“…Right atrial pseudoaneurysms are rare. Causes may be posttraumatic, secondary to invasive tumor, or iatrogenic (24)(25)(26)(27). The imaging features can be indistinguishable from those of a true aneurysm, and, often, differentiation can be determined only with pathologic confirmation (Fig 10).…”

Knowledge of right atrial anatomic and pathologic imaging findings and associated clinical symptoms is important to avoid false-positive diagnoses and missed findings. Complete evaluation of the heart often requires a multimodality approach that includes radiography, echocardiography, computed tomography (CT), magnetic resonance (MR) imaging, and invasive angiography. In general, CT provides the highest spatial resolution of these modalities at the cost of radiation exposure to the patient. Echocardiography and MR imaging offer complementary and detailed information for functional evaluation without added radiation exposure. The advantages and disadvantages of each modality for the evaluation of right atrial anatomic structure, size, and pathologic findings are discussed. Cardiac MR imaging is the reference standard for evaluation of right atrial size and volume but often is too time consuming and resource intensive to perform in routine clinical practice. Therefore, established reference ranges for two-dimensional transthoracic echocardiography are often used. Right atrial pathologic findings can be broadly categorized into (a) congenital anomalies (cor triatriatum dexter, Ebstein anomaly, and aneurysm), (b) disorders of volume (tricuspid regurgitation, pathologic mimics such as a pseudoaneurysm, and atrial septal defect), (c) disorders of pressure (tricuspid stenosis, restrictive cardiomyopathy, and constrictive pericarditis), and (d) masses (pseudomasses, thrombus, lipomatous hypertrophy of the interatrial septum, lipoma, myxoma, sarcoma, and metastatic disease). Familiarity with each pathologic entity and its treatment options is essential to ensure that appropriate imaging modalities are selected. Online supplemental material is available for this article.

“…This is in distinction to an aneurysm, in which there is dilatation of the chamber but all layers of the wall are intact. Treatment is controversial because some physicians argue that the low pressure of the right atrium poses minimal risk for rupture and that surgical repair is unnecessary (26).…”

“…Atrial aneurysms are much less common than ventricular aneurysms. Right atrial pseudoaneurysm (RAP) is a very rare condition that can be seen after cardiac surgery, blunt trauma or pericardial interventions [1][2][3] . RAP is usually a cystic cavity formed in the pericardium or prolipherative fibrous tissue after local rupture of the heart cavity which is often accompained by mural thrombus.…”

“…RAP is very rare. There have been only a few cases of RAP appearing after chest trauma 2 , cardiac surgery and interventions 1,3 , and malignancy 7 . Probably one of the reasons behind the scarcity of reports describing it is the difficulty in its diagnosis and its fatal prognosis.…”

Kovid-19 pnömonisinden şüphelenilen ve ilk olarak akciğer bilgisayarlı tomografisinde pnömoni lezyonları tespit edilen bir hasta kardiyomegali nedeniyle transtorasik ekokardiyografi ile ayrıca değerlendirildi. Transtorasik ekokardiyografide sağ atriyumla ilişkili büyük bir rüptüre psödoanevrizma saptandı. Kontrastlı bilgisayarlı tomografide sağ atriyal psödoanevrizmada iki taraflı çok sayıda akciğer nodülü ve mural trombüs ile ilişkili pulmoner emboli görüldü.
