Sentinel ear bleed as a presenting sign for carotid artery blowout due to aspergillus abscess in parapharyngeal space in an immunocompetent infant.

Parapharyngeal abscesses leading to complications, although rare after the advent of antibiotics, can lead to serious complications. One such complication is carotid erosion that can lead to a potentially fatal carotid artery blowout. We report a case of a previously healthy infant who presented with fever, ear bleed and progressively increasing swelling in the right side of his neck that led to airway compromise. The child required immediate securing of the airway at presentation. Imaging revealed lobulated abscess with multiple bleeding points eroding the carotid vessels, along with internal jugular venous thrombus. Surgical exploration was done and abscess debulked. Histopathology revealed aspergillus, which was treated with antifungals. He was discharged on oral warfarin after 40 days of hospital stay and remains well on follow-up. Sentinel ear bleed warrants close observation for possibility of carotid artery blowout in children with parapharyngeal abscesses.

[Internal carotid artery pseudoaneurysm caused by parapharyngeal abscess: A case report].

Pseudoaneurysms of the neck are seldom, and those caused by neck infections especially parapharyngeal abscess are even rarer. However, it is life-threatening and may bring sudden death due to the obstruction of airway and the pseudoaneurysms rupture. We analyzed the clinical features, diagnosis and treatment of the disease through a case summary and literature review in order to guide clinical diagnosis and treatment of pseudoaneurysms. The patient, whom we presented was an 87-year-old male and admitted in emergency of our hospital with the chief complaint of neck swelling for 7 days and shortness of breath for 2 days. Cervical ultrasound examination showed that there was an liquid dark area next to the left common carotid artery which was approximately 8.0 cm × 5.0 cm, consideration of formation of left carotid artery pseudoaneurysm, and the liquid dark area which was visible on the right considered of pseudoaneurysm or infection. Angiography of neck showed a clustered high-density shadow around the bifurcation of the left carotid artery, with an overall range of approximately 65 mm × 52 mm × 72 mm, the pseudoaneurysms for sure, while on the right side of the lesion, mixed low density shadows with air could be seen, the parapharyngeal abscess for sure.Then he was diagnosed as the pseudoaneurysm of left internal carotid artery which was caused by parapharyngeal abscess. After tracheal intubation and anti-infection treatment, the patient died due to hemorrhagic shock of the ruptured of the pseudoaneurysm. Morever we performed literature search on PubMed, Wanfang database and CNKI with keywords of "neck pseudoaneurysm, neck infection, parapharyngeal abscess" and enrolled 10 cases. Then we summarized the clinical characteristics and treatment. We analyzed and summarized the 10 case reports, in which the number of male was 7. Among them, there were 4 pediatric, and 6 adults were enrolled overall. Most of the symptoms were neck swelling, and the diseased blood vessel was mainly the right internal carotid artery which accounted for half overall. All the patients underwent surgical intervention, and recovered well. So we draw the conclusion that the clinical incidence of cervical pseudoaneurysms is low and can be caused by a variety of factors, especially caused by infectious factors. When a patient has a progressive pulsating mass in the neck, the preliminary diagnosis should be made by ultrasound as soon as possible, and the aortic enhancement CT should be used to further confirm.For a patient with cervical pseudo-aneurysms caused by parapharyngeal infections, he should take operation timely combined with antibiotic treatment in time.

A Rare Case of Extracranial Schwannoma of the Hypoglossal Nerve Located in the Parapharyngeal Space Mimicking a Deep Neck Abscess.

Schwannomas are neurogenic benign tumors originating from the myelin sheath of peripheral nerves, and hypoglossal Schwannomas account for 5% of nonvestibular ones. Extracranial localizations are substantially rare, especially those affecting exclusively the parapharyngeal space; for this reason, the retrostyloid neoformations could initially masquerade as a carotid tumor or deep organized neck abscess. The purpose of this report is to highlight the importance of a multidisciplinary approach in the correct management of differential diagnosis.

Pediatric deep neck infections: Clinical description and analysis of therapeutic management.

