Thyrotoxicosis as a rare presentation in acute suppurative thyroiditis: a case report.

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.

Aspiration with or without lavage in the treatment of acute suppurative thyroiditis secondary to pyriform sinus fistula

ABSTRACT Objective There is currently no consensus regarding the optimal management of acute suppurative thyroiditis (AST) secondary to pyriform sinus fistula (PSF). To investigate the benefits and adverse events of aspiration with or without lavage for the treatment of AST secondary to PSF. Subjects and methods This was a retrospective analysis of consecutive patients with AST secondary to PSF who were admitted at the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University between August 2012 and December 2018. Clinical information, procedural data, and imaging data were analyzed. Results Seven patients (five women; mean age, 16.9 ± 6.3 years; range, 8-26 years) were included. The patients most presented with anterior neck pain and swelling (n = 7), fever (n = 7), or odynophagia (n = 5). Six cases of AST occurred on the left side of the thyroid and 1 on the right. All patients had thyroid abscess. AST was diagnosed by ultrasound-guided needle aspiration cytology in all cases. PSF was diagnosed during the inflammatory stage in five patients and during the quiescent stage in two. All patients were treated with empiric antibiotics. Needle aspiration without lavage was performed in three cases. Needle aspiration with lavage was performed in four cases. Repeat aspiration was performed in three cases. All patients recovered completely, with no procedure-related complications. During 18.3 ± 7.8 months of follow-up, AST recurred in one case. Excision of the PSF was performed in another case. Conclusion Ultrasound-guided aspiration with or without lavage had a good treatment effect and without adverse events for the management of AST secondary to PSF.

Acute suppurative thyroiditis with thyroid abscess in adults: clinical presentation, treatment and outcomes.

BACKGROUND: Abscess in the thyroid gland is a rare but severe infectious disease. The condition can have anatomic or iatrogenic underlying causes. If untreated it could be fatal. Pathogens vary considerably. Treatment is intravenous antibiotics, drainage, and sometimes surgery. METHODS: The electronic medical records of all adult patients with acute thyroiditis 2003-2017 treated at the Karolinska University Hospital (catchment area 2 million) in Sweden were systematically reviewed. RESULTS: Five patients were found in the catchment area. One patient from another region but known to us was also included. Thus, six patients (aged 28-73 years) were included in the study. Median length of hospital stay was 7.5 days (4-79 days). All were treated with antibiotics (intravenous n = 5, oral n = 1). Total antibiotic treatment duration was 13.5 days (10-41 days). Blood cultures were positive in three (streptococcus pneumonia, streptococci sanguineous, pepto streptococci), deep tissue culture in three (Escherichia coli, Candida, Hemophilic influenza) and no positive culture at all in two. Drainage was used in three patients. All patients recovered without recurrences. Surgery was performed twice in the acute phase in one. There was no recurrence during 7 years (3-12) of follow-up, but one patient died after three years (severe heart failure and pneumonia). CONCLUSION: Thyroid abscess in adults is extremely rare nowadays in the developed world. With prompt antibiotic therapy, drainage and in some cases thyroidectomy the prognosis seems favourable.

Management of thyroid gland abscess. / Manejo del absceso de la glándula tiroides.

BACKGROUND: Thyroid abscess or acute suppurative thyroiditis is an unusual clinical condition. We present our experience with cases attended over 41 years. MATERIALS AND METHODS: A retrospective study was performed on these patients reviewing their epidemiological characteristics and the diagnostic and therapeutic manoeuvres chosen for them all, as well as their clinical outcome. A group of 9 males and 5 females was studied, with ages ranging from 19 to 68 (mean of 40.6±15.4). These patients suffered 22 acute episodes, and 2 patients each had 4 episodes. RESULTS: Suppurative thyroiditis comprised 0.29% of the neck abscesses. Fine needle aspiration was performed in 13 cases to evacuate the collection and isolate the aetiological agent. Mycobacterium tuberculosis and Staphylococcus aureus were the most frequently identified. Nine patients underwent ultrasound and 7 computed tomography imaging studies. Surgery was the option for 10 patients, including drainage for 7, thyroidectomy for 4 and hemithyroidectomy for the remaining 2. Systemic or intralesional antibiotics and sclerosis of the gland were also carried out. Although one case presented with hyperthyroidism and thyrotoxicosis in the acute phase, definitive hypothyroidism was observed in 5 patients at 6 months following discharge. The rate of success was 100%. CONCLUSION: Thyroid gland suppuration is a very infrequent circumstance in neck pathology, and the options for its treatment are varied, from conservative to invasive techniques according to the microbial and radiologic findings.

