Intimal sarcoma of the pulmonary artery, a diagnostic enigma.

Heart malignancies are rare and difficult to diagnose at early stage. Usually they are discovered when they present disease symptoms. CT of the thorax with contrast, MRI of the thorax, endobronchial ultrasound (EBUS) or echocardiography (transthoracic and/or transesophageal) and fluorodeoxyglucose positron emission tomography-CT (FDG-PET-CT) can be used to diagnose this entity. We present a rare heart sarcoma and our diagnostic algorithm.
