“…Conventional trans-thoracic or trans-esophageal cardio-echograms are technician-dependent and limited in different ways [ 9 , 10 ]. As higher spatial and temporal resolution imaging rapidly develops, MDCT can provide better visualization of heart, great vessels, and lungs [ 9 – 11 ], and may be an alternative way to detect the origin of cardioembolic stroke in clinical applications.…”

Patient: Male, 46Final Diagnosis: Adenocarcinoma of the ascending colonSymptoms: Anemia • diplopia • hemiparesis • slurred speechMedication: —Clinical Procedure: Multi-detector computed tomography • colonoscopySpecialty: NeurologyObjective:Rare co-existance of disease or pathologyBackground:It is rare that occult cancer presents with frequent ischemic stroke as the sole manifestation.Case Report:We report the case of a 46-year-old man with frequent stroke in different vascular areas, with diabetes and hypercholesterolemia identified as risk factors. The results of biochemistry, young stroke profiles, trans-cranial and extra-cranial carotid Doppler, and 24-h Holter electrocardiogram were within normal limits. The reports of transthoracic echocardiography (TTE) were unremarkable. Finally, a multi-detector computed tomography (MDCT) demonstrated a thrombus in the posterior-lateral aspect of the left atrium and non-bacterial thrombotic endocarditis (NBTE) was suspected. The results motivated the survey for occult cancer, and adenocarcinoma of the ascending colon was confirmed on colonoscopy pathology.Conclusions:We suggest that evaluating the possibility of occult cancer should be emphasized in patients of frequent stroke refractory to therapy, whether risk factors are already identified or not. Furthermore, we assume MDCT can be an alternative way to detect cardiogenic embolic sources in stroke patients.

“…Thrombus appears as a low-attenuation filling defect, most-likely posterior in the LA, on CT, although the effects of contrast medium mixing due to slow flow and prominent trabeculations within the LAA can sometimes produce a similar appearance [14]. Delayed contrast-enhanced MRI and prone positioning are useful in cases of diagnostic uncertainty [14] (Figs. 4,5,6).…”

Cardiovascular sources of systemic embolism: detection and characterization using multidetector CT and MR imaging

The purpose of this article is to provide a current review of multidetector CT (MDCT) and MRI findings and imaging protocols for the cardiovascular diseases that can precipitate systemic embolism. These conditions include intracardiac thrombus or tumors, paradoxical embolism through right-to-left shunts, and diseases of the thoracic aorta. MDCT and MRI may be helpful for detection of these conditions. Familiarity with the pathogenesis and CT and MRI appearance of these conditions is important as their detection may have a major impact on patient management.