Tiroiditis no-autoinmunes / Non-autoimmune thyroiditis

El término tiroiditis comprende un grupo de enfermedades de la glándula tiroides caracterizado por la presencia de inflamación, abarcando entidades autoinmunes y no-autoinmunes. Pueden manifestarse como enfermedades agudas con dolor tiroideo severo (tiroiditis subaguda y tiroiditis infecciosas), y condiciones en las cuales la inflamación no es clínicamente evidente, cursando sin dolor y presentando disfunción tiroidea y/o bocio (tiroiditis inducida por fármacos y tiroiditis de Riedel). El objetivo de esta revisión es aportar un enfoque actualizado sobre las tiroiditis no-autoinmunes cubriendo sus aspectos clínicos, diagnósticos y terapéuticos.

The term thyroiditis comprises a group of thyroid diseases characterized by the presence of inflammation, including autoimmune and non-autoimmune entities. It may manifest as an acute illness with severe thyroid pain (subacute thyroiditis and infectious thyroiditis), and conditions in which the inflammation is not clinically evident evolving without pain and presenting primarily thyroid dysfunction and/or goiter (drug-induced thyroiditis and Riedel thyroiditis). The aim of this review is to provide an updated approach on non-autoimmune thyroiditis and its clinical, diagnostic and therapeutic aspects.

Case of concurrent Riedel's thyroiditis, acute suppurative thyroiditis, and micropapillary carcinoma.

Riedel's thyroiditis (RT) is a rare chronic inflammatory disease of the thyroid gland. It is characterized by a fibroinflammatory process that partially destroys the gland and extends into adjacent neck structures. Its clinical manifestation can mask an accompanying thyroid neoplasm and can mimic invasive thyroid carcinoma. Therefore, diagnosis can be difficult prior to surgical removal of the thyroid, and histopathologic examination of the thyroid is necessary for a definite diagnosis. The concurrent presence of RT and other thyroid diseases has been reported. However, to our knowledge, the association of RT with acute suppurative thyroiditis and micropapillary carcinoma has not been reported. We report a rare case of concurrent RT, acute suppurative thyroiditis, and micropapillary carcinoma in a 48-year-old patient.

Subacute, silent, and postpartum thyroiditis.

Subacute, silent, and postpartum thyroiditis are temporary forms of thyroid dysfunction caused by thyroid gland inflammation. They classically present with a triphasic course: a brief period of thyrotoxicosis due to release of preformed thyroid hormone that lasts for 1 to 3 months, followed by a more prolonged hypothyroid phase lasting up to 6 months, and eventual return to a euthyroid state. However, the types and degree of thyroid dysfunction are variable in these disorders, and individual patients may present with mild or more severe cases of thyrotoxicosis alone, hypothyroidism alone, or both types of thyroid dysfunction.

Tireoidite supurativa aguda em paciente pediátrico / Acute suppurative thyroiditis in pediatric patient

A tireoidite supurativa aguda (TSA) é uma condição rara, potencialmente ameaçadora da vida, que acomete geralmente mulheres na idade adulta, sendo mais comum em pacientes com doença tireoideana pré-existente. Os autores apresentam o caso de uma paciente pediátrica, previamente hígida, com quadro clínico e exames complementares sugestivos de TSA durante sua internação no Hospital Universitário da Universidade Luterana do Brasil.

Acute suppurative thyroiditis (AST) is a rare life-threatening condition that usually affects women in adulthood, being more common in patients with pre-existing thyroid disease. The authors report the case of a previously healthy pediatric patient with clinical and laboratory tests suggestive of AST during her hospitalization at the University Hospital of the Lutheran University of Brazil.