OBJECTIVES: The aim of our study was to describe clinical presentations, bacteriological results, and therapeutic management in a pediatric population presenting with acute pharyngeal suppuration. A further aim was to identify clinical, bacteriological, and radiological predictors of success associated with exclusive medical treatment. METHOD: A retrospective study was carried out including patients under 18 years of age hospitalized between January 1, 2015 and December 31, 2017 in our center for acute pharyngeal suppuration. We identified three groups of patients: group A, treated with exclusive intravenous antibiotics; group B, surgically treated after 48 h of appropriate antibiotic therapy, due to persistent fever and/or clinical worsening and/or persistence of a collection on follow-up imaging; group C, surgically treated as first-line therapy in association with intravenous antibiotics. A total of 83 patients were included: 36 in group A, 12 in group B, and 35 in group C. These three groups were compared for several variables: age of the patients, polynuclear neutrophil counts, diameter of the collections (the largest diameter found on imaging), duration of antibiotic therapy, delay before return to apyrexia, and hospitalization duration. RESULTS: A neck mass and torticollis were present, respectively, in 48.8 and 47.6% of cases. No breathing difficulties were reported. Streptococcus pyogenes was the most frequently identified microorganism. The average diameter of the collections from patients treated surgically as first-line therapy (group C) was significantly larger than that of the patients treated with antibiotics (group A) (27.89 mm vs. 18.73 mm, respectively, p = 0.0006). All the patients who required surgery despite 48 h of appropriate antibiotic therapy (group B) had collections with diameters greater than or equal to 15 mm. There was no significant difference between the groups concerning hospitalization duration. CONCLUSION: Exclusive medical treatment is associated with a high cure rate, mainly for collections with small diameter. We recommend special attention to patients treated with first-line exclusive intravenous antibiotic therapy and with a collection diameter greater than or equal to 15 mm.

[Clinical analysis of lateral cervical approach in the treatment of cervical lymphatic tuberculosis complicated with parapharyngeal space abscess].

Objective:To investigate the clinical effect of lateral cervical approach in the treatment of cervical lymphatic tuberculosis complicated with parapharyngeal space abscess. Methods:A total of 10 patients with cervical lymph node tuberculosis complicated with tuberculous abscess in parapharyngeal space were treated. Surgery was performed using a transcervical approach. The operation time and blood loss were recorded. The level of ESR, C-reactive protein（CRP）, VAS score and the rating of Kubota drinking test before and 2 weeks after operation were compared. The incision healing, symptoms of tuberculosis poisoning, and the CT findings of the cervical lesions were compared before operation, 2 weeks after operation and at the last follow-up. Results:The operation time ranged from 65 to 130 min with an average of （99.00±21.45） min. The intraoperative blood loss ranged from 100 to 250 mL with an average of （155.00±43.78） mL. The average pre-and post-operative level of ESR was （67.60±21.94） mm/1h and （30.30±13.76） mm/1h, respectively（U=5.500, P<0.01）; The average pre-and post-operative level of CRP was （69.70±31.13） mg/L and （42.40±19.70） mg/L, respectively（U=22.500, P<0.05）; The average pre-and post-operative VAS score was （5.60±1.26） points and （2.50±1.27） points, respectively（U=4.500, P<0.01）. As for Kubota drinking test, the rating was between 1-2 two weeks postoperatively. After relieving the compression, there was no obvious choking and coughing in drinking water. During the follow-up period （range: 6-24 months）, the surgical wound healed completely, and the symptoms of systemic tuberculosis poisoning disappeared. No obvious residual cavity or effusion was found in the parapharyngeal space by CT examination, nor was any protruding tissue in oropharynx. The edema of soft tissue surrounding the operational area disappeared, and the enlarged lymph nodes were significantly reduced. No sign of liquefaction, necrosis, suppuration or recurrence was observed. Conclusion:Surgery using transcervical approach effective in treating cervical lymph node tuberculosis with parapharyngeal space abscess.

Different types of dysphagia alleviated by the chin-down position.

OBJECTIVE: Retrospective videofluoroscopic swallowing study (VFSS) evaluations of pharyngeal swallowing were used to evaluate the types of dysphagia alleviated by the chin-down maneuver. MATERIALS AND METHODS: The study population consisted of 64 patients who underwent VFSS evaluations during neutral and chin-down maneuvers presenting specifically penetration or aspiration. The assessment of the VFSS movie clips of each maneuver was performed using parameters of the Modified Barium Swallow Impairment Profile (MBSImP) and the presence and degree of airway invasion(PDAI) by three blinded raters in the following five subcategorized groups, 1. patietns presenting penetration or aspiration during swallow 2. after swallow, patients of 3. head and neck, 4. digestive and 5. neuromuscular disorders, respectively. The scores registered for the two maneuvers were statistically compared. Additionally, we examined statistically which factors had the impact on the improvement of the PDAI using fisher's exact test. RESULTS: Compared with the neutral position, PDAI, pharyngeal constriction, anterior hyoid movement, pharyngeal constriction, laryngeal elevation, laryngeal closure, upper esophageal sphincter opening, initiation of the pharyngeal swallow, and pharyngeal clearance in pyriform sinus were significantly (p < 0.01-0.05) improved with the chin-down maneuver. In a subcategory comparison with group 1, 3 and 4, the PDAI improved significantly (p < 0.01) with the chin-down maneuver, in which laryngeal elevation and laryngeal closure had statistically the impact (p < 0.01-0.05) on improvement of PDAI. CONCLUSION: The chin-down maneuver was most effective in improving swallow function when the impairment included penetration and aspiration during swallow caused by inadequate laryngeal elevation and laryngeal closure.

