Toxic autonomous thyroid nodule following neck irradiation.
A 37-year-old male with a history of neck irradiation in childhood presented with thyrotoxicosis due to an autonomous thyroid nodule. Adjacent to the nodule was a radiation scar from radiotherapy administered 35 years previously. Hemithyroidectomy was performed and histological examination excluded malignant change. Long term follow-up should continue to detect possible nodule formation in the contralateral lobe.