Absceso tiroideo con fístula del seno piriforme: tres casos clínicos / Thyroid abscess with pyriform sinus fistulae: 3 clinical cases

Thyroid abscess is an infrequent, potentially life-threatening condition. It accounts for 0,1 to 0,7 percent of thyroid pathology, usually occurring in patients with preexisting disease of the gland or more commonly, associated to local anatomical defects, such pyriform sinus fistulae. Three cases of thyroid abscess in children are presented, in which no bacterial etiology was confirmed. Intravenous antibiotics were used, cefotaxime, cloxacillin or clindamicin. Recurrence was confirmed in 2 of them, and a pyriform sinus fistulae was demostrated by esophagogram.

El absceso tiroideo es un cuadro infrecuente y una emergencia endocrina potencialmente fatal. Representa el 0,1 a 0,7 por ciento de las patologías tiroideas. Habitualmente se produce en pacientes con patología preexistente de la glándula o más frecuentemente, asociado a defectos anatómicos locales, como una fístula del seno piriforme. Presentamos 3 casos de abscesos tiroideos en escolares. Recibieron tratamiento antibiótico endovenoso de amplio espectro, a pesar de lo cual dos de ellos recidivaron precozmente. En dos de ellos se demostró una fístula del seno piriforme con esofagograma que se manejó quirúrgicamente.

Thyroid abscess as a complication of bacterial throat infection.

Thyroid abscesses are rare complications of neck infections. We report the case of a teenager who developed increasing neck pain and swelling following treatment for a Streptococcus throat infection. Imaging demonstrated a complex fluid collection in the left thyroid lobe. Ultrasound guided aspiration was performed for diagnostic purposes, yielding purulent fluid that grew multiple bacterial species. Following initial antibiotic treatment, the patient underwent definitive surgical management. Underlying risk factors and imaging techniques will be reviewed.

Acute bacterial suppurative thyroiditis: a clinical review and expert opinion.

BACKGROUND: Acute suppurative thyroiditis (AST) resulting from a bacterial infection is an infrequent but potentially life-threatening endocrine emergency. Traditional management of this disease has been surgery in conjunction with targeted antibiotic therapy. Recent nonrandomized reports of small series have demonstrated good outcomes using less invasive approaches. No randomized clinical trials have been performed. Here, we provide a review of the literature and an approach to this problem based on expert opinion. METHODS: The literature was reviewed utilizing PubMed, and a representative case of AST was presented to a panel of experts. Endocrinology, surgery, and infectious disease experts responded to a series of questions regarding diagnosis, management, prognosis, and harm. RESULTS: Combining a broad spectrum of clinical expertise and the published literature, the authors suggest a clinical algorithm as a guide to management, addressing both diagnosis and acute and long-term management. CONCLUSIONS: Published studies indicate a trend toward less invasive management during active inflammation and infection and regarding definite therapy. Remaining questions are presented to foster an evidence-based approach to this disease. Ideally, future randomized, controlled trials will provide data to improve the therapy and outcome of AST.

Acute suppurative klebsiella thyroiditis: a case report.

Acute suppurative thyroiditis and thyroid abscess are extremely rare disorders. The most common pathogens causing acute suppurative thyroiditis are Gram-positive bacteria, including staphylococcal and streptococcal species. Thyroid abscess is mostly located in the left thyroid lobe. We report the case of a 75-year-old female patient with acute suppurative thyroiditis and right lobe thyroid abscess caused by Klebsiella spp. The patient had a firm, livid, hardly mobile cervical swelling. Axial computed tomography image showed soft-tissue swelling, an abscess in the right thyroid lobe and swelling of the thyroid gland. The diagnosis was established on a smear culture result. The patient was diabetic and had been operated on for goitre fifty years before. On indirect laryngoscopic examination, the patient was found to have right vocal cord paralysis. Infection and abscess resolved following surgical drainage and treatment with intravenous antibiotics, while the vocal cord paralysis persisted. Diabetes mellitus and previous thyroid surgery, in which sutures were used with unresorptive material, might have been the precipitating factors for the patient to acquire this unusual infection.

Suppurative thyroiditis in children: a management algorithm.

