Papillary thyroid carcinoma can rarely present initially as neoplastic pericarditis and cardiac tamponade.
May warrant considering papillary thyroid carcinoma in unexplained pericarditis with tamponade; leaves open true incidence and mechanisms.
Neoplastic pericarditis represents approximately 5%-7% of the cases with acute pericarditis and is rarely the initial manifestation of malignancy. The most common cause is lung cancer, followed by breast cancer, lymphomas, leukemia, and esophageal cancer. Neoplastic pericardial disease is extremely rare in thyroid cancer, especially as the first manifestation. Here, we present a papillary thyroid carcinoma that was manifested with pericarditis and cardiac tamponade in a 49-year-old female.
