Right Ventricular Mass: A Unique Approach to Tissue Diagnosis

A 57-year-old male with history of head and neck squamous cell carcinoma (HNSCC), in remission, presented with face and neck swelling and dyspnea. He was found to have recurrence of his HNSCC at the base of his tongue and a new right ventricular mass. Two endomyocardial biopsy attempts yielded benign tissue. A trans-jugular core needle biopsy performed, under fluoroscopy and intracardiac echocardiogram (ICE) guidance, revealed metastasis of primary tumor. To our knowledge, this is the first case reported in the literature of a core needle biopsy approach for diagnosis of a cardiac mass.
