A Case of Miliary Tuberculosis Complicated by Thyroid Involvement: Managing Rifampicin-Induced Thrombocytopenia With Rifabutin.

This case report presents an unusual occurrence of miliary tuberculosis with thyroid tuberculosis in a 75-year-old male patient, who successfully completed the treatment with rifabutin after rifampicin-induced thrombocytopenia. The patient has been suffering from diabetes mellitus and chronic heart failure, and had coronavirus disease of 2019 (COVID-19) just before being diagnosed with miliary tuberculosis. The patient had not been prescribed immunosuppressants and steroids. Chest computed tomography (CT) scans revealed multiple tiny nodules diffusely and equally distributed in bilateral lung fields. Subsequently, polymerase chain reaction (PCR) techniques on the urine samples and culture of sputum demonstrated positivity for Mycobacterium tuberculosis. Thus, we conclusively identified miliary tuberculosis and initiated treatment using anti-tuberculosis drugs. During treatment, the patient developed thyroid tuberculosis, resulting in an enlarged thyroid and hoarseness, but these symptoms improved with continued use of the anti-tuberculosis drugs. Moreover, regarding treatment, the rifabutin dosage was completed after changing drugs due to rifampicin-induced thrombocytopenia. Notably, miliary tuberculosis is rarely complicated by thyroid tuberculosis as a paradoxical reaction, and the substitution of rifabutin for rifampicin-induced thrombocytopenia is not fully studied. We present this case alongside relevant prior data for comprehensive clinical insight.

Thyroid tuberculosis and cold abscess after infection with COVID-19: A case report.

There is mounting evidence that coronavirus disease 2019 (COVID-19) can cause immune dysregulation. The consequence of this immune dysregulation may contribute to susceptibility to tuberculosis (TB). Thyroid gland involvement by TB is extremely uncommon and typically the result of disseminated infection. It can be hard to diagnose because there are no identifiable symptoms. We present the case of a Chinese patient who had a fever again after COVID-19 infection that was finally diagnosed as thyroid tuberculosis with a cold abscess. Clinicians should maintain a high index of suspicion for high-risk patients from endemic regions with medical comorbidities, such as immunocompromised disease and malnutrition.

Thyroid tuberculosis associated with papillary microcarcinoma: case report and review of literature.

Introduction: Thyroid tuberculosis (TB) is extremely rare. Infection may first occur in the thyroid gland or may be secondary to TB in other parts of the body. The diagnosis is rarely made clinically because the disease's variable presentation often resembles that of a malignancy or an euthyroid nodular goiter. Case report: We present the case of a 40-year-old woman, who presented multiple thyroid nodules in both lobes. Two of these nodules were classified as EU-TIRADS V (European Thyroid Imaging and Reporting Data System). The ultrasound also found an adenopathy of the inferior part of the jugular lymphatic chain, in favor of malignancy. The histopathological examination after total thyroidectomy showed thyroid TB, associated to a papillary microcarcinoma of the right thyroid lobe, and the final examination of the adenopathy showed similar granulomas with caseous necrosis, and no signs of metastasis. Clinical discussion: Thyroid TB is very rare. Its diagnosis is difficult due to a lack of specific signs and symptoms, which is why the diagnosis is most commonly made on pathological examination after thyroid surgery. It is well known that mycobacterial infection creates an environment of chronic and persistent inflammation, with possible DNA damage. This can create a microenvironment that is highly conductive to carcinogenesis, which could explain the discovery of papillary microcarcinoma in addition to thyroid TB in our patient. Conclusion: This report presents a rare case of malicious growth development of thyroid nodules and thyroid TB. Therefore, physicians must always be vigilant when managing thyroid nodules, as there is always the possibility of malignant lesions associated to an inflammatory or infectious cause.

Diagnostic and Management Guidelines of Thyroid Tuberculosis: Our Experience and Systematic Review.

Objective: Thyroid tuberculosis has non-specific clinical presentation, difficult diagnosis and specific medical management. The aim of this article is to present and share a review of the English-language literature on thyroid tuberculosis in order to gain a better understanding of diagnostic methods and provide guidelines for its management and to present our experience of three cases. Methods: The systematic search of the literature was performed on Pubmed and Medline from 1950 to 2019 according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement. Results: We retrieved 13 manuscripts meeting our criteria from the search. There were 7 case series, and 6 manuscripts with review of the literature. Conclusion: Direct histopathological demonstration is the best diagnostic modality. FNAC is the study of choice and PCR assay increases its sensitivity. The standard short course ATT for 6 months is recommended for isolated thyroid TB and for widespread disease, 12 months therapy is recommended. Surgery is reserved for failure of medical therapy and abscess formation.

