Introduction: A hypercalcaemic crisis, also called para thyrotoxicosis, hyper parathyroid crisis or parathyroid storm, is a complication of primary hyperparathyroidism (PHPT) and an endocrinology emergency that can have dramatic or even fatal consequences if it is not recognised and treated in time.

Case Presentation: Two cases presented in the emergency department with critical hypercalcaemic symptoms and severe elevation of serum calcium and parathyroid hormone levels, consistent with a hypercalcaemic crisis. The first case, a 16-year-old female patient, had imaging data that highlighted a single right inferior parathyroid adenoma and a targeted surgical approach was used. Read More

Thyrotropin (TSH)-secreting pituitary tumors are the rarest functioning pituitary tumors. Nonetheless, they are not infrequently plurihormonal, as they may express/secrete hormones made by other pituitary cells derived from the Pit-1 lineage such as growth hormone (GH), prolactin (PRL), and α-subunit (αSU). However, adrenocorticotropin (ACTH) or gonadotropin secretion by such a tumor is exceptional. Read More

Background: Thyrotoxicosis and orbitopathy are the best-known expressions of Graves' disease. There are also rarer and less-known phenomena, such as thymic hyperplasia. Identification of these is important in order to avoid potentially unnecessary invasive interventions. Read More

Purpose Of The Report: Distinguishing between amiodarone-induced thyrotoxicosis (AIT) caused by excessive hormone synthesis (AIT-1) or by a destructive process (AIT-2) has important therapeutic implications, but is still difficult and debated. Tc-sestaMIBI thyroid scintigraphy (99m-STS) has been proposed as a tool for classifying the two forms.

Material And Methods: 30 AIT patients (11 females and 19 males) who underwent 99m-STS were retrospectively assessed for the present study. Read More

We report a case of a 27-year-old man with a history of untreated HIV who presented with fever, rash and leg cramps. Initial suspicion was high for an infectious process; however, after an exhaustive evaluation, thyrotoxicosis was revealed as the aetiology of his symptoms. Recent intravenous contrast administration complicated his workup to determine the exact cause of hyperthyroidism. Read More

Radioiodine (I) therapies on younger children with thyroid cancer and neuroblastoma can be challenging as they are required to be isolated for a period of time due to radiation safety concerns. At our hospital these therapies are performed in a purpose-built child-friendly therapy room. Nursing staff are able to provide personal care during the isolation period with minimum radiation exposure. Read More

Objectives: Transient hyperthyroidism has been documented following surgical manipulation or direct trauma to the normal thyroid gland. This has best been studied in patients following parathyroidectomy and also reported following trauma to the neck, strangulation, and vigorous palpation of the thyroid gland. It has not previously been reported following a thyroid ultrasound. Read More

Rationale: Thyrotropin-secreting adenoma (TSHoma) is rare. Even though the thyrotoxicosis is mild in patients with TSHoma, it is still a rare cause of arrhythmia, ignore of mild disfunction of thyroid function of TSHoma can lead to the delayed diagnosis of pituitary tumor or leading to recurring of complications. Graves' disease is an auto-immue endocrinological disorder. Read More

A 29-year-old man was referred to our department due to adrenal insufficiency with the inappropriate secretion of TSH (SITSH). Magnetic resonance imaging revealed a pituitary tumor. A weak TSH response in the TRH test, elevated sex hormone binding globulin (SHBG) levels, and the absence of a family medical history of SITSH or TRβ gene mutations supported the diagnosis of TSH-secreting pituitary adenoma (TSHoma).

Amiodarone is one of the most commonly prescribed antiarrhythmic agents in clinical practice owing to its efficacy, even with high toxicity profile. The high iodine content and the prolonged biological half-life of the drug can result in thyroid dysfunction in a high proportion of patients treated with amiodarone even after cessation of amiodarone. Both hypothyroidism and hyperthyroidism are common side effects that mandate regular monitoring of patients with thyroid function tests. Read More

Introduction: Anaplastic thyroid carcinoma (ATC) is one of the most aggressive human malignancies and constitutes approximately 1.6-5% of the malignant neoplasms of the thyroid gland. ATC usually manifests itself with the local symptoms due to a rapidly enlarging thyroid mass, and as other thyroid cancers, has only seldom been reported to cause thyrotoxicosis. Read More

In fibrous dysplasia/McCune-Albright syndrome (FD/MAS), bone and bone marrow are, to varying degrees, replaced by fibro-osseous tissue typically devoid of hematopoietic marrow. Despite the extensive marrow replacement in severely affected patients, bone marrow failure is not commonly associated with FD/MAS. We present a 14-year-old girl with FD/MAS, who developed pancytopenia and extramedullary hematopoiesis (EMH) with no identified cause, in the setting of iatrogenic thyrotoxicosis and hyperparathyroidism.

Curr Radiopharm 2017 Nov;10(3):146-154

Ion Chiricuta Institute of Oncology, Cluj-Napoca, Romania.

Background And Objective: The use of amiodarone for the treatment of ventricular and supraventricular dysrhythmias brings in organism an increased amount of iodine, interfering with thyroid function. If the treatment needs to be interrupted, iodine remains at abnormal levels for months or even years. The aim of the study was to review the literature regarding the optimal tests for early diagnostic and to analyze the role of nuclear medicine tests in the differential and correct assessment of the amiodarone-induced thyroid pathology.

Graves disease is the most common cause of thyrotoxicosis. Although medical intervention with antithyroid drugs (ATDs) is commonly the first choice of treatment in Korea, the remission rate associated with this approach is not satisfactory. During ATD therapy, low or undetectable serum levels of thyroid-stimulating hormone (TSH) receptor antibodies (TRAbs) have been reported to affect the incidence of Graves disease remission.

Background: In addition to its established role in oncologic imaging, F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) is useful for the assessment of inflammatory activity. However, subacute thyroiditis (SAT) in thyrotoxicosis is rarely detected during these scans.

Background: Thyrotoxic periodic paralysis (TPP) is an uncommon complication of Graves' disease, characterized by the triad of acute hypokalemia without total body potassium deficit, episodic muscle paralysis, and thyrotoxicosis. Graves' encephalopathy is an extremely rare form of encephalopathy associated with autoimmune thyroid disease (EAATD), characterized by neuropsychiatric symptoms, increased antithyroid antibodies and cerebrospinal fluid protein concentration, nonspecific electroencephalogram abnormalities, and cortico-responsiveness. Coexistence of both these complications in the same patient has not been reported before. Read More

Fever of unknown origin (FUO) is sometimes a diagnostic dilemma for clinicians.

Department of Nuclear Medicine, Tianjin First Central Hospital, Tianjin, China.

Objective: Amiodarone-induced thyrotoxicosis (AIT) is caused by amiodarone as a side effect of cardiovascular disease treatment. Based on the differences in their pathological and physiological mechanisms, many methods have been developed so far to differentiate AIT subtypes such as colour flow Doppler sonography (CFDS) and 24-h radioiodine uptake (RAIU). However, these methods suffer from inadequate accuracy in distinguishing different types of AITs and sometimes lead to misdiagnosis and delayed treatments. Read More
