18F-Fluorocholine, 18F-FDG, and 18F-Fluoroethyl Tyrosine PET/CT in Parathyroid Cancer.

We report on a 71-year-old woman presenting with biochemical features indicating recurrent disease in long-term follow-up of left-sided parathyroid carcinoma. She had undergone several surgical procedures including total thyroidectomy, partial resection of the esophageal wall, and curative neck radiation 12 years previously. PET/CT using F-fluorocholine revealed high uptake in local relapse in the lower neck, comparable to F-FDG, whereas only faint uptake was observed with F-fluoroethyl tyrosine.

Thyroid screening in HIV-infected patients with antiretroviral therapy.

Background: The literature reports an increased incidence of thyroid disorders in human immunodeficiency virus (HIV)-positive persons. We therefore retrospectively analyzed the strategy of collecting thyroid parameters on a routine basis.

Methods: Overall 410 patients (147 women, 263 men; age, 10-74 years; median age, 45 years) were included.

Malignant disease as an incidental finding at ¹⁸F-FDG-PET/CT scanning in patients with granulomatous lung disease.

Purpose: Fluorine-18 fluorodeoxyglucose (¹⁸F-FDG)-PET/computed tomography (CT) is used for assessment of the extent and activity of disease in patients with inflammatory granulomatous lung disease, in particular sarcoidosis and tuberculosis. The aim of this retrospective analysis was to assess the value of ¹⁸F-FDG-PET/CT in the identification of previously unknown malignant disease during routine investigation of granulomatous lung disease.

Materials And Methods: From July 2008 to December 2013, a total of 122 patients with tuberculosis (76 male and 46 female patients; age range 19.

Expression of somatostatin receptor subtype 2 and subtype 5 in thyroid malignancies.

Aim: To retrospectively analyse the expression of somatostatin receptor subtypes 2 (SSTR 2) and 5 (SSTR 5) in thyroid malignancies, possibly the most relevant subtypes for targeted therapy with somatostatin peptide radioligands. In addition, findings were also correlated with the course of disease.

Patients, Methods: 87 consecutive patients (59 women, 28 men) with thyroid malignancy were included; 52 had papillary carcinoma, 24 follicular carcinoma, six medullary carcinoma, two poorly differentiated carcinoma and three anaplastic carcinoma.

[Clinical application of biopsy of the sentinel lymph node in breast carcinoma].

Sentinel lymph node (SN) biopsy in primary breast cancer seems to be an alternative to complete axillary lymph node dissection for evaluation of the axillary lymph node status in selected patients. Following evaluation of the technique of SN biopsy, we applied SN biopsy clinically to 23 selected patients. A lymphoscintigraphy was performed preoperatively to evaluate lymphatic drainage.

[Hyperthyroidism caused by TSH producing hypophyseal adenoma].

Thyrotropin (TSH-)producing adenomas of the anterior pituitary gland are the least frequently encountered ones and constitute a very rare cause of hyperthyroidism. The case is presented of a 58 year old male patient with a well-known history of hyperthyroidism over a period of at least 9 years growing goiter. Despite different forms of medical treatment he presented a constant clinical pattern consisting of restlessness and paroxysmal tachycardial atrial fibrillation.
