Abstract:
We report a thyroid-shaped iodine uptake in the scrotum incidentally detected on an 131I whole-body scan (WBS). A 62-year-old man with papillary thyroid carcinoma underwent 131I ablation therapy after total thyroidectomy. A postablation whole-body scan after 7 days revealed a butterfly-shaped uptake in the lower pelvic region on the anterior image, which was suspected to be an unusual form of urinary contamination. However, additional lateral images demonstrated that the tracer activity was not superficial. Computed tomography revealed a bilateral scrotal hydrocele that corresponded to the 131I uptake in the lower pelvis on WBS. This case presents a previously unreported hydrocele incidentally detected on 131I WBS, with iodine uptake in the bilateral scrotal regions, shaped like a thyroid gland.