OBJECTIVE: To elucidate the etiology of suppurative thyroiditis in children and recommend a management algorithm. METHODS: Case series of 5 pediatric patients with a diagnosis of suppurative thyroiditis seen between January 1999 and April 2007. RESULTS: All 5 patients primarily presented with left-sided intrathyroidal abscesses. The number of infections from first presentation to the time of definitive diagnosis ranged from 1 to 5. Three patients underwent incision and drainage of the abscess once, and 2 had the procedure performed 3 times. Barium swallows identified a piriform sinus tract on the left side in 2 of the 5 patients. Telescopic hypopharyngoscopy identified the internal opening in all 5. Three were managed with complete excision of their tracts and 2 with cauterization of the internal opening with silver nitrate. All 5 are currently asymptomatic. CONCLUSIONS: Suppurative thyroiditis is a very rare infection in children. A left-sided intrathyroidal abscess should immediately arouse suspicion of a piriform sinus tract. Barium swallows may identify the etiology in some cases. Definitive diagnosis requires a hypopharyngoscopy, with detailed telescopic examination of the left piriform fossa apex. Endoscopic chemical cautery of the internal opening is a safe and effective technique, with very low morbidity, and has the potential for cure.

Suppurative thyroiditis with gas formation.

Acute suppurative thyroiditis with gas formation is very rare. A 70-year-old woman was admitted with dysphagia and fever. The clinical diagnosis of acute thyroiditis was supported by fine needle aspiration biopsy. X-ray examination showed gas collection within the soft tissue of the anterior neck and ultrasonography of the thyroid gland showed a cavity filled with thick liquid. The patient was treated with antibiotic therapy followed by thyroidectomy.

Microbiology and management of acute suppurative thyroiditis in children.

This review describes the microbiology, diagnosis and management of suppurative thyroiditis (ST). Staphylococcus aureus, Streptococcus pyogenes, Streptococcus epidermidis, and Streptococcus pneumoniae, are the predominant aerobic isolates. The most common anaerobic bacteria are Gram-negative bacilli and Peptostreptococcus spp. Agents that are rarely recovered include Klebsiella spp., Haemophilus influenzae, Streptococcus viridans, Salmonella spp., Enterobacteriaceae, Mycobacterium tuberculosis, atypical mycobacteria, Aspergillus spp., Coccidioides immitis, Candida spp., Treponema pallidum, and Echinococcus spp. Viruses have been associated with subacute thyroiditis, and include measles, mumps, influenza, enterovirus Epstein-barr, adenovirus, echovirus, and St Louis encephalitis. Therapy includes administration of antibiotics effective against the causative pathogen(s). Proper selection of therapy can be guided by culture of the lesion. Surgical drainage may be necessary in case of suppuration.

Clinical characteristics and management of acute suppurative thyroiditis in children.

BACKGROUND: Acute suppurative thyroiditis is an uncommon disease in children. This paper describes the clinical characteristics and management of children with acute suppurative thyroiditis treated during a 15-year period at National Taiwan University Hospital. PATIENTS AND METHODS: From 1985 to 2000, acute suppurative thyroiditis was diagnosed in 11 previously healthy children (6 boys, 5 girls) at the Department of Pediatrics. Their mean age at diagnosis was 6.4 +/- 4.4 years. Leukocyte count, acute-phase reactants, thyroid function, and thyroid autoantibodies were assessed. Samples were taken by thyroid needle aspiration for cytology study and pus culture. Underlying pyriform sinus fistula (PSF) was demonstrated by barium esophagogram. RESULTS: Leukocytosis was noted in six cases (55%) and acute-phase reactants were elevated in eight cases (73%). Neither thyroid autoantibodies nor thyroid dysfunction was detected in any of the patients. Barium esophagogram detected PSF in eight of 10 patients examined. Five (45%) patients had recurrent suppurative thyroiditis before surgery. Cytology and pus cultures were available for 10 patients. Polymorphonuclear cells were the main findings in the smear from thyroid aspirates. Twenty-two organisms were isolated from six patients (60%). Streptococcus species (45%) and anaerobic organisms (41%) were the most common pathogens isolated. Mixed infection was detected in five of six children who had a causative microorganism identified. The microorganisms were all sensitive to amoxicillin-clavulanate. CONCLUSION: PSF plays a role in the pathogenesis of acute suppurative thyroiditis in children. Streptococcus species are the most common pathogens in acute suppurative thyroiditis. Our results suggest that amoxicillin-clavulanate is the drug of choice for the treatment of this disease.
