Unusual adrenal metastasis and abdominal carcinomatosis secondary to Hurthle cell carcinoma of the thyroid.

Hurthle cell carcinoma (HCC) of the thyroid is an uncommon and relatively rare differentiated thyroid neoplasm. To our knowledge, no reported case of adrenal metastases with abdominal carcinomatosis secondary to HCC of the thyroid has been demonstrated by F-18 FDG PET/CT imaging. One report of adrenal uptake on I-131 whole-body scan with HCC exists. In this case report, we describe a patient with HCC who had a left adrenal metastasis with abdominal carcinomatosis that was discovered using F-18 FDG PET/CT imaging.
