Abstract

We report a case of a 39-year-old woman who died of fulminant pulmonary thromboembolism (PE). Autopsy showed classical findings of fulminant PE with occlusion of the bilateral main stem pulmonary arteries. Ancillary testing revealed inherited thrombophilia (Prothrombin 20,210 G > A and MTHFR 677 C > T mutation). Pre-autopsy postmortem computed tomography was used to test whether virtual imaging studies alone (virtual autopsy) would be sufficient to detect PE. Our studies show that computed tomography (CT) can differentiate antemortem clots from a postmortem clot in certain cases, particularly when combined with magnetic resonance imaging (MRI), which is superior in the assessment of soft tissue. We show that postmortem CT and MRI can aid in the diagnosis of pulmonary embolism by virtual autopsy, especially when used in conjunction.
