Background: Cardiac metastasis of cervical cancer is rare and has a poor prognosis. Some reports suggest that Positron Emission Tomography (PET) is useful in the diagnosis of cardiac metastasis. Case: A-40-year-old woman who had a history of cardiac surgery was treated with concurrent chemo-radiotherapy for stage IIIA cervical cancer (squamous cell carcinoma) and showed good response to treatment one year earlier. At 9 months post-treatment, Computed Tomography (CT) scan showed a thrombus in the left atrium, and the patient was started on warfarin. Three months later, a CT scan showed a mass in the right ventricle. PET scan showed no significant accumulation, and open heart surgery was performed with a preoperative diagnosis of thrombus. However, the postoperative pathological diagnosis was cardiac metastasis. Four months after the heart surgery, the tumor recurred in the right ventri.. View More»