Primary thyroid tuberculosis mimicking papillary carcinoma of thyroid: a rare case report.

Primary thyroid tuberculosis is an extremely rare extrapulmonary involvement by the causative agent, Mycobacterium tuberculosis. Its rarity and resemblance to thyroid malignancy led to unnecessary aggressive operative interventions. Case Presentation: A 54-year-old female presented with recent onset dysphagia and foreign body sensation in the throat for 3 months, and anterior neck swelling since last 10 years. Clinical Findings and Investigations: A single nodular firm anterior neck swelling was present which moves with deglutition. Thyroid function test was normal. Ultrasonography thyroid revealed TIRADS-3. Fine-needle aspiration cytology was suggestive of papillary carcinoma of thyroid. Interventions and Outcome: Total thyroidectomy with central compartment neck dissection was performed. Histopathology of the thyroid specimen revealed tubercular thyroiditis. Postoperatively, Mantoux test and interferon gamma radioassay were positive. Antitubercular therapy was given for total of 6 months. Conclusions: With ultrasonography-guided fine-needle aspiration cytology, preoperative diagnosis of primary thyroid tuberculosis is quite challenging even in tuberculosis endemic countries. So, it should be considered one of the differential diagnoses despite negative relevant history and without clinical cervical lymph nodes involvement with cytology proven suspicious papillary thyroid cancer before proceeding for surgical intervention.

Clinical diagnosis and treatment of primary thyroid tuberculosis: a retrospective study

ABSTRACT BACKGROUND: Primary thyroid tuberculosis (PTT) is an uncommon type of extrapulmonary tuberculosis, which is caused by Mycobacterium tuberculosis. It does not have specific clinical manifestations, and most cases are diagnosed through postoperative histopathological examination. OBJECTIVE: To evaluate the diagnostic pattern and management strategy among patients with primary thyroid tuberculosis. DESIGN AND SETTING: Retrospective study on patients with primary thyroid tuberculosis in the First Hospital of Jilin University (Changchun, China). METHODS: Between March 2015 and June 2020, nine cases of PTT were diagnosed and treated in the Department of Thyroid Surgery of the First Hospital of Jilin University. Age at diagnosis, primary symptoms, preoperative biopsy, operation method, pathological classification, acid-fast staining test, anti-TB therapy and prognosis were registered in order to explore the appropriate protocol for diagnosis and treatment of this disease. RESULTS: None of the patients was diagnosed with thyroid tuberculosis before surgery. All the patients underwent surgery. Granulomatous changes or caseous necrosis in thyroid tissue were found through postoperative histopathological evaluation. Polymerase chain reaction (PCR) results for Mycobacterium tuberculosis were positive in all patients. Most patients had a good prognosis after surgery and anti-tuberculosis drug therapy. CONCLUSION: PTT is a rare disease. It is important to improve the preoperative diagnosis. Preoperative diagnostic accuracy relies on increased awareness of the disease and appropriate use of preoperative diagnostic methods, such as PCR detection, fine-needle aspiration cytology, acid-fast bacillus culture, ultrasound and blood sedimentation. PCR detection of M. tuberculosis is recommended as the gold standard for diagnosis.

Cold abscess as a primary manifestation of thyroid tuberculosis.

Tuberculosis remains the highest cause of infection-related mortality in low- and middle-income countries. Extra-pulmonary tuberculosis is often misdiagnosed because of the nonspecific clinical presentations and gaps in the laboratory assessment. Delayed and misdiagnosis can cause increased risks of morbidity and potential community transmission. Primary thyroid tuberculosis is very rare presentation even in the endemic area. We presented a Case Illustrated of a patient with cold abscess as a primary presentation of thyroid tuberculosis. Difficulty in the diagnosis and treatment were described. Although very rare, atypical presentation of extra-pulmonary tuberculosis in the thyroid gland requires thorough anamnesis and in-depth examination. Clinicians should put high-index suspicion on high-risk patients from endemic areas with medical comorbidity including immunocompromised disease and poor nutritional status. Our report underlines the importance of thorough medical assessment for unusual presentation of thyroid tuberculosis.

Thyroid tuberculosis diagnosed as papillary thyroid carcinoma with fever of unknown origin.

