Thyroid tuberculosis mimicking multinodular goiter: a case report.

BACKGROUND: Mycobacterium tuberculosis is the second most common infectious cause of death in adults worldwide. The ability of this organism to efficiently establish latent infection has enabled it to spread to nearly one-third of individuals worldwide. Approximately 8 million new cases of active tuberculosis disease occur each year, leading to about 1.7 million deaths. The disease incidence is magnified by the concurrent epidemic of human immunodeficiency virus infection. A total of 1.3 million people died from tuberculosis in 2022. In 2022, an estimated 10.6 million people fell ill with tuberculosis worldwide, including 5.8 million men, 3.5 million women, and 1.3 million children. We report a case of thyroid tuberculosis presenting as multinodular goiter. Neck ultrasound was done and revealed abscess collection on the background of multinodular colloid goiter. The diagnosis of thyroid tuberculosis was confirmed by a positive GeneXpert of the pus sample and the presence of extensive caseous necrosis on cytopathology examination. Furthermore, anterior neck swelling may provide a diagnostic challenge by clinically mimicking multinodular goiter or thyroid neoplasms. Owing to its rarity and its tendency to pose a clinical diagnostic challenge, we decided to report it. CASE PRESENTATION: A 60-year-old retired female Ethiopian high-school teacher presented to University of Gondar Hospital, Gondar, Ethiopia with firm, nontender multinodular anterior neck swelling measuring at largest 2 × 3 cm that moves with swallowing. GeneXpert of the pus sample and cytopathology examination confirmed the diagnosis of thyroid tuberculosis, and the patient was started on 2 rifampicin-ethambutol-isoniazid-pyrazinamide/4 rifampicin-isoniazid 3 tablets by mouth/day, which is defined as the preferred first-line anti-tuberculosis regimen in Ethiopia, and pyridoxine 50 mg by mouth per day for 6 months. Since then, she has been followed with regular liver function tests. The patient has shown a smooth course with no significant adverse effects encountered. Currently, the patient has completed her anti-tuberculosis treatment and is doing well. CONCLUSION: In the clinical evaluation of a patient with anterior neck swelling, tuberculosis must be considered as a differential diagnosis in subjects from endemic areas for early diagnostic workup and management.

A rare case of primary tuberculosis in a solitary thyroid nodule.

Tuberculosis (TB) of the thyroid gland is extremely rare with fewer than 200 cases reported worldwide. We report a case of primary TB of the thyroid in a 73-year-old gentleman with no risk factors for TB, presenting with a painless right neck mass of one week's duration. A pre-operative ultrasound scan reported a solid-cystic, right TIRADS 5 nodule, and initial fine needle cytology showed granulomatous inflammation and was negative for AFB on Ziehl-Neelsen stain. A right hemithyroidectomy was done subsequently, and histology demonstrated necrotizing granulomatous inflammation, but TB-PCR detected Mycobacterium DNA. Primary TB of the thyroid is rare and can manifest in patients with no apparent risk factors for TB. Initial cytology may only yield granulomatous inflammation and surgery is needed to ascertain the exact cause of granulomatous inflammation and additional TB-PCR can help clinch the diagnosis.

Pancreatic tuberculosis: A systematic review of symptoms, diagnosis and treatment.

