RESUMO
BACKGROUND: Acute suppurative thyroiditis is a rare and potentially life-threatening disease. A few cases of acute suppurative thyroiditis associated with thyrotoxicosis have been reported in adults. We report a case of acute suppurative thyroiditis that was associated with thyrotoxicosis. CASE PRESENTATION: We report the case of a 49-year-old Iranian female presented with a painful neck swelling for a week. Computed tomography showed a well-defined gas-filled collection in the left thyroid lobe with an enhancing margin. The patient underwent two-phase surgery, first left thyroid abscess drainage and then total thyroidectomy. The result of histopathology examination was multinodular goiter with abscess formation without malignancy. CONCLUSION: Abscess formation and thyrotoxicosis is a very rare condition that occurs at the same time in acute suppurative thyroiditis. Despite antibiotic therapy being the first line of treatment, surgery is also required when antibiotic therapy fails.

Acute suppurative thyroiditis is an uncommon disorder caused by a bacterial infection, usually presenting with normal thyroid function. It is a serious condition that requires a prompt diagnosis and treatment with antibiotics and supportive measures. A 62 years-old female presented with a painful cervical induration and odynophagia a week after a fish bone had been removed from her pharynx. She was febrile, and tachycardic and, on physical examination, a painful thyroid mass was detected. High inflammatory parameters and thyrotoxicosis were confirmed: thyroid stimulating hormone (TSH) < 0.01 mIU/L (normal range [NR] 0.27-4.2); free thyroxine (FT4) 3.86 ng/dL (NR 0.9-1.7) and anti-TSH receptor antibodies (TRABs) 5.3 U/L (NR < 1.5). Thyroid scintigraphy showed a diffuse uptake of the thyroid parenchyma suggesting Graves disease. Cervical ultrasonography revealed an abscess of the left thyroid lobe of 36 × 36 mm and fine needle aspiration biopsy (FNAB) with partial drainage was performed. Staphylococcus aureus and Streptococcus viridans were isolated, and directed antibiotic therapy was started. Clinical improvement was observed as well as a decrease of inflammatory parameters and the patient was discharged after 9 days of hospitalization. Eighteen days after discharge, thiamazole was initiated due to persistent thyrotoxicosis. Complete resolution of the abscess was documented within 6 months and the patient became euthyroid under thiamazole one year after initial presentation. To our knowledge, this is the third case reporting an association between acute thyroiditis and Graves disease. Furthermore, this is the first case detailing the simultaneous diagnosis of acute suppurative thyroiditis caused by a foreign body and Graves disease.

BACKGROUND: Pyriform sinus fistulas (PSFs) are rare congenital anomalies of the third or fourth brachial pouch. Dyspnea is reportedly secondary to compression by a neck mass. However, hoarseness, as the first symptom of PSF, has not yet been reported. CASE PRESENTATION: This report describes an 11-year-old girl presenting with hoarseness as the first symptom of PSF. Hoarseness occurred 2 days prior to admission. On admission, she had fever, hoarseness, and an elastic soft mass on her left anterior neck. Contrast-enhanced computed tomography of the cervical region demonstrated an abscess partially infiltrating the thyroid gland and an air pocket near the pyriform sinus. Pharyngoscopy revealed swelling of the left arytenoid region, with purulent retention. The left vocal cord was swollen but not paralyzed. Additionally, the laboratory data indicated thyrotoxicosis. Suspecting a PSF infection, parenteral treatment with cefotaxime and dexamethasone was initiated. On the following day, the hoarseness disappeared, and the fever resolved. Four weeks after onset, the thyroid hormone levels returned to the normal range, and a barium esophagogram revealed residual contrast in the left pyriform sinus, leading to a diagnosis of PSF. CONCLUSION: PSF presenting with hoarseness as the first symptom in patients should be considered.