Microbiology of parapharyngeal abscesses in adults: in search of the significant pathogens.

We aimed to describe the microbiology of parapharyngeal abscess (PPA) and point out the likely pathogens using the following principles to suggest pathogenic significance: (1) frequent recovery, (2) abundant growth, (3) growth in relative abundance to other microorganisms, (4) percentage of the isolates recovered in both absolute and relative abundance, (5) more frequent recovery in PPA pus compared with tonsillar surface and tissue. Comprehensive bacterial cultures were performed on specimens obtained from adult patients (n = 60) with surgically verified PPA, who were prospectively enrolled at five Danish ear-nose-throat departments. The prevalent isolates (in PPA pus) were unspecified anaerobes (73%), non-hemolytic streptococci (67%), Streptococcus anginosus group (SAG) (40%), Corynebacterium spp. (25%), Neisseria spp. (23%), Fusobacterium spp. (22%), Fusobacterium necrophorum (17%), Prevotella spp. (12%), and Streptococcus pyogenes (10%). The bacteria most frequently isolated in heavy (maximum) growth were unspecified anaerobes (60%), SAG (40%), F. necrophorum (23%), and Prevotella spp. (17%). The predominant microorganisms (those found in highest relative abundance) were unspecified anaerobes (53%), SAG (28%), non-hemolytic streptococci (25%), F. necrophorum (15%), S. pyogenes (10%), and Prevotella spp. (10%). Four potential pathogens were found in both heavy growth and highest relative abundance in at least 50% of cases: F. necrophorum, Prevotella spp., SAG, and S. pyogenes. SAG, Prevotella spp., F. necrophorum, S. pyogenes, and Bacteroides spp. were recovered with the same or higher frequency from PPA pus compared with tonsillar tissue and surface. Our findings suggest that SAG, F. necrophorum, Prevotella, and S. pyogenes are significant pathogens in PPA development.

Lymphoma with superimposed tuberculosis and fungal infection mimicking parapharyngeal abscess complicated with recurrent neurocardiogenic syncope: a case report.

INTRODUCTION: Lymphoma of parapharyngeal space (PPS) is a rare condition. The clinical presentations may vary and often masquerades as infection or an inflammatory condition. A misdiagnosis will lead to a delay in treatment of the disease. Due to the complex anatomy of PPS, any attributed pressure from masses can lead to a life-threatening event such as cardiac syncope. CASE REPORT: We report a rare case of PPS B-cell non-Hodgkin lymphoma with superimposed Tuberculosis (TB) and fungal infection that presents with several episodes of syncope and hemodynamic depression. DISCUSSION: The clinical entities in PPS lesions syncope and its associated syndromes, pathophysiology, and differential diagnosis together with possible managements are further discussed.

The usefulness of abscess tonsillectomy followed by intraoral drainage for parapharyngeal abscess concomitant with peritonsillar abscess in the elderly.

Parapharyngeal abscess (PPA) may cause life-threatening complications and peritonsillar abscess (PTA) and tonsillitis frequently precede PPA. The optimal management of PPA caused by PTA has been the subject of debate with respect to the surgical approach. We present three cases of PPA concomitant with PTA in elderly patients. In two cases, the abscesses in parapharyngeal space were drained by abscess tonsillectomy followed by intraoral incision of the tonsillar bed. On the other hand, the third case did not undergo abscess tonsillectomy because of his refusal of surgery and needed extraoral drainage after the aggravation of PPA. Based on the experience of those three cases, it was suggested that abscess tonsillectomy followed by intraoral incision of the tonsillar bed might be a useful surgical approach for the drainage of PPA concomitant with PTA, especially in elderly patients.

Is vessel narrowing secondary to pediatric deep neck space infections of clinical significance?

