Catastrophic Antiphospholipid Syndrome: Scintigraphic Demonstration With Correlated Cross-Sectional Imaging

We present the case of catastrophic antiphospholipid syndrome occurring in a 44-year-old woman with a recent history of coronary artery bypass surgery. Postoperatively, she was urgently readmitted for a left middle cerebral artery stroke, and during workup she was found with a left ventricular thrombus on echocardiogram. Subsequently, the patient was diagnosed with antiphospholipid syndrome. Multimodality imaging, including bone and myocardial perfusion scintigraphy, CT, and MR, during her hospitalization, depicted all the characteristic features constituting the catastrophic form of antiphospholipid syndrome, also known as Asherson syndrome.