A 42-year-old woman inadvertently discovered a neck mass, which caused pain. Initially, she was treated with antibiotics at a local clinic; however, this treatment did not alleviate the symptoms. She visited the authors' outpatient clinic for further treatment and underwent thyroid ultrasonography, which revealed a mixed echo nodule. On day 4 after admission, surgery was performed to remove the diseased thyroid tissue and levofloxacin (0.4 g/day) was infused. Bacterial culture confirmed infection with Clostridium perfringens. Subsequently, the treatment was switched to ceftriaxone sodium (2 g/day) according to the results of the drug sensitivity test. Following treatment, the patient recovered fully and was discharged. She was then followed up with after discharge. Ultrasonography, laboratory testing and clinical manifestations did not indicate obvious abnormalities.

Isolated thyroid abscess is a rare entity in early childhood. Among thyroid disorders, thyroid abscess or acute suppurative thyroiditis constitutes about 0.7%-1% of all cases. The thyroid gland is normally resistant to infections due to its well-enveloped capsule, rich blood supply, and high iodine content.A child presented with tender neck swelling accompanied by fever for 3 days. Ultrasound of the neck showed features suggestive of left parapharyngeal abscess. Laboratory parameters including thyroid function test were within normal limits. Contrast-enhanced CT of the neck was done and showed an isolated thyroid abscess with no other abnormalities. The patient was started on intravenous antibiotics followed by incision and drainage of the abscess. The child improved symptomatically. This report discusses the differential diagnosis and management of this rare entity.

Acute suppurative thyroiditis is a rare and potentially life-threatening cause of thyroid inflammation requiring prompt recognition and management. There are few reported cases of thyrotoxicosis due to acute suppurative thyroiditis. We are reporting the case of a 9-year-old boy who presented to the emergency room with fevers, neck pain and swelling, night terrors, and emotional lability. He was hemodynamically stable with initial lab work remarkable for neutrophilia without leukocytosis, elevated inflammatory markers, and hyperthyroidism. Imaging of the neck revealed a heterogenous collection in the region of the left thyroid concerning for suppurative thyroiditis and adenitis. He was admitted to the hospital and initiated on intravenous antibiotics. Given lack of significant improvement in pain, he was taken to the operating room for drainage on hospital day 4 with remarkable clinical improvement in pain. He was discharged on oral antibiotics. Lab work obtained on postoperative day 15 showed resolution of hyperthyroidism and decreasing inflammatory markers. Subsequent imaging following resolution of the acute illness did not reveal any anatomic abnormality that may have predisposed him to developing acute suppurative thyroiditis. Thyrotoxicosis as a complication of acute suppurative thyroiditis is a rare occurrence, and is thought to be due to the release of preformed thyroid hormone from damaged thyroid follicles. The thyrotoxic state is often transient and resolves with appropriate management of acute suppurative thyroiditis. This complication is important to recognize, as failure to appropriately diagnose and treat acute suppurative thyroiditis can lead to poor outcomes, such as airway compromise and death.

BACKGROUND: Accidental ingestion of fish bone is a common cause of otolaryngological emergency. Migration of the ingested bone into the thyroid gland, however, occurs very rarely. The associated clinical presentation, symptoms and duration of discomfort are also highly variable between patients and can be diagnostically challenging. CASE PRESENTATION: Here, we report the case of a 71-year-old female patient presenting with an ingested fish bone that migrated into the right thyroid lobe as a rare cause of suppurative thyroiditis with the clinical features of sepsis. We outline the diagnostic approach, peri- and intraoperative management as well as complications. It is proposed that besides endoscopy, imaging methods such as ultrasound or computed tomography may be necessary to verify the diagnosis and location of an ingested fish bone. Prompt surgical removal of the foreign body and resection of the infectious focus is recommended to minimize the risk of local inflammation, recurrent nerve lesions and septic complications arising from the spread of infection. CONCLUSION: Fish bone migration into the thyroid gland is an extremely rare event, the successful detection and surgical management of which can be achieved through a careful interdisciplinary approach.

