Cardiac involvement from renal cell carcinoma is rare but well-recognized
entity with several cases reported in literature. In majority of cases, the
tumor reaches the right heart cavities through a neoplastic thrombus within
inferior vena cava.  Other mechanisms are
dissemination via hematogeous spread and direct extension from either
mediastinal or lung lesions involving pulmonary veins. Left heart involvement
from renal cell carcinoma with normal inferior vena cava is extremely rare.
Direct extension of metastatic pulmonary mass to left atrium from renal cell
carcinoma via pulmonary veins is even rarer.

We report a case of left atrial extension via pulmonary vein from metastatic
renal cell carcinoma who presented with left cerebellar and right thalamic
acute ischemic lesions along with multiple metastatic lesions.

Metastatik renal hücreli karsinomun pulmoner ven yoluyla sol atriyuma uzanımı: Bir olgu sunumu

Öz

Renal hücreli karsinomun kardiyak tutulumu nadir ancak iyi bilinen bir
olgudur ve literatürde bir çok vaka bildirilmiştir. Tümör çoğu durumda, sağ
kalp boşluklarına vena kava inferiyor içinde neoplastik trombüs yoluyla ulaşır.  Bu mekanizma dışında, kardiyak tutulum,
hematojen yolla olabileceği gibi, mediyastinal veya akciğer lezyonlarının pulmoner
venler yoluyla direk yayılımı ile de ortaya çıkabilir. Ancak vena kava inferiyor
tutulumu olmaksızın tümörün sol kalbe ulaşması son derece nadirdir.  Renal hücreli karsinomun akciğer metastazlarının,
pulmoner venler yoluyla sol atriyuma direk
uzanımı daha da nadirdir.

Bu makalede, çok sayıda
metastatik lezyonu olan ve sol serebellar ve sağ talamik akut iskemik
lezyonlara bağlı belirtileri ortaya çıkan, 
pulmoner ven yoluyla sol atriyuma direk uzanımı olan metastatik renal
hücreli karsinom olgusunu sunuyoruz.
