A case of cardiac metastases from head and neck cancer presenting as hyperdense armored heart.

ABSTRACT

Cardiac metastases from head and neck cancers are sometimes found at autopsy, but are rarely found before death; therefore, case reports are uncommon. In this report, we describe a case of cardiac metastasis from head and neck cancer. Although asymptomatic at the time of detection, positron emission tomography-computed tomography was effective in ascertaining the diagnosis. However, patients with cardiac metastases usually have a poor prognosis, and unfortunately, the patient died shortly after detection. At autopsy, the patient had a "hyperdense armored heart" owing to a huge pericardial metastases. Here, we report the imaging and autopsy findings of a hyperdense armored heart owing to cardiac metastases from head and neck cancer.