Thyroid tuberculosis is a rare disease, very few cases have been reported. It is difficult to diagnose because of no typical characteristics. We report on a patient who underwent surgery for suspected thyroid carcinoma, but who was then diagnosed with thyroid tuberculosis. The patient was a woman in her 70s. She had been diagnosed with chronic renal failure and had been on peritoneal dialysis. She complained of fever and a painful left anterior neck swelling. Computed tomography showed thyroid tumor with cervical lymph node swelling, ultrasound-guided fine needle aspiration cytology was suspected for papillary thyroid carcinoma. We performed surgery to confirm the diagnosis and determine treatment. Procedures for thyroid carcinoma were followed, including left lobectomy of the thyroid gland, central lymph node dissection and right cervical lymph node resection. Pathological examination found no malignant findings in the thyroid tissue but did find a granulation layer even in the right cervical lymph node. Tuberculosis-specific IFN-γ assay was positive, we diagnosed thyroid and cervical lymph node tuberculosis. Postoperatively, the neck pain and fever improved, she was treated as an outpatient with antituberculosis drugs therapy. Thyroid tuberculosis must be considered in patients with immunocompromised, such as this patient, who was on peritoneal dialysis.

'Primary Thyroid Tuberculosis'-The Masquerader: A Case Report.

Tuberculosis of thyroid is a rare entity even among highly prevalent regions of tuberculosis. Primary tuberculosis of thyroid is even more rarer. The reason is attributed to the inherent relative immunity of the thyroid gland. Clinical manifestation is unpredictable accounting to both asymptomatic and variable benign and malignant mimicking symptoms. Clinical course may too vary depending on the thyroid dysfunction and complications. Aspiration cytology is diagnostic, though the yield is low. Histological diagnosis, depicting caseating granuloma added with acid fast staining confirms the diagnosis. High clinical suspicion is to be maintained to prevent total thyroidectomy.

Acute Suppurative Thyroiditis Secondary to Tuberculosis with Superimposed Bacterial Infection: A Case Report.

Acute suppurative thyroiditis is a rare and potentially fatal condition. We present a case of an 18-year-old Malay female who presented with one-week history of painful right sided neck swelling, fever and odynophagia. Neck CT confirms ruptured multiloculated abscess with posterosuperior extension into prevertebral space. Pus and tissue cultured Streptococcus anginosus and Eikenella corrodens with positive TB PCR. She responded well to ampicillin/sulbactam and anti-tuberculosis treatment with no evidence of residual collection from ultrasound.

Primary thyroid tuberculosis: a case report.

Involvement of the thyroid gland by tuberculosis is very rare and is usually secondary to disseminated infection. Very few cases of primary thyroid tuberculosis have been described even in countries with a high incidence of this disease. We present the case of a Spanish patient operated for a suspicious thyroid nodule that was finally diagnosed as primary thyroid tuberculosis.

La afectación de la glándula tiroidea por tuberculosis es muy rara y generalmente es secundaria a una enfermedad ­diseminada. Se han descrito muy pocos casos de tuberculosis tiroidea primaria incluso en paises con alta incidencia de esta enfermedad. Presentamos el caso de una paciente española operada por un nódulo tiroideo sospechoso que fue finalmente diagnosticado como tuberculosis tiroidea primaria.

Thyroid tuberculosis.

Thyroid tuberculosis is a rare disease. Its incidence is low even in countries where prevalence of pulmonary tuberculosis is high (0.1-0.4%). In literature, there are only a few cases which were diagnosed as thyroid tuberculosis. It can be explained by a high resistance of the thyroid gland to infectious processes. However, the prevalence of tuberculosis has increased worldwide and thyroid involvement can be a primary manifestation of the disease. The incidence of extrapulmonary tuberculosis has been showing a progressive increase in the recent years(Barnes and Weatherstone, 1979). The most frequent clinical presentation is a solitary thyroid nodule that may present as a cystic nodule. It may also present as thyroid abscess with pain, fever and other non-specific signs and symptoms. ATT results in complete cure therefore it is important to differentiate it from other form of thyroiditis. Patients are usually euthyroid, but cases of hypothyroidism and hyperthyroidism are described. For accurate diagnosis of thyroid tuberculosis, clinical and radiological features are nonspecific and histological examination is required for confirmation of diagnosis. PCR may help in diagnosis. The authors encounter 3 cases of thyroid tuberculosis in last 5 year which are described in this article. The aim of this study is to review all the cases published in literature to describe clinical presentation, appropriate diagnostic method and possible treatment options of the disease.

Extensive Multisystemic Disseminated Tuberculosis in an Immunocompetent Patient.