INTRODUCTION: Although pancreatic tuberculosis (TB) is traditionally considered to be a rare clinical entity, in recent times, an increase in the number of reports of pancreatic TB has been noted. We conducted a systematic review in order to summarise currently available data on pancreatic TB. METHODS: A comprehensive literature search of Medline, Scopus and ISI Web of Science databases was conducted in order to identify papers reporting cases of pancreatic TB. The eligibility criteria for inclusion in the review required that the studies reported patient(s) affected by pancreatic TB and that individual data on age, sex, clinical presentation and outcome were available. RESULTS: In total, 116 studies reporting data on 166 patients were included in the analysis. The majority of patients were males (62.1%) diagnosed at a mean age of 41.61 ± 13.95 years. Most cases were diagnosed in Asia (50.0%), followed by North America (22.9%), Europe (20.5%), Africa (4.2%) and South America (2.4%). Human immunodeficiency virus (HIV) infection was diagnosed in 25.3% of those affected. Pancreatic TB most frequently presented itself in the form of a pancreatic mass (79.5%) localised mainly in the head (59.0%) and less frequently in the body (18.2%) and tail (13.4%). Extrapancreatic TB involvement most frequently affected the peripancreatic lymph nodes (47.3%). More than half of patients (55.2%) were subjected to laparotomy, while 21.08% underwent endoscopic ultrasound fine-needle aspiration biopsy. The presence of TB was identified most frequently through histological analysis (59.6%), followed by culture (28.9%), staining (27.7%) and, in a smaller number, by polymerase chain reaction (9.6%) and cytology (6.6%). Almost all patients received anti-tubercular pharmacological therapy (98.2%), while 24.1% underwent surgery. Despite treatment, 8.7% of patients died. CONCLUSION: Increased awareness of pancreatic TB is needed, not only in endemic areas but especially in relation to HIV infection and other clinical conditions associated with immunoincompetence.

Primary Pituitary Tubercular Abscess: A Case Report.

Primary pituitary tubercular abscess is a very rare disease. It may present clinically with visual loss, headache, seizure, hormonal abnormalities or with cranial nerve palsies. MRI is the diagnostic modality and shows a cystic-solid mass in the sellar and suprasellar region, isointense on T1 and T2W images with heterogeneous areas and ring enhancement on contrast. Surgery remains the initial treatment and it is approached through the trans-sphenoidal/trans-nasal or transcranial route followed by anti-tubercular therapy. We report a case of primary pituitary tubercular abscess managed successfully with a brief review of its pathology. Keywords: abscess; pituitary gland; pyogenic; sella; tuberculosis.

Tuberculous Adrenal Abscess Presenting as Adrenal Insufficiency in a 4-Year-Old Boy.

We describe the case of a 4.8-year-old boy who presented with adrenal crisis. The advent of symptoms of adrenal insufficiency in the patient was at around 2 years of age. Congenital causes of adrenal insufficiency were considered over acquired etiologies owing to early onset of symptoms. However, on evaluation, he was found to have left adrenal abscess of tuberculous etiology. The aspirate culture grew multidrug-resistant Mycobacterium tuberculosis complex. He was initiated on glucocorticoid and mineralocorticoid replacement, along with second-line antitubercular therapy. Unique features of our case were early presentation, primary adrenal TB causing adrenal insufficiency, unilateral involvement with adrenal abscess localization, no identifiable extra-adrenal site of tubercular dissemination and resistance to first-line TB drugs.

Pituitary tuberculosis presented with pituitary coma.

BACKGROUND: Pituitary tuberculosis is very rare. Its diagnosis is difficult unless a bacteriological or histological evidence of tuberculosis. OBSERVATION: We report the case of a 54 years old woman who presented with a pituitary coma that occurred two weeks after the initiation of antituberculous therapy for cervical lymph node tuberculosis. Resonance magnetic imaging showed a pseudotumoral aspect of the pituitary gland. She had hormonal replacement and anti-tuberculous therapy. Outcome was favourable with the normalization of both the pituitary function and the pituitary volume. However, an acute hypopituitarism happened eight months after the withdrawal of antituberculous, which were taken during 12 months. The re initiation of anti tuberculous therapy and its extension to two years leaded to a prolonged remission. CONCLUSION: the three-phase outcome confirms the tuberculous origin of the hypophysitis in our patient.

[Bilateral adrenal tuberculosis: about a case]. / Tuberculose surrénalienne bilatérale: à propos d'un cas.