BACKGROUND: Third and fourth branchial anomalies are rare, accounting for less than 10% of all branchial anomalies. The piriform fossa sinus tract (PFST) typically presents with left-side suppurative thyroiditis, although it can present earlier in neonates as a non-inflamed cystic neck mass. PFST poses a considerable diagnostic challenge with variable clinical and imaging features, leading to long delays to definitive diagnosis and appropriate management. OBJECTIVE: To analyse the patterns of presentation and imaging findings in children with PFST, with a particular focus on neonatal presentation. MATERIALS AND METHODS: This was a retrospective review of the clinical presentation, imaging findings and management in 16 cases of PFST presenting to our tertiary children's hospital between 2003 and 2018. Cases were identified by medical records and picture archiving and communication system (PACS) search using relevant International Classification of Diseases (ICD)-10 coding. RESULTS: Age at presentation ranged from prenatal to 16 years, with a male-to-female ratio of 2:1. All patients presented with neck swelling. Thirteen patients (81%) had suppurative thyroiditis at initial presentation. Two patients had severe thyroiditis/mediastinitis that required intensive care unit admission. Three neonates presented with noninfected, asymptomatic large cystic neck masses; two of these were detected prenatally and misdiagnosed as lymphatic malformations with subsequent spontaneous clinical resolution that later represented with evidence of PFST. The PFST was on the left side in 15/16 (94%) patients. All patients had neck imaging before definitive diagnosis. Imaging studies included radiographs, ultrasound, computed tomography, magnetic resonance imaging and barium esophagram studies. No single modality was diagnostic of PFST in all patients. Seventy-five percent of patients had multimodal imaging before diagnosis. All PFSTs were confirmed by endoscopic visualisation. Management of PFST was by endoscopic cauterisation in 13 patients and open surgery in 2. One patient did not require surgical correction. CONCLUSION: Our study highlights the complex nature of PFST. The anomaly is uncommon, has variable clinical and imaging features and may have a lengthy, complicated course if not considered at initial presentation. An episode of suppurative thyroiditis in a child should prompt investigation for PFST. We describe atypical presentations with cystic masses in neonates that appear to resolve but represent later as typical clinical features of PFST.

SUMMARY Acute suppurative thyroiditis (AST) is a rare but potentially life-threatening thyroid disease with a high mortality if left untreated. Thus, differentiation from other thyroid disorders is highly important in clinical practice. A 22-year-old male patient was admitted to a tertiary care hospital with cervical pain, palpitations, thyrotoxicosis, and an inhomogeneously enlarged right thyroid lobe. In view of the clinical findings, subacute thyroiditis (SAT) was suspected and treatment with glucocorticoids was started. After initial amelioration, the patient developed cervical erythema, fever, and recurrent pain. A CT scan showed extensive phlegmonous inflammation and abscess formation, suggestive of AST. We started immediate empiric antibiotic therapy and performed surgical drainage of the abscess formations. Subsequently, the patient developed hypoxic respiratory failure, leading to ICU admission and intermittent need for non-invasive ventilation. Blood and abscess cultures were positive for Streptococcus anginosus. If left untreated, AST represents a potentially life-threatening disease. Thus, in clinically doubtful cases, liberal further assessment by means of cervical CT scans or fine needle aspiration biopsy are strongly advised.

OBJECTIVE: To demonstrate our experience in treating pyriform fossa sinus tracts (PFST) using a novel technique of endoscopic cauterisation of the pyriform fossa sinus opening combined with injection of sodium carboxymethylcellulose gel (VoiceGel) lateral to the tract to encourage tight closure. METHODS: Over a 48-month period, we used this technique on 11 patients who were diagnosed with PFST at BC Children's Hospital, a tertiary paediatric centre in Vancouver, BC, Canada. RESULTS: The 11 patients included 8 males and 3 females, and mean age at presentation was 69 months (range 22-108 months). Mean time from beginning of symptoms till diagnosis was 15 months (range 12-22 months). Ten PFST were on the left side of the neck and one on the right. Nine patients presented with recurrent neck infections and two had suppurative thyroiditis. All patients had endoscopic cauterisation of their PFST opening combined with injection of carboxymethylcellulose lateral to the sinus tract to cause tract collapse. Mean follow up was 15.8 months (range 8-24). All patients are asymptomatic without recurrence at the last follow-up visit. No post-operative complications were reported. CONCLUSIONS: Endoscopic management of paediatric PFST combined with the injection of sodium carboxymethylcellulose gel lateral to the sinus tract appears to be a safe and effective treatment option for PFST.

