[False positive vascular increased uptake during cervico-thoracic radioiodine scan]

The total body radioiodine 131 scan is an important tool for the postoperative management of thyroid carcinomas. However, it has multiple false positives. Congenital or acquired vascular abnormalities such as ectasis or aneurism can be responsible for an increased uptake during the whole body radioiodine I[131] scan because of stagnation of the iodine and because of its delayed elimination when these malformations are present. We report the case of such a false positive

Thyroid primitive lymphoma on Hashimoto thyroiditis: about a case

Lymphoma is a rare form of malignant thyroid tumor. It often develops on concomitant or pre-existing thyroid disease. We present a case of thyroid lymphoma that developed on a Hashimoto thyroiditis and we review the clinical characteristics of the evolution of this disease as well as the controversy surrounding its management. Our patient was a 44 year old female that had surgery in our department because of a rapidly growing thyroid nodule associated with symptoms of cervical compression. Total thyroidectomy was performed. The pathology report concluded that it was a B cell lymphoma associated with Hashimoto thyroiditis. The treatment was completed by chemotherapy but the local evolution could not be stopped