Isolated adrenal tuberculosis accounts for less than 2% of adrenal incidentalomas. This is the most frequent infectious cause of adrenal insufficiencies. We report the case of a 53-year old patient with no previous medical history presenting with adrenal insufficiency with slow progression over six months. Physical examination didn't show any mass or hepatosplenomegaly. Blood pressure was 120/60 mmHg. Laboratory tests didn't show inflammatory syndrome. LDH level was normal. CT scan showed bilateral hypertrophy of the adrenal glands characterized by calcifications. Intradermo tuberculin reaction was positive at 25mm. The analyses to detect Koch's bacillus in the sputum and in the urine were negative. Quantiferon® test was positive. Trial antibacillar treatment was started with clinical improvement and 5kg weight gain in 12 months. Hormonal assays were low.

Adrenal tuberculosis mimicking a malignancy by direct hepatic invasion: emphasis on adrenohepatic fusion as the potential route.

A 64-year-old female with primary adrenal insufficiency presented with a right adrenal mass showing quantitative nonadenoma features on dedicated adrenal computed tomography (CT). CT showed direct invasion of the mass to the adjacent hepatic parenchyma, and high uptake was noted on 18F-fluorodeoxyglucose positron emission tomography/CT. Laparoscopy revealed gross invasion of the adrenal lesion into the liver, which led to the en bloc resection including the involved liver. Polymerase chain reaction analysis of the surgical specimen revealed adrenal tuberculosis.

Primary tuberculosis of the thyroid gland: an unexpected cause of thyrotoxicosis.

We describe a 38-year-old Indian man who presented with a 2-week history of fever, night sweats and neck swelling who was found to be clinically thyrotoxic with a nodular goitre, tachycardia and high fever. Biochemical investigation revealed hyperthyroidism in association with deranged liver function tests and raised inflammatory markers. Ultrasound and CT scans of the neck revealed multinodular thyroid enlargement. He was considered most likely to have an acute infectious thyroiditis with a differential diagnosis of a toxic multinodular goitre and was started on carbimazole and antibiotics. He underwent fine needle aspiration of the thyroid which revealed necrotic cells and acid-fast bacilli, confirming a diagnosis of primary tuberculosis (TB) of the thyroid gland with no evidence of any other organ involvement on systemic imaging. He was started on TB therapy for 6 months and discharged with outpatient follow-up. Symptoms and biochemical markers subsequently resolved.

Tubercular thyroid abscess.

We encountered a patient who presented with neck swelling, difficulty in swallowing, voice change along with systemic features such as evening rise of temperature, chronic cough and weight loss. Ultrasonography of the thyroid gland revealed two cystic swellings. An ultrasound guided fine needle aspiration cytology was suggestive of tubercular abscess. The patient responded well to antigravity aspiration of the swellings and antitubercular treatment.

Extrapulmonary disseminated tuberculosis with tuberculous adrenalitis: a stitch in time saves nine.

A 40-year-old manual labourer presented with easy fatiguability, recurrent vomiting and loss of weight of 3 months, duration. Upon examination, there was significant axillary and cervical lymphadenopathy. No pallor, icterus or clubbing was evident. There was generalised hyperpigmentation and multiple oral ulcers. The blood pressure 90/60 mm Hg in the right upper limb in the supine position. Investigations showed a low serum cortisol. Mantoux test was strongly positive (20 mm).A fine needle aspiration biopsy of the cervical lymph node revealed reactive changes. Bone marrow aspiration and biopsy were normal. Cervical lymph node biopsy showed caseating granulomas suggestive of tuberculous lymphadenitis. A CT scan of the abdomen showed bilaterally enlarged adrenal glands with hypodense areas suggestive of necrosis. He was diagnosed with extrapulmonary disseminated tuberculosis with tuberculous adrenalitis. He was started on directly observed therapy (DOTS) for disseminated tuberculosis and 40 mg of prednisolone. He is improving with treatment.

Addison's disease presenting with muscle spasm.

Primary hypoadrenalism has various causes and protean manifestation. We report a young female patient who presented with severe muscle spasm as her primary complaint. On evaluation she was found to be a case of Addison's disease secondary to adrenal tuberculosis. Her muscle spasm disappeared rapidly with replacement dose of glucocorticoid.
