title: Nonspecific iodine accumulation in surgical suture material mimicking follicular thyroid cancer bone metastasis in (131)I scintigraphy.
abstract: A 23-year-old man with follicular thyroid carcinoma and cervical lymph node metastases showed a clear I focus on the skull after radioiodine therapy; therefore, an osseous metastasis was suspected. I and MRI fusion suggested the I focus to be adjacent to an epicranial suture from an early childhood trepanation for epidural hematoma. Radio-guided surgery found dark brown material to be the source of the radiation and successfully removed the material. Subsequent electron microscopy revealed a thread within the dark brown material, suggesting suture material as the cause of I accumulation.
