Abstract:
Schwannomas are typically benign, indolent neoplasms. Primary pericardial schwannomas are extremely rare and arise from the cardiac plexus and vagus nerve innervating the heart. Few case reports have been documented to date. Pericardial schwannomas are difficult to diagnose at plain radiography or transthoracic echocardiography, often leading to further characterization with either CT or MRI. Biopsy is required for definitive diagnosis. A case of primary pericardial schwannoma of the posterior pericardium with concerns for compression of the left atrium and left ventricle is presented. © RSNA, 2021.
