Pseudoaneurysms are secondary to the disruption of vascular wall continuity and are characterized by a cystic structure and swirling blood flow inside. They are commonly seen in contemporary medical practice secondary to increased interventional procedures and trauma. Several causative factors have been identified, and radiologists today must be concerned about their presence during daily routine practice. Although the inguinal area is the most common site because of arterial punctures of the femoral arteries, involvement of every vascular structure of the body has been reported. Treatment options depend on several factors, with size and location being the decisive ones. Pseudoaneurysms that are small and in atypical locations may be clinically occult and pose a diagnostic challenge. This report describes a pseudoaneurysm of the geniculate branch of the popliteal artery.
