title: Coexistence of Primary Sarcomatoid Carcinoma of the Right Ventricle and Absence of Right Pulmonary Artery.
abstract: We describe the imaging features of a 48-year-old woman with primary sarcomatoid carcinoma originating from right ventricular outflow tract (RVOT) and isolated absence of right pulmonary artery (RPA). Computed tomography pulmonary angiography (CTPA) demonstrated the absence of RPA. Both transthoracic echocardiography (TTE) and CTPA revealed multiple masses filling and obstructing the RVOT. A palliative operation was performed on the patient, and the postoperative histopathology and immunohistochemical examination confirmed primary sarcomatoid carcinoma originating from the RVOT. The operation also confirmed the absence of RPA.
