Pericardial tamponade as initial presentation of papillary thyroid carcinoma

Cardiac tamponade as an initial presentation of papillary carcinoma with psammoma bodies and intranuclear grooves-A diagnostic dilemma

Involvement of body fluids by adenocarcinoma is a common phenomenon. However, metastasis to the pericardial fluid by adenocarcinoma is a rare occurrence. The most common malignancies associated with malignant pericardial effusion are carcinoma of the lung, breast, esophagus, melanoma, lymphoma, and leukemia. Here, we discuss a case of a 36-year-old female with hemorrhagic pericardial effusion presenting with cardiac tamponade and psammoma bodies which was suspected and reported as metastatic papillary carcinoma of thyroid on cytomorphology; however, the immunocytochemical and radiological features confirmed metastatic papillary adenocarcinoma of lung contrary to the thyroid which is more common and expected.

Sudden cardiac death due to primary malignant pericardial mesothelioma: Brief report and literature review

Sudden cardiac death is an unexpected clinical condition that typically occurs due to a cardiac cause, generally within 1 h of symptom onset, in people with known or unknown cardiac disease. Primary malignant pericardial mesothelioma, as a cause of sudden death, is an uncommon consequence of a rare disease. Herein, we present a case of cardiac tamponade due to a primary pericardial mesothelioma. Cytological, histopathology and gross post-mortem findings, in a previously asymptomatic 46-old-year man, are reported. The medical literature regarding this topic is also reviewed.

A Rare Case of Isolated Pericardial Effusion Detected by SPECT/CT on a Post-Therapeutic Radioiodine Whole-Body Scan

We reported a rare finding of isolated pericardial uptake detected by SPECT/CT on posttherapeutic radioiodine whole body scan. This case highlights the usefulness of hybrid SPECT/CT, with subsequent correlation with biochemical results, in ruling out metastatic pericardial effusion in the postsurgical radioiodine remnant ablation setting. The effusion was resolved after reinstituted thyroid replacement therapy. Recombinant thyrotropin is recommended to avoid such rare but life-threatening complication.

Neoplastic pericarditis as the initial manifestation of a papillary thyroid carcinoma

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.

Cardiac metastasis from thyroid carcinoma

Cardiac metastasis from epithelial thyroid cancer is a very rare and potentially serious complication. We have identified only 54 reported cases over a 130-year period. Here we review this literature. Cardiac metastases are frequently asymptomatic, but when symptoms develop these tend to be severe and often fatal. The prognosis of cardiac metastases from thyroid cancer is unclear as survival data are often missing or absent in reported cases. However, as many patients died suddenly from cardiac complications, the prognosis seems poor. Of those patients who survived, all underwent surgical intervention. Trans-thoracic echocardiography is the diagnostic modality of choice as it allows dynamic evaluation of intracardiac masses. Metastatic involvement of the heart from thyroid cancer is uncommon. Left untreated this complication seems likely to be fatal. Therefore, in patients with established thyroid malignancy who develop cardiac arrhythmias, new murmurs, or signs of cardiac decompensation, we suggest that cardiac metastases be considered. Echocardiography should be performed in patients with advanced thyroid cancer and cardiac symptoms or signs. If a cardiac metastasis is present, we recommend surgical intervention if possible.