INTRODUCTION: Pediatric deep neck space infections (DNSI) may cause internal jugular vein and/or carotid artery narrowing. Radiologists and otolaryngologists are often queried by emergency room providers and pediatricians with regards to the clinical significance when this radiographic finding is noted. There are often questions raised about need for further imaging, anticoagulation and overall management strategy. There is limited data to support our answers to these questions. This study investigated the clinical significance of vessel narrowing of the internal jugular vein and carotid artery in the setting of DNSI in children. METHODS: 208 patients over a 10 year period were reviewed in retrospective fashion. CT scans reports were evaluated for vessel narrowing, and clinical outcomes were analyzed. RESULTS: This study found that nearly half (44.7%, 93 of 208) of pediatric DNSIs reviewed showed evidence of either carotid and/or internal jugular vein narrowing. There was no significant difference in vascular complications in those with vessel narrowing and those without (p = 0.09). There were no observed neurologic complications in either group. CONCLUSIONS: Vessel narrowing is a very common finding in pediatric DNSI. Vascular complications are very rare, and importantly no patients had neurologic complications in either group (vessel narrowing or not). We found no evidence to support more aggressive surgical management, getting further imaging, starting anticoagulation, nor changing overall management strategy for patients based solely to the finding of vessel narrowing in DNSI.

Isolated parapharyngeal cold abscess in a 9-year-old boy.

Tuberculous adenitis presenting as an isolated cold abscess in the parapharyngeal space is very uncommon and has not been reported in the paediatric age group; presentation as a retropharyngeal abscess, however, is well known. Nine-year-old boy with a progressively increasing swelling on the right side of the neck for 2 months was referred with a clinical diagnosis of neuroblastoma. Surgical exploration of the parapharyngeal space by needle aspiration yielded a cheesy material and Mycobacterium tuberculosis was detected by DNA TB PCR. Tuberculosis should always be considered in the differential diagnosis of a cervical swelling in a child.

Abcessos parafaríngeos na criança: estudo retrospectivo de 5 anos / Parapharyngeal abscess in children: five year retrospective study

Os abcessos laterofaríngeos e retrofaríngeos são infecções potencialmente fatais, designadamente na criança. Objetivo: Revisão de agentes etiológicos, achados clínicos e de exames de imagem de abcessos laterofaríngeos e retrofaríngeos em crianças, assim como de resultados e complicações do tratamento através de uma abordagem cirúrgica trans-oral. Material e método: Estudo retrospectivo abrangendo 11 crianças, internadas nos últimos 5 anos num hospital universitário terciário, com o diagnósticos de abcesso laterofaríngeo (n = 8) e retrofaríngeo (n = 3), com idades variando entre 0 e 12 anos. Os processos clínicos e exames de imagem foram revistos. Resultado: A idade média de apresentação foi de 3.3 anos de idade. Alterações da mobilidade cervical(64 por cento) e odinofagia(55 por cento) foram os sintomas mais frequentes. Febre(64 por cento), rigidez cervical(64 por cento), abaulamento da parede faríngea(55 por cento),massa cervical(55 por cento) e linfadenopatias(36 por cento) foram os achados clínicos mais frequentes. Todos os doentes foram submetidos a drenagem cirurgia por via trans-oral nas primeiras 48 horas após a admissão hospitalar. Cerca de 82 por cento dos doente apresentaram melhoria do quadro clinico após 48 horas e todos após 72 horas, sem quaisquer complicações. Conclusão: Considerando os bons resultados e a baixa taxa de complicações, o presente estudo sugere que uma antibioterapia sistémica associada a uma intervenção cirúrgica atempada parece ser uma opção válida no tratamento destes abcessos.

Lateropharyngeal and retropharyngeal abscesses are potentially life threatening infections in children AIM: To review the etiologic, clinical, and imaging signs of lateropharyngeal and retropharyngeal abscesses in children as well as treatment-outcomes and complications using a surgical trans-oral approach. Method: Retrospective analysis of 11 children, hospitalized in the last 5 years, with a diagnosis of lateropharyngeal (n = 8) and retropharyngeal (n = 3) abscesses, ages ranging from 0 to 12 years old. Charts and CT scans were reviewed. Result: The average age of presentation was 3.3 years. Neck stiffness (64 percent) and odynophagia (55 percent) were the most common symptoms. Fever (64 percent), stiff neck (64 percent), bulging of the oropharyngeal wall (55 percent), mass in the neck (55 percent) and lymphadenopathy (36 percent) were the most prevalent physical findings. All these patients were submitted to surgical drainage using a trans-oral approach in the first 48 hours after admission. About 82 percent of the patients showed improvement after 48 hours, and 100 percent after 72 hours, without any complications. Conclusion: Based on the good clinical outcomes and low incidence of complications, the present study suggests that antibiotic therapy complemented with a timely surgical treatment, is a valid treatment option in refractory parapharyngeal abscesses.

