Renal vein thrombosis and asymptomatic massive pulmonary embolism: case presentation and diagnostic recommendations.

Isolated renal vein thrombosis is a rare radiographic finding. We present a patient whose complaint of flank pain led to the diagnosis of a renal vein thrombosis and uncovered massive pulmonary emboli. In this case, computed tomography (CT) of the chest was helpful in diagnosing the pulmonary emboli that were asymptomatic and allowed clinical management to be properly directed.
