Abstract

A 31-year-old man received radioiodine (I-131) treatment after bilateral total thyroidectomy and central lymph node dissection. After the treatment, I-131 whole-body scintigraphy showed focal activity in the right testicular region. SPECT/CT images showed focal activity localised in the right epididymis, and US images showed a hypoechoic lesion consistent with spermatocele.
