thyroid scintigraphy has been helpful in detecting and evaluation of thyroid nodules. sodium pertechnetate tc-99m is the most commonly used radionuclide for thyroid imaging because of its general availability, favorable dosimetric characteristics and low cost. but, there are reports of occasional disparity in isotope uptake in lesions compared with radioiodide. in order to determine percentage ...

UNLABELLED BACKGROUND Thyroid hemiagenesis is a rare anomaly, more commonly seen on the left side (ratio 4:1) and in females (ratio 3:1). The first to describe this anomaly was Handfield Jones in 1852. CASE PRESENTATION We present a 66 year old female patient with right thyroid hemiagenesis, parathyroid adenoma on the side of hemiagenesis and parathyroid hyperplasia on the contralateral si...

Introduction. Although follicular thyroid carcinoma is a rare malignant tumor, up to 20% of the patients are threatened by potential complications resulting from infiltrating tumor growth into surrounding tissues. Case report. A 66year-old female came to hospital with the presence of a growing thyroid nodule of the left lobe. Ultrasonic examination showed a 8 cm hypoechoic nodule in the left lo...

CLINICAL SUMMARY Mediastinal enlargement and a solitary pulmonary nodule were detected on a 68-year-old male patient’s chest radiograph during routine annual examination. Computed tomography and magnetic resonance imaging revealed a lobulated, solid, and well-demarcated right paratracheal mass 6 3 4 3 4 cm in dimension (Figure 1). The solitary, heterogeneous parenchymal mass located in the righ...

Objective: The current study aimed to determine the efficacy of radioiodine-131 (131I) ablation therapy with thyroid hormone replacement one day before 131I administration in patients with well-differentiated thyroid cancer (DTC). Methods: This retrospective study included 29 patients who underwent 131I therapies twice for DTC during 6-12 months.  Since all the patients obviously had residual l...

A case of follicular thyroid cancer with intense focal Methionine uptake on 11C-Methionine PET/CT is reported here. The use of 11C-Methionine PET in differentiated thyroid cancer is currently being investigated as a surrogate tracer compared to the more widely used 18F-FDG PET. This case illustrates the potential incremental value of this modality, not only in the localizing of parathyroid aden...
