Predictive Factors of Radioactive Iodine Therapy Refractoriness in Patients with Differentiated Thyroid Carcinoma.

 Differentiated thyroid carcinoma (DTC) is the most prevalent endocrine malignancy, with radioactive iodine (RAI) therapy being a standard of care. However, RAI refractoriness, occurring in a subset of patients, significantly impacts survival rates. Understanding predictive factors for RAI refractoriness is crucial for optimizing patient management.

Radioiodine Therapy: Alternative for the Treatment of Complicated Thyroid Ectopia.

Thyroid ectopy is the presence of thyroid tissue outside its normal cervical location. Clinical manifestations of thyroid ectopy are varied. The latter complications can be life-threatening.

Radioiodine scan revealing a primary lung adenocarcinoma in a patient with differentiated thyroid carcinoma.

The radioiodine scan is a non-invasive imaging modality that allows for the visualization of functional thyroid tissue, as well as the detection of thyroid cancer remnants and metastases. However, it is important to note that radioiodine uptake is not exclusive to thyroid tissue and can lead to false-positive results if unexpected uptake occurs in non-thyroidal tissue. Herein, we present a case of a patient diagnosed with thyroid carcinoma, whose radioiodine scan demonstrated increased uptake in the thorax, corresponding to a lung carcinoma.

Unusual pathological fracture of the clavicle revealing primary hyperparathyroidism: a case report.

Background: Primary hyperparathyroidism revealed by a pathological fracture is very uncommon; in the majority of cases the discovery of lytic bone lesions on imaging examinations evokes in the clinician first a neoplastic etiology and a metabolic origin is often omitted. This case report adds to the existing literature as it describes an unusual presentation of primary hyperparathyroidism.

Case Presentation: We report a case of a 50-year-old Moroccan man, without any known tumor, who presented a fracture of his left clavicle with multiple osteolytic lesions on computed tomography suggesting bone metastases.

What role for radiobiphosphonates bone scintigraphy in the monitoring of an unusual bone giant cell tumor: a case report and literature review.

We report the case of 24 years old female patient, followed since ten years ago for bone giant cell tumor (GCT) of the right knee, which was complicated by pulmonary metastases. Surgical treatment and pulmonary metastasectomies have not allowed definitive cure of this disease with the appearance of metachronous bone lesions after eight years of evolution. The literature review confirms the originality of this observation: the age of the patient, the initial and metastasis locations and the occurrence of lung metastases with unfavorable prognosis.