Clinical versus computed tomography evaluation in the diagnosis and management of deep neck infection

CONTEXTO: Infecções profundas do pescoço têm um potencial alto para complicações graves e morte, se não corretamente diagnosticadas e tratadas. A diferença entre resultados de avaliação clínica e tomográfica pode demonstrar que a avaliação clínica isolada subestima a extensão de doença, o que pode conduzir a tratamento conservador e a pior prognóstico. OBJETIVO: Comparar achados clínicos à tomografia computadorizada de pescoço em relação aos espaços cervicais envolvidos e determinar as características clínicas e radiológicas principais associadas com infecção de espaço profundo de pescoço. TIPO DE ESTUDO: Estudo retrospectivo não randomizado. LOCAL: Departamento de Otorrinolaringologia - Cabeça e Pescoço, Universidade Estatal de Campinas, Brasil, um centro universitário, terciário. MÉTODOS: Foi avaliado prontuário médico de 65 pacientes com infecções profundas de pescoço. Foram analisados idade, gênero, queixas clínicas, exames físicos, resultados de raios-x e tomografia computadorizada, microbiologia, tratamento e resultados. Foram avaliados os sinais clínicos e sintomas, estratificados em ordem de freqüência. A freqüência de espaços cervicais profundos envolvidos nesta infecção também foram avaliados clínico e tomograficamente. Todos resultados clínicos e tomográficos foram comparados com a observação cirúrgica em relação aos espaços cervicais afetados por infecção. RESULTADOS: Os resultados clínicos mais freqüentes foram inchaço cervical, dor local, eritema cutâneo local e aumento localizado de temperatura. O local mais afetado de acordo com a avaliação física foi o triângulo de submandibular (49,2%), mas, à tomografia computadorizada cervical, foi o espaço látero-faríngeo (65%). Mais de um espaço cervical profundo foi acometido, de acordo com a tomografia computadorizada cervical, em 90% dos pacientes, como demonstrado pela extensão do edema e aumento de captação de tecidos moles, e em geral apenas um espaço à avaliação clínica isolada. DISCUSSAO: Os sintomas clínicos mais freqüentes das infecções cervicais profundas foram dor cervical, aumento de volume cervical e febre. Sinais importantes da tomografia computadorizada, para avaliação desta infecção, foram aumento de captação de contraste em tecidos moles do pescoço e edema. O espaço profundo do pescoço mais afetado pela infecção foi o laterofaríngeo, pela tomografia computadorizada do pescoço. O espaço...

Abscesos cervicales profundos: presentación y manejo médico-quirúrgico, en el Hospital Regional Honorio Delgado de Arequipa, de 1985 a 1996

Se realizó un estudio de 26 pacientes con el diagnóstico de absceso cervical profundo, quienes fueron vistos entre los años de 1985 a abril de 1996. La edad fluctuó entre un rango de 1 a 79 años, siendo el promedio de 25 años. Hubo predominio del sexo femenino sobre el masculino (18/8). Basados en la clínica y en los hallazgos operarios, estos abscesos fueron categorizados como angina de Ludwing (7 pacientes), absceso periamigdalino (15 pacientes), absceso laterofaríngeo (2 pacientes) o absceso periamigdalino y laterofíngeo simultaneamente (2 pacientes). El foco de origen más frecuente fue el odontogénico (42 por ciento), luego el faringo-amigdalino (31 por ciento), no se determinó la causa en el 4 por ciento. Los síntomas principales fueron la disfagia/odinofagia, la sensación febril, el dolor en la tumoración, el ardor de garganta, la disfonía, y el malestar general. En cuanto a los principales signos estos fueron la anormalidad orofaríngea, la tumoración cervical, la anormalidad dental, el trismus y la adenopatía cervical, principalmente. La temperatura al ingreso fluctuó en un rango de 36,3 a 39,8 ºC siendo el promedio de 37,8 ºC. El 71 por ciento de los pacientes recibieron algún tipo de antibiótico antes de ser hospitalizados. Los exámenes auxiliares más utilizados fueron el hemograma-hemoglobina, en donde el recuento leucocitario promedio fue de 11,345/mm3, y el 36 por ciento de los pacientes tubo leucocitosis con desviación izquierda. El gram y cultivo se realizó en pocos pacientes, en donde predominó el Stafilococo Aureos. El tratamiento médico se dió al 19 por ciento de los pacientes, y el tratamiento médico-quirúrgico al 81 por ciento de los pacientes y mala en el 19 por ciento. No hubieron fallecidos. Se presentaron complicaciones en 6 pacientes (23 por ciento). Los resultados fueron comparados con otros reportes.
