Métastase rénale d’un carcinome vésiculaire de la thyroïde révélée par le balayage du corps entier à l’iode 131

Abstract

Distant metastasis of differentiated thyroid carcinoma generally affect lung and/or bone tissue. Renal metastasis from thyroid carcinoma is extremely rare. We report a case of renal metastasis from a follicular thyroid carcinoma in a 55-year-old man, occuring 11 years after total thyroidectomy, fortuitously discovered on a whole body scan carried out after 131-iodine therapy for neck recurrence of disease. Salient features of our clinical case are the fortuitous mode of discovery the unilateral localization of metastases and especially the long time interval which separates its detection from that of the primitive tumour. This case report exemplifies the useful role of the whole body scan carried out after 131-iodine therapy better adapted to reveal often undetectable occult metastases with low dose, but also to ensure a regular and protracted follow-up of patients treated for differentiated thyroid carcinoma.
