The role of 18F-FDG PET/CT testing in the management of a papillary thyroid carcinoma

چکیده
Introduction Thyroid papillary carcinoma represents 75% of all thyroid cancer cases. It is more prevalent in the young and middle age group of patients. Distant metastases occur in 10% of cases. Metastases to lymph nodes can be the first sign of microcarcinoma. This is a case report where thrombophlebitis of popliteal vein and pulmonary embolic disease appeared to be the first manifestation of the carcinoma. The chest CT scan showed mediastinal lymfoadenopathy representing metastases of papillary thyroid cancer. The 18 F-FDG PET/CT scans had a major diagnostic and prognostic value in the overall management.

Introduction: Papillary thyroid carcinoma (PTC) constitutes 75–85% of all thyroid cancers. PTC usually presents as a subtle, commonly slow-growing, painless thyroid mass or a solitary nodule in the neck. This presentation of a cystic neck lump, without the presence of a thyroid nodule, may imitate the course of a benign disease, thus delaying diagnosis and proper treatment. Case Report: Thr...

Objective(s): In clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (DTC) patients with high serum thyroglobulin (Tg) and negative 131I whole-body scan (WBS) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. The purpose of this study was to evaluate the value of 18F-FDG PET/CT scan in DTC patients with high seru...

F-18 FDG is the most widely used tracer in molecular imaging and it is applied for many purposes mainly in malignant diseases. Incidental finding are common in FDG-PET/CT imaging and includes benign and malignant lesions. Among the rare tumors , adrenal oncocytomas are uncommon findings and incidental findings of thyroid malignancies are not rare. Oncocytoma is a rare adrenocortical tumor and m...
