In this paper, the authors present the case of coexistence of common pathologies of the cardiovascular system in a patient with pain in the right lower limb. The presented images provide a didactically valuable overview of serious cardiovascular pathologies. This article highlights the value of computed tomography angiography in diagnosis of cardiovascular life-threatening conditions, especially as a result of proper medical interview and physical examination.