Acute suppurative thyroiditis is an infectious disease, uncommon in children, caused by various microorganisms, being bacteria the most frequently involved. The typical presentation includes the appearance of a tumor in combination with signs of swelling in the anterior aspect of the neck, which is painful on palpation and is associated with warmth and erythema. It usually moves with swallowing and the patient can suffer fever, dysphagia or dhysfonia. In children, congenital anomalies can lead to the gland's infection, and the surgical excision of them is important to prevent recurrency. A quick diagnosis, based on clinical manifestations and imaging studies, is necessary to install an adequate antibiotic treatment. We present the case of a 3-year-old patient, who was previously healthy, with a painful left cervical tumor associated with fever. During the hospitalization, we reached the diagnosis of acute suppurative thyroiditis caused by an underlying pyriform sinus fistula.
La tiroiditis aguda supurada es una entidad poco frecuente en pediatría; de origen infeccioso, cuya etiología más frecuente es bacteriana. Su presentación típica en niños es la aparición de una tumoración en la cara anterior del cuello, con signos de flogosis, dolorosa, caliente y eritematosa, que excursiona con la deglución, y puede o no estar acompañada de fiebre, disfagia o disfonía. En niños, las anomalías congénitas, principalmente la fístula del seno piriforme, predisponen a la infección de la glándula, por lo que es importante la resolución quirúrgica del defecto anatómico para prevenir las recurrencias. El diagnóstico rápido, basado en la clínica y los estudios por imágenes, es importante para comenzar en forma temprana con un tratamiento antibiótico adecuado. Se presenta una paciente de 3 años, previamente sana, con tumoración cervical izquierda dolorosa y asociada a fiebre. Durante la internación, se arribó al diagnóstico de tiroiditis aguda supurada secundaria a fístula de seno piriforme.

BACKGROUND: Acute suppurative thyroiditis through the congenital pyriform sinus fistula (PSF) often recurs if the fistula is not resected. Although endoscopic chemo-cauterization (ECC) to obliterate the orifice of the fistula is less invasive than open fistulectomy, it may require repeated treatments. We recently adopted an endoscopic diode laser-cauterization (ELC) system with the intention of improving treatment outcomes in PSF. Here, we describe ELC and compare the outcomes of these three modalities. METHODS: We evaluated 83 patients with PSF who underwent treatment between 2007 and 2018 at Kuma Hospital, a tertiary thyroid treatment hospital. ECC and ELC were implemented in 2007 and 2015, respectively. Patients who were ineligible for the endoscopic procedures underwent open fistulectomy. Barium swallow studies and computed tomography scan under a trumpet maneuver were performed after treatment to evaluate obliteration or removal of the fistula. RESULTS: In total, 70 of the 81 (86%) patients who underwent barium swallow studies after the first treatment achieved obliteration or removal of the fistula. The success rates for open fistulectomy, ECC, and ELC were 100% (9/9), 83% (49/59), and 100% (13/13), respectively. ECC and ELC had significantly shorter operative times and lower blood loss than open fistulectomy. Insufficient opening of the mouth was the major reason for converting endoscopic procedures to open fistulectomy. CONCLUSIONS: ELC may yield superior outcomes and is therefore the optimal treatment modality for PSF. However, it is still associated with certain limitations. Thus, treatment selection remains dependent on the shape and size of the PSF and the mouth opening of the individual patient.

