title: Traumatic right atrial pseudoaneurysm.
abstract: Pseudoaneurysm is defined as contained blood pooling due to rupture of vascular wall. They have higher risk of rupture and hence are usually managed aggressively. Trauma, infection and prior surgery are the most common etiologies for pseudoaneurysm of most sites. Traumatic cardiac pseudoaneurysm are rare and poses a diagnostic challenge to the treating physician since there is no specific symptoms associated with pseudoaneurysm and electrocardiogram; cardiac enzymes and echocardiogram may be unrevealing or inconclusive in many cases. Cross-sectional imaging [computed tomography (CT) and magnetic resonance imaging (MRI)] is done in cases with high index of suspicion and is the standard modality for diagnosis for cardiac pseudoaneurysm. We present a case of conservatively managed post-traumatic right atrial pseudoaneurysm with aim to highlight the role of electrocardiography (ECG)-gated multidetector computed tomography (MDCT) in diagnosis and follow-up of this rare entity that ultimately underwent rapid partial thrombosis.