Extrapulmonary tuberculosis is uncommon and has an insidious onset with slow evolution and a paucibacillary nature. Here, we present a case of disseminated tuberculosis in an adult immunocompetent man presenting with morphologically different types of cutaneous lesions (i.e., multiple subcutaneous abcesses and multiple noduloulcerative lesions with discharging sinuses with seropurulent fluid). Extensive screening in the form of routine blood investigations, serologies, skin biopsy, Montoux test, sputum examination, chest and skull roentgenogram, noncontrast computed tomography chest and abdomen, contrast-enhanced computed tomography of the skull, and magnetic resonance imaging of lumbosacral spine with screening of the whole spine revealed extensive involvement of the skin, subcutaneous tissue, lungs, lymph nodes, skull bone, mandible, ribs, scapula, pelvis and Pott's spine, and thyroid.

Tuberculosis of the Thyroid-a Diagnostic Enigma.

Thyroid tuberculosis is very uncommon even in countries where tuberculosis is endemic. It is commonly seen secondary to tubercular infection of other organ or tissue by hematogenous spread. There are many different presentations of thyroid tuberculosis. Before the advent of fine needle aspiration cytology (FNAC), all patients had surgery and thyroid tuberculosis was diagnosed only on biopsy of specimen. Nowadays, FNAC can confirm the diagnosis in many cases, and the patient can be cured by standard anti-tubercular treatment without the need for surgery. Surgery is required only when there is suspicion of malignancy and FNAC is inconclusive.

Cytological Diagnosis of Primary Thyroid Tuberculosis.

Primary thyroid tuberculosis is an extremely rare disease, even in countries where other forms of tuberculosis are abundant. TT has no age bar but usually affects women in fourth and fifth decade. Hereby, we report a case of 16-years-old girl presented with complaint of progressively increasing, painful thyroid swelling. Diagnosis of TT was made on cytology and there was no evidence of involvement of any other organ by tuberculosis. Despite of its rarity, TT is usually misdiagnosed. So, a clinician should always consider this entity in the differential diagnosis of thyroid swelling. Fine needle aspiration cytology is the best diagnostic method and can result in the avoidance of unnecessary thyroid surgeries.

Role of ultrasound evaluation for the diagnosis and monitoring of thyroid tuberculosis: A case report and review of the literature.

Thyroid tuberculosis (TT) is an extremely rare condition, with acute abscess formation being the most uncommon form of presentation. Mycobacterium tuberculosis may affect the thyroid gland through hematogenous spread from an extra-thyroid focus of disease or by direct extension from adjacent cervical lymph nodes. Due to the non-specific imaging findings and the variable clinical manifestations, TT is rarely diagnosed promptly prior to percutaneous biopsy or surgery. The present study reports the dynamic monitoring of the sonographic features of a case with thyroid tuberculosis that was diagnosed by a thyroid ultrasound (US) scan, confirmed by a US-guided core-needle biopsy and followed-up sonographically during the whole course of treatment.

Papillary thyroid cancer coexisting with thyroid tuberculosis: A case report.

The current study presents the case of a 56-year-old female, with thyroid nodules showing signs of malignancy under B-mode ultrasonography, who was admitted to Shaoxing People's Hospital. A histopathological examination revealed the coexistence of papillary thyroid cancer (PTC) and thyroid tuberculosis (TB). A total thyroidectomy and selective neck dissection (left side, levels III, IV and VI) were performed. This report presents a rare case showing the malignant growth of thyroid nodules and the development of thyroid TB, which implicates the possible role of mycobacterial infection in the tumorigenesis of PTC.

Tuberculous abscess of the thyroid / Journal of the ASEAN Federation of Endocrine Societies

Tuberculosis (TB) of the thyroid gland is rare, with acute abscess formation being the least common form of presentation. As such, TB of the thyroid may be overlooked as an initial clinical impression. A careful approach by history, physical examination, laboratory testing and radiologic imaging may aid in defining the etiology of the thyroid abscess, but these remain nonspecific. An accurate diagnosis may only be made by histologic examination. We present a case of a tuberculous abscess of the thyroid gland in a 37-year-old female. TB of the thyroid should also be considered when evaluating patients presenting with a painful thyroid nodule.

Tuberculous orbital abscess associated with thyroid tuberculosis.

PURPOSE: To report an unusual presentation of tuberculosis. CASE REPORT: A six-year old boy presented with left upper lid swelling of 15 days' duration and an asymptomatic midline neck mass from 2 months ago. Imaging studies, and microbiologic tests which demonstrated acid-fast bacilli in the fine needle aspirate of the thyroid mass, both confirmed a diagnosis of cold tuberculous thyroid abscess with presumed hematogenous spread to the orbit. The patient demonstrated marked improvement of both lesions with antitubercular drugs. CONCLUSION: This case illustrates a very rare association of orbital and thyroid tuberculosis.
