Cardiac MRI Detection of Left Ventricular Aneurysm in Children After Ventricular Assist Device Explantation

Consensus is lacking regarding screening for complications such as ventricular aneurysms after ventricular assist device explant. We report two pediatric patients, status-post explantation, who developed true left ventricular apical aneurysms diagnosed by cardiac magnetic resonance imaging. Imaging also suggested laminated thrombus versus postoperative changes which were treated with antiplatelet therapy.

Neoplastic zebras of venous thrombosis: Diagnostic challenges in vascular medicine

Venous thrombosis is a common medical problem. Imaging differentiation of neoplasms and venous clots may prove challenging. We report three cases of “mistaken identities” of venous thrombi and neoplasms on the basis of clinical findings and different imaging modalities: ultrasound, computed tomography, and magnetic resonance imaging. Imaging studies are not always reliable and consideration of clinical features, including pretest probability, is necessary for correct diagnosis. A combination of imaging modalities and biopsies is needed for correct diagnosis in some cases.
