BACKGROUND: Papillary thyroid carcinoma is a common neoplasm arising from follicular cells of the thyroid. Differentiating the neck mass between thyroid paraganglioma and papillary thyroid carcinoma is often difficult.
CASE REPORT: We report a 16-year-old girl with painless neck mass. Physiological goiter was suspected initially but we found papillary thyroid carcinoma.
RESULTS: CT neck revealed hyper vascular lesions in bilateral lobes of thyroid. DSA imaging was done for further evaluation which showed high flow fistulous type of lesion supplying from superior thyroidal artery raising suspicion of paraganglioma. Postoperative biopsy ultimately revealed papillary carcinoma of thyroid in the background of hashimotos' thyroiditis with metastatic deposits in neck lymph nodes.
CONCLUSION: Thyroid paraganglioma is a rare type of tumor, it arises from inferior laryngeal paraganglioma within thyroid capsule and is as thus difficult to distinguish from thyroid carcinomas. A biopsy is the best diagnostic choice but immunohistochemistry is the only investigation which is considered as the gold standard for distinguishing between these two diseases.
