Key result
F-FDG PET/CT and contrast-enhanced CT successfully identified an intra-atrial metastasis (SUVmax 19.4) in a 54-year-old woman with sarcomatoid renal cell carcinoma.
Case Report (n=1)
Integration of F-FDG PET/CT and contrast-enhanced CT is useful for diagnosing and defining the anatomical relationships of cardiac metastases.
We describe the case of a 54-year-old woman, previously submitted to nephrectomy for sarcomatoid renal cell carcinoma and treated with antibiotics because of central venous catheter infection. An F-FDG PET/CT scan was obtained that demonstrated bone and lymph node metastases and also disclosed an irregular area of highly increased uptake (SUVmax 19.4) in the right atrium. Clinical data did not suggest a relapsed infection. A contrast-enhanced CT examination of the heart enabled the diagnosis of intra-atrial metastasis. Furthermore, integration between PET and cardiac 3-dimensional volume rendering proved useful for defining the anatomical relationships between atrial metastasis and large vessels.

Filippi et al. (2020) conducted a case report in Atrial metastasis from sarcomatoid renal cell carcinoma (n=1). F-FDG PET/CT and contrast-enhanced CT was evaluated. F-FDG PET/CT and contrast-enhanced CT successfully identified an intra-atrial metastasis (SUVmax 19.4) in a 54-year-old woman with sarcomatoid renal cell carcinoma.
