The presence of tumor thrombus in patients with lung cancer confers a risk of stroke and other end-organ ischemic events. This case highlights a potential role for electrocardiogram (ECG)-gated computed tomography (CT) in the diagnosis of this pathologic process. In this case, pulmonary vein thrombus was definitively identified by an ECG-CT following discordant results between CT and transthoracic echocardiogram. In addition, this case demonstrates how management decisions are affected by physician accessibility to and familiarity with specific imaging tests.
Abbreviations:CT (Computed tomography), MRI (Magnetic resonance imaging), DWI (Diffusion weighted imaging), TTE (Transthoracic echocardiogram), ECG (Electrocardiogram), TEE (Transesophageal echocardiogram), ICU (Intensive care unit)
