Papillary thyroid carcinoma presenting as a giant cervical mass: a case report.

Papillary thyroid carcinoma (PTC) is a relatively uncommon malignancy. The prognosis is generally good and the mortality rate is low. PTC is more common in younger patients; incidence is two to three times higher in women and in individuals with radiation exposure to the neck. We report on a 75-year-old woman with PTC admitted to our clinic for a giant mass in the neck dating back ten years. A hyperintense huge cystic lesion and hypo-intense central solid component were seen on T1- and T2-weighted magnetic resonance imaging. No distant metastasis was present. The PTC was treated surgically and radioiodine (131I) treatment was applied postoperatively. No recurrence was observed one year later.
