Initial and Delayed Metabolic Activity of Palatine Tonsils Measured with the PET/CT-Dedicated Parameters.

One of the most critical elements in the palatine tonsils (PT) patients' management is to distinguish chronic tonsillitis and malignant tumor. The single-time-point (STP) 2-deoxy-2-[ F]fluoro-D-glucose positron emission tomography/computed tomography ( F-FDG PET/CT) examination offers the most significant sensitivity and specificity in the head and neck (H&N) region evaluation among commonly used methods of imaging. However, introducing dual-time-point (DTP) scanning might improve the specificity and sensitivity of the technique, limited by the F-FDG non-tumor-specific patterns, especially when comparing different metabolic parameters.

[Graves' disease and hyperprolactinemia in a patient with Noonan syndrome neurofibromatosis type 1].

We report the case of a 42-Year-old woman with Recklinghausen disease (neurofibromatosis type 1) and Noonan syndrome who developed Graves' disease. Hyperthyroidism, which had existed for two Years without treatment, led to the discovery of neurofibromatosis type 1. The diagnosis of Graves' disease was confirmed by blood hormone levels, thyroid gland ultrasound, radioisotope scan and thyroid iodine uptake.
