title: Neoplastic zebras of venous thrombosis: Diagnostic challenges in vascular medicine.
abstract: 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.
