in the sympathetic block than suprafascial distribution.

Prevertebral Soft Tissue Swelling after Anterior Cervical Discectomy and Fusion: Comparison between Plate Fixation and Cage Insertion / 대한정형외과학회잡지

PURPOSE: We wanted to identify the natural course of prevertebral soft tissue swelling after performing one-level or two-level anterior cervical discectomy and fusion (ACDF), and we compared the prevertebral soft tissue swelling between the plate and cage groups, and we wanted to help preventing potentially lethal airway complications after ACDF. MATERIALS AND METHODS: One hundred thirteen patients who underwent one-level or two-level ACDF with plate and screws or cages were studied. Eighty-seven patients underwent ACDF using plates and twenty-six underwent ACDF using cages. Cervical spine lateral radiography was taken preoperatively, on the immediate postoperative day and on the 1st, 2nd, 3rd, 4th and 5th days after surgery. The prevertebral soft tissue was measured from C2 to C6 on the cervical spine lateral radiography. RESULTS: Prevertebral soft tissue swelling occurred postoperatively and the peak level was found on the second and third days after surgery. The prevertebral soft tissue swelling was gradually decreased from the fourth day after surgery. Prominent swelling of the prevertebral soft tissue was found at the 2nd, 3rd and 4th cervical spines. There were no significant differences of the prevertebral soft tissue swelling between the one-level and two-level ACDF groups. The cage insertion group showed less swelling than did the plate fixation group. CONCLUSION: The peak prevertebral soft tissue swelling was found on the second and third days after surgery. The cage insertion group showed less swelling than did the plate fixation group.