Pyriform sinus fistula is uncommon and easily misdiagnosed. Most reported cases occur in children and are associated with either acute suppurative thyroiditis or deep neck infection. Asymptomatic pyriform sinus fistula is difficult to diagnose because it can manifest as an incidental thyroid nodule with highly suspicious malignant features on ultrasonography. The patient was a 41-year-old man with asymptomatic thyroid nodules incidentally detected on ultrasonography. Surgery was performed under the suspicion of thyroid cancer. Pathology findings revealed multiple cystic walls lined by ciliated columnar cells with stratified squamous epithelial cysts in a background of inflammatory and lymphoid cells. Barium swallow examination performed 2 weeks later revealed a sinus tract measuring 1.8 cm that arose from the apex of the left pyriform sinus. The diagnosis and management of pyriform sinus anomalies are challenging. The majority of physicians, including some otolaryngologists, lack an understanding of the disease, which should be considered one of the important differential diagnoses of neck masses. Barium swallow examination, ultrasonography, computed tomography, and laryngoscopy are useful to diagnose this condition.

OBJECTIVE: Acute suppurative thyroiditis (AST) is a rare but potentially fatal condition which can initially be difficult to distinguish from the more common subacute thyroiditis (SAT). We aim to update understanding of this medical emergency. DESIGN: A systematic review over the past 20 years was performed on the epidemiology, clinical features, investigations, management and outcomes of AST. All full-text cases of microscopy or culture- proven AST in the English literature were included. RESULTS: 200 cases of AST have been described in 148 articles from January 2000 - January 2020. Bacterial AST is most common, often presenting with neck pain (89%) and fever (82%). Immunosuppression and pyriform sinus fistula are the most common causes, most often due to gram-positive aerobes. Transient hyperthyroidism is common (42%). Aspiration and antibiotics are becoming a more common treatment. Overall mortality was 7.8%. Tuberculous and fungal AST are less likely to present with fever and neck pain. Fungal AST is more common in immunosuppressed individuals (31%) and has a high overall mortality (33%). Tuberculous AST is more common in TB endemic areas. CONCLUSION: The symptoms and signs of AST commonly overlap with SAT and initially can be hard to diagnose. AST can be rapidly morbid or even fatal. Clinicians need to consider AST when they assess patients with thyroiditis who are systemically unwell, have high fever, high white cell count and c-reactive protein, tender neck and abnormal neck imaging. An investigative and treatment strategy is described based on a systematic review of the literature.

OBJECTIVE: The aim of this study was to determine if microbiological cultures can guide management of suppurative thyroiditis. DESIGN: This study is a retrospective case series set in 2 tertiary care academic hospitals. METHODS: The microbiological cultures from patients with suppurative thyroiditis who underwent incision and drainage from July 2004 to June 2018 were reviewed. Those who had confirmed pyriform sinus tracts and underwent surgical intervention were included in the study. RESULTS: Fifteen patients satisfied the criteria for inclusion. All had confirmed pyriform sinus tracts and underwent successful intervention. Endoscopic cautery was the most common intervention followed by complete open excision. Five cultures grew alpha Streptococcus, 6 had Eikenella, and 4 Prevotella. Combinations of Eikenella + Prevotella were seen in 3, and 1 sample had all 3 bacteria. Two cultured methicillin-susceptible Staphylococcus aureus alone. One culture was sterile. CONCLUSIONS: The presence of oral flora in an intrathyroidal abscess is confirmatory evidence of a pyriform sinus tract. Further investigations are not needed, and early definitive intervention can be planned.

Head and neck infections can spread to nearby structures, compromising the airway and progressing to life-threatening events. Pediatric head and neck infections can be difficult to recognize; emergency clinicians must know the signs and symptoms of head and neck infections for early diagnosis and urgent management in order to prevent complications and decrease hospitalization rates. This issue reviews presenting signs and symptoms of pediatric head and neck infections, discusses when diagnostic studies are indicated, and offers evidence-based recommendations for management. Conditions reviewed include mastoiditis, sinusitis, Ludwig angina, peritonsillar abscess, retropharyngeal abscess, Lemierre syndrome, and acute suppurative thyroiditis.
